If the app is not in the background, I can check launc

UIApplication.State did not work for me, because once I read fingerprint (modal is shown) in my app, notification is also thrown in upper bar and user must click it.

I've created

public static var isNotificationFromApp: Bool = false

in AppDelegate and I set it true in my starting viewController and then in my notification storyboard/viewControllerI just check that :)

Hope it can come in handy
