title: Difference between code signing target and project
body: <p>I noticed that in Xcode I can set the Entitlements and Code signing settings both on:</p>
  
  <ul>
  <li>the Project (double click on the top item in Groups &amp; File, which has the name of the project)</li>
  <li>the Target (under Targets, double click on your project name). </li>
  </ul>
  
  <p>What's the difference between these two? I know that with header paths, one tends to override the other (without warning of course...).</p>
