title: How do I save a movie to a custom named album in swift
body: <p>in objective C one could save a video to a custom named photo album using code similar to what follows</p>
  
  <pre><code>-(void)saveImage:(UIImage*)image
           toAlbum:(NSString*)albumName
  withCompletionBlock:(SaveImageCompletion)completionBlock;
  </code></pre>
  
  <p>I can't figure out how to do this ins swift, when I look at the definition of ALAssetsLibrary I don't see any function call toAlum or savedImage. I can't seem to figure this out?</p>
