Swift (iOS/macOS) and Microservices: From Mobile App to Distributed System

The book "Swift (iOS/macOS) and Microservices" is a practical guide for developers who want to master building server-side applications in Swift. If you're tired of "fat" clients and want to learn how to build reliable, scalable distributed systems using the familiar syntax and Apple ecosystem, this book is for you.

The author systematically guides the reader from the basics of server-side development to building a full-fledged microservice architecture. You will learn how to use the Vapor framework to create REST APIs, work with databases, organize inter-service communication, and deploy ready-made solutions to the cloud.

What you will learn from the book:

• How to set up a development environment for server-side Swift and create your first microservice with Vapor
• Basics of working with Fluent ORM: migrations, models, database queries
• Architectural patterns for microservices: API Gateway, Service Discovery, Circuit Breaker
• Asynchronous programming with Async/Await and the Combine framework
• Authentication and authorization: JWT, OAuth2, API security
• Docker containerization and microservice orchestration
• Logging, monitoring, and debugging distributed systems
• Testing: unit tests, integration tests, API testing
• Inter-service communication via gRPC and message queues

Who this book is for:

• iOS and macOS developers looking to expand their stack and learn backend development
• Full-stack developers who want to use Swift on the server side
• Team Leads and architects planning to implement microservice architecture in Swift projects
• CTOs and technical managers evaluating Swift's capabilities for building distributed systems

For comfortable reading, a solid grasp of Swift and a basic understanding of networking are sufficient. Knowledge of other programming languages is not required — all examples are written exclusively in Swift.

The book contains many ready-to-use code examples, practical exercises, and design recommendations. You won't just study theory; you'll be able to immediately apply what you've learned in practice by creating your first microservice in Swift.

Join the community of developers who don't limit themselves to mobile development but build full-fledged distributed systems in a language you already know and love.
