“Unrecognized selector sent to instance” in swift

Question

I have no idea what I am doing wrong. I am also quite new to programming so I am not very good at debugging. This was a test app so that I can see how swift ties in with app

Answer 1

In your viewDidLoad, notice my Selector is calling my func with the colon.

override func viewDidLoad() {
        super.viewDidLoad()
        // init gesture recognizer swipe right vars
        var rightSwipe = UISwipeGestureRecognizer(target: self, action: Selector("gestureFunc:"))
        rightSwipe.direction = UISwipeGestureRecognizerDirection.Right
        view.addGestureRecognizer(rightSwipe) 
    }

Then make sure that the Selector i.e. func is ready to receive it's swipe:

        // selector from UISwipeGestureRecognizer
        func nextWeapon(gesture: UISwipeGestureRecognizer) {
        println("swipe right")
        }
