1 Button triggering random sounds (from an array?) in iOS - ios

Question

I've figured out how to trigger a sound when the button is pressed. I'm stuck on triggering a random sound when that same button is pressed. Since the audio player will take a string, I've generated a random number, but don't know how to insert that random number in the player. The code below is really broken so please bear with me there, I'm just stuck.
import UIKit
import AVFoundation
class ViewController: UIViewController {
#IBOutlet weak var mainButton: UIButton!
var sound1: AVAudioPlayer?
var sound2: AVAudioPlayer?
var sound3: AVAudioPlayer?
var sound4: AVAudioPlayer?
//There are many more sounds, but this is short for the example
var audioPlayer: AVAudioPlayer = AVAudioPlayer()
func setupAudioPlayerWithFile(file: NSString, type: NSString) -> AVAudioPlayer? {
let path = NSBundle.mainBundle().pathForResource(file as String, ofType: type as String)
let url = NSURL.fileURLWithPath(path!)
var audioPlayer : AVAudioPlayer?
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: url)
} catch {
print("Player not available")
}
return audioPlayer
}
override func viewDidLoad() {
super.viewDidLoad()
if let sound1 = self.setupAudioPlayerWithFile("sound1", type: "aif")
{self.sound1 = sound1}
if let sound2 = self.setupAudioPlayerWithFile("sound2", type: "aif")
{self.sound2 = sound2}
if let sound3 = self.setupAudioPlayerWithFile("sound3", type: "aif")
{self.sound3 = sound3}
if let sound4 = self.setupAudioPlayerWithFile("sound4", type: "aif")
{self.sound4 = sound4}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func buttonPressed(sender: AnyObject){
let audioArray: NSArray = ["1, 2, 3, 4"]
let range: UInt32 = UInt32(audioArray.count)
number = Int(arc4random_uniform(range))
sound(number)?.play()
}
}

class ViewController: UIViewController {
#IBOutlet weak var mainButton: UIButton!
// PUT SOUNDS AS STRINGS IN ARRAY
var arrayOfSounds = ["sound1", "sound2", "sound3", "sound4"]
var audioPlayer: AVAudioPlayer = AVAudioPlayer()
func setupAudioPlayerWithFile(file: NSString, type: NSString) -> AVAudioPlayer? {
let path = NSBundle.mainBundle().pathForResource(file as String, ofType: type as String)
let url = NSURL.fileURLWithPath(path!)
var audioPlayer : AVAudioPlayer?
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: url)
} catch {
print("Player not available")
}
return audioPlayer
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func buttonPressed(sender: AnyObject){
let range: UInt32 = UInt32(arrayOfSounds.count)
number = Int(arc4random_uniform(range))
//FIND OUT WHICH SOUND HERE
let sound = self.setupAudioPlayerWithFile(arrayOfSounds[number], type: "aif")
sound.play()
}
}
