I have a fair amount of legacy UIKit code since I support iPadOS as well. Is there a way around that? The app started out as UIKIt and I am progressively moving it over to SWiftUI as it supports more features.

In my case, this started happening for iOS simulators when I moved from an Intel Mac to an M series Mac. I had the following line in my xconfig: EXCLUDED_ARCHS[sdk=iphonesimulator*] = arm64 Removing that seems to fix the problem.
