This is a known bug in Xcode 13 (79090498) that will hopefully be fixed by Apple soon. In the meantime you can't deploy code built with Xcode 13 to OS versions earlier than iOS 15.

Apps that contain Swift code referencing featureIdentifier or typeIdentifier fail to launch on earlier OS releases. (79090498)

If you find another workaround, please let us know!
