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

Functions and Closures

In the previous chapter, we had an overview of Functional Programming (FP) and the Swift programming language. It introduced some of the key concepts of functions. As functions are the fundamental building blocks in FP, this chapter dives deeper into the subject and explains all the aspects related to the definition and usage of functions in Swift and FP, together with coding examples.

This chapter starts with the Swift function and method syntax, continues with other related topics such as function types and tuples, and finally concludes with FP topics such as first-class functions, higher-order functions, function composition, closures, currying, recursion, and memoization.

This chapter will cover the following topics by coding examples:

  • General syntax of functions
  • Defining and using function parameters
  • Setting internal and external parameters
  • Setting default parameter values
  • Defining and...
