我在对我的应用程序后端进行API调用时遇到了问题,现在每个连接都会提示

CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    atyp = http;
    class = inet;
    "m_Limit" = "m_LimitAll";
    ptcl = http;
    "r_Attributes" = 1;
    srvr = "myappsurl.com";
    sync = syna;
}

我有点失落,因为我不确定是什么导致了这个,或者CredStore甚至做了什么.CredStore在iOS中的用途是什么？

我正在尝试通过AVPlayer播放MP3文件:

let url = URL(string: "http://transom.org/wp-content/uploads/2004/03/stereo_40kbps.mp3?_=7")!
let asset = AVURLAsset(url: url)
let item = AVPlayerItem(asset: asset)
let player = AVPlayer(playerItem: item)
player.play()

但是我得到了下一个日志:

2017-09-26 21:57:07.906598+0300 MyApp[7558:1177816] CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    class = inet;
    "m_Limit" = "m_LimitAll";
    "r_Attributes" = 1;
    sync = syna;
}

我想这是因为iOS 11和Xcode 9,但我不知道如何解决这个问题.
