I'm writing this after the announcement of Apple's Swift language, mainly to address the question of whether this book is still relevant for Mac/iOS developers. I think it is; although a lot of people are excited to start working with Swift, C++ hasn't been totally displaced by its successors, and I don't think Objective-C will be either, with a quarter century of working legacy code in it. Swift isn't shipping yet anyway, and there's no word on whether the compiler will be proprietary or open source. And it is a bit on the expensive side for its size; it's certainly cheaper to use Apple's materials. But it's a good introduction to the process of Cocoa app design.
This book is a good guide. It doesn't have everything about iOS, OSX, and Cocoa programming, but there's enough in here for you to understand the fundamentals and start putting together some projects. The book starts off with an introduction to xCode (through the writing of a simple iOS app, then introduces some of the fundamentals of Objective-C and Cocoa Foundation. Each chapter after that introduces another aspect of Cocoa programming. I've enjoyed reading it thus far, and I'm learning a lot. This has satisfied a big need.
I'm already a programmer (C/C++, Perl, MATLAB, and some Java), so I can't offer anything from the perspective of someone who doesn't know how to program. I will say I think you'll get more out of this book if you have experience with a programming language, preferably C. If you don't have any experience you should probably get familiar with Objective-C by reading a book about it (Apple has a guide you can download).
Apple’s new language, Objective-C will be obsolete. Objective-C will be around for many years as Swift continues to evolve into a mature language. Anyone who wants to be a great Apple developer should learn both Objective-C and Swift. Because, if you plan to be more than a hobby developer you will be supporting legacy applications written in Objective-C.
That said, Learning Cocoa With Objective-C: Developing for the Mac and iOS App Stores is a great book for anyone coming from another language. The book isn’t difficult to understand but a brand new developer might have a hard time learning Objective-C only with this book. The book covers the basics of Xcode, core parts of Objective-C, and moves into frameworks like Core Location (Mapping), Notifications, and iCloud. At WWDC this year Apple announced major changes / improvements to iCloud that will make the iCloud chapter outdated.
Overall Learning Cocoa With Objective-C: Developing for the Mac and iOS App Stores is an excellent book for anyone looking to learn Objective-C to create Mac or iOS applications.
CAVEAT: With Apple's announcement of Swift, consider carefully if you want to invest your time and energy learning Objective-C. Objective-C has been around for something like 30 years. Swift it brand-spanking new. If I were a beginning programmer, I'd consider directing my energy to learn Swift, firstly, and then Objective-C for complete marketability.
WHAT I LIKED:
- There are downloadable code examples available from the publisher. However, I couldn't see how to download all the examples all at once; it seemed like I had to download them one at a time.
- There are tips, notes and warnings throughout, many of which will be useful only to those who have some prior experience with Objective-C and developing for OS X.
- The size of the book is about right at 350 pages. Not too small, not too big and bulky.
