Mastering macOS Programming.

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.

What Core Data is, and isn't

For the moment, we'll just talk very briefly about why we'd even need Core Data.

Core Data basically offers you a way to avoid reinventing the wheel every time you need to store, manage, and present data. We're all developers, we all need data management, and to a large extent (and I do mean large), Core Data saves us a ton of code writing, testing, and debugging, by exposing to us ready-rolled solutions for many of the tasks surrounding data.

Core Data is not a database. It contains abstractions of dealing with databases, and very efficient ones at that, but it is not a database as such, and it is much more than a wrapper around SQLite (for example). However, a lot of the concepts and nomenclature around Core Data are borrowed from the database world.

Core Data allows us to quickly, reliably, and efficiently deal with data, in a way that is consistent across apps and platforms. If you ever walk into a job and take over an app on day one, with nothing more than...
