Who this book is for

This book is for SwiftUI developers who already understand the basics of SwiftData and now want to build real applications with it.

Developers who want to understand ModelContext, ModelContainer, and change tracking

iOS developers building apps with relationships, queries, migrations, and CloudKit

Teams that need practical strategies for testing, debugging, and performance

Developers who want to move beyond simple demos and learn real-world SwiftData architecture

You’ll learn how SwiftData behaves behind the scenes, how to structure your models, how to query data effectively, how to debug the underlying SQLite store, and how to design apps that remain maintainable as your data layer grows.

What you’ll get

A practical, experience-driven guide to building SwiftData applications with confidence. Instead of treating SwiftData as a magic persistence layer, this book helps you understand what is happening underneath so you can make better architectural decisions.

Your purchase includes the digital ebook and future updates as SwiftData continues to evolve.
