Custom entry point to app without storyboard initial point Navigate from app delegate swift

 Solution:

In scene delegate class change the code like below

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

        guard let windowScene = (scene as? UIWindowScene) else { return }

        let window = UIWindow(windowScene: windowScene)

        let storyboard = UIStoryboard(name: "Main", bundle: nil)

        let initialViewController = storyboard.instantiateViewController(withIdentifier: "MyVC")

        window.rootViewController = initialViewController

        self.window = window

        window.makeKeyAndVisible()

    }

Also remove the entry point from storyboard like one viewcontroller is to be in initialviewcontroller remove that and also goto target and select build settings inside that remove the main in storyboard as like below

Then run the app it will works as per your requirement..Happy coding..
