How can I get a new 'fun fact' when I swipe?

I built fun facts to work using the button to trigger a new fact as shown in the course.

How can I change the fun fact by swiping (more like a side scroll) vs. using the button?

Thanks in advance.

A simple way to implement this functionality is to add gesture recognizer to the view controller's view. First, create a new method to handle the swipe event.

func swipeRecognizer(recognizer: UISwipeGestureRecognizer) {
    self.showFunFact()
}

Then, in the viewDidLoad method, after "super.viewDidLoad()" you have to instantiate a new swipe recognizer, define it's direction and finally add it to the view.

let swipeLeft = UISwipeGestureRecognizer(target: self, action: "swipeRecognizer:")
swipeLeft.direction = UISwipeGestureRecognizerDirection.Left
self.view.addGestureRecognizer(swipeLeft)

Man that's cool to know! I am learning and went ahead and implemented your code for the swipe life gesture and it works flawless. Nice tidbit of code that allowed me to practice a new function. It is cool to see the possibilities of what we can do with this iOS devices....
