Through this question I would like to know if I understand well the notion of Root View Controller. In iOS application, the Root View Controller (RVC) is the controller whose view gets added to the UIWindow application at startup, isn't true? [window addSubview:rvcController.View]; [window makeKeyAndVisible]; Now, an UIWindow has also a rootViewController property. When running the previous snippet of code, does that property gets populated with the rvcController or do I have to set it explicitly? Then, in a UINavigationController it is possible to set a RVC that is different from the previous

Im trying to swap to another root view controller with a tab bar; via app delegate, and I want to add transition animation. By default it would only show the view without any animation. let tabBar = self.instantiateViewController(storyBoard: "Main", viewControllerID: "MainTabbar") let appDelegate = UIApplication.shared.delegate as! AppDelegate appDelegate.window = UIWindow(frame: UIScreen.main.bounds) appDelegate.window?.rootViewController = tabBar appDelegate.window?.makeKeyAndVisible() That's how I swapped to another rootview controller. I evaluated UIView.transition(from: view, to: view)
