In Detail
Swift is no longer the unripe language it was when launched by Apple at WWDC14, now it's a powerful and ready-for-production programming language that has empowered most new released apps.
Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and really flexible.
Swift 2 is more powerful than ever; it introduces new ways to solve old problems, more robust error handling, and a new programming paradigm that favours composition over inheritance.
Swift 2 by Example is a fast-paced, practical guide to help you learn how to develop iOS apps using Swift. Through the development of seven different iOS apps and one server app, you'll find out how to use either the right feature of the language or the right tool to solve a given problem.
We begin by introducing you to the latest features of Swift 2, further kick-starting your app development journey by building a guessing game app, followed by a memory game. It doesn't end there, with a few more apps in store for you: a to-do list, a beautiful weather app, two games: Flappy Swift and Cube Runner, and finally an ecommerce app to top everything off.
By the end of the book, you'll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.
Style and approach
These easy-to-follow tutorials show you how to build real-world apps. The difficulty and complexity level increases chapter by chapter. Each chapter is dedicated to build a new app, beginning from a basic and unstyled app through to a full 3D game. The last two chapters show you how to build a complete client-server ecommerce app right from scratch.

About the Author
Giordano Scalzo is a developer with 20 years of programming experience, since the days of the ZXSpectrum.
He has worked in C++, Java, .Net, Ruby, Python, and in so many other programming languages he has forgotten the names.
After years of backend development, over the past 5 years Giordano has developed extensively for iOS, releasing more than 20 apps—apps that he wrote for clients, enterprise applications, or on his own.
Currently, he is a contractor in London, where—through his company, Effective Code Ltd, http://effectivecode.co.uk—he delivers code for iOS, aiming at quality and reliability.
In his spare time, when he is not crafting retro game clones for iOS, he writes his thoughts at http://giordanoscalzo.com.
I'd like to thank my better half, Valentina, who lovingly supports me in everything I do: without you, none of this would have been possible.
Thanks to my bright future, Mattia and Luca, for giving me lots of smiles and hugs when I needed them.
Finally, my gratitude goes to my Mum and Dad, who gave my curiosity the right push, along with the support to follow my passions, which began the day they bought me a ZXSpectrum.

Preface
The introduction of Swift during WWDC 2014 surprised the whole community of iOS developers, who were waiting to be introduced to the new API from iOS 8, not to be transformed into beginners.
Besides the surprise, most of them understood that this would have been 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 rough first impact of Objective-C, started to be attracted by Swift, which—with its friendly syntax—was less intimidating.
After a year, Swift 2.0 has proven to be a huge improvement over the first version, enriched by a lot of new features and strengthened by its use in thousands of new apps. It is finally ready for production!
In WWDC 2015, Apple made another surprising announcement: Swift will be open source and there will be versions for different operating systems, beginning with Linux and Windows. This opens up a whole new scenario, where it will be possible to implement both client and the server apps with the same language.
This book will introduce you the world of app development using the new features in Swift 2, and it will show you how to build Linux apps in Swift in order to create server counterparts of your mobile apps.
Through simple step-by-step chapters, the book will teach you how to build both utility and game apps; while building them, you'll learn the basics of Swift and iOS.
What this book covers
Chapter 1, Welcome to the World of Swift, introduces the Swift syntax and the most important features provided by the language.
Chapter 2, Building a Guess the Number App, introduces Xcode, its project file, and the different editors required to build an app; a simple game app will be created to demonstrate these.
Chapter 3, A Memory Game in Swift, shows the creation of a complete game app, with images and animations, without using any Game framework but with only the fundamental iOS libraries.
Chapter 4, A TodoList App in Swift, teaches you how to create a real-world utility app, handling the library dependencies with Cocoapods.
Chapter 5, A Pretty Weather App, shows you how to create a nice looking app that retrieves data from third-party servers.
Chapter 6, Flappy Swift, covers SpriteKit, the 2D iOS game engine.
Chapter 7, Polishing Flappy Swift, completes the game, adding Game Center support and various entertaining touches.
Chapter 8, Cube Runner, covers SceneKit and 3D programming, implementing a 3D endless runner with a space theme.
Chapter 9, Completing Cube Runner, finalizes the game and adds Game Center support.
Chapter 10, ASAP – an E-commerce App in Swift, implements an ecommerce app that uses local storage to store the products.
Chapter 11, ASAPServer, a Server in Swift, is a follow-up to the previous chapter, where we'll implement a backend server for Linux to handle the requests of the ASAP e-commerce app.
