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.

Using abstract and concrete implementations

When writing software, we are often faced with making decisions about how concrete our code is. For example, if you are tasked with writing a chat application, you need to have answers to the following questions:

  • Is the chat between two people or can it be more than two?
  • What kind of content is being exchanged? Text, image, video, audio, or a combination? Maybe all of it?
  • How long of a chat history should be stored?

You can probably easily spot further questions that can come up. In a well-planned and thoroughly thought-through project, there would be an answer to all these questions. However, in almost all the projects that I have seen, many of these questions are overlooked, and well-intended projects still face these questions. Some of these questions are also too technical for the people who tasked you with this. However, let&apos...
