I've faced the same issue. If I launch Xcode using rosetta it doesn't show anything, but once I switch off rosetta and it works perfect.

I've faced the same issue. Do you use Swift Package Manager? Due to the Xcode bug, libraries have a binary target cause a "code signature found" error. For example, Firebase has same issue. https://github.com/firebase/firebase-ios-sdk/issues/6472 I've stop to use Swift Package Manage for binary frameworks and reverted to use CocoaPod for a while.
