We find in this book (618 pages) examples rather original and already complex enough for a learning-programming book on Macintosh; what is motivating and helps advance the understanding of Cocoa provided to devote enough time. This book seems to be an adaptation of a book written at the time for NextStep, the ancestor regardless of kind of Cocoa. Summary calculator is built there (6 of 21 chapters) and a grapher (6 chapters of 21) among other things. It is older, it will also fit (e.g. it is still Project Builder that is used and not Xcode) Another book (752 pages) that can be the companion of it and not give to the approach not to build a standard Cocoa application Recipes for Macintosh Mac OS X: The Vermont Recipes. Two purchases I have not missed.
