What you need for this book
To create and build the code presented here, you will need nothing more than Apple's Xcode software package, which you can download for free in the App Store, and a Mac to run it on. A number of other tools are introduced, such as the OS X Terminal app, which are already installed on your Mac.
Testing the code can be done using Xcode's Simulator app, though the reader is encouraged to run the apps on a physical device, which is important when testing production-ready code (and is much more fun).
