title: Target OS X 10.7+ on Xcode 5
body: <p>I've been trying to build an app that supports 10.7+ using Xcode 5 on 10.9.  I can get 10.8+ working but have not succeeded in getting 10.7 to work.</p>
  
  <p>I've tried the following:</p>
  
  <ul>
  <li>disabled base internationalization (i think)</li>
  <li>turned off autolayout in my xib</li>
  <li>set 10.7+ as the target for my xib</li>
  <li>copied in the 10.6 and 10.7 SDKs from 4.3.3 into my Contents/Developer/Platforms/MacOSX.platforms/Developers/SDKs folder</li>
  <li>set deployment target to 10.7</li>
  <li>set by base sdks to 10.7</li>
  </ul>
  
  <p>When I do the above (mainly the deployment target and base SDKs) I can't run on 10.9.  I get the following error message.</p>
  
  <p>Xcode cannot run using the selected destination.</p>
  
  <p>This seems exceptionally difficult.  What am I missing?  What else can I try?</p>
