What's new in iOS 8?
You might be familiar with Apple's mobile operating system, popularly known as iOS; the latest version of this operating system is iOS 8. This version has a lot of new additions over its predecessor, iOS 7. Some of the additions in this version are the introduction of the Swift programming language, loads of new API's, and most importantly, improvements in Sprite Kit and its peripheral frameworks.
In this book, we will be using the Swift programming language over Objective-C. Although, you can use Sprite Kit with either Objective-C or Swift, Swift offers much easier syntax, and has a simpler learning curve.
