我已经开始学习ios开发并被困在一个地方。我播放mp3文件的代码是

var bombSoundEffect: AVAudioPlayer!
let path = Bundle.main.path(forResource: "faded", ofType:"mp3")!
let url = NSURL(fileURLWithPath: path)

 do {
        let sound = try AVAudioPlayer(contentsOf: (url as NSURL) as URL)
        bombSoundEffect.play()

    } catch {
        print("couldn't load file :(")
    }
    if bombSoundEffect != nil {
        bombSoundEffect.stop()

There's lots wrong with your code, but it's a sunny day, so try something like this…

您的代码有很多问题,但这是一个阳光灿烂的日子,所以尝试这样的事情......

func playSound() {
    guard let url = Bundle.main.url(forResource: "faded", withExtension: "mp3") else { return }

    let bombSoundEffect = try? AVAudioPlayer(contentsOf: url)
    bombSoundEffect?.play()
}
