swift - iTunesLibrary 获取所有音乐

Question

我是 swift 4 的新手。我正在尝试开发一个简单的 mac 程序来从 iTunesLibrary 获取所有音乐歌曲。我确实签署了我的代码并将 iTunesLibrary.framework 导入到项目中。但是我收到有关 iTlib XPC 连接错误的错误消息:

2018-05-29 19:51:16.277312+0700 KODE[2325:47137] ITLib received XPC_ERROR_CONNECTION_INTERRUPTED connection error (can be ignored). 2018-05-29 19:51:16.277410+0700 KODE[2325:47137] ITLib xpc error: Connection interrupted 2018-05-29 19:51:16.277441+0700 KODE[2325:47072] Assertion failure: status == noErr (100005)

这是我的代码

override func viewDidLoad() {
    super.viewDidLoad()

    let library: ITLibrary

    do {
        library = try ITLibrary(apiVersion: "1.0")
    } catch {
        print("Error occured!")
        return
    }

    let tracks = library.allMediaItems

    for track in tracks {
        print(track.album.title!)
    }

    // Do any additional setup after loading the view.
}

如果您有沙盒应用程序，请转至功能/“应用程序沙盒”/“文件访问”/“音乐文件夹”。将“无”更改为“只读”。它帮助了我。此外，应用程序必须是 properly signed .
