It seems like you're asking about a specific term "UIDesignRequiresCompatibility," which doesn't directly appear in the provided context. However, I can provide information related to design compatibility and adaptability in UIKit apps as discussed in the WWDC sessions.
In the session titled "Make your UIKit app more flexible," it is mentioned that the "UI requires fullscreen" info.plist key is a compatibility mode from iOS 9 that prevents scene resizing. This key is deprecated and will be ignored in future releases. Apps that are adaptable do not need this key and should remove it. This is part of ensuring that your app is flexible and can adapt to different screen sizes and orientations. For more details, you can refer to the Make your UIKit app more flexible session.
If you have more specific questions about design compatibility or need further details on a related topic, feel free to ask!
