The definitive guide to Xcode 4,
This review is from: Mastering Xcode 4: Develop and Design (Paperback)
After years of using earlier versions of Xcode, I was dismayed to discover that Xcode 4 appeared to be a complete re-imagining of the product -- thus leaving me a virtual noob when it comes to using the latest version of my favorite IDE.
I think it's vitally important to deeply understand the basic concepts of an IDE to be productive in it. However, Xcode 4 introduced an array (har, har) of entirely new or significantly altered abstract concepts: Schemes, Workspaces, Behaviors, Projects, Navigators, etc. -- All with very little information on what they were or direction on how to use them effectively.
That's why this book is important and why you'll want it. To be a great Mac or iOS developer you must fully grok Xcode. But Xcode 4 is far too complex for anyone to jump right in and simply 'get it'. This book has all the information you need to understand those vitally important concepts on a deep level. Every significant concept of the IDE is explained and discussed in great detail.
As a bonus, the book contains *tons* of small tips on hidden or hard-to-find commands and key combinations which you'll quickly find yourself using to good effect. You'll find at least 2 or 3 gems like this in every chapter, and be grateful for it.
Finally, the author has an excellent sense of humor and has (almost unbelievably) managed to strike just the right balance between seriousness and light-hearted humor. You'll find yourself occasionally chuckling at a small joke or clever jibe, rather than groaning as one so often does when reading attempts at humor in tech writing.
If you are serious about iOS or Mac development, you should own this book.
