title: How to get image from camera roll by name/identifier in Swift
body: <p>in my app I'm taking a picture and save it in camera roll by:</p>
  
  <pre><code>UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
  </code></pre>
  
  <p>Later in another screen, I want to display it to the user.
  As I don't want to store the whole picture, is there any possibility to load an image from camera roll using the image name or an identifier? (And of course set the image name or saving the identifier when saving the picture)</p>
  
  <p>Any help would be appreciated!</p>
