Swift Functional Programming

Getting Started with Functional Programming in Swift

Getting onto the functional programming bandwagon needs a mindset shift, and changing our mindset is not an easy task as it takes a considerable amount of time to master a paradigm such as object-oriented programming. It needs a thorough approach, but it should also be easy to grasp. That is why we will be introduced to functional programming paradigms first, before going through each topic in detail.

This chapter introduces immutability, pattern matching, closures, as well as pure, first-class, and higher-order functions with Swift. Although all the topics in this chapter will be covered in detail in upcoming chapters, it is going to be helpful to have a broad view of the paradigms. In addition, this chapter will introduce Swift, as it is important to know the basics of the language to utilize in functional programming.

The following topics will be covered, along with examples:

  • Why functional programming matters
  • What is FP?
  • Swift language basics
  • Immutability
  • First-class, higher-order, and pure functions
  • Optionals and pattern matching
  • Closures
  • Type aliasing

Key benefits

  • Written for the latest version of Swift, this is a comprehensive guide that introduces iOS, Web and macOS developers to the all-new world of functional programming that has so far been alien to them
  • Get familiar with using functional programming alongside existing OOP techniques so you can get the best of both worlds and develop clean, robust, and scalable code
  • Develop a case study on example backend API with Swift and Vapor Framework and an iOS application with Functional Programming, Protocol-Oriented Programming, Functional Reactive Programming, and Object-Oriented Programming techniques

Description

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

Who is this book for?

Meant for a reader who knows object-oriented programming, has some experience with Objective-C/Swift programming languages and wants to further enhance his skills with functional programming techniques with Swift 3.x.

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

This is feedback more than a review. If you want people to purchase your book you might take the time to make your sample more than credits and table of contents. I won’t buy a book where I can’t even sample the author’s writing style while explaining a complex topic.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
