Ok, I know I’m late to the Xcode 4.6 party, but I found this line from the changelog pretty amusing. You might want to have a seat, because this new feature will blow you away:

• The elements of NSArray and NSDictionary objects can now be inspected in the Xcode debugger.
  

Yes, that’s right folks. You can now view the contents of arrays in the debugger.

Thanks Apple!
