title: Turning off Asset Catalog Compiler warnings
body: <p>Is there a way to turn off the <strong>Asset Catalog Compiler</strong> warnings in Xcode 5?</p>
  
  <p>We've got a project that needs to be shared between Xcode 6 and 5 -<br>
  every time asset catalogs are opened in v6 a 3rd image is added for super-hi resolution.</p>
  
  <p><strong>Example:</strong></p>
  
  <pre><code>/Users/ME/Source/Projects/Stuff/Resources/Images.xcassets: The image set "arrow" has an unassigned image.
  </code></pre>
  
  <p>Xcode6 doesn't seem to care but v5 issues <em>"unassigned image"</em> warnings for each such asset.</p>
  
  <p>Any hints much appreciated!</p>
