Swift AVAudioPlayer导致主线程中出现断点

我对主线程和错误进行了断点检查，以测试我的代码，出于某种原因，

AVAudioPlayer

导致断点，我应该将其添加到主线程中吗

  do {
            let sound = try AVAudioPlayer(contentsOf: url)
            self.oneTimePlayer.append(sound)
                sound.prepareToPlay()
                sound.volume = volume
                sound.play()
        } catch {
            print("[PLAY SOUND][DELEGATE][STATIC] error loading file -> \(fileName)")
        }
