Swift essentials : discover how to build iOS and watchOS applications in Swift 2 using Xcode / Dr Alex Blewitt.

Includes index.

Description based on online resource; title from cover page (Safari, viewed February 5, 2016).

A fast-paced guide that provides an overview of Swift programming and then walks you through how to write iOS applications in detail. Progress through chapters on custom views, networking and parsing, and build a complete application as a Git repository, all by using Swift as the core language.

This practical guide will give you hands-on experience with all the features of Swift programming. Following the practical examples in the book will help you successfully create your own iOS applications.

No prior iOS programming experience is assumed; however, having some experience with any programming language will be beneficial.
