I've created a new xcode project in Xcode 11, I've removed the scene delegate from the info plist and replaced the app delegate methods with some from Xcode 10 .When I run the project in the iOS 13 simulator the app work completly fine, but when I run it on an older iPhone on iOS 12.4 the app crashes and I get this in the log
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UINavigationBar 0x143d13aa0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key ibShadowedLargeTitleTextAttributes.'

libc++abi.dylib: terminating with uncaught exception of type NSException
How should I solve this ?
