There are times when we would like to describe the implementations (methods, properties, and other requirements) of a type without actually providing any implementation. For this, we can use protocols.Protocols define a blueprint of methods, properties, and other requirements for a class or a structure. A class or a structure can then provide an implementation that conforms to those requirements. The class or structure that provides the implementation is said to conform to the protocol.Protocols are very important to the Swift language. The entire Swift standard library is based on them, and we will be looking at protocols and how to use them in Chapter 8, Using Protocols and Protocol Extensions, and Chapter 9, Protocol Oriented Design.

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.
