Starting with simple apps to more complex ones, the book will show how to master iOS development with Swift.
This book will show how to implement seven different apps, from utilities to games in 3D.
The book doesn't show only the features of the language, but also how to write clean code, easy to extend and to mantain.
All the code of the apps is available on Github, licensed as Open Source, so that you can use it in your apps.
In the later examples in this book, the author shows you how to import and use CocoaPods. I'm giving this book four stars because it seems obvious to me that the author is an accomplished coder and his example programs are well-structured.
The apps you build in this book are not trivial. The author stresses code reusability and flexibility and lays out his programs accordingly. He frequently uses extensions to good effect. The author also doesn't give you simplistic apps and then promise you that you're ready for the App Store. On page 107 he writes that creating an app is not "straightforward." His realism is refreshing.
Swift By Example takes the reader through the Swift programming language by building easy to complex apps using Swift. Just look on stackoverflow and github and you will see the growing use of the swift programming language. I particularly loved building the Flappy Bird clone, which shows you that you can get anything done in swift. Must buy!
