title: My Nav Controller not seeing in simulator even when I deleted main storyboard
body: <p>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.</p>
  <p>And coded this code in SceneDelegate. What's the problem</p>
  <pre><code> guard let windowScene = (scene as? UIWindowScene) else { return }
          window = UIWindow(windowScene: windowScene)
          window?.rootViewController = UINavigationController(rootViewController: ToduhListViewController())
          window?.makeKeyAndVisible()
  </code></pre>
