Swift无法使用avaudioplayer在模拟器上播放音频

Question

我一直在尝试使用Xcode中的Swift在iOS模拟器上播放音频，但是我得到的只是以下错误。是什么引起了这个问题？

2018-11-08 21:30:14.752040-0800 [9055:150546] Error loading /Library/Audio/Plug-Ins/HAL/NRDAudioClnt.plugin/Contents/MacOS/NRDAudioClnt:  dlopen(/Library/Audio/Plug-Ins/HAL/NRDAudioClnt.plugin/Contents/MacOS/NRDAudioClnt, 262): no suitable image found.  Did find: /Library/Audio/Plug-Ins/HAL/NRDAudioClnt.plugin/Contents/MacOS/NRDAudioClnt: mach-o, but not built for iOS simulator
2018-11-08 21:30:14.752328-0800 [9055:150546] Cannot find function pointer NRDACLN_New_Instance for factory <CFUUID 0x600002b8d660> 3E9FAD07-70A8-4980-B39B-BB8B905C9872 in CFBundle/CFPlugIn 0x7fe6d950d740 </Library/Audio/Plug-Ins/HAL/NRDAudioClnt.plugin> (bundle, not loaded)

这是我在运行下面的代码时遇到的错误。

let url = Bundle.main.url(forResource: "beat3", withExtension: "wav")

do {
    try openingAudioPlayer =  AVAudioPlayer(contentsOf: url!)
    openingAudioPlayer.numberOfLoops = -1
    openingAudioPlayer.play()
} catch let error {
}
