unable to play sound on button pressed

Question

I have the following code, I always get a breakpoint on "try btnSound". Not sure where I'm doing wrong. The Sound file is in main folder.

import UIKit

import AVFoundation

class ViewController: UIViewController {

    @IBOutlet weak var outputLbl: UILabel!

    var btnSound: AVAudioPlayer = AVAudioPlayer()


    override func viewDidLoad() {
        super.viewDidLoad()

        let path = Bundle.main.path(forResource: "btn", ofType: "wav")

        do {

            try btnSound = AVAudioPlayer(contentsOf: URL(fileURLWithPath: path!))

            btnSound.prepareToPlay()

        } catch let err as NSError {
            print(err.debugDescription)
        }

    }
    @IBAction func numberPressed(btn: UIButton!){
        btnSound.play()
    }

}

Your code claims there is a file _btn.wav_ in your app bundle. There isn’t. The term `path!` means “crash if there is no such path.” Thus, you crash. You crashed because that is what you said to do. — matt, Dec 29 '18 at 08:16
matt - Thanks for the reply. "btn.wav" file is already present in my bundle, but still it doesn't play the sound. "main folder" means my audio file is present in bundle itself. Below is my files structure: - filename.xcodeproject - filename - btn.wav - AppDelegate.swift - ViewController.swift and so on — iCodeByte, Dec 29 '18 at 14:40

OK. Thank you, people. I just used:

var audioPlayer = AVAudioPlayer()

    let source = Bundle.main.path(forResource: "btn", ofType: "wav")

    do {
        audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: source!))
        audioPlayer.prepareToPlay()
    } catch let err as NSError {
        print(err.debugDescription)
    }

I renamed "path" to "sound" and it started working. Not sure what exactly the issue was.
