When an iPad app's screen change from full screen mode to split view mode no app delegate methods called. applicationWillResignActive and applicationDidBecomeActive does not get called. Same case for UIWindowSceneDelegate methods. SceneDidBecomeActive and SceneWillResignActive does not get called. Tested via Xcode 11.1 and on Xcode 11.2 beta version.
Testing is done for projects which does not support multiple window scene on iPad.
For example:
1. Open Xcode 11.2 Beta build.
2. Create a new document based iOS project.
3. Run the app on an iPad simulator.
4. On iPad simulator bring the app from full screen mode to half screen mode (split view mode) ----> No Appdelegate methods get called.
