[App.framework] Linked and embedded framework 'App.framework' was built for iOS/iOS Simulator #50568
Description
Activity
As an update, just finished reinstalling the stable release of Xcode and using
xcode-selectto set it back to 11.3.1, and it works as expected. Launches in all emulators.Something must have broken in 11.4 beta.
I'm also on Xcode 11.4 beta and I just created a new app and was able to
flutter run -d <simulator>without build errors on Flutter 1.12.13+hotfix.7.- Did you run
sudo xcodebuild -runFirstLaunchafter youxcode-selectto Xcode 11.4? - Are you able to run on that simulator from
ios/Runner.xcworkspacein Xcode?
- Did you run
Hi @jmagman, thanks for responding. Yes, I did do the first run and I have tried running through Xcode as well and it is throwing me the same error.
Let it be noted that it can build for generic iOS devices, and can run on physical devices, but is only showing this error on simulators.
With both Xcode's installed together, I can use the beta (11.4) simulator with stable Xcode (11.3.1) and it works correctly. So it must be something in Xcode 11.4 that is causing the issue.
I briefly saw this error, and I'm not sure how to I got into or out of that state.
It's failing to even start the build to get to the script that would assemble the right variant. We could swap App.framework to App.xcframework but that would be a nightmare of a project file migration...

iosfolder, which effectively deleted App.framework since it's in the .gitignore, and it seems to be working now! Works from both Xcode 11.4 andflutter run -d <id>.Glad you have a workaround, but this is concerning so I'm going to reopen until we understand how often this is happening.
Can you let us know if you see it again, and how you got in that state?
I had another machine that had a copy of the project on it. Using the
App.frameworkfrom that project causes the issue to reappear. I have attached an archive that contains both a working and non-working copy of App.framework. I hope that can help you with the debugging!If there are any other files you may want please let me know!
With the rebuilt
App.frameworkI am not longer able to launch on my physical device. I now get this:
It appears that the first build of
App.frameworkcauses it to only be compatible with the device type (simulator or physical) that is being used for that run.Deleting
App.frameworkwill cause it to be rebuilt on the next run and it will work correctly until you switch device types again. Running justflutter cleanisn't enough, but you'll have to run it when you deleteApp.frameworkotherwise it will try to install the cached build.Again this only occurs with Xcode 11.4/Simulator 11.4. I did a build for physical devices which created an
App.framework. Attempted to launch with Simulator 11.4 running an iOS 13.4 image and it failed to launch. I switched the command line tools back to Xcode 11.3/Simulator 11.3, and without changingApp.frameworkit still works.Reacted by Emre Besirik and Paulo Dias27 remaining items

Particularly the build phase:
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin@jmagman Thanks for this.

This appears to have started since upgrading to Catalina 10.15.4 beta with Xcode 13.4 beta, which also updated Simulator to 13.4 (921.4).
The application compiles and runs correctly on a physically attached device, but no simulators of any devices can pass this stage.
EDIT: Just attempted both Flutter beta and dev channels, and the same error occurs after rebuilding the tools and running
flutter cleanin the project root.
