Debugging an ARC Mac Application on Snow Leopard

Brian Webster:

Thus far, I’ve been doing most of my development and testing using Xcode 4.3 running on OS X 10.7, but I wanted to start to do more thorough testing on 10.6. ARC is supported on both versions of OS X (though with a few minor restrictions on 10.6), but as I quickly discovered when I tried building my application with Xcode 4.2 on 10.6, building an ARC application requires linking against the 10.7 SDK, which is only possible if you’re running Xcode on 10.7. So while I can run the app fine on 10.6, not being able to build on 10.6 makes it a little tricky to use Xcode’s debugger to debug the application.
