iOS: improve 'certificate error' log output

[m1ga]

I was building a store version of my app and at the end I've received this error message:

[ERROR] ** ARCHIVE FAILED **

The solution was to regenerated the certificates and I was able to build again. Since that error appeared quite often for other users on Slack it would be good to show a real error message if it is possible.

E.g. if you are missing the private key it will show the same error but when you look with trace it has more infos:

but info still shows the Requested but did not find extension.. stuff.

I've encountered this problem in two different situations in the last period, probably after xcode updates and I'm not sure if node also incremented a minor version.
In the first case, on the local folder, I had the problem related to the extension, there was no way to solve it except by deleting the whole project and re-downloading it from the repository.
In the second case, however, the final error was reported on the ti.documentpicker module. The solution was to remove the app from the samba volume and put it on the local drive.
I don't exclude that it could be some sort of xcode version problem, I exclude that they are problems introduced by me on projects that are managed in a completely different way.

According to https://stackoverflow.com/questions/71320584/flutter-build-ios-got-error-requested-but-did-not-find-extension-point-with-ide flutter users got the same errors with Xcode 13.3 & 13.4. Xcode 14 should fixed the issue.
@m1ga Did you get the errors again with Xcode 14, 15 or 16?

[m1ga]

@hbugdoll the issue was about the error information. E.g. in the trace log (screenshot) you can see that the private key was missing but the normal build error will always show that list of simluators and not the real error message. So it would help the users more to show that error not the list of simulators. I'm pretty sure the output with newer Xcode version is the same

@hbugdoll ... but the normal build error will always show that list of simluators and not the real error message.

Ah, now I understand your "optimize" in the topic.

[m1ga]

I've adjusted the title :-)

Some thoughts:

normal build error will always show that list of simluators and not the real error message

The challenge is probably that xcodebuild prints all in this case --- xcodebuild: WARNING: ... plus following lines (here the list of simulators) to stderr.
Detecting the start of such a warning would be easy, but where is the end?

in the trace log (screenshot) you can see that the private key was missing

I suspect the error: Missing private key for signing certificate comes not from xcodebuild itself, but from an underlying tool which prints always is incorrectly printed to stdout.

[hbugdoll]

I played around a bit and got the --- xcodebuild: WARNING plus simulator list on stdout and therefore at trace level.

...
[TRACE] IDEPackageSupportUseBuiltinSCM = YES
[TRACE] UseNewBuildSystem = YES

It seems that the previous log output (whether was an error or not) has an influence on this...
