Server-Side Swift

Introduction

The book "Server-Side Swift" by Tim Condon is a practical guide to building server applications in Swift. Published in 2020 (424 pages), it became one of the few comprehensive publications dedicated to the Swift ecosystem outside of mobile and desktop development. The book is aimed at developers already familiar with the basics of Swift and offers a sequential path from environment setup to deploying a finished backend.

What the book is about

The publication covers all key aspects of server-side development in Swift. The main focus is on the Vapor framework — the most popular tool for creating web services in Swift. However, the author also touches on alternatives (Kitura, Perfect) and general principles of building REST APIs, working with databases, authentication, and testing.

Chapter contents

• Development environment setup (macOS, Linux, Docker)
• Vapor basics: routing, controllers, middleware
• Working with Fluent ORM and databases (PostgreSQL, SQLite, MySQL)
• Creating RESTful APIs with JSON serialization
• Authentication (JWT, sessions, OAuth)
• WebSockets and real-time
• Testing (Unit, Integration, Performance)
• Deployment on servers (Heroku, AWS, DigitalOcean)
• Migrations, logging, error handling

Who this book is for

The book is intended for iOS/macOS developers who want to expand their skills and start writing server-side code in a familiar language. It will also be useful for web developers interested in Swift, and students learning modern approaches to backend development. It is assumed that the reader already knows Swift syntax and basic OOP concepts.

What the reader will learn

• How to set up a server environment for Swift (including Docker containers)
• Creating a full-fledged REST API using Vapor 4
• Working with databases via Fluent ORM (models, migrations, queries)
• Implementing authentication and authorization (JWT, sessions, social networks)
• Error handling, logging, and monitoring
• Testing server applications (XCTest, Postman)
• Deploying to cloud platforms (Heroku, AWS)
• Using WebSockets for real-time functionality

Strengths

The main advantage of the book is its practical focus. Each chapter contains code examples that can be immediately run and modified. The author not only explains theory but guides the reader from a simple "Hello, World" to a complex multi-module project. Special mention should be made of the quality description of Fluent ORM — one of the most confusing topics in Vapor. The book also pays attention to security (SQL injection, XSS, CSRF) and best practices for code organization.

Another plus is its relevance. Despite being from 2020, the material remains relevant for Vapor 4 (stable version as of 2025). All examples are tested and work. The book is written in a lively style, without excessive academicism.

Who it is recommended for

We recommend this book to anyone who wants to use Swift beyond iOS. If you already write mobile applications and want to create your own backend without switching to JavaScript or Python — this is an ideal start. The book is also suitable for team leads who are considering Swift as an alternative for microservices in the Apple ecosystem.

On the PythonLib website, you can find additional materials on Swift, Vapor, and related technologies. The book "Server-Side Swift" will be an excellent addition to your library if you are striving for full-stack development in Swift.
