Overview of this book

Swift is a multi-paradigm programming language enabling you to tackle different problems in various ways. Understanding each paradigm and knowing when and how to utilize and combine them can lead to a better code base. Functional programming (FP) is an important paradigm that empowers us with declarative development and makes applications more suitable for testing, as well as performant and elegant. This book aims to simplify the FP paradigms, making them easily understandable and usable, by showing you how to solve many of your day-to-day development problems using Swift FP. It starts with the basics of FP, and you will go through all the core concepts of Swift and the building blocks of FP. You will also go through important aspects, such as function composition and currying, custom operator definition, monads, functors, applicative functors,memoization, lenses, algebraic data types, type erasure, functional data structures, functional reactive programming (FRP), and protocol-oriented programming(POP). You will then learn to combine those techniques to develop a fully functional iOS application from scratch

Enumerations and Pattern Matching

In Chapter 1, Getting Started with Functional Programming in Swift, we were introduced to enumerations briefly. In the previous chapter we got familiar with types and we learned that enums are sum types.

In this chapter, we will cover enumerations and algebraic data types in detail. Also, we will explore patterns and pattern matching in Swift.

This chapter will cover the following topics with coding examples:

  • Defining enumerations
  • Associated values
  • Raw values
  • Nesting and containing enumerations
  • Using enumerations
  • Algebraic data types
  • Patterns and pattern matching
