title: Copy all debug build settings in Xcode
body: <p>I want to move all the build settings stuff to Xcode config files (<a href="http://robnapier.net/blog/build-system-1-build-panel-360" rel="nofollow">http://robnapier.net/blog/build-system-1-build-panel-360</a>), however in Xcode 4, when I <strong>select all and copy</strong>, it said "cannot copy build settings with multiple values", the reason is Debug and Release settings are mixed.</p>
  
  <p>So how can I copy only Debug information?</p>
