I'll just post this into the ether while I spend the rest of my day trying to figure it out. Maybe someone out there has some insight?
On iOS 26.3.1 (not any major OS prior) if I add a UITableView to the UIWindow of a UIWindowScene of a UIScreen which is an external screen (😮‍💨) UIKit crashes with a fatal error about a missing user idiom.. Woot. No crash if I add a plain UIView. iOS 26 bug? What to do?
#UIKit #Xcode #iOSDev
@2ndNatureDev yep your app delegate isn't returning the correct external display type of screen configuration, you're returning 'windowedApplication' instead of what it requests
@stroughtonsmith You're amazing, thank you!
