This page describes the debugging possibilites with XCode, though the tools and concepts are very similar in different IDEs (Integrated Development Environments).

== Debugger Console ==
Useful gdb commands when working with Objective-C:

'''print'''
* <tt>print (int) myVar</tt>
* <tt>print (int)[myObj retainCount]</tt>

'''po (print object)'''
* <tt>po [myObject description]</tt>

'''set'''
* <tt>set $myVar = @"Hello World!"</tt>
* use temporary variables
* great for creating and debugging short code snippets

'''show'''
* <tt>show values</tt> prints all temporary GDB vars (eg.: $myVar)
* <tt>help show</tt> to get all options

'''info symbol'''
* <tt>info symbol 0xa0b06174</tt>
* gets the symbolic name for an address

'''help'''
* <tt>help</tt> prints command classes
* <tt>help status</tt> prints list of commands

Don't forget there's a command completion (TAB & up-/down-arrows).
