My Nav Controller not seeing in simulator even when I deleted main storyboard

I deleted my main storyboard and I just want to begin with my ToDuhListViewController with NavigationController but NavController not showing. I just deleted main in info.plist and general settings.

And coded this code in SceneDelegate. What's the problem

 guard let windowScene = (scene as? UIWindowScene) else { return }
        window = UIWindow(windowScene: windowScene)
        window?.rootViewController = UINavigationController(rootViewController: ToduhListViewController())
        window?.makeKeyAndVisible()
