I am getting a new error on my M1 when trying to run my shared library on iOS Simulator Arm64 (not an issue when running on a physical device). The command CompileSwift fails with:

<unknown>:0: error: unable to load standard library for target 'arm64-apple-ios10.0'

I’ve tried everything suggested online, clean derived data, restart xcode, clear environment, download ios 10 simulators (there are none). I strongly suspect it’s related to errors I had earlier compiling the shared KMM framework: https://kotlinlang.slack.com/archives/C3PQML5NU/p1654109309669219

Does anyone know why this might be happening? Its pretty ambiguous and nothing online has helped so far. This seems to be a problem with the simulator target only.

Can you show us your gradle file ?

Any ideas? I see other threads about the XCTestFramework path but would like to get unblocked without changing our build process for the time being.

[Louis Gautier]

Your simulator is an iOS 10 ? But yout pod file specify a minimum of 12. I have no other clue. Sorry

[Rachel Carandang]

Thanks for your help so far anyway! The simulator 10 issue I have no idea since it’s not on my machine that I know of 🤦‍♀️
