Web Development with Swift (iOS/macOS): From Basics to Deployment

Swift has long ceased to be exclusively a language for mobile applications. With the advent of the Vapor framework, it has become a powerful tool for creating server-side solutions, websites, and APIs. The book "Web Development with Swift (iOS/macOS): From Basics to Deployment" is a practical guide that will take you from your first lines of server code to launching a full-fledged web application into production.

The book is intended for developers already familiar with the basics of Swift (variables, functions, classes) but with no experience in web programming. If you are an iOS/macOS developer looking to expand your skills towards backend development or are simply interested in server-side Swift, this book is for you.

What you will learn:

• Vapor 4 Basics: installation, project structure, routing, and middleware.
• Working with Databases: Fluent ORM, migrations, models, table relationships (SQLite, PostgreSQL).
• Creating REST APIs: request handling, JSON, authentication and authorization (JWT, sessions).
• Leaf Templating Engine: dynamic HTML pages, forms, server-side data rendering.
• WebSockets and Real-Time: chats, notifications, live updates.
• Testing and Debugging: unit tests, endpoint testing, logging.
• Deployment: server setup (Linux/macOS), Docker, Vapor Cloud, Heroku, CI/CD.

Why is this book useful?

Unlike scattered tutorials, the book provides a complete picture. You will not only learn to write code but also understand the architecture of server applications: how to organize a project, how to handle errors, and how to scale. Each chapter contains code examples, exercises, and links to a repository with a ready-made project.

Special attention is paid to typical problems iOS developers face when transitioning to the server: working with asynchrony (EventLoopFuture), memory management, and differences in Foundation on the server and client. The book will help you avoid the pitfalls that beginners often encounter.

Who this book is for:

• iOS/macOS developers wanting to master backend development with Swift.
• Students and junior developers learning server-side technologies.
• Anyone who wants to create full-fledged web applications without switching languages.

By the end of the book, you will create and deploy your own application on the internet — for example, a blog, a bulletin board, or a task management system. You will gain not only theory but also a ready-made template for future projects.
