Mastering Swift 5 - Fifth Edition

By: Jon Hoffman

Overview of this book

Over the years, the Mastering Swift book has established itself amongst developers as a popular choice as an in-depth and practical guide to the Swift programming language. The latest edition is fully updated and revised to cover the new version: Swift 5. Inside this book, you'll find the key features of Swift 5 easily explained with complete sets of examples. From the basics of the language to popular features such as concurrency, generics, and memory management, this definitive guide will help you develop your expertise and mastery of the Swift language. Mastering Swift 5, Fifth Edition will give you an in-depth knowledge of some of the most sophisticated elements in Swift development, including protocol extensions, error handling, and closures. It will guide you on how to use and apply them in your own projects. Later, you'll see how to leverage the power of protocol-oriented programming to write flexible and easier-to-manage code. You will also see how to add the copy-on-write feature to your custom value types and how to avoid memory management issues caused by strong reference cycles.

Summary

Design patterns are solutions to software design problems that we tend to see over and over again in real-world application design. These patterns are designed to help us create reusable and flexible code. Design patterns can also make the code easier to read and understand for other developers and also for ourselves when we look back at the code months/years later.

If we look at the examples in this chapter carefully, we will notice that one of the backbones of design patterns is the protocol. Almost all design patterns (the singleton design pattern is an exception) use protocols to help us create very flexible and reusable code.

If this was the first time that you really looked at design patterns, you probably noticed some strategies that you have used in the past in your own code. This is expected when experienced developers are first introduced to design patterns....
