Interested in building apps? Your author has written a video- based online text to learn to program in the Swift language while also learning app programming development. The first three chapters are free. If you have a Mac you can download Apple's Xcode software and get started. Visit http://gallaugher.com/swift for more info. And if you like learning to code, encourage your university to adopt this product for a "flipped class." Students learn on their own through more than 100 video lectures and exercises, and spend classroom time on additional exercises that would be considered "homework" in a traditional class. It's never been easier for your school to offer an apps class, and if you're successful, maybe we'll profile your firm in a future version of this textbook!
