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.

Installing Vapor

Now it is time to install Vapor onto your machine. Let's make sure that you have all you need. It is essential that you use an up-to-date system in order for Swift and Vapor to function correctly. I am assuming that you are working on a macOS computer for this book. Everything server-related should also work fine on a Linux machine, though.

Prerequisites

Make sure that you have the following setup already in place:

  • macOS Mojave or newer
  • Xcode 10.2 or newer
  • Homebrew: If you have not installed Homebrew, then go ahead and install it as described here: https://brew.sh/
You could use Linux (Ubuntu) as well; this book assumes you are using macOS, though. The only difference is that Xcode does not exist for...
