How to Play Sound File in Swift 2 - swift

Question

I am using below code, but no sound is heard.
var audioPlayer:AVAudioPlayer?
override func viewDidLoad() {
super.viewDidLoad()
let path = NSBundle.mainBundle().pathForResource("SecondBeep", ofType: "wav")
let url = NSURL.fileURLWithPath(path!)
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: url)
} catch {
print("Player not available")
}
audioPlayer?.prepareToPlay()
audioPlayer?.play()
}
AVFoundation is imported properly and sound file is added to the project. Checked other stackoverflow topics but it does not help.
Tried to change to URLForResource but it does not help, too.
let path = NSBundle.mainBundle().URLForResource("SecondBeep", withExtension: "wav")
let url = NSURL.fileURLWithPath(path!.path!)
How can I fix the issue?

Answer 1

import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer:AVAudioPlayer!
override func viewDidLoad() {
super.viewDidLoad()
if let myAudioUrl = NSBundle.mainBundle().URLForResource("SecondBeep", withExtension: "wav") {
do {
audioPlayer = try AVAudioPlayer(contentsOfURL: myAudioUrl)
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch let error as NSError {
print(error.localizedDescription)
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 2

import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer: AVAudioPlayer! // Global variable
override func viewDidLoad()
{
super.viewDidLoad()
playVes()
// Do any additional setup after loading the view, typically from a nib.
}
func playVes() {
do {
self.audioPlayer = try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("123", ofType: "mp3")!))
self.audioPlayer.play()
} catch {
print("Error")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
