Swift (iOS/macOS) Application Architecture. Patterns and Practices

The book "Architecture of Swift (iOS/macOS) Applications" is a practical guide to building flexible, scalable, and easily maintainable architecture for applications on Apple platforms. The author, Alexey Voronov, a senior iOS developer with 8 years of experience, shares proven approaches and real-world cases from commercial development.

What the book is about:

• Detailed analysis of classic architectural patterns: MVC, MVP, MVVM, VIPER, Clean Swift (VIP).
• Comparative analysis of patterns with examples in Swift: when and which one to choose.
• SOLID principles in the context of iOS/macOS development.
• Working with dependencies: DI containers, Service Locator, factories.
• Architecture testing: unit and integration tests, mock objects.
• Asynchrony and reactive programming: Combine, async/await, RxSwift.
• Code organization for macOS applications (differences from iOS).
• Refactoring legacy code: step-by-step transition from Massive View Controller to clean architecture.

Who this book is for:

• Junior and Middle iOS/macOS developers who want to level up.
• Team Leads and architects looking for a systematic approach to design.
• Developers transitioning from UIKit to SwiftUI who need to understand architectural principles.
• Anyone who has encountered the problem of "spaghetti code" and wants to learn how to write clean, testable code.

What you will learn and be able to do after reading:

• Consciously choose an architectural pattern for a specific task.
• Design application layers: Presentation, Domain, Data.
• Implement navigation and routing without tight coupling.
• Write unit tests for ViewModel, Interactor, Presenter.
• Avoid common mistakes when working with Core Data, Networking, and UI.
• Build architecture that easily scales and adapts to changing requirements.

The book contains over 50 code examples, component interaction diagrams, and ready-made templates for Xcode. All examples are written in current versions of Swift (5.9+) and are compatible with iOS 17+ and macOS 14+.

This is not just a collection of patterns, but a comprehensive guide to architectural thinking that will remain relevant regardless of the release of new Apple frameworks and technologies.
