Button Not Working in App

I'm in the process of building the simple iPhone app with Swift and I'm having an issue getting my buttons to work.

I'm doing everything shown in the video from start to finish, but when I run the app in the simulator I can SEE the label and button, but I cannot click the button. Is there a step I'm missing to make the button functional. I tried deleting the button from the interface and then adding it again. It doesn't work as a clickable button even before I add the IBAction method.

Here's my code: 

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var funFactLabel: UILabel!

    let factbook = FactBook()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        funFactLabel.text = factbook.randomFact()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    @IBAction func newRandomFactButton() {
        funFactLabel.text = factbook.randomFact()
    }

}

        UIView.animateWithDuration(4.0, animations: {
            self.ChangeTheFact.text = self.factBook.randomFact()
            self.ChangeTheFact.frame.origin = CGPoint(x: 0, y: 667)
            self.view.backgroundColor = randomColor
            self.buttonColor.tintColor = randomColor

            }, completion: {
                (finished : Bool) in
                UIView.animateWithDuration(4.0){
                self.ChangeTheFact.frame.origin = CGPoint(x: 375, y: 667)
                }
            })



    }

This is how the viewController file should look 

class ViewController: UIViewController {

    @IBOutlet weak var funFactLabel: UILabel!
    @IBOutlet weak var funFactButton: UIButton!

    let factBook = FactBook()
    let colorWheel = ColorWheel()


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        funFactLabel.text = factBook.randomFact()





    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func showFunFact() {

        var randomColor = colorWheel.randomColor()

        view.backgroundColor = randomColor

        funFactButton.tintColor = randomColor


        funFactLabel.text = factBook.randomFact()
       }
