If you don't want to use main storyboard, if you want to create you own views programmatically.

For xcode 11.

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

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

This will defenetily work. Thanks
