title: Xcode evaluating expressions while debugging
body: <p>I am working on an iPhone app. I am a full-time Java developer and I am used to using Eclipse where I can put a breakpoint in and stop the process. Then, I can type in any expression that I want and Eclipse will evaluate it using the values from that point in the process.</p>
  
  <p>Is there a way to do that in Xcode? I want to be able to stop at a breakpoint and then enter some code to evaluate it. The gdb console will let me do <code>po</code> (<a href="http://support.apple.com/kb/ta45906" rel="noreferrer">print-object</a>), but it is really limited. Any help?</p>
