我有下一个从 url 下载文件的代码。但我收到下一个错误:

失败并出现错误:错误域=NSCocoaErrorDomain 代码=516 ““CFNetworkDownload_85Dvq4.tmp”无法移动到“文档” 因为已经存在同名项目。” UserInfo=NSSourceFilePathErrorKey=/Users/otani/Library/Developer/CoreSimulator/Devices/8BABC203-7FD9-4F03-BF0D-D660DD29CCDE/data/Containers/Data/Application/09C714D3-F185-4289-91DB-13B21557B784/tmp/CFNetworkDownload_85Dvq4。温度, NSUserStringVariant=( 移动),NSDestinationFilePath=/Users/otani/Library/Developer/CoreSimulator/Devices/8BABC203-7FD9-4F03-BF0D-D660DD29CCDE/data/Containers/Data/Application/09C714D3-F185-4289-91DB-13B21557B784/Documents/temp.法尔格, NSFilePath=/Users/otani/Library/Developer/CoreSimulator/Devices/8BABC203-7FD9-4F03-BF0D-D660DD29CCDE/data/Containers/Data/Application/09C714D3-F185-4289-91DB-13B21557B784/tmp/CFNetworkDownload_85Dvq4.tmp, NSUnderlyingError=0x7fea5a53a9a0 错误域=NSPOSIXErrorDomain Code=17 "文件存在"

下载文件代码如下:

func downloadFile(let url: String!)
        self.downloadHUD()
        Alamofire.download(.GET, url)  temporaryURL, response in
            let documentsUrl =  NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
            let fullPath = documentsUrl.URLByAppendingPathComponent(Misc.pathToSaveFile)
            if (NSFileManager.defaultManager().fileExistsAtPath(fullPath.absoluteString))
                   try! NSFileManager.defaultManager().removeItemAtURL(fullPath)
            
            return fullPath

        
        .progress  bytesRead, totalBytesRead, totalBytesExpectedToRead in
                dispatch_async(dispatch_get_main_queue()) 
                    self.hud.progress = Float(totalBytesRead) / Float(totalBytesExpectedToRead)
                    print("Total bytes read on main queue: \(totalBytesRead)")
            
        
        .response  _, _, _, error in
                if let error = error 
                    print("Failed with error: \(error)")
                 else 
                    print("Downloaded file successfully")
                    self.hideHUD()
                
        

    

错误上线

print("Failed with error: \(error)")
