Bring the power of functional programming to Swift to develop clean, smart, scalable and reliable applications.
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
What You Will Learn
- Understand what functional programming is and why it matters
- Understand custom operators, function composition, currying, recursion, and memoization
- Explore algebraic data types, pattern matching, generics, associated type protocols, and type erasure
- Get acquainted with higher-kinded types and higher-order functions using practical examples
- Get familiar with functional and non-functional ways to deal with optionals
- Make use of functional data structures such as semigroup, monoid, binary search tree, linked list, stack, and lazy list
- Understand the importance of immutability, copy constructors, and lenses
- Develop a backend API with Vapor
- Create an iOS app by combining FP, OOP, FRP, and POP paradigms
