title: Xcode Asset Catalog issues
body: <p>I just started using Asset Catalogs in Xcode, so had few questions about better organization of catalog.</p>
  
  <p>I have over 100 button images, each image has 5 versions(@1x, @2x, @3x, @1x iPad, @2x iPad).</p>
  
  <ol>
  <li><p>One way is to create 100 image sets in the catalog file. However, that would be too clumsy. Is it possible to group related image sets together?</p></li>
  <li><p>Is there a better way of importing 500 images than manual drag and drop?</p></li>
  </ol>
