Swift Protocol-Oriented Programming - Fourth Edition

By: Jon Hoffman

Overview of this book

Protocol-oriented programming is an incredibly powerful concept at the heart of Swift's design. Swift's standard library was developed using POP techniques, generics, and first-class value semantics; therefore, it is important for every Swift developer to understand these core concepts and take advantage of them. The fourth edition of this book is improved and updated to the latest version of the Swift programming language. This book will help you understand what protocol-oriented programming is all about and how it is different from other programming paradigms such as object-oriented programming. This book covers topics such as generics, Copy-On-Write, extensions, and of course protocols. It also demonstrates how to use protocol-oriented programming techniques via real-world use cases. By the end of this book, you will know how to use protocol-oriented programming techniques to build powerful and practical applications.

Behavioral design patterns

Behavioral design patterns explain how types interact with each other. These patterns describe how different instances of types send messages to each other to make something happen.

There are nine well-known patterns that are part of the behavioral design pattern type. They are as follows:

  • Chain of responsibility: This is used to process a variety of requests, each of which may be delegated to a different handler.
  • Command: This creates objects that can encapsulate actions or parameters so that they can be invoked later or by a different component.
  • Iterator: This allows us to access the elements of an object sequentially without exposing the underlying structure.
  • Mediator: This is used to reduce coupling between types that communicate with each other.
  • Memento: This is used to capture the current state of an object and store it in a manner that can be...
