/// Example adding it the first time
let recognizer = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))

/// Test if gesture already added, if added return else add the recognizer
guard containsGestureRecognizer(recognizers: view.gestureRecognizers, find: recognizer) == false else { return }
/// Add the recognizer
view.addGestureRecognizer(recognizer)
