Looking at the product description, it is still using Xcode 3 and not Xcode 4 as the development environment. Nothing wrong with that, you still learn the language etc, but IF it is a new book?, why not use the Xcode 4 environment to learn, otherwise it would be confusing to the learner who would most likely be using Xcode 4 and therefore would also be trying to get their head around the dev environment, while seeing the examples etc being done in the Xcode 3 dev environment.
