Build fast and powerful applications by harnessing the power of protocol-oriented programming in Swift 4

Key Features

  • Leverage the power of protocol-oriented programming in your applications and learn from real-world use cases
  • Create a flexible code base with protocols and protocol extensions
  • Leverage the power of generics in Swift 4 to create very flexible frameworks

Book Description

Swift has become the number one language used in iOS and macOS development. The Swift standard library is developed using protocol-oriented programming techniques, generics, and first-class value semantics; therefore, every Swift developer should understand these powerful concepts and how to take advantage of them in their application design.

This book will help you understand the differences between object-oriented programming and protocol-oriented programming. It will demonstrate how to work with protocol-oriented programming using real-world use cases. You will gain a solid knowledge of the various types that can be used in Swift and the differences between value and reference types. You will be taught how protocol-oriented programming techniques can be used to develop very flexible and easy-to-maintain code.

By the end of the book, you will have a thorough understanding of protocol-oriented programming and how to utilize it to build powerful and practical applications.

What you will learn

  • Understand the differences between object-oriented programming and protocol-oriented programming
  • Explore the different types that Swift offers and what pitfalls to avoid
  • Delve into generics and generic programming
  • Learn how to implement Copy-On-Write within your custom types
  • Implement several design patterns in a protocol-oriented way
  • Design applications by prioritizing the protocol first and the implementation types second
