title: Xcode 5 debugger doesn't print objects
body: <p>i'm having problem debugging from the console with lldb debugger after upgrading to xcode 5. i used to type <code>po object</code> and it used to work fine, however now i get the error</p>
  
  <pre><code>error: instance method 'performBlock:afterDelay:' has incompatible result types in different translation units ('id' vs. 'void')
  note: instance method 'performBlock:afterDelay:' also declared here
  </code></pre>
  
  <p>here is a <a href="http://new.tinygrab.com/a42d6a89a00c557e538a01c6d2dfd2eb1daf745073.png">screenshot</a> of the stack, the code where the debugger stopped at, the values in the visual debugger and the debugger console. what might be the problem, is it a bug in xcode 5 or is there something i can do to rectify this?</p>
