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.

Understanding Foundation Kit


The Foundation Kit framework that comes with Cocoa (officially it's got the Kit appended to it, but not many people bother) provides us with a number of basic utility classes, which were originally written to extend the Objective C programming language. These include strings, arrays, sets, dictionaries, and dates, for example.

Some of the more basic classes are, strictly speaking, no longer needed for Swift development, since Swift already provides support for strings, text, and collections such as dictionaries and arrays. However, we will see later that they can often be of use to us. Foundation is baked into the core of Cocoa, so we will need to make use of most of what it has to offer.

Then there are a larger number of classes that go way beyond basic data types and structures, such as those providing us with classes for network connectivity, notifications, threading, user defaults, and many others.

In addition to its classes, Foundation also defines a number...
