WCSession didReceive文件不可移動的「沒有這樣的文件或目錄」

從iPhone傳輸文件到Apple關注後，我得到的錯誤WCSession didReceive文件不可移動的「沒有這樣的文件或目錄」

錯誤域= NSPOSIXErrorDomain代碼= 2「沒有這樣的文件或目錄」

我該怎麼辦錯了嗎？這些代碼片段：

iPhone的ViewController

func makeAction() { 
    let url = NSURL.fileURL(withPath: fileArray[0].object(at: 2) as! String) 
    var applicationDict = Dictionary<String, Array<AnyObject>>() 
    applicationDict["fileArray"] = fileArray 
    WCSession.default().transferFile(url, metadata: applicationDict) 
}

觀看InterfaceController

func session(_ session: WCSession, didReceive file: WCSessionFile) { 
DispatchQueue.main.async(execute: {() -> Void in 
    print("RECEIVED") 
    var applicationDict = Dictionary<String, Array<AnyObject>>() 
    applicationDict = file.metadata as! Dictionary<String, Array<AnyObject>> 
    self.fileArray = applicationDict["fileArray"]! 
    self.fileList = self.fileArray 

    let dirPaths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) 
    let tempDocsDir = dirPaths[0] as String 
    let docsDir = tempDocsDir.appending("/") 
    let filemgr = FileManager.default 

    do { 
     let fileName = self.fileArray[0].object(at: 1) as! String 
     try filemgr.moveItem(atPath: file.fileURL.path, toPath: docsDir + fileName) 
    } catch let error as NSError { 
     print("Error moving file: \(error.description)") 
    } 
    self.loadTableData() 
}) 
}
