Hands-On Swift 5 Microservices Development

Overview of this book

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.

Technical requirements

This section covers what you will need to have running on your machine so that you can write this microservice. The following components will need to be installed:

  • Vapor Toolbox
  • Swift 5.2+
  • Xcode 11+
  • macOS/Linux

We are also assuming that you have worked through the previous chapters and know how to write a Vapor microservice. Going through the creation of this microservice will focus on the new elements, not what was covered in Chapter 7, Writing the User Service. All code in this chapter will run on macOS and Linux alike.
