If you want in-depth knowledge of some of the most sophisticated elements of Swift development including protocol extensions, error-handling, design patterns, and concurrency, Mastering Swift 2 gives you guidance on how to use and apply them in your own projects. What You Will Learn Dive into the core components of Swift 2 including operators, collections, control flow, and functions Create and use classes, structures, and enums including object-oriented topics such as inheritance, protocols, and extensions Develop a practical understanding of subscripts, optionals, and closures Learn how to use the new protocol extension and error handling features of Swift 2 Add concurrency to your applications using Grand Central Dispatch Master Objective-C interoperability with Mix and Match Access network resources using Swift Implement various standard design patterns in the Swift languageIn Detail At their Worldwide Developer's conference (WWDC) in 2015, Apple announced Swift 2, a major update to the innovative programming language they first unveiled to the world the year before. Swift 2 features exciting enhancements to the original iteration of Swift, acting, as Apple put it themselves as?a successor to the C and Objective-C languages.? - This book demonstrates how to get the most from these new features, and gives you the skills and knowledge you need to develop dynamic iOS and OS X applications. Learn how to harness the newest features of Swift 2 todevelop advanced applications on a wide range of platforms with this cutting-edge development guide. Exploring and demonstrating how to tackle advanced topics such as Objective-C interoperability, ARC, closures, and concurrency, you'll develop your Swift expertise and become even more fluent in this vital and innovative language. With examples that demonstrate how to put the concepts into practice, and design patterns and best practices, you'll be writing better iOS and OSX applications in with a new level of sophistication and control. Style and approach This book takes an example-based approach where each concept covered is supported by example code to not only give you a good understanding of the concept, but also to demonstrate how to properly implement it.;Cover ; Copyright; Credits; About the Author; About the Reviewer; www.PacktPub.com; Table of Contents; Preface; Chapter 1: Taking the First Steps with Swift ; What is Swift?; Swift features; Playgrounds; Getting started with Playgrounds; iOS and OS X Playgrounds; Showing images in a Playground; Creating and displaying graphs in Playgrounds; What Playgrounds are not; Swift language syntax; Comments; Semicolons; Parentheses; Curly braces; An assignment operator does not return a value; Spaces are optional in conditional and assignment statements; Hello World; Summary
