While Cocos2D is compatible with ARC, simply enabling ARC in the project’s Build Setting will throw several hundreds of errors in your face. Cocos2D doesn’t provide ARC-enabled project templates. Thus this tutorial about how to enable ARC in a newly created Cocos2D Xcode Project.
While none of these steps are overly difficult, you’ll notice there’s plenty of steps to perform. Unavoidably, and on the off chance you don’t already know, I’d like to recommend Kobold2D to you if you want to write ARC enabled Cocos2D apps. Because none of the steps below, really zero, zilch, nada, niente, keine are necessary to enable ARC in Kobold2D. That’s because it ships with 15 template projects all of which have ARC enabled out of the box. And Kobold2D 2.0 with cocos2d-iphone 2.0 is just around the corner.
Self-advertisment aside, these steps are tested with cocos2d-iphone v2.0 but should also work with cocos2d-iphone v1.1 – but admittedly I haven’t tested the process with the v1.1 version. If you find anything that’s not quite working with v1.1 please leave a comment. Preferably with the solution, that’ll be awesome!

What do you do if your app doesn’t behave as it should, or even crashes?
Answer A: Post your problem in just about every programming forum.
Answer B: Use the Xcode Debugger to analyze what’s going wrong.
Since most of you already know how to do A I’ll focus on B in this Xcode 4 Debugging Crash-Course. It’s kind of aimed at beginning Xcode developers but that’s just because I hope – against better knowledge – that experienced developers already know that … thing … that debugger stuff. Ya know?
