title: Xcode project CMD-Click on symbol to 'Jump to Definition' does not work
body: <p>I've been using Xcode 4.3.1 since it came out now and I've worked on many different projects since. Everything has always worked fine until this new project I'm working on.</p>
  <p>The code completion/code sense never finds anything. When I 'Command+Click' a variable or class normally it would jump to that but now I'm just getting:</p>
  <blockquote>
  <p>Symbol Not Found</p>
  </blockquote>
  <p>The <code>Jump to Definition</code> action is not working.</p>
  <p>If I open one of my older project while this bad one is open, the old ones still work for code sense and the new one doesn't.</p>
  <p>My partner is working on the same project, we both get the files from our repository and the code sense works on his machine for this project...just not mine.</p>
