Hi Omotayo

Yes, it is possible to add sound to the button so when it is clicked it makes the sound. Off course you must add the sound file to the project and connect the button as usually with an @IBAction. If you import AVFoundation into the View Controller that the button belongs to, you can then use that to play the sound file when the button is pressed. You can find my solution here below: 

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var soundEffectPlayer: AVAudioPlayer?

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

    func playSoundEffect(filename: String) {
        let url = NSBundle.mainBundle().URLForResource(filename, withExtension: nil)
        if (url == nil) {
            print("Could not find file: \(filename)")
            return
        }

        var error: NSError? = nil
        do {
            soundEffectPlayer = try AVAudioPlayer(contentsOfURL: url!)
        } catch let error1 as NSError {
            error = error1
            soundEffectPlayer = nil
        }
        if let player = soundEffectPlayer {
            player.numberOfLoops = 0
            player.prepareToPlay()
            player.play()
        } else {
            print("Could not create audio player: \(error!)")
        }
    }

    @IBAction func playSoundButtonPressed(sender: AnyObject) {
        playSoundEffect("pop.wav")
    }

}

I hope this helped you... Keep coding :) / Jens

Hello sorry im abit lost how would i apply it in this particular code

import UIKit

class ViewController: UIViewController {

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

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


override func viewDidLoad() {
    super.viewDidLoad()
        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()
}

}
