Hey, Mike.
Sorry to hear you’re running into this issue. Have you read the Xcode 12 and Universal Screen Size Support aside. It reads:
At the time of this writing, it looks as if some key settings that enable universal support are not set when using Xcode 12. If you’re using Xcode 12, you’ll need to add a plist entry for
Launch screen interface file base name. You can either add this entry and set its value toMainor create a customLaunchScreen.storyboardfile and set its value toLaunchScreeninstead.
I’m not sure if that’s what you’re running into, but that could be the problem, Let me know if this helps!
