Do you want to program your own apps for iPhone, iPad, and iPod touch? Perhaps also for the Apple Watch or Apple TV? Are you even interested in developing and selling professional Apple apps? Then Christian Bleske offers you an easy entry point with this book. He introduces you to the Swift programming language (version 3) in a clear and understandable way, familiarizing you with app development and the Xcode development environment. In a small introductory project, you will program your first application step by step and quickly learn what is important in app development. Building on that, you will establish a solid foundation in Swift programming, including debugging and troubleshooting. Additionally, you will receive a systematic introduction to the many facets of app development for Apple's operating systems iOS, tvOS, and watchOS.
