I'm trying to make a simple swipe up gesture, I dragged the Swipe Gesture Recogniser over a UIImage, I then Ctrl button drag the Swipe Gesture to my swift file and create the following Action: -

```
@IBAction func swipeDice(sender: UISwipeGestureRecognizer) {
    //Test display
    testLabel.text = "Zing"
}

```

The app builds and runs successfully however when I test the swipe gesture it doesn't seem to do anything.

Is that all the code I need for the gesture to run?
How do I make it recognise a 2 finger swipe gesture?
