func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // 1. Capture the scene
    guard let windowScene = (scene as? UIWindowScene) else { return }
    
    // 2. Create a new UIWindow and pass in a UIWindowScene
    let window = UIWindow(windowScene: windowScene)
    
    // 3. Create a view hierarchy programmatically
    let rootVC = ViewController()
    let navController = UINavigationController(rootViewController: rootVC)
    
    // 4. Set the navigation controller as the window's root view controller
    window.rootViewController = navController
    
    // 5. Set the window and call makeKeyAndVisible()
    self.window = window
    window.makeKeyAndVisible()
