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.

Creational patterns

Creational patterns are design patterns that deal with how an object is created. There are two basic ideas behind creational patterns. The first is the encapsulation of the knowledge of which concrete types should be created, and the second involves hiding how instances of these types are created.

There are five well-known patterns that are a part of the creational pattern category. They are as follows:

  • Abstract factory pattern: This provides an interface for creating related objects without specifying the concrete type
  • Builder pattern: This separates the construction of a complex object from its representation so that the same process can be used to create similar types
  • Factory method pattern: This creates objects without exposing the underlying logic of how the object (or the type of object) is created
  • Prototype pattern: This creates an object by cloning...
