        I'm in throubles accessing original HEIC and DNG files from my iOS 11 app, written in Swift; following the Apple developer's documentation, to access original files it's enought to set imagePicker.imageExportPreset = UIImagePickerController.ImageURLExportPreset.current but on the UIImagePickerController.InfoKey.imageURL I still get an URL pointing to a JPEG file; I know the choosen pictures are HEIC and DNG because exporting as original on Mac photo app I get the original file format.

        This is the complete code I use:


        @IBAction func openRoll(_ sender: Any) {
          if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
          let imagePicker = UIImagePickerController()
          imagePicker.delegate = self
          imagePicker.sourceType = .photoLibrary
          imagePicker.allowsEditing = false
          imagePicker.imageExportPreset = .current
          self.present(imagePicker, animated: true, completion: nil)


        And on delegate:

        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
          let image = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
          let path = info[UIImagePickerController.InfoKey.imageURL] as! NSURL
          NSLog("URL: \(path.absoluteString)")
          NSLog("Export: \(picker.imageExportPreset.rawValue)")
          dismiss(animated:true, completion: nil)
          // ...code to use the image!


        Thank you very much for help, suggestions and working snippets.
