Get the filename of image saved to photos album

Gain a huge bounty with this seemingly easy question that has no attention.

In modern iOS (2017),

  • How do I set an NSCalendarUnitMinute repeatInterval on iOS 10 UserNotifications?
  • App rejected due to missing usage descriptions (Xcode8)
  • Continuous speech recogn. with SFSpeechRecognizer (ios10-beta)
  • Safe area layout guides in xib files - iOS 10
  • NSManagedObject subclasses duplicate declaration
  • Resume NSUrlSession on iOS10
  • here’s actually the only way I know to save an image to the iOS photos system, and get the filename/path.

    import UIKit
    import Photos
    func saveTheImage... () {
        UIImageWriteToSavedPhotosAlbum(yourUIImage, self,
    func image(_ image: UIImage, didFinishSavingWithError error: NSError?, contextInfo: UnsafeRawPointer) {
        guard error == nil else {
            print("Couldn't save the image!")
    func doGetFileName() {
        let fo: PHFetchOptions = PHFetchOptions()
        fo.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
        let r = PHAsset.fetchAssets(with: PHAssetMediaType.image, options: fo)
        if let mostRecentThingy = r.firstObject {
                for: mostRecentThingy,
                options: PHImageRequestOptions(),
                resultHandler: { (imagedata, dataUTI, orientation, info) in
                    if info!.keys.contains("PHImageFileURLKey") {
                        let path = info!["PHImageFileURLKey"] as! NSURL
                        print("Holy cow. The path is \(path)")
                    else { print("bizarre problem") }
        else { print("unimaginable catastrophe") }

    There are two problems with this:

    1. WTH ?!?

    2. It fails in racetrack conditions.

    This is amazingly unwieldy, and it seems worrysome in a number of ways.

    Is it really the way to go, today?

    You just saved image programmatically, so you can get the image from camera and save it with your path:

    //save image in Document Derectory
          NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
          NSString *documentsDirectory = [paths objectAtIndex:0];
          NSLog(@"Get Path : %@",documentsDirectory);
          //create Folder if Not Exist
          NSError *error = nil;
          NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/YourFolder"];
          if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
            [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
          NSString *yourPhotoName=@"YourPhotoName";
          NSString* path= [dataPath stringByAppendingString:[NSString stringWithFormat:@"/%@.png",yourPhotoName]];
          NSData* imageData = UIImagePNGRepresentation(imageToSaved); //which got from camera
          [imageData writeToFile:path atomically:YES];
          imagePath = path;
          NSLog(@"Save Image Path : %@",imagePath);
    extension PHPhotoLibrary {
        func save(imageData: Data, withLocation location: CLLocation?) -> Promise<PHAsset> {
            var placeholder: PHObjectPlaceholder!
            return Promise { fullfil, reject in
                    let request = PHAssetCreationRequest.forAsset()
                    request.addResource(with: .photo, data: imageData, options: .none)
                    request.location = location
                    placeholder = request.placeholderForCreatedAsset
                }, completionHandler: { (success, error) -> Void in
                    if let error = error {
                    guard let asset = PHAsset.fetchAssets(withLocalIdentifiers: [placeholder.localIdentifier], options: .none).firstObject else {

    I think you can do this with PHPhotoLibrary and PHObjectPlaceholder.

    If you want to get the filename just open the photoAlbum like this for example:

    if iOS 10 + (please set this key in info.plist : Privacy – Photo Library Usage Description)

    func openLibrary() {
        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
            let imagePicker = UIImagePickerController()
            imagePicker.delegate = self
            imagePicker.sourceType = .photoLibrary
            imagePicker.allowsEditing = true
            self.present(imagePicker, animated: true, completion: nil)
        } else {
            //alertWithTitle:"No gallery" message:"Unfortunately, we cannot access your photo gallery."

    then just conform to the protocol and implement this method:

    class ViewController: UIImagePickerControllerDelegate {
        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
             if let url = info[UIImagePickerControllerReferenceURL] as? URL {
             picker.dismiss(animated: true, completion: nil)

    hope this will help you,
    wish you all the best.

    Maybe this is a different approach but here’s what I’m doing in my app and I’m satisfied with it:

    func saveImage(image: UIImage, name: String) {
        var metadata = [AnyHashable : Any]()
        let iptcKey = kCGImagePropertyIPTCDictionary as String
        var iptcMetadata = [AnyHashable : Any]()
        iptcMetadata[kCGImagePropertyIPTCObjectName as String] = name
        metadata[iptcKey] = iptcMetadata
        let library = ALAssetsLibrary()
        library.writeImage(toSavedPhotosAlbum: image.cgImage, metadata: metadata) { url, error in
            // etc...

    If you don’t want to use ALAssetsLibrary, you’ll probably be interested in this answer.
