title: Why can't I release an object anymore?
body: <p>After I updated to Xcode 4.2, I can no longer release anything.
  When I start typing "release" it suggest "release" but with a red line across.</p>
  
  <p>If I write it anyway it shows an error and displays these two messages:</p>
  
  <p>'release' is unavailable: not available in automatic reference counting mode
  Automatic Reference Counting forbids explicit message send of 'release'</p>
  
  <p>Does anyone know what I can do?</p>
