title: Debugger lldb says my object is nil when is not ?
body: <p>Recently I upgraded my project settings in Xcode 4.3 and now I use the latest llvm debugger: <strong>lldb</strong></p>
  
  <p>However (sometimes) I have the impression the debugger is not giving me the correct info? Could this be possible?</p>
  
  <p>For example, The debugger says <code>_documentsItem</code> is <code>nil</code> (both in in the console and when mouse-over-ing the ivar). But I know it's <strong>NOT</strong>,  that is why I can see it (an UIBarButtonItem) and more important that is why the app stopped at the shown breakpoint)</p>
  
  <pre><code>if (_documentsItem) { ...
  </code></pre>
  
  <p>In fact most of my properties return nil too :(
  Is there a way I make sure the debugger is doing fine?</p>
