title: How to enable Objective-C exceptions on Xcode 4.2?
body: <p>maybe I'm being daft or something but I've added a @try @catch block to my code and I'm getting a "cannot use @try with object-c exceptions disabled" error that prevents compilation... </p>
  
  <p>How do I turn it on? I've searched all around, added the exception breakpoint thing and no results...How do I do this?</p>
