The iOS simulator builds only include x86_64 binaries. When attempting to run iOS apps in the simulator on M1 hardware, the Xcode project will fail because $(ARCHS_STANDARD_64_BIT) evaluates as arm64, rather than x86_64.
It is possible to work around this by manually setting VALID_ARCHS to x86_64; however, this means the iOS app is running as an Intel app.
To Reproduce
Steps to reproduce the behavior:
Generate an iOS HelloWorld app on M1 hardware
Run the app in an iOS simulator using Briefcase; note that the process is of type Intel in the Activity Monitor
Try to run the app by launching in Xcode; it will fail to build.
Expected behavior
When run using Briefcase, the app should present as Apple in the Activity Monitor.
The Xcode project should build without modifications
