Since Will and I couldnt agree on dedicating this to his parents or mine, we hereby dedicate this book to the game #Starhawk. Come play the authors and discuss Xcode in the regularly appearing Old-N-Slow server.

So youve decided to write applications for OS X or iOS. You sit down at your Macintosh, start up Xcode, and... what? Create a project? Create a file? Make a storyboard? Build a Core Data model? What?

For an operating system that prides itself on being accessible to many, Xcode can appear as an insurmountable obstacle to an unprepared developer. With an iTunes-like interface, and more panels, palettes, menus, and buttons than you can count, even a simple Hello World application can seem daunting. Apple, while diligent in providing documentation, provides very few resources for developers who understand programming fundamentals but not their OS X/iOS implementation. Thats where this book comes in.

Xcode offers a range of integrated tools for everything from data modeling to performance analysis and optimization. Teach Yourself Xcode in 24 Hours takes 24 of the most important aspects of Xcode development and condenses them down into easily understandable chunks. To help convey some of the core concepts, you work with real projects for both iOS and OS X that demonstrate important features such as shared libraries/frameworks, storyboards, Core Data models, and even hands-on debugger practice.

Xcode 4 represents an entirely redesigned version of Apples development suite. Despite reaching version 4.4 (in beta) during this writing, it has only been in developers hands for slightly more than a year. Unfortunately, this means it is a still a bit rough around the edges. We point out the issues where we encounter them, but dont be shy about filing bug reports with Apple if features dont quite work as anticipated. With the help of the OS X/iOS community, Xcode is being improved and enhanced rapidly. Each new release brings more consistency and reliability to the product.
