Kotlin multiplatform mobile - fail to run iOS project - missing one or more architectures required by this target

Question

I create KMM(Kotlin multiplatform mobile) project using Android studio 4.1 RC3 and try to run the iOS App (with default code) but stuck with following error:

error: The linked and embedded framework 'shared.framework' is missing one or more architectures required by this target: arm64. (in target 'iosApp' from project 'iosApp')

But when I just hit 'build', it get built successfully. Only happening only when hit 'run' from Android studio. Mean while I used Xcode to run the same project and face no issues getting it deployed into the simulator successfully.

By the way I was following this official KMM guide https://kotlinlang.org/docs/mobile/create-first-app.html

Using Xcode 14 ( I tried simulators with iOS14,13.5,12.1) using Mac OS Catalina 10.15.6

Answer 1

This problem is most probably caused by Xcode 12 adding new simulator architectures. As a workaround, one can try adding arm64 to the Disable Architectures list in Build Settings . See the related issue here
