Hands-On Swift 5 Microservices Development. Build microservices for mobile and web applications using Swift 5 and Vapor 4

The capabilities of the Swift programming language are extended to server-side development using popular frameworks such as Vapor. This enables Swift programmers to implement the microservices approach to design scalable and easy-to-maintain architecture for iOS, macOS, iPadOS, and watchOS applications.This book is a complete guide to building microservices for iOS applications. You’ll start by examining Swift and Vapor as backend technologies and compare them to their alternatives. The book then covers the concept of microservices to help you get started with developing your first microservice. Throughout this book, you’ll work on a case study of writing an e-commerce backend as a microservice application. You’ll understand each microservice as it is broken down into details and written out as code throughout the book. You’ll also become familiar with various aspects of server-side development such as scalability, database options, and information flow for microservices that are unwrapped in the process. As you advance, you’ll get to grips with microservices testing and see how it is different from testing a monolith application. Along the way, you’ll explore tools such as Docker, Postman, and Amazon Web Services.By the end of the book, you’ll be able to build a ready-to-deploy application that can be used as a base for future applications.

Swift Functional Programming. Ease the creation, testing, and maintenance of Swift codes - Second Edition

Dr. Fatih Nayebi

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
