title: Can you change the current line of execution while debugging in Xcode?
body: <p>The debugger lets me drag the little green line pointer, but it seems it has no effect at all and when I step it behaves as though I never dragged it.</p>
  
  <p>Just wondering if the bug is:</p>
  
  <ul>
  <li>That it's not correctly changing the current execution pointer, or</li>
  <li>That it's allowing me to drag the thing at all.</li>
  </ul>
