title: Getting the hex address of an instance in XCode
body: <p>Is there a way to get the hex address of an instance object in the debug window of XCode via NSLog?</p>
  
  <p>I have a set of NSArray and NSDictionary objects and I want to get the address of the instance, not the contents.</p>
  
  <p>Trying [obj description] will tell me the contents but not address.</p>
