Create a random audio sound generator - ios

Question

Thanks for replying.
I am trying to make a program when I press a button once, two random sounds will play. I can get the random sounds to play if I press the button, but I am looking that if I press the button, the random sound will play differently each time.
I can paste the sounds together to hear them in the sequence I want them, but I would like swift to generate the sounds.
I thought of the AVqueplayer to make it as a playlist. I was thinking this can be like a pair of dice in an analogy. For example, if I were to throw the dice down, the random sounds will occur.
I am still a newbie, and tried to figure this out on my own, because it seemed so simple, but I am out of options now.
Here is what I got so far. This will play a random sound when I press the button each time.
import UIKit
import AVFoundation
class ViewController: UIViewController {
var player: AVAudioPlayer = AVAudioPlayer()
var sounds = ["sound1", "sound2", "sound3"]
override func viewDidLoad() {
super.viewDidLoad()
}
override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
if event!.subtype == UIEventSubtype.motionShake {
let randomNumber = Int(arc4random_uniform(UInt32(sounds.count)))
let fileLocation = Bundle.main.path(forResource: sounds[randomNumber], ofType: "mp3")
var error: NSError? = nil
do { try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation!))
player.play()
} catch {}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Using the same code, and adding a second random number with matching file location will allow the sounds to play back to back, both being random:
import UIKit
import AVFoundation
class ViewController: UIViewController {
var player: AVAudioPlayer = AVAudioPlayer()
var sounds = ["sound1", "sound2", "sound3"]
override func viewDidLoad() {
super.viewDidLoad()
}
override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
if event!.subtype == UIEventSubtype.motionShake {
let randomNumber1 = Int(arc4random_uniform(UInt32(sounds.count)))
let randomNumber2 = Int(arc4random_uniform(UInt32(sounds.count)))
let fileLocation1 = Bundle.main.path(forResource: sounds[randomNumber1], ofType: "mp3")
let fileLocation2 = Bundle.main.path(forResource: sounds[randomNumber2], ofType: "mp3")
//var error: NSError? = nil
do {
try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation1!))
player.play()
try player = AVAudioPlayer(contentsOf: URL(fileURLWithPath: fileLocation2!))
player.play()
} catch {}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
