Cannot build for iOS Simulator on Apple Silicon

[Drarok]

I think the issue stems from this line. Someone else has come to the same conclusion.

The builds produced cannot be run on the iOS Simulator on Apple Silicon, failing with the error:

Could not find module 'Mapper' for target 'arm64-apple-ios-simulator'; found: x86_64-apple-ios-simulator, i386-apple-ios-simulator, at: /Users/…/Library/Developer/Xcode/DerivedData/…/Build/Products/Debug-iphonesimulator/Mapper.framework/Modules/Mapper.swiftmodule
