Overview of this book

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.

Requirements for the sample code

When we develop applications, we usually have a set of requirements that we need to work towards. Our sample project in this chapter and the next are no different. The following is a list of requirements for the vehicle types that we will be creating:

  • We will have three categories of vehicle: sea, land, and air. A vehicle can be a member of multiple categories.
  • Vehicles may move or attack when they are on a tile that matches any of the categories they are in.
  • Vehicles will be unable to move to or attack on a tile that does not match any of the categories they are in.
  • When a vehicle's hit points reach zero, the vehicle will be considered incapacitated. We will need to keep all active vehicles in a single array that we can loop through.

For our design in this chapter, we will be demonstrating the design with only a few vehicles, but we know...
