Query: buy Hillegass instead

This book is upperquartile (as books of this type go). It has many good points. But it has one fatal drawback: there is a much better book available. Hillegass (1) is a professional trainer with oodles of classroom experience and that shines through in his book - he trained many of the Apple coders who now work on Cocoa, (2) has been involved with Cocoa from its inception. As icing on the cake, the 3rd ed of his book is up-to-date (2008), whereas this is not.I ploughed through Garfinkel and Mahoney first (on the strength of the O'Reilly reputation and good experiences with other O'Reilly books). I still did not understand Cocoa particularly well. Then I ploughed through several hundred pages of the Applie Guides. Finally, I bought Hillegass. I wish I had found it first. The Apple guides, or some of them, are quite good, but you need a good grounding first.
