title: Useful Xcode DEBUG commands to use in console
body: <p>I've been wondering but haven't found anywhere an useful list of commands that are useful in Xcode.</p>
  
  <p>One I know, and I use a lot is Backtrace which the input command is <code>bt</code> , after you encounter an app crash after uncaught exceptions it sometimes gives an int where the problem could be.</p>
  
  <p>Can you share more useful commands that become handy and could let us interact with the debugger and the app itself?</p>
  
  <p>Thank you</p>
