Unbalanced calls to begin/end appearance transitions for

Question

I read SO about another user encountering similar error, but this error is in different case.

I received this message when I added a View Controller initially:

Answer 1

Swift 5

 func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {


//Delete or comment the below lines on your SceneDelegate.

//        guard let windowScene = (scene as? UIWindowScene) else { return }
//        window?.windowScene = windowScene
//        window?.makeKeyAndVisible()

        let viewController = ListVC()
        let navViewController = UINavigationController(rootViewController: viewController)
        window?.rootViewController = navViewController

    }
