Preface

The introduction of Swift during the WWDC 2014 surprised the entire community of iOS developers, who were waiting for the new API brought by iOS 8 and not to be transformed into beginners.

Besides the surprise, most of them understood that this would be a great opportunity to create a new world of libraries, patterns, best practices, and so on. On the other hand, communities of programmers in different languages who were intimidated by the first (and rough) impact of Objective-C started getting attracted by Swift, which was less intimidating given its friendly syntax.

Whether you are part of the first or second group, Swift by Example will introduce the world of app development to you. Through simple step-by-step chapters, this book will teach you how to build both utility and game apps and, while building them, you'll learn the basics of Swift and iOS.
