Swift (iOS/macOS) Application Architecture

Creating a high-quality iOS or macOS application is not just about knowing Swift syntax and UIKit. The real engineering challenge is to design code that is flexible, testable, and easy to maintain. The book "Swift (iOS/macOS) Application Architecture" is a practical guide to selecting and implementing architectural patterns that will help you write clean, scalable code.

Who is this book for?

• iOS/macOS developers who have encountered "spaghetti code" problems in ViewController.
• Junior and Middle specialists looking to systematize their knowledge of application design.
• Team Leads seeking optimal approaches for organizing team work on a large project.

What you will learn:

• The basic principles of SOLID and their application in the Apple ecosystem.
• A detailed breakdown of classic patterns: MVC, MVP, MVVM — with examples in Swift 5.9+.
• Modern approaches: Coordinator (navigation), VIPER (for complex screens), and Clean Architecture.
• How to combine SwiftUI and UIKit within a single architecture.
• Organizing the data layer: Repository, Service Locator, Dependency Injection.
• Testing: unit and UI tests with different architectural solutions.
• Refactoring: step-by-step recipes for turning a poorly designed project into a well-structured one.

Edition features:

• All code examples are up-to-date for Swift 5.9+ and Xcode 15+.
• Real-world cases from the author's practice, including applications with multithreading and network requests.
• Comparison tables: when to choose MVVM and when to choose VIPER.
• Ready-made boilerplate templates for quickly starting a new project.

This book is not about abstract theory — it is about making architectural decisions that will save you hours of debugging and rewriting code. After reading it, you will be able to confidently design applications of any scale: from a simple timer to a corporate messenger or video editor.
