iOS 14
- remove main story board from files
- from => info remove 'main storyboard file base name'
- then drill down in scene manifest to remove main item 0 main file name and remove
adjust code in sceneDelegate:
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let windowScene = (scene as? UIWindowScene) else { return }
let window = UIWindow(windowScene: windowScene)
window.rootViewController = ViewController()
window.makeKeyAndVisible()
self.window = window
}
...

Not in appDelegate anymore...
in SceneDelegate:

// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
