Please note that the XCode 3 screencast is no longer for sale.
Xcode is the development environment used to create iPhone and Mac applications. There’s a lot you can do with Xcode, and it’s easy to get distracted by all the knobs and levers. But you’re using Xcode for one simple reason: You want to build iPhone or Mac applications as quickly as possible. Whether you’re a new iPhone developer seeing Xcode for the first time, or wish you were more familiar with the shortcuts, these screencasts will make you a more productive (and happier!) Xcode programmer.
