Swift 2 By Example

By: Giordano Scalzo

Overview of this book

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.

Integrating with Game Center


Game Center can be defined as a social gaming network that offers multiplayer features. It was made available in iOS 4.1, and it has been updated with new gaming options ever since.

What Game Center provides

The features provided by Game Center are as follows:

  • Leaderboards: This is a shared database containing the scores of the players of the game. It allows them to add their personal results and compare them with the scores of other players.

  • Achievements: These are the goals defined inside the game that cause players to maintain interest in the game. Some examples of achievements can be Destroyed 50 Enemies, Run during the Night, and so on.

  • Multiplayer: This feature allows the developer to implement a networked game where players can compete with each other, either in real time or in a turn-based manner.

Incorporating Game Center in an app is a two-step project. First of all, we need to set up the app in iTunes Connect, enabling Game Center support and setting...
