问题:

Hi I am trying to save a downloaded mp4 file to my gallery.

Downloading the url by using , downloadTask

in

func urlSession(_ session: URLSession,                     downloadTask: URLSessionDownloadTask,                     didFinishDownloadingTo location: URL){ } 

I am getting the url

file:///private/var/mobile/Containers/Data/Application/8D761DFE-C050-426D-B91C-61DE441FB496/Library/Caches/com.apple.nsurlsessiond/Downloads/com.te.dn/CFNetworkDownload_KFSYSW.tmp 

I am creating a path by using,

let path = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)         let documentDirectoryPath:String = path[0]         let fileManager = FileManager()         let destinationURLForFile = URL(fileURLWithPath: documentDirectoryPath.appendingFormat("/file1.mp4"))  if fileManager.fileExists(atPath: destinationURLForFile.path){          }         else{             do {                 try fileManager.moveItem(at: location, to: destinationURLForFile)                 // show file              }catch{                 print("An error occurred while moving file to destination url")             }         } 

I could successfully move the file (not getting any error while moving).

Then I trying to save the file getting error

let url = URL(fileURLWithPath: destinationURLForFile.path) 

url value is :

file:///var/mobile/Containers/Data/Application/8DF0C849-56A1-42B3-A081-0C992D18F973/Documents/file1.mp4           PHPhotoLibrary.shared().performChanges({             PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: url)         }) { saved, error in             if saved {                 let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)                 let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)                 alertController.addAction(defaultAction)                 self.present(alertController, animated: true, completion: nil)             }             else             {                 print(error?.localizedDescription ?? "f")             }          }
