Swift 4 Protocol-Oriented Programming: Bring predictability, performance, and productivity to your Swift applications, 3rd Edition

• Leverage the power of protocol-oriented programming in your applications and learn from real world use cases
• Create a flexible codebase with protocols and protocol extensions
• Increase the overall productivity and performance of applications with protocol-oriented programming

One of the most important additions to the new features and capabilities of the Swift programming language was an overhaul of protocols. Protocol-oriented programming and first-class value semantics have now become two incredibly powerful concepts at the heart of Swift's design. The Swift standard library is developed using Protocol-Oriented programming techniques so understanding what Protocol-Oriented programming is all about will help you understand how Swift standard library.

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 different 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 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, practical applications.
