Who This Book Is For

This book is ideal for those who want to learn to develop app in Swift, starting the right way. Whether you are an expert Objective-C programmer or are new to this platform, you''ll quickly grasp the code of real world apps, and discover how to use Swift effectively. Prior experience in development for Apple devices would be helpful, but is not mandatory.

What You Will Learn

Create a server in Swift to deliver JSON data to an iOS appTake advantage of Cocoapods to use third-party librariesUse a clean and effective architecture to decrease complexity and speed up developmentTake advantage of the most useful parts of the iOS SDKBuild games with SpriteKit and SceneKitDevelop an app running on the cloud to act as an API server for your client''s apps

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.

Start building your very own mobile apps with this comprehensive introduction to Swift and object-oriented programming

Book Description

Swift Language is now more powerful than ever; it has introduced new ways to solve old problems and has gone on to become one of the fastest growing popular languages. It is now a de-facto choice for iOS developers and it powers most of the newly released and popular apps. This practical guide will help you to begin your journey with Swift programming through learning how to build iOS apps.You will learn all about basic variables, if clauses, functions, loops, and other core concepts; then structures, classes, and inheritance will be discussed. Next, you’ll dive into developing a weather app that consumes data from the internet and presents information to the user. The final project is more complex, involving creating an Instagram like app that integrates different external libraries. The app also uses CocoaPods as its package dependency manager, to give you a cutting-edge tool to add to your skillset. By the end of the book, you will have learned how to model real-world apps in Swift.
