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.

Structural design patterns

Structural design patterns describe how types can be combined to form larger structures. These larger structures can generally be easier to work with, and hide a lot of the complexity of the individual types. Most patterns in the structural pattern category involve connections between objects.

There are seven well-known patterns that are part of the structural design pattern type. These are as follows:

  • Adapter: This allows types with incompatible interfaces to work together
  • Bridge: This is used to separate the abstract elements of a type from the implementation, so the two can vary
  • Composite: This allows us to treat a group of objects as a single object
  • Decorator: This lets us add or override behavior in an existing method of an object
  • Facade: This provides a simplified interface for a larger and more complex body of code
  • Flyweight: This allows us to...
