[AVAudioPlayer在Xcode中崩溃？

Question

[当我从Xcode到iPhone7运行我的应用程序时，它在此行崩溃：

audioNSURL NSURL“ file：///private/var/containers/Bundle/Application/016483D7-D06F-4639-A026-CCD0B1F4B31F/Solo%20Mission.app/spaceMusic.mp3” 0x000000028217eac0

与GameViewController内部的AVAudioPlayer有关，这给了我此错误消息：

线程1：EXC_BAD_ACCESS（代码= 1，地址= 0x48）

请帮助解决这个问题，我已经检查了构建阶段，并且文件在那里。下面是所有代码。

import UIKit
import SpriteKit
import AVFoundation

class GameViewController: UIViewController {

var backingAudio = AVAudioPlayer()


 override func viewDidLoad() {
        super.viewDidLoad()

    let filePath = Bundle.main.path(forResource: "spaceMusic", ofType: "mp3")
    let audioNSURL = NSURL(fileURLWithPath: filePath!)

    do { backingAudio = try AVAudioPlayer(contentsOf: audioNSURL as URL) }
    catch { return print("Cannot Find The Audio") }

    backingAudio.numberOfLoops = -1
    backingAudio.volume = 1
    backingAudio.play()

已解决！

我尝试了许多不同的方法，但最终我解决了这个问题。我只需要编写不同的代码。这是我写的：

        var player: AVAudioPlayer?

        override func viewDidLoad() {
            super.viewDidLoad()


        func initializePlayer() -> AVAudioPlayer? {
            guard let path = Bundle.main.path(forResource: "spaceMusic", ofType: "mp3") else {
                return nil
            }

            return try? AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
        }
        player = initializePlayer()
        player?.play()

老实说，我不太清楚为什么会这样。但是，我将不胜感激。
