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.

Understanding Server-Side Swift

Swift is a very young language as it was just released in 2014. It was designed to be a language with an easy syntax but that is as powerful as C. In this chapter, you are going to learn why Swift is an excellent choice when it comes to developing server applications. Swift arrives as a fresh alternative to all current and established solutions.

This chapter will introduce you to the server side of Swift; the basic understanding of Swift itself is something you should be familiar with already. At first, you are going to look at Swift as a generic language and why it fits well into the server world. Afterward, we look at the performance Swift delivers compared to other web technologies. A review of the current state of Swift for servers and an introduction to the new features of Swift 5 will sum this chapter up.

The following topics will be covered...
