title: How do I look at an object in Xcode's debugger?
body: <p>I have a simple question about debugging on Xcode and GDB.</p>
  
  <p>I often run into an error:</p>
  
  <pre><code>unrecognized selector sent to instance 0x1081ad0
  </code></pre>
  
  <p>which makes the program load into GDB. Is there an easy way to examine what instance is located in that memory from GDB?</p>
