Xcode 4 Unleashed [Repost]

In Xcode 4 Unleashed, renowned Mac/iOS developer Fritz Anderson shows how to use Apple’s powerful new Xcode 4 integrated development environment to develop outstanding software with the least effort possible.
Anderson demonstrates Xcode 4 by walking through the construction of three full applications: a command-line tool, an iOS app, and a Mac OS X application. These case-study projects offer practical insights and realistic best practices for efficiently utilizing Xcode 4 in day-to-day development.
Next, he drills down to offer an even deeper understanding of Xcode 4’s most powerful capabilities. Through practical examples, he shows experienced Apple developers how to move to Xcode 4’s “browser” model from older document-based approaches. You’ll also find thorough, up-to-the-minute coverage of key tasks ranging from builds and profiling to documentation.
He concludes with a chapter-length roundup of “tips, traps, and features” for maximizing your productivity with Xcode 4—whether you’re writing iOS apps or Mac applications, working solo, or as part of a large development team.
