From c767ababacc83101ec5394564327ce6bd2b78107 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 12 Nov 2025 21:20:00 +0000 Subject: [PATCH 01/48] Rebuild app for ARM64 (Apple Silicon) support Convert MultiSoundChanger from x86_64-only to universal binary supporting both Intel and Apple Silicon Macs. Changes: - Replace x86_64-only OSD.framework with native Swift implementation - Remove EXCLUDED_ARCHS = arm64 from build configurations - Add NativeOSDManager.swift with full OSD functionality - Update bridging header to remove OSD.framework dependency - Add comprehensive ARM64 migration documentation The new NativeOSDManager provides: - Custom NSWindow-based volume indicator overlay - Speaker and muted speaker icons - Animated volume chiclets - Multi-monitor support - Smooth fade animations Architecture support: - x86_64 (Intel Macs) - arm64 (Apple Silicon: M1, M2, M3, M4) Tested functionality: - Audio device enumeration - Volume control for standard and aggregate devices - Media key handling - On-screen volume indicator display --- ARM64_MIGRATION.md | 219 +++++++++++++ MultiSoundChanger.xcodeproj/project.pbxproj | 10 +- .../Other/MultiSoundChanger-Bridging-Header.h | 2 +- .../Sources/Frameworks/NativeOSDManager.swift | 306 ++++++++++++++++++ README.md | 9 +- 5 files changed, 538 insertions(+), 8 deletions(-) create mode 100644 ARM64_MIGRATION.md create mode 100644 MultiSoundChanger/Sources/Frameworks/NativeOSDManager.swift diff --git a/ARM64_MIGRATION.md b/ARM64_MIGRATION.md new file mode 100644 index 0000000..bb25947 --- /dev/null +++ b/ARM64_MIGRATION.md @@ -0,0 +1,219 @@ +# ARM64 Migration Guide + +## Overview + +This document describes the changes made to rebuild MultiSoundChanger for ARM64 (Apple Silicon) architecture. + +## Changes Made + +### 1.

Synchronous window creation and display (no async) 2. Set isReleasedWhenClosed = false (manual memory management) 3. Store strong reference in OSDManager 4. Removed NSAnimationContext.runAnimationGroup 5. Use simple animator().alphaValue for fade 6. Single weak self in timer callback 7. Use asyncAfter instead of completion handlers 8. Cleanup calls orderOut immediately 9. No nested async dispatches Window lifecycle now: 1. Create window synchronously 2. Show immediately with alphaValue = 1.0 3. Timer fires -> fadeOut() 4. Fade with animator().alphaValue = 0 5. asyncAfter 0.3s -> orderOut() 6.

reuse window; clean up dead code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses PR #39 review feedback from @wodin: - Replace makeKeyAndOrderFront(nil) with orderFrontRegardless() so the OSD no longer activates the app or yanks focus from the user's current window. - Reuse a single OSDWindow across volume events instead of recreating on each press — eliminates flicker/tearing under rapid hotkey spam and removes the lifecycle race that fueled the recent crash-fix churn. - Log a warning when the NSScreen for the given displayID can't be found instead of falling back silently. - Remove unused `_ = NSGraphicsContext.current?.cgContext` probe. - Remove the dead `NSScreen.screens.first(where: { $0 == screen })` guard. - Wrap the alpha fade in NSAnimationContext.runAnimationGroup so the orderOut() step fires in the animation completion handler instead of a hardcoded 0.3s asyncAfter that could race the animator. - Make the OSDManager singleton thread-safe via `static let instance` (dispatch_once semantics) instead of a non-atomic shared var. - Drop the unused OSDGraphic enum cases (.backlight, .eject, .noWiFi, .keyboardBacklight*, .macProOpen, .hotspot, .sleep) — we only render speaker and speakerMuted.

See `ARM64_MIGRATION.md` for the full migration history. + +## Build / Run + +**Always open `MultiSoundChanger.xcworkspace`, not `MultiSoundChanger.xcodeproj`.** The app depends on CocoaPods (SwiftLint, MediaKeyTap), so building through the `.xcodeproj` directly will fail. + +```bash +pod install # first-time or after Podfile changes +open MultiSoundChanger.xcworkspace # then ⌘B / ⌘R in Xcode +``` + +Command-line build (universal): +```bash +xcodebuild -workspace MultiSoundChanger.xcworkspace \ + -scheme MultiSoundChanger -configuration Release \ + -arch "x86_64 arm64" clean build +``` + +Lint: SwiftLint runs as a build phase (configured by `.swiftlint.yml`, which uses an explicit `whitelist_rules` allowlist rather than the default rule set). `Pods/` is excluded. + +There is no test target. + +## Architecture + +The app is a status-bar-only Cocoa app (no main window).

Stick to that pattern when adding components. + +### Aggregate-device handling (the core feature) + +`AudioManagerImpl` checks `audio.isAggregateDevice(deviceID:)` on every volume/mute operation. For aggregates it fans out: `getAggregateDeviceSubDeviceList` → iterate → apply `setDeviceVolume` / `setDeviceMute` to each sub-device. The *getter* path is asymmetric — it returns `audio.getDeviceVolume(…).max()` from the first output sub-device rather than aggregating. Preserve this fan-out-on-write / read-one-sub-device model when touching `AudioManager` or `Audio.swift`. + +### OSD (ARM64-critical) + +The original app linked `OSD.framework` (private Apple framework, x86_64-only), which blocked ARM64. It was replaced by `Sources/Frameworks/NativeOSDManager.swift`, a pure-Swift reimplementation exposing an `@objc` class **named `OSDManager`** with a `sharedManager()` / `showImage(...)` API that matches the original framework's signature. `MediaManager` calls this as if the framework still exists — do not rename `OSDManager` or change its method shape without also updating `MediaManager.showOSD`. + +The on-disk `OSD.framework/` directory is a leftover and is no longer referenced by `project.pbxproj`; do not re-add it. The bridging header (`MultiSoundChanger-Bridging-Header.h`) likewise no longer imports it. + +### MediaKey flow + +`MediaManagerImpl` uses a custom fork of MediaKeyTap (pinned in `Podfile` to `the0neyouseek/MediaKeyTap` master). It requires Accessibility permission; the app prompts via `AXIsProcessTrustedWithOptions` on startup and re-calls `startMediaKeyTap()` when it observes `com.apple.accessibility.api` DistributedNotification (so permission changes take effect without relaunch). Key events route: MediaKeyTap → `MediaManagerDelegate` → `ApplicationControllerImp.onMediaKeyTap` → `AudioManager` + `StatusBarController.updateVolume` + `MediaManager.showOSD`. + +Volume is quantized to `Constants.chicletsCount` (16) steps so hardware key presses align with OSD chiclets. + +## Conventions + +- Swift-only source lives under `MultiSoundChanger/Sources/`; non-code assets and `Constants.swift` under `MultiSoundChanger/Other/`. +- UI is storyboard-based (`Volume.storyboard`, `Main.storyboard`). View controllers are loaded via the `Stories` enum helper, which instantiates by `String(describing: classType)` — so storyboard identifiers **must match the class name exactly**. +- All user-visible strings go through `Strings.*` (see `Other/Localization/`); log/debug strings go through `Constants.InnerMessages`. +- Logging: use `Logger.debug / info / warning / error`.

Both Main and Master are defined as element 0 in CoreAudio and the value has been stable for the life of the HAL, so inline the literal `0` with a comment explaining the invariant. - Remove the private `getDeviceType` helper entirely.

Every other getter/setter silently ate failures, so a device that disappeared mid-operation (unplugged USB DAC, Bluetooth drop) would return zero-initialized garbage — empty device lists, volume arrays of [0,0,0], transport type 0 — with no diagnostic trail. Add a `check(_ status: OSStatus, _ op: String)` helper that: - Returns true on noErr, false otherwise. - Logs failures via Logger.warning with the operation label and numeric status code. - Rate-limits duplicates on a 2-second cooldown keyed by (op, status), guarded by a serial DispatchQueue, so a dead device can't flood the log at hotkey autorepeat speed. Wrap all 24 call sites in `AudioImpl`: - Collection getters (`getAllDevices`, `getAggregateDeviceSubDeviceList`) short-circuit to `[]` on failure instead of returning a partially- zeroed buffer that a caller could iterate. - `getDeviceVolume` and `setDeviceVolume` now skip the Set/Get when the size probe fails for that element, so a bad master element doesn't preempt the L/R channels (and vice versa).

Plugging in a USB DAC, changing the default output in System Settings, or unplugging the current default all left the app in a stale state until the user quit and relaunched. Register two `AudioObjectAddPropertyListenerBlock` listeners: - `kAudioHardwarePropertyDevices` — hardware topology changes. On fire, re-enumerate output devices. If the currently selected device is no longer present, fall back to the system default so hotkeys keep a valid target. - `kAudioHardwarePropertyDefaultOutputDevice` — the user (or another app) switched the system default elsewhere. On fire, let the menu re-highlight the new default and reselect it locally so volume hotkeys control the same device macOS is routing to. Plumbing: - `Audio` protocol gains `addDevicesListener`, `addDefaultOutputDeviceListener`, and `removeListener(_:)`. Blocks run on a private serial dispatch queue and immediately `DispatchQueue.main.async` before invoking the caller's closure — NSMenu/NSStatusItem mutations stay main-thread only. Returns opaque `AudioListenerToken` so the HAL can match the exact block pointer at removal time. - `AudioManager` protocol gains a weak `delegate: AudioManagerDelegate?` with `devicesDidChange` / `defaultOutputDidChange` callbacks. AudioManagerImpl registers both hardware listeners in `init` and tears them down in `deinit` via the tokens it stored. Listener blocks capture `[weak self]` to avoid keeping the manager alive past its natural lifetime. - `StatusBarController` protocol gains `refreshDeviceList()` and `syncDefaultOutputDevice()`. Implementation now tracks `deviceMenuItems: [NSMenuItem]` and an `outputSectionAnchor` so a rebuild removes exactly the old device rows and inserts the new ones immediately below the "Output Device:" header — preserving the surrounding separators / Sound Preferences / Quit structure. `menuItemAction` also now iterates `deviceMenuItems` directly instead of walking the whole menu. - `ApplicationControllerImp` conforms to `AudioManagerDelegate` and wires `audioManager.delegate = self` after `createMenu()`, so the initial menu build isn't racing a listener callback. `devices` in AudioManagerImpl changes from `let` to `var` so the refresh can replace it; all getter callers continue to receive the cached dictionary. --- .../Classes/ApplicationController.swift | 15 +- .../Sources/Classes/AudioManager.swift | 43 ++++- .../Sources/Classes/StatusBarController.swift | 150 +++++++++++------- .../Sources/Frameworks/Audio.swift | 59 +++++++ 4 files changed, 204 insertions(+), 63 deletions(-) diff --git a/MultiSoundChanger/Sources/Classes/ApplicationController.swift b/MultiSoundChanger/Sources/Classes/ApplicationController.swift index 31cf379..1a51a1a 100644 --- a/MultiSoundChanger/Sources/Classes/ApplicationController.swift +++ b/MultiSoundChanger/Sources/Classes/ApplicationController.swift @@ -21,13 +21,26 @@ final class ApplicationControllerImp: ApplicationController { private lazy var audioManager: AudioManager = AudioManagerImpl() private lazy var mediaManager: MediaManager = MediaManagerImpl(delegate: self) private lazy var statusBarController: StatusBarController = StatusBarControllerImpl(audioManager: audioManager) - + func start() { statusBarController.createMenu() + audioManager.delegate = self mediaManager.listenMediaKeyTaps() } } +// MARK: - AudioManagerDelegate + +extension ApplicationControllerImp: AudioManagerDelegate { + func audioManagerDidChangeDevices(_ manager: AudioManager) { + statusBarController.refreshDeviceList() + } + + func audioManagerDidChangeDefaultOutputDevice(_ manager: AudioManager) { + statusBarController.syncDefaultOutputDevice() + } +} + // MARK: - MediaManagerDelegate extension ApplicationControllerImp: MediaManagerDelegate { diff --git a/MultiSoundChanger/Sources/Classes/AudioManager.swift b/MultiSoundChanger/Sources/Classes/AudioManager.swift index 97678db..0159491 100644 --- a/MultiSoundChanger/Sources/Classes/AudioManager.swift +++ b/MultiSoundChanger/Sources/Classes/AudioManager.swift @@ -11,6 +11,11 @@ import Foundation // MARK: - Protocols +protocol AudioManagerDelegate: AnyObject { + func audioManagerDidChangeDevices(_ manager: AudioManager) + func audioManagerDidChangeDefaultOutputDevice(_ manager: AudioManager) +} + protocol AudioManager: AnyObject { func getDefaultOutputDevice() -> AudioDeviceID func getOutputDevices() -> [AudioDeviceID: String]?

Fixes in this commit: Audio.swift - `addHardwareListener` returns `AudioListenerToken?` (was non-optional). If `AudioObjectAddPropertyListenerBlock` fails we now return nil instead of handing back a token that will later call RemovePropertyListenerBlock with a block the HAL never registered. Protocol signatures updated in lockstep; `AudioManagerImpl` unwraps via `if let`. - Rate-limiter dict is now capped at 64 (op, status) keys. If a pathological device floods new status codes, the dict clears before it can grow unbounded. AudioManager.swift - Init and the hot-plug fallback in `handleDevicesChanged` now check for `kAudioDeviceUnknown` before assigning `selectedDevice`. A HAL-side failure no longer leaves the app pointed at an invalid device ID so hotkeys can still early-return cleanly. - Adds `followSelectedDevice(deviceID:)` — mirrors `selectDevice` but omits the `audio.setOutputDevice` call, so the default-output listener callback can't recurse when we update local state to reflect an already-applied system change. StatusBarController.swift - `StatusBarControllerImpl` now inherits `NSObject` so it can serve as `NSMenuDelegate`. Tracks `isMenuOpen` / `pendingRefresh` via `menuWillOpen` and `menuDidClose`. `refreshDeviceList` defers the rebuild if the user has the menu open; it runs on close. No more mutating an NSMenu mid-tracking. - `syncDefaultOutputDevice` guards against `kAudioDeviceUnknown` and uses the new `followSelectedDevice` path instead of `selectDevice`, which eliminates the theoretical infinite loop where setting the default output to itself refires its own listener. - `createMenu` now clears `deviceMenuItems` and resets `outputSectionAnchor` before rebuilding, defensively handling a second call (shouldn't happen, but the state would otherwise leak references to stale NSMenuItems). - `populateDeviceList` anchor-not-found path now logs a warning and skips the rebuild instead of silently appending device items after the Quit item at the bottom of the menu. ApplicationController.swift - `start()` wires `audioManager.delegate = self` before calling `statusBarController.createMenu()` so an unlucky HAL-listener firing during construction finds the delegate connected by the time its main-queue continuation runs.

Fixes in this commit: Logger.swift (HIGH — every log line was mislabelled) - getDebugLine shadowed its own `symbol` parameter with `let symbol = DebugSymbol.info.rawValue`, so every call path (debug/info/warning/error) rendered with the blue info glyph. - outAndFilePrint passed `.error` to outPrint and `.info` to filePrint, hard-coding both regardless of the caller's intent. Pass the symbol through everywhere; the debug/warning/error level actually shows up in the log now. AudioManager.swift toggleMute (HIGH — unmute trap at volume=0) - Previous implementation unmuted then re-read volume and re-applied it. On drivers that zero the volume scalar while muted, or when the user happened to be at volume 0 when muting, the re-apply of 0 tripped `setSelectedDeviceVolume`'s auto-mute-below-lowerbound branch and immediately re-muted. User appeared stuck on mute. - Drop the re-apply. Only flip the mute flag. The device's scalar volume is preserved by the driver (or left at 0 by user choice) and the next volume-up / slider drag restores audio if needed. NativeOSDManager.swift (LOW — OSD overlapped menu bar) - Switch repositionOn from `screen.frame` to `screen.visibleFrame` so the OSD respects the menu bar and dock on the primary display. VolumeViewController.swift — remove unused imports - `import AudioToolbox` and `import MediaKeyTap` were left over from earlier versions; the VC only uses Cocoa + the in-module AudioManager protocol. Main.storyboard — fix stale `customModule="DynamicsIllusion"` - The AppDelegate customObject still pointed at a pre-fork module name. Swap to `MultiSoundChanger`. AppKit resolved the class via @NSApplicationMain registration anyway, but the storyboard ref would bite if anyone ever relied on module-qualified lookup. Also strips trailing whitespace from AppDelegate.swift, Logger.swift, Runner.swift, Stories.swift, VolumeViewController.swift, Constants.swift, and Images.swift — the P3 SwiftLint sweep flagged leftover trailing whitespace across these pre-existing files. --- MultiSoundChanger/Other/Constants.swift | 16 ++++---- .../Sources/AppDelegate/AppDelegate.swift | 2 +- .../Sources/Classes/AudioManager.swift | 7 +++- .../Sources/Frameworks/NativeOSDManager.swift | 4 +- .../Sources/Stories/Stories.swift | 4 +- .../Stories/Volume/VolumeViewController.swift | 8 ++-- MultiSoundChanger/Sources/Utils/Logger.swift | 41 +++++++++---------- MultiSoundChanger/Sources/Utils/Runner.swift | 8 ++-- 8 files changed, 46 insertions(+), 44 deletions(-) diff --git a/MultiSoundChanger/Other/Constants.swift b/MultiSoundChanger/Other/Constants.swift index a6ea1b1..4913711 100644 --- a/MultiSoundChanger/Other/Constants.swift +++ b/MultiSoundChanger/Other/Constants.swift @@ -13,25 +13,25 @@ enum Constants { static let optionMaxLength = 25 static let muteVolumeLowerbound: Float = 0.001 static let logFilename = "app.log" - + enum AppBundleIdentifier { static let systemPreferences = "com.apple.systempreferences" static let audioDevices = "com.apple.audio.AudioMIDISetup" } - + enum SystemPreferencesPane { static let sound = "/System/Library/PreferencePanes/Sound.prefPane" } - + enum Notifications { static let accessibility = "com.apple.accessibility.api" } - + enum Keys: String { case empty = "" case q } - + enum InnerMessages { static let accessEnabled = "Access enabled" static let accessDenied = "Access denied" @@ -39,15 +39,15 @@ enum Constants { static let outputDevices = "Output devices" static let bundleIdentifierError = "Can't get bundle identifier" static let controllerIdentifierError = "Wrong controller identifier" - + static func debugDevice(deviceID: String, deviceName: String) -> String { return "id: \(deviceID) | name: \(deviceName)" } - + static func selectDevice(deviceID: String) -> String { return "Select device id: \(deviceID)" } - + static func selectedDeviceVolume(volume: String) -> String { return "Selected device volume: \(volume)" } diff --git a/MultiSoundChanger/Sources/AppDelegate/AppDelegate.swift b/MultiSoundChanger/Sources/AppDelegate/AppDelegate.swift index 7ff7d4d..f9d298d 100644 --- a/MultiSoundChanger/Sources/AppDelegate/AppDelegate.swift +++ b/MultiSoundChanger/Sources/AppDelegate/AppDelegate.swift @@ -11,7 +11,7 @@ import Cocoa @NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate { private let applicationController: ApplicationController = ApplicationControllerImp() - + func applicationDidFinishLaunching(_ aNotification: Notification) { applicationController.start() } diff --git a/MultiSoundChanger/Sources/Classes/AudioManager.swift b/MultiSoundChanger/Sources/Classes/AudioManager.swift index 7279b82..04cf327 100644 --- a/MultiSoundChanger/Sources/Classes/AudioManager.swift +++ b/MultiSoundChanger/Sources/Classes/AudioManager.swift @@ -160,9 +160,12 @@ final class AudioManagerImpl: AudioManager { func toggleMute() { if isSelectedDeviceMuted() { + // Only flip the mute flag.

Cosmetic but flagged by pass-4 audit. AudioManager.swift — restore volume after unmute on drivers that zero the scalar during mute - Pass-3 simplified toggleMute to "only flip the mute flag" to escape the 0-volume re-mute trap. That was correct for avoiding the auto- mute branch, but on drivers that zero the VolumeScalar while muted (a subset of USB DACs, aggregates, some virtual drivers) the post- unmute scalar is still 0 — so audio is silent and the UI correctly shows 0%, but from the user's perspective "unmute did nothing". - Capture the pre-mute volume in a new private `volumeBeforeMute` when entering the muted state. On unmute, if the post-unmute scalar reads back as below the auto-mute lowerbound AND the stored pre-mute value was above that lowerbound, re-apply the pre-mute value via setSelectedDeviceVolume. The guard on `pre >= lowerbound` keeps us from falling back into the auto-mute trap when the user deliberately muted from near-zero. --- .../Sources/Classes/AudioManager.swift | 20 ++++++++++++++----- .../Sources/Classes/MediaManager.swift | 4 ++-- MultiSoundChanger/Sources/Utils/Logger.swift | 2 +- 3 files changed, 18 insertions(+), 8 deletions(-) diff --git a/MultiSoundChanger/Sources/Classes/AudioManager.swift b/MultiSoundChanger/Sources/Classes/AudioManager.swift index 04cf327..05cd3b2 100644 --- a/MultiSoundChanger/Sources/Classes/AudioManager.swift +++ b/MultiSoundChanger/Sources/Classes/AudioManager.swift @@ -42,6 +42,7 @@ final class AudioManagerImpl: AudioManager { private var devices: [AudioDeviceID: String]? private var selectedDevice: AudioDeviceID? private var listenerTokens: [AudioListenerToken] = [] + private var volumeBeforeMute: Float? init() { devices = audio.getOutputDevices() @@ -160,13 +161,22 @@ final class AudioManagerImpl: AudioManager { func toggleMute() { if isSelectedDeviceMuted() { - // Only flip the mute flag.

Audio.swift — fix UnsafeMutableRawPointer→CFString warning - `getDeviceName` was passing `&result` where `result: CFString`. ARC doesn't track storage for CF reference types stored as Swift values, so forming a raw pointer was technically undefined and the compiler was right to warn. Switch to the `Unmanaged?` pattern that CoreFoundation expects: the property-data call writes a +1-retained pointer which we unwrap via `takeRetainedValue()`. No more warning, no leaks, same resulting `String`. Logger.swift — stop blocking main on file I/O - `outAndFilePrint` was doing `FileManager.default.url(...)`, `FileHandle(forWritingTo:)`, `seekToEndOfFile`, `write`, `closeFile` synchronously on whatever thread the caller (usually main) was on. That's real latency per log line, and `ApplicationController.onMediaKeyTap` emits a `Logger.debug` per volume keypress — so rapid volume-up/down could stutter the UI behind the disk. Funnel writes through a dedicated serial `fileWriteQueue` async dispatch; stdout still prints synchronously so interactive debugging is unchanged, and any file-write error surfaces back on main. NativeOSDManager.swift — skip the main→main runloop hop - `OSDManager.showImage` unconditionally did `DispatchQueue.main.async { … displayOSD(…) }`. When (as in the volume-hotkey path) the caller is already on main, that defers OSD appearance by a full runloop tick, which is visible. Branch on `Thread.isMainThread`: call `displayOSD` synchronously if we're already there, otherwise keep the `main.async` fallback for any future non-main caller. Podfile — silence third-party warnings - MediaKeyTap's fork and SwiftLint both emit deprecation warnings (`class` keyword on class-constrained protocols, etc.) that we can't fix without forking. Set `:inhibit_warnings => true` on both so the Xcode build log stays focused on our own warnings. Requires `pod install` once to re-apply. --- .../Sources/Frameworks/Audio.swift | 17 +++++++++----- .../Sources/Frameworks/NativeOSDManager.swift | 23 +++++++++++++++---- MultiSoundChanger/Sources/Utils/Logger.swift | 17 ++++++++++---- Podfile | 6 +++-- 4 files changed, 47 insertions(+), 16 deletions(-) diff --git a/MultiSoundChanger/Sources/Frameworks/Audio.swift b/MultiSoundChanger/Sources/Frameworks/Audio.swift index e2e330c..3ae485e 100644 --- a/MultiSoundChanger/Sources/Frameworks/Audio.swift +++ b/MultiSoundChanger/Sources/Frameworks/Audio.swift @@ -359,21 +359,26 @@ final class AudioImpl: Audio { } private func getDeviceName(deviceID: AudioDeviceID) -> String { - var propertySize = UInt32(MemoryLayout.size) + var propertySize = UInt32(MemoryLayout?>.size) var propertyAddress = AudioObjectPropertyAddress( mSelector: AudioObjectPropertySelector(kAudioDevicePropertyDeviceNameCFString), mScope: AudioObjectPropertyScope(kAudioObjectPropertyScopeGlobal), mElement: kAudioPropertyElement) - var result: CFString = "" as CFString + // CoreFoundation types (CFString here) must come back through `Unmanaged` — forming a raw + // pointer to a CFString-typed variable is undefined under ARC, which is what the + // "UnsafeMutableRawPointer to CFString" warning was flagging. + var name: Unmanaged? - check( - AudioObjectGetPropertyData(deviceID, &propertyAddress, 0, nil, &propertySize, &result), + guard check( + AudioObjectGetPropertyData(deviceID, &propertyAddress, 0, nil, &propertySize, &name), "getDeviceName:GetPropertyData" - ) + ), let name = name else { + return "" + } - return result as String + return name.takeRetainedValue() as String } private func getAllDevices() -> [AudioDeviceID] { diff --git a/MultiSoundChanger/Sources/Frameworks/NativeOSDManager.swift b/MultiSoundChanger/Sources/Frameworks/NativeOSDManager.swift index d0c1c20..d2d9d01 100644 --- a/MultiSoundChanger/Sources/Frameworks/NativeOSDManager.swift +++ b/MultiSoundChanger/Sources/Frameworks/NativeOSDManager.swift @@ -39,14 +39,29 @@ class OSDManager: NSObject { totalChiclets: UInt32, locked: Bool ) { - DispatchQueue.main.async { [weak self] in - self?.displayOSD( - graphic: OSDGraphic(rawValue: Int(image)) ?? .speaker, + let graphic = OSDGraphic(rawValue: Int(image)) ?? .speaker + let fadeDelay = TimeInterval(msecUntilFade) / 1_000.0 + // The media-key handler already runs on main, so invoking synchronously here avoids a + // full runloop tick of latency between the user pressing a volume key and the OSD + // appearing.

Audio.swift — halve HAL IPC on the volume hot path - `setDeviceVolume` was issuing one `AudioObjectGetPropertyDataSize` per element (master/L/R) before each `AudioObjectSetPropertyData`, just to learn a fact it already knew: the volume scalar is always `Float32`. Each probe is a round-trip to the HAL server. - `getDeviceVolume` had the same shape. - Drop the probes and hardcode `size = MemoryLayout.size`. On an aggregate device with N sub-devices, a single volume keypress went from 7N+ IPC round-trips down to 4N. That's the single biggest win available on this path. ApplicationController.swift — paint UI before writing to HAL - `onMediaKeyTap` was doing, in order: HAL write, then slider/ status-icon update, then OSD show. The HAL write dominates wall- clock time (IPC + fan-out to aggregate sub-devices), so the OSD didn't appear until everything else was done. - For `.volumeUp` / `.volumeDown` we already know the target volume before the HAL write — flip the order: paint the slider, icon, and OSD first via a new `paintVolumeFeedback(_:)` helper, THEN commit to HAL. The user sees the OSD come up immediately on keypress instead of after the CoreAudio round-trip completes. - `.mute` keeps its original order because the post-toggle mute state is what picks the OSD glyph, so the HAL write still has to come first there. VolumeViewController.swift — debounce the slider-drag HAL writes - NSSlider fires `volumeSliderAction` on every pixel of drag motion. Each fire was calling `audioManager?.setSelectedDeviceVolume(...)` synchronously on main, blocking the UI on CoreAudio IPC per event. During a drag that's dozens of IPC round-trips per second, which is exactly the jank you noticed. - Keep the status-bar icon update immediate (cheap, pure visual), but trailing-edge-debounce the HAL write by ~33ms via a cancellable DispatchWorkItem. A continuous drag cancels each scheduled write and schedules a fresh one; the HAL only gets the final value when the user pauses or releases.

Changes in AudioManagerImpl: - New `pendingTargetVolume: Float?` + `pendingApplyItem: DispatchWorkItem?` state. `setSelectedDeviceVolume(volume:)` now writes the target to `pendingTargetVolume`, cancels any still-scheduled work, and schedules a fresh `applyVolumeToHAL` call 33 ms later (1/30 s). Rapid key-repeat or continuous slider drag cancels every pending item; only the final value actually round-trips to CoreAudio. `onMediaKeyTap` returns immediately after painting the OSD/slider/icon — so MediaKeyTap's `main.sync` callback unblocks fast and key-repeats no longer queue up behind blocking HAL IPC. - `getSelectedDeviceVolume()` now prefers `pendingTargetVolume` over a HAL read. Without this, `onMediaKeyTap`'s quantize-against-current step would read the stale HAL value three times in a row during rapid up-up-up, compute the same next step each time, and the three keypresses would collapse to one visible step. Returning the pending target lets each keypress see the previous keypress's target and advance the step correctly. - New `readDeviceVolumeFromHAL()` helper is the direct-HAL-read path, used by `toggleMute`'s "did the driver zero the scalar during mute?" probe — that check needs to see the actual device state, not a cached user-intent. - `toggleMute`, `selectDevice`, `adoptSelectedDevice`, and `handleDevicesChanged` all cancel the pending apply before they run. Prevents a queued volume write from firing after mute/device-change and clobbering the new state via `applyVolumeToHAL`'s auto-mute branch. - `deinit` cancels the pending work item alongside removing listeners. Changes in VolumeViewController: - Remove the VC-local debounce (it's now handled one layer down) and the `halApplyItem` / `halApplyDelay` plumbing. `volumeSliderAction` shrinks back to the three-line "paint icon, forward value" shape it had before, while still getting per-pixel smoothness because `AudioManager` does the HAL coalescing. --- .../Sources/Classes/AudioManager.swift | 135 +++++++++++++----- .../Stories/Volume/VolumeViewController.swift | 22 +-- 2 files changed, 104 insertions(+), 53 deletions(-) diff --git a/MultiSoundChanger/Sources/Classes/AudioManager.swift b/MultiSoundChanger/Sources/Classes/AudioManager.swift index 7b9f5a9..d52dcba 100644 --- a/MultiSoundChanger/Sources/Classes/AudioManager.swift +++ b/MultiSoundChanger/Sources/Classes/AudioManager.swift @@ -43,6 +43,14 @@ final class AudioManagerImpl: AudioManager { private var listenerTokens: [AudioListenerToken] = [] private var volumeBeforeMute: Float? + // Coalesce rapid `setSelectedDeviceVolume` calls (media-key repeat, slider drag) into a + // single trailing-edge HAL write.

Every finding that had a concrete, low-risk fix is addressed; harder structural changes (Developer ID signing, Hardened Runtime, notarization, POSIX O_NOFOLLOW log writes) are left for a separate distribution-focused pass because they need infrastructure we don't have in this repo. SUPPLY CHAIN Podfile — pin MediaKeyTap to its current commit hash instead of `:branch => 'master'`. Without this, anyone with write access to the `the0neyouseek/MediaKeyTap` fork could push malicious code and have it land in our build on the next `pod install`. Podfile.lock captured the hash but couldn't enforce it against a fresh lockfile. Also bump `pod 'SwiftLint'` to `'~> 0.51'` so a breaking 1.x release can't walk in unnoticed. SUBPROCESS SURFACE ELIMINATION Runner.swift — delete `shell(_:)` entirely. The only caller (`menuSoundPreferencesAction`) shelled out to `/bin/sh -c "open -b com.apple.systempreferences /System/Library/PreferencePanes/Sound.prefPane"`. Fully replaced with `NSWorkspace.shared.open(URL(string: "x-apple.systempreferences:com.apple.preference.sound"))` — no subprocess, no shell interpretation, and it picks the right host (System Settings on Ventura+, System Preferences before). Drops `Constants.AppBundleIdentifier.systemPreferences` and `Constants.SystemPreferencesPane.sound`; adds `Constants.SystemSettingsURL.sound` for the new URL. MEMORY SAFETY Audio.swift — `AudioListenerToken.address` was `var`; nothing in the codebase mutated it, but a mutation between `addHardwareListener` and `removeListener` would silently orphan the HAL registration (the HAL matches on exact block + address pair). Make it `let`; `removeListener` copies into a local `var` for the `inout` pass to the HAL call. DENIAL OF SERVICE MediaManager.swift — DistributedNotificationCenter's `com.apple.accessibility.api` channel is open to every local process. The previous handler responded to each post by tearing down and recreating the CGEventTap via `startMediaKeyTap()`. A spoof flood could burn CPU and exhaust per-process event-tap limits. Debounce the handler with a cancellable DispatchWorkItem + 500 ms trailing edge — legitimate single toggles still fire one restart, floods collapse to one. LOG INTEGRITY AudioManager.swift — CoreAudio returns device names from user-chosen / plugin-chosen strings, which can contain `\n` / `\r` / `\t`. Those would otherwise inject fake log lines into `app.log` and confuse parsers. `printDevices` now routes device names through a local `sanitizedForLog(_:)` helper that maps the three control characters to spaces before handing them to `Logger.debug`. USER COMMUNICATION Info.plist — add `NSAccessibilityUsageDescription` explaining why the app requests Accessibility (to receive hardware volume / mute keys). macOS 14+ surfaces this string in the permission UI; its absence looks suspicious and may prevent notarized distribution. --- MultiSoundChanger/Other/Constants.swift | 8 +++++--- MultiSoundChanger/Other/Info.plist | 2 ++ .../Sources/Classes/AudioManager.swift | 13 +++++++++++- .../Sources/Classes/MediaManager.swift | 13 +++++++++++- .../Sources/Classes/StatusBarController.swift | 8 +++++++- .../Sources/Frameworks/Audio.swift | 12 +++++++++-- MultiSoundChanger/Sources/Utils/Runner.swift | 20 ------------------- Podfile | 9 +++++++-- 8 files changed, 55 insertions(+), 30 deletions(-) diff --git a/MultiSoundChanger/Other/Constants.swift b/MultiSoundChanger/Other/Constants.swift index 4913711..3fb4617 100644 --- a/MultiSoundChanger/Other/Constants.swift +++ b/MultiSoundChanger/Other/Constants.swift @@ -15,12 +15,14 @@ enum Constants { static let logFilename = "app.log" enum AppBundleIdentifier { - static let systemPreferences = "com.apple.systempreferences" static let audioDevices = "com.apple.audio.AudioMIDISetup" } - enum SystemPreferencesPane { - static let sound = "/System/Library/PreferencePanes/Sound.prefPane" + // x-apple.systempreferences: URL used to jump straight to the Sound pane in System Settings + // (modern macOS) or System Preferences (pre-Ventura).

HARDENED RUNTIME + ENTITLEMENTS Enable the Apple Hardened Runtime for both Debug and Release target configurations (ENABLE_HARDENED_RUNTIME = YES). Add a `MultiSoundChanger/Other/MultiSoundChanger.entitlements` file and wire it via CODE_SIGN_ENTITLEMENTS on both configs. The file is intentionally an empty dictionary: we're a pure Swift/AppKit menu-bar app with no JIT, no dylib injection, no outgoing Apple Events, and no debugger attach — so no Hardened-Runtime exceptions are required. `CODE_SIGN_IDENTITY = "-"` stays ad-hoc for local dev builds; shipping via Developer ID now just needs the cert + notarization, not a scramble to add Hardened Runtime after the fact. 2. LOGGER POSIX APPEND WITH O_NOFOLLOW Rewrite `Logger.appendToFile` from `FileHandle(forWritingTo:)` + the separate "fresh write if missing" branch to raw Darwin `open(path, O_WRONLY|O_APPEND|O_CREAT|O_NOFOLLOW, 0o600)` + `write` + `close`. Closes the symlink-race window the audit flagged: a local attacker planting `~/Library/Caches//app.log` as a symlink to `~/.ssh/id_rsa` would have caused the old FileHandle path to append log lines into the target file. O_NOFOLLOW makes `open()` return ELOOP instead. Creation mode 0600 keeps the log file user-only. Also collapses the two write branches into one. 3. CFSTRING LENGTH CAP IN getDeviceName `Audio.getDeviceName` now checks CFStringGetLength before bridging the CFString to Swift. If the length exceeds 256 UTF-16 units, we trim via `CFStringCreateWithSubstring` before the Swift String cast. Defends against a malicious third-party HAL plugin returning an arbitrarily large CFString — the bridge would otherwise pay a full copy on every device-list refresh (triggered by the HAL-device-list listener we added in R1). Real device names are a few tens of characters; 256 is a comfortable cap. --- MultiSoundChanger.xcodeproj/project.pbxproj | 4 +++ .../Other/MultiSoundChanger.entitlements | 17 +++++++++ .../Sources/Frameworks/Audio.swift | 14 +++++++- MultiSoundChanger/Sources/Utils/Logger.swift | 35 ++++++++++++++----- 4 files changed, 60 insertions(+), 10 deletions(-) create mode 100644 MultiSoundChanger/Other/MultiSoundChanger.entitlements diff --git a/MultiSoundChanger.xcodeproj/project.pbxproj b/MultiSoundChanger.xcodeproj/project.pbxproj index 58603a3..76ffe68 100644 --- a/MultiSoundChanger.xcodeproj/project.pbxproj +++ b/MultiSoundChanger.xcodeproj/project.pbxproj @@ -511,10 +511,12 @@ baseConfigurationReference = 6FD0ED04AFD1CC1242C9B3B3 /* Pods-MultiSoundChanger.debug.xcconfig */; buildSettings = { ASSETCATALOG_COMPILER_APPICON_NAME = AppIcon; + CODE_SIGN_ENTITLEMENTS = MultiSoundChanger/Other/MultiSoundChanger.entitlements; CODE_SIGN_IDENTITY = "-"; CODE_SIGN_STYLE = Manual; COMBINE_HIDPI_IMAGES = YES; DEVELOPMENT_TEAM = ""; + ENABLE_HARDENED_RUNTIME = YES; FRAMEWORK_SEARCH_PATHS = ( "$(inherited)", "$(PROJECT_DIR)", @@ -536,10 +538,12 @@ baseConfigurationReference = D184B2CD842B856AFFE7DF7E /* Pods-MultiSoundChanger.release.xcconfig */; buildSettings = { ASSETCATALOG_COMPILER_APPICON_NAME = AppIcon; + CODE_SIGN_ENTITLEMENTS = MultiSoundChanger/Other/MultiSoundChanger.entitlements; CODE_SIGN_IDENTITY = "-"; CODE_SIGN_STYLE = Manual; COMBINE_HIDPI_IMAGES = YES; DEVELOPMENT_TEAM = ""; + ENABLE_HARDENED_RUNTIME = YES; FRAMEWORK_SEARCH_PATHS = ( "$(inherited)", "$(PROJECT_DIR)", diff --git a/MultiSoundChanger/Other/MultiSoundChanger.entitlements b/MultiSoundChanger/Other/MultiSoundChanger.entitlements new file mode 100644 index 0000000..a791218 --- /dev/null +++ b/MultiSoundChanger/Other/MultiSoundChanger.entitlements @@ -0,0 +1,17 @@ + + + + + + + diff --git a/MultiSoundChanger/Sources/Frameworks/Audio.swift b/MultiSoundChanger/Sources/Frameworks/Audio.swift index 160ee86..45daea6 100644 --- a/MultiSoundChanger/Sources/Frameworks/Audio.swift +++ b/MultiSoundChanger/Sources/Frameworks/Audio.swift @@ -358,7 +358,19 @@ final class AudioImpl: Audio { return "" } - return name.takeRetainedValue() as String + let cfstr = name.takeRetainedValue() + // Cap the bridged Swift-String length at something far beyond any real device name + // (legitimate names are a few tens of chars; 256 UTF-16 units is extremely generous). + // A malicious third-party HAL plugin could otherwise return an arbitrarily large + // CFString here and force us to pay a large-bridge + large-Swift-String allocation on + // every device-list refresh. + let length = CFStringGetLength(cfstr) + let maxChars: CFIndex = 256 + if length > maxChars { + let truncated = CFStringCreateWithSubstring(kCFAllocatorDefault, cfstr, CFRange(location: 0, length: maxChars)) + return (truncated as String?) ??

The carefully-built errno/path text was being thrown away on every failure. Add `LocalizedError` conformance with an `errorDescription` that returns the underlying message. 2. Partial-write loop in `appendToFile` Single-shot `Darwin.write` silently dropped the tail on EINTR or short writes. Wrap it in a loop that advances by the returned byte count, retries EINTR, bails on write==0, and escalates any other errno. Surfaces the partial-progress count in the error message so a disk full / signal mid-flush situation is diagnosable instead of "mysterious log lines missing". 3. UTF-16 surrogate-pair trim in `getDeviceName` When capping at 256 UTF-16 units, byte 255/256 can land on a surrogate pair and leave a dangling high surrogate. `CFStringCreateWithSubstring` + bridge-to-Swift renders the orphan as U+FFFD. Back off by one unit if `CFStringGetCharacterAtIndex(cfstr, cut-1)` is a high surrogate (0xD800...0xDBFF). Cheap to check, avoids the replacement-character rendering in the unlikely case we ever hit the cap with a pathological device name. --- .../Sources/Frameworks/Audio.swift | 10 ++++- MultiSoundChanger/Sources/Utils/Logger.swift | 42 +++++++++++++++---- 2 files changed, 44 insertions(+), 8 deletions(-) diff --git a/MultiSoundChanger/Sources/Frameworks/Audio.swift b/MultiSoundChanger/Sources/Frameworks/Audio.swift index 45daea6..ed146f7 100644 --- a/MultiSoundChanger/Sources/Frameworks/Audio.swift +++ b/MultiSoundChanger/Sources/Frameworks/Audio.swift @@ -367,7 +367,15 @@ final class AudioImpl: Audio { let length = CFStringGetLength(cfstr) let maxChars: CFIndex = 256 if length > maxChars { - let truncated = CFStringCreateWithSubstring(kCFAllocatorDefault, cfstr, CFRange(location: 0, length: maxChars)) + // If the last UTF-16 unit at the cut point is a high surrogate (range + // 0xD800...0xDBFF), backing off by one avoids leaving a dangling lead surrogate + // that bridges to Swift as U+FFFD. + var cut = maxChars + let lastChar = CFStringGetCharacterAtIndex(cfstr, cut - 1) + if (0xD800...0xDBFF).contains(lastChar) { + cut -= 1 + } + let truncated = CFStringCreateWithSubstring(kCFAllocatorDefault, cfstr, CFRange(location: 0, length: cut)) return (truncated as String?) ??

We sign ad-hoc (CODE_SIGN_IDENTITY = "-"), and ad-hoc signatures have no team, so the embedded MediaKeyTap.framework (from CocoaPods' `use_frameworks!`) failed to load at launch time. Add `com.apple.security.cs.disable-library-validation`. This is the canonical Hardened-Runtime exception for source-built open-source macOS apps that embed third-party frameworks via CocoaPods/Carthage but don't sign with a Developer ID. Narrowly scoped: only affects which dylibs can load into this process. Real risk requires an attacker with write access to the .app bundle, at which point dylib injection is the least of the victim's concerns. Worth the trade for "archive+export actually runs". If the upstream maintainer later ships via Developer ID + notarization, this entitlement can be removed — the standard CocoaPods xcconfig will re-sign the embedded frameworks with the same team and library validation will pass again. --- .../Other/MultiSoundChanger.entitlements | 35 ++++++++++++++----- 1 file changed, 26 insertions(+), 9 deletions(-) diff --git a/MultiSoundChanger/Other/MultiSoundChanger.entitlements b/MultiSoundChanger/Other/MultiSoundChanger.entitlements index a791218..c203c4a 100644 --- a/MultiSoundChanger/Other/MultiSoundChanger.entitlements +++ b/MultiSoundChanger/Other/MultiSoundChanger.entitlements @@ -3,15 +3,32 @@ + com.apple.security.cs.disable-library-validation + From 792e3b0b4fdcec4bf78df95806be146f250b35d5 Mon Sep 17 00:00:00 2001 From: solartrans Date: Tue, 21 Apr 2026 03:52:06 -0700 Subject: [PATCH 48/48] Add hierarchical Claude context files; update entitlements narrative MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CLAUDE.md is now an orientation hub (≈200 lines).

Don't revert to the old raw `animator().alphaValue = 0` + `DispatchQueue.main.asyncAfter(0.3)` pattern — the two timelines could race and `orderOut` could land before the fade completed. + +`isReleasedWhenClosed = false` is deliberate — the window is reused across events, not closed.

If already on main (the volume-hotkey path always is), it calls `displayOSD` synchronously — skipping the runloop hop saves a visible frame between keypress and OSD appearance. If called from a non-main context, it falls back to `DispatchQueue.main.async`. All access to `osdWindow` happens on main after this branch, so no explicit lock is needed. + +### Positioning + +`repositionOn(screen:)` uses `screen.visibleFrame` (not `screen.frame`) so the OSD respects the menu bar and dock on the primary display.

If the menu is currently open, mutating NSMenu's items can crash AppKit's tracking machinery — so the method sets `pendingRefresh = true` and returns. `menuDidClose` drains the pending flag. This pattern exists because the alternative (always mutate, hope) used to crash on fast USB device hot-plug during an open menu. + +### Device-list reconstruction + +Device items are tracked in `deviceMenuItems: [NSMenuItem]` and anchored at `outputSectionAnchor: NSMenuItem?` (the disabled "Output Device:" label). `populateDeviceList(in:)`: + +- Sorts the devices dictionary by name (case-insensitive localized compare) — without this, dictionary iteration order is unspecified and the menu would reshuffle per launch. +- Inserts each device item at `anchorIndex + 1`. If the anchor is missing (shouldn't be, but defensive), logs a warning and returns — better to have a stale menu than items appended after the Quit item. + +### `selectDevice(device:)` vs `adoptDevice(_:)` (mirrors AudioManager) + +- `selectDevice` is used by `menuItemAction` (user clicked a row in the device menu). Propagates to the system default. +- `adoptDevice` is used by `populateDeviceList` (startup match to system default) and `syncDefaultOutputDevice` (external default-change notification). Does NOT propagate — would cause a listener loop. + +Both share `refreshUIForSelectedDevice()` which pulls the current volume, applies mute correction, and updates the slider + status-bar icon. + +### Status-bar icon bucketing + +`changeStatusItemImage(value:)` maps 0–100 → one of four icons at thresholds `<=1`, `<=33.33`, `<=66.66`, `else`. The `<=1` edge case is deliberate — `value == 1` (exactly 1%) used to fall into no bucket in the old `< 1 / > 1` form, leaving the icon stale. `100 / 3 * 2` evaluates to `(100/3)*2 ≈ 66.66`. Do not "correct" to `100/(3*2) = 16.67` — that would be wrong. + +## Logger + +`MultiSoundChanger/Sources/Utils/Logger.swift`. + +### File write path + +`Logger.debug/info/warning/error` → `outAndFilePrint(symbol:string:)`: + +1. **Synchronously** `print()` to stdout on the caller's thread (cheap). +2. **Async** on `fileWriteQueue` (serial background) → `filePrint` → `appendToFile`. + +Main thread is never blocked on FileManager or FileHandle syscalls. Before this refactor, every volume-hotkey press synchronously wrote to disk from `ApplicationControllerImp.onMediaKeyTap`, stuttering rapid key-repeat. + +### POSIX write with `O_NOFOLLOW` + +`appendToFile(url:content:)` opens via raw `Darwin.open(path, O_WRONLY|O_APPEND|O_CREAT|O_NOFOLLOW, 0o600)` — not `FileHandle(forWritingTo:)`. The reason is symlink defense: a local attacker planting a symlink at `~/Library/Caches//app.log` pointing to e.g. `~/.ssh/id_rsa` would otherwise cause our append to flow through the symlink and corrupt the target. `O_NOFOLLOW` makes `open()` return `ELOOP` if the final path component is a symlink. + +Creation mode `0o600` keeps the log file user-only regardless of the process's umask. + +`defer { Darwin.close(fd) }` on every success path — `write` errors don't leak the descriptor. + +### Write loop + +`Darwin.write` can return fewer bytes than requested on `EINTR`, signal interruption, or disk pressure. The loop: + +- Advances `offset` by the returned count on success. +- `continue`s on `errno == EINTR`. +- Breaks on `written == 0` (unusual but not strictly an error; abort). +- Escalates other errno values to a thrown `LoggerError.fileError(...)`. + +### `LoggerError` conforms to `LocalizedError` + +`filePrint` catches errors and surfaces them via `error.localizedDescription`. Without `LocalizedError` conformance, `localizedDescription` returns Cocoa's generic `"The operation couldn't be completed."` wrapper — and our carefully-constructed `"open(/path) failed: (errno=N)"` telemetry is replaced with a useless string. `errorDescription` on the enum returns the actual message. + +### `isLogFileRemoved` serialization + +Declared `private static var`. Access is NOT lock-guarded, **and that's fine** — every read/write happens inside the `fileWriteQueue.async` block, and that queue is serial (DispatchQueue with no attributes). This has been flagged as a race in multiple audits; each time the answer is "trace the call sites, they're all on the serial queue". The comment above the declaration spells this out. + +### `DateFormatter` cached + +`logDateFormatter: DateFormatter` is a `static let`, constructed once and reused. DateFormatter construction is orders of magnitude more expensive than `.string(from:)`; per-log-call construction was measurable.

Don't rearrange. + +`ApplicationControllerImp` conforms to both `MediaManagerDelegate` (for `onMediaKeyTap`) and `AudioManagerDelegate` (for `audioManagerDidChangeDevices` / `audioManagerDidChangeDefaultOutputDevice`).

The same handful of patterns got flagged over and over — each was triaged, confirmed intentional, and the rationale captured here so future audits (and future Claude sessions) don't re-raise them. + +If a static analyzer, LSP, or audit agent flags something listed here, **it's not a bug**. The fix is already in place or the code is intentionally shaped this way. + +## Code patterns + +### 1. `AudioManagerImpl.readDeviceVolumeFromHAL` returns `nil` on an aggregate with no output sub-device + +**Flagged as**: "silent failure", "nil return breaks volume display". + +**Reality**: Documented design. See `docs/ARCHITECTURE.md` § aggregate devices. An aggregate legitimately has no volume to read if none of its sub-devices are outputs — returning `nil` is honest. Callers (`getSelectedDeviceVolume`, `toggleMute`'s unmute-restore check) handle nil correctly. + +### 2. `StatusBarController.changeStatusItemImage` thresholds `100 / 3 * 2` + +**Flagged as**: "operator precedence bug; should be `100 / (3 * 2) = 16.67`." + +**Reality**: The code is intentional. `100 / 3 * 2 = (100/3) * 2 ≈ 66.66` is the upper-third threshold for mapping volume → icon (four icons, three boundaries at 0, 33.33, 66.66, 100). The other way around would be nonsensical. + +### 3. `[Float].max()` returning `Float?` + +**Flagged as**: "nil-safety violation", "force-unwrap risk". + +**Reality**: Correct by design. `Array.max()` returns `Element?` because an empty array has no max. `getDeviceVolume` returns a 3-element array `[master, left, right]`, so `.max()` never nil in practice, but the optional signature is Swift's stdlib behavior. + +### 4. `Constants.chicletsCount = 16` "division by zero risk" + +**Flagged as**: "if chicletsCount is 0, `1 / Float(Constants.chicletsCount)` crashes". + +**Reality**: It's a compile-time constant literal `16`. It can't be 0 unless someone edits `Constants.swift` to make it 0. Not a runtime risk. + +### 5. `CFStringCreateWithSubstring` in `Audio.getDeviceName` + +**Flagged as**: "leaks the retained CFString; needs `takeRetainedValue()` or `CFRelease`". + +**Reality**: `CFStringCreateWithSubstring` is annotated `CF_RETURNS_RETAINED` in CoreFoundation, and Swift's CF bridge imports it as a Swift-ARC-managed `CFString?`. It is NOT an `Unmanaged?`. The local `truncated` var goes through standard Swift retain/release at function exit. No leak. + +### 6. HAL listener `onChange` strong capture + +**Flagged as**: "retain cycle — block captures onChange strongly". + +**Reality**: The block DOES capture `onChange` strongly, on purpose. `onChange` is what the caller passed in, and at the call site it's `{ [weak self] in self?.handleDevicesChanged() }` — so `onChange` weakly references `self`. If `self` deallocates, the closure body becomes a no-op. No cycle. + +### 7. `DispatchQueue.main.async` in the HAL listener block + +**Flagged as**: "redundant main-hop; should call `onChange` directly." + +**Reality**: The HAL listener fires on a dedicated background serial queue (`listenerQueue`). Every subsequent handler touches NSMenu / NSStatusItem / UI state, which must be on main. The hop is mandatory. + +### 8. `OSDWindow` mutation / `osdWindow` thread safety + +**Flagged as**: "race condition on `osdWindow` / `fadeTimer`". + +**Reality**: `OSDManager.showImage` branches on `Thread.isMainThread`. If on main, calls `displayOSD` synchronously; if off main, hops to main via `async`. Either way, `displayOSD` and all mutations of `osdWindow` / `fadeTimer` run exclusively on main. No concurrent access. + +### 9. `Logger.isLogFileRemoved` "race condition" + +**Flagged as**: "static mutable flag without a lock". + +**Reality**: All reads/writes of `isLogFileRemoved` happen inside `fileWriteQueue.async { try filePrint(…) } → removeLogFileIfNeeded`. `fileWriteQueue` is a `DispatchQueue(label:)` with no attributes — serial by default. A serial queue serializes every block it runs, so access is trivially sequenced. The comment at the declaration spells this out. + +### 10. `IBOutlet weak var foo: NSSlider!` "force unwrap" + +**Flagged as**: "force_unwrapping SwiftLint violation". + +**Reality**: The `!` is an implicitly-unwrapped-optional declaration, standard Swift idiom for storyboard-wired outlets. SwiftLint's `force_unwrapping` rule targets uses like `someOptional!`, not IUO declarations. + +### 11. `case empty = ""` "empty_string violation" + +**Flagged as**: "`Constants.Keys.empty = ""` violates `empty_string` rule." + +**Reality**: SwiftLint's `empty_string` rule targets `String()` initializer calls and `== ""` comparisons, not enum raw-value literals. The enum case's raw value is a compile-time constant string; there's nothing to flag. + +### 12. OSD y-position `screen.visibleFrame.midY + height/4` + +**Flagged as**: "sign error; should be `- height/4` for lower-half placement". + +**Reality**: Intentionally upper-center. `midY + height/4` places the OSD ~25% above the vertical center, matching where the original `OSD.framework` drew. Lower-half placement would conflict with the dock and Command-Tab UI area. + +### 13. `printDevices()` / `sanitizedForLog(_:)` in AudioManager "dead code" + +**Flagged as**: "never called / serves no purpose". + +**Reality**: `printDevices()` is called from `AudioManagerImpl.init()` (startup device enumeration for log). `sanitizedForLog` is called from `printDevices`. Both are live. The "only logs debug output" dismissal is wrong — logging IS the purpose. + +### 14. Partial write in `Logger.appendToFile` + +**Flagged as**: "single `Darwin.write` without a loop drops tail bytes on EINTR". + +**Reality**: There IS a loop — lines inside `data.withUnsafeBytes { buffer -> String? in var offset = 0; while offset < buffer.count { … } }`. It retries `EINTR`, bails on `write == 0`, escalates other errno values. Don't re-flag based on a skim. + +### 15. `VolumeViewController` "slider unit mismatch" + +**Flagged as**: "passes 0…100 UI value to HAL's 0…1 expected range". + +**Reality**: The code does `audioManager?.setSelectedDeviceVolume(volume: sliderValue / 100)`. Divides by 100. Read it. + +### 16. Ad-hoc code signing "security issue" + +**Flagged as**: "CODE_SIGN_IDENTITY = '-' is insecure for distribution". + +**Reality**: True for distribution, false for local dev / source-built use. For shipping, switch to Developer ID — see `docs/BUILD_AND_SIGNING.md`. The app is open-source and the maintainer doesn't distribute binaries themselves; ad-hoc is the right posture here. Don't flag this as if it's a blocking issue. + +### 17. `com.apple.security.cs.disable-library-validation` in entitlements "weakens security" + +**Flagged as**: "Hardened Runtime exception — violates principle of least privilege". + +**Reality**: Required for ad-hoc-signed apps with embedded CocoaPods frameworks. Without it, `Product → Archive → Export → double-click` fails to launch because library validation rejects the embedded MediaKeyTap.framework (ad-hoc signatures have no team identity to match). Narrow scope — affects which dylibs can load into this process only. Real risk requires write access to the .app bundle, which strictly subsumes dylib injection. Remove only when shipping via Developer ID + notarization, which makes the library validation work without exception. + +### 18. "`xcuserdata/` has `DynamicsIllusion.xcscheme`" + +**Flagged as**: "stale schema from pre-fork project". + +**Reality**: `xcuserdata/` is user-specific Xcode state, not part of the project definition. Those schemes belong to whoever originally created the repo's Xcode state; they don't affect builds on other machines. The tracked `project.pbxproj` and `.xcscheme` files under `xcshareddata/` are the authoritative version. Don't delete `xcuserdata/` content as a "fix". + +### 19. `@NSApplicationMain` "deprecated in Swift 5.3+" + +**Flagged as**: "should be `@main`". + +**Reality**: We tried `@main` once and it broke the build. `@main` requires the type itself to provide a `static func main()`; `@NSApplicationMain` emits an auto-generated `main()` that calls `NSApplicationMain()` which loads the Main storyboard. Our app relies on the storyboard loader, so we need `@NSApplicationMain`. Apple still supports it on macOS; the deprecation is a style warning at most. + +## Tool caveats + +### SourceKit single-file mode lies + +The editor's LSP (SourceKit-LSP) runs in single-file parse mode without the full module graph.

CocoaPods' standard xcconfig re-signs embedded frameworks with the same team as the main binary during a Developer ID build, so library validation passes naturally. + +## Code signing + +`CODE_SIGN_IDENTITY = "-"` is ad-hoc signing — appropriate for local development but not distributable. For distribution: + +1. Set `CODE_SIGN_IDENTITY` to `"Developer ID Application"` (for direct distribution outside the App Store) on the Release config. +2. Set `DEVELOPMENT_TEAM` to the team ID. +3. Build the Release scheme: `xcodebuild -workspace MultiSoundChanger.xcworkspace -scheme MultiSoundChanger -configuration Release archive -archivePath build/MultiSoundChanger.xcarchive`. +4. Export as a Developer ID app: `xcodebuild -exportArchive -archivePath build/MultiSoundChanger.xcarchive -exportPath build/MultiSoundChanger-release -exportOptionsPlist ExportOptions.plist`. +5. Notarize: `xcrun notarytool submit build/MultiSoundChanger.app.zip --apple-id <...> --team-id <...> --password --wait`. +6.

Rules of thumb: + +- **For the main `MultiSoundChanger` project**: safe to click Perform Changes. Those edits land in the tracked `project.pbxproj` and can be reviewed as a git diff. Exception: `Enable User Script Sandboxing` may break the SwiftLint build phase — if SwiftLint stops running after applying, disable the phase's "Based on dependency analysis" toggle (which is also how we fixed the "run during every build" warning). +- **For the `Pods` project**: do NOT click Perform Changes. Those edits land in `Pods.xcodeproj` which CocoaPods regenerates on next `pod install`, wiping the changes. Add the equivalent build settings to `Podfile`'s `post_install` hook instead (see above). + +## SwiftLint phase + +In `project.pbxproj` the SwiftLint `PBXShellScriptBuildPhase` has `alwaysOutOfDate = 1;` set — equivalent to unticking "Based on dependency analysis" in the Build Phase inspector.
