EZAudioFile打开音频文件异常

Question

我有以下代码

import AudioKit
import AudioKitUI
import Cocoa

class ViewController: NSViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let path = "/Users/user/Desktop/TestFile.mp3"
        let fileManager = FileManager()
        let fileExists = fileManager.fileExists(atPath: path)
        print("fileExists = \(fileExists)")
        let url = NSURL.fileURL(withPath: path)
        print("url = \(url)")
        let file = EZAudioFile(url: url)

    }
}

这将产生以下输出

fileExists = true
url = file:///Users/user/Desktop/TestFile.mp3

Error: Failed to create ExtAudioFileRef (-54)

调用EZAudioFile(url: url)时，应用程序崩溃。

这是为什么，怎么解决？
