Our app uses UIRequiresFullScreen=YES and runs on iPhones and iPads and we've rebuilt it using XCode 13.2.1 with SDK 15.2 as per Apple's instructions - https://developer.apple.com/news/?id=oefg5bhp
However our app still doesn't appear full screen on the iPad mini 6, it has black bars and in the debugger we can see that the window frame is 1024x768.
Is there something else not mentioned in Apple's instructions above that we need to set?
It might be worth re-creating a new nib file, using Xcode 13?
Did you manage to get this working? I am having a similar problem where my project is reporting the wrong resolution but a stub project I created is reporting the correct resolution.
I had a project that did not have a launch screen (storyboard) or main storyboard and it was reporting 1024x768 on the new mini. When I added a storyboard and launch screen to the project, it started reporting the correct resolution. You might want see if your case is similar.
