Swift (iOS/macOS): Tips and Best Practices

The book "Swift (iOS/macOS): Tips and Best Practices" is a practical guide for developers who want to write clean, efficient, and maintainable code in Swift. Unlike basic tutorials, this book focuses on real-world scenarios and professional techniques that will help you level up your mastery.

What is this book about?

The author has compiled years of experience developing for iOS and macOS, structuring it into specific tips and ready-made solutions. You will learn:

• How to design application architecture (MVVM, Coordinator, Redux) and choose the right pattern for a specific task.
• Secrets of memory management and handling reference cycles in Swift.
• Performance optimization techniques: from image loading to working with Core Data and Networking.
• How to write testable code and implement unit testing in legacy projects.
• Best practices for SwiftUI and Combine: view composition, state management, error handling.
• Nuances of working with Grand Central Dispatch, Swift Concurrency (async/await), and the Actor model.
• Tips on code review, documentation, and organizing a codebase within a team.

Who is this book for?

• Junior developers who have mastered the basics of Swift and want to understand how to write production-level code.
• Middle developers looking to fill gaps in architecture and performance.
• Senior developers seeking new approaches to solving complex problems and refactoring.
• Anyone transitioning from Objective-C to Swift or from UIKit to SwiftUI.

What will you gain after reading?

• A clear understanding of what decisions to make at each stage of development.
• A set of proven techniques that will save hours of debugging.
• Confidence in choosing tools: when to use struct vs. class; where to apply value semantics.
• Ready-made code templates for common tasks (networking, caching, multithreading).
• The ability to conduct code reviews and spot potential issues before they reach production.

The book is written in a lively style, with examples from real projects. Each tip is accompanied by code and an explanation of why it works. This is not a reference guide — it is a navigator through the best practices of Swift development that will remain on your shelf as a desk reference.

Perfect for those who want to write code they are proud of and build apps they are not ashamed to show to colleagues.
