Component - Deep linking

This UI component demonstrates how an iOS app handles deep linking. Deep linking lets users open the app directly to a specific screen or content by tapping a special link, like opening a message or product page right away.

Widget Tree
AppDelegate
└── UIWindow
    └── UINavigationController
        └── UIViewController (Home Screen)
            └── UILabel (Welcome Text)
            └── UIButton (Open Deep Link)
The app starts with AppDelegate managing the window. The window shows a navigation controller that manages screen navigation. The home screen is a view controller with a welcome label and a button to simulate opening a deep link.
