Overview of this book

macOS continues to lead the way in desktop operating systems, with its tight integration across the Apple ecosystem of platforms and devices. With this book, you will get an in-depth knowledge of working on macOS, enabling you to unleash the full potential of the latest version using Swift 3 to build applications. This book will help you broaden your horizons by taking your programming skills to next level. The initial chapters will show you all about the environment that surrounds a developer at the start of a project. It introduces you to the new features that Swift 3 and Xcode 8 offers and also covers the common design patterns that you need to know for planning anything more than trivial projects. You will then learn the advanced Swift programming concepts, including memory management, generics, protocol orientated and functional programming and with this knowledge you will be able to tackle the next several chapters that deal with Apple’s own Cocoa frameworks. It also covers AppKit, Foundation, and Core Data in detail which is a part of the Cocoa umbrella framework. The rest of the book will cover the challenges posed by asynchronous programming, error handling, debugging, and many other areas that are an indispensable part of producing software in a professional environment. By the end of this book, you will be well acquainted with Swift, Cocoa, and AppKit, as well as a plethora of other essential tools, and you will be ready to tackle much more complex and advanced software projects.

Chapter 11. Core Animation

It's a funny thing how mobile computing, meaning chiefly smart phones, has led the way in animated user interfaces. The restricted space in which the mobile developer must build an interface between an app and the user has meant that animation has developed an essential role in providing the user with cues as to how to engage with apps that might show three or four buttons, where a desktop program would have a dozen or more.

Arguably, desktop computing has not really kept up with the mobile, and even the HTML 5-based browser experience. In many, if not most, apps, there is little in terms of animation beyond the drawing of a focus ring, highlighted-on-click buttons, and a few other system-provided flourishes.

Although things are changing slowly, there is still a massive amount of untapped potential when it comes to animating the UI in subtle but engaging ways. It is this that we will address in this chapter.
