How to get file name in UIImagePickerController with Asset library?

Question

I want to get the file name from UIImagePickerController. I do not want to use ALAssetLibrary because it is deprecated in iOS 9. I have used the following code

Answer 1

Code:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let imageURL = info[UIImagePickerControllerReferenceURL] as NSURL
    let imageName = imageURL.path!.lastPathComponent
    let documentDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as String
    let localPath = documentDirectory.stringByAppendingPathComponent(imageName)
    let image = info[UIImagePickerControllerOriginalImage] as UIImage
    let data = UIImagePNGRepresentation(image)
    data.writeToFile(localPath, atomically: true)
    let imageData = NSData(contentsOfFile: localPath)!
    let photoURL = NSURL(fileURLWithPath: localPath)
    let imageWithData = UIImage(data: imageData)!
    picker.dismissViewControllerAnimated(true, completion: nil)
}
