+1 on this. Under Catalina/Xcode 12/iOS 14, bluepill won't even come up.

bluepill --xctestrun-path /Users/vn50v8w/Library/Developer/Xcode/DerivedData/XXX-gvsecbrvsntufqalpwmusjzuwuns/Build/Products/XXX_AppSharedDefault_iphonesimulator14.1-x86_64.xctestrun \
-o ./bluepill-build/ \
-n 6 \
-L  \
-r  'iOS 14.1' \
--unsafe-skip-xcode-version-check \
-a /Users/vn50v8w/Library/Developer/Xcode/DerivedData/XXX-gvsecbrvsntufqalpwmusjzuwuns/Build/Products/Debug-iphonesimulator/XXX.app

yields...

Somewhere we changed test info from an array to a dict. Worth investigating.

ravimandala commented 3 years ago

Looking into this.

ob commented 3 years ago

@mcstoufer can you share the XXX_AppSharedDefault_iphonesimulator14.1-x86_64.xctestrun file?

carlocab commented 3 years ago

FYI, I think the lack of Xcode 12.2 support is keeping Bluepill 5.4.2 from being upgraded on Homebrew: https://github.com/Homebrew/homebrew-core/pull/66592

chenxiao0228 commented 3 years ago

@carlocab the homebrew-core issue seems different from this one.

@mcstoufer it seems Bluepill wants a dictionary from the xctestrun file for a field but instead it got a NSArray. Like @ob mentioned would you be able to share the xctestrun file so we can find the root cause?

carlocab commented 3 years ago

@chenxiao0228 I don't see the difference, I'm afraid. Do you mind elaborating a little?

ob commented 3 years ago

I think what @chenxiao0228 means is that the error in the Homebrew CI run is:

error: The linked framework 'CoreSimulator.framework' is missing one or more architectures required by this target: arm64. (in target 'bp' from project 'bp')
error: The linked framework 'CoreSimulator.framework' is missing one or more architectures required by this target: arm64. (in target 'bplib' from project 'bp')

which sounds like the Simulators installed on that machine have been stripped of the arm64 target architecture (which is what real iPhones use). We can work around that here by making sure we only build for x86_64 since we are only targeting the Simulators, although with the new M1 based machines it's unclear how this will work out...

carlocab commented 3 years ago

@ob Thank you for the explanation. It seems like this

We can work around that here by making sure we only build for x86_64

might help fix the build failure over at Homebrew. I'm not too familiar with bluepill; if you have a quick explanation of how to do this I'd appreciate it. Otherwise, I'll try to figure it out.

chenxiao0228 commented 3 years ago

I have skipped 12.2 and looking at 12.3 now. There are several issues I have found so far. Xcode 12.3 builds for Apple Silicon arm64 but CoreSimulator only has arm64e slice. We will have to disable the arm64 target. Then I also saw some issues with nm. Will get to it soon.

chenxiao0228 commented 3 years ago

Fixed in v5.6.0

carlocab commented 3 years ago

5.6.0 seems to have also fixed the Homebrew build. Thanks!
