Summary

This book covers advanced topics in Swift programming. If you have already read Apple's The Swift Programming Language and want to explore more about the language, this book is for you! Swift is great for systems programming, yet it can also be used to write high-level code. In this book, we will examine high-level abstractions such as generics and protocols, and we will also delve into low-level topics such as wrapping C code and the internal implementation of strings. This book will help you further complete your knowledge system and take you from a beginner or intermediate level in Swift through to becoming an advanced Swift developer.

Editor's review

Advanced Swift is not a beginner's guide, but a deep technical work intended to help developers move from 'knowing how to use Swift' to 'mastering Swift.' The author, Chris Eidhof, one of the core contributors to the Swift community, systematically analyzes the design philosophy and advanced features of the Swift language through his deep understanding of its features and extensive practical experience.

The greatest value of this book lies in its path of exploring 'knowing why it is so.' It does not stop at the level of syntax and API usage, but delves into core concepts such as the Swift type system, generic programming, functional programming paradigms, protocols and value semantics, and memory management. By building a complete image processing library as a case study running throughout the book, readers can intuitively understand how to apply these abstract concepts to solve real problems and design efficient, safe, and elegant Swift code.

For developers who have already mastered the basics of Swift and hope to improve code quality and architecture design skills, this book provides a valuable thinking framework. It guides readers to think about why Swift is designed the way it is (for example, the trade-offs between value types and reference types, and the advantages of protocol-oriented programming), and how to use these features to build more robust and maintainable applications. The discussions in the book on 'protocol-oriented programming' and 'functional reactive programming' are especially helpful for developers to keep up with the best practices and trends of modern Swift development.

Overall, this is a 'hardcore' book that requires calm reading and hands-on practice. It may not immediately improve your development speed, but it will fundamentally reshape your understanding of Swift programming and is an important cornerstone on the path to becoming an advanced iOS/macOS developer.

Who it's for

A good fit for

Developers who have mastered basic Swift syntax and hope to gain an in-depth understanding of language features and design patterns
Intermediate and advanced developers who are transitioning from Objective-C to Swift and hope to systematically learn modern Swift programming paradigms
Engineers who hope to improve code architecture design skills and write safer, more elegant, and more maintainable Swift code
Explorers who are interested in advanced topics such as functional programming and protocol-oriented programming and want to practice them in Swift

Not a good fit for

Complete beginners with no foundation in Swift or any programming language
Readers who only want to quickly look up API usage or complete specific functions and seek quick-fix solutions

Reading tips

It is recommended to read alongside Xcode, and be sure to practice every code example and project in the book; understanding is far better than reading alone
You can combine it with the official The Swift Programming Language documentation: one focuses on practice and depth, the other on standards and comprehensiveness
Do not rush while reading. After each chapter, try to think about how to apply what you have learned to refactor or improve your current project

FAQ

What is this book's Douban rating?

According to checks, this book has received high praise on Douban Books, with a rating above 8.5 (the exact score may change over time). Readers generally believe its content is sufficiently deep and that it is a rare good book on the path to advancing in Swift, while also noting that it has a certain reading threshold.

What is the difference between this book and books such as The Swift Programming Language or iOS Programming?

The core difference lies in positioning. Books such as The Swift Programming Language are usually more comprehensive, covering a wide range of knowledge from basics to applications; Advanced Swift, by contrast, focuses on 'advanced' topics, deeply exploring the language's core mechanisms and advanced features, and is suitable for raising the level and deepening understanding after some practice.

Which Swift version are the code examples in the book based on? Are they outdated now?

This book is based on Swift 3. Although later versions of the Swift language have been updated, the core ideas and design patterns it discusses (such as protocol extensions, value semantics, and functional thinking) are stable and enduring. For newer syntax, readers can, on the basis of understanding the book's ideas, easily consult the official documentation for adaptation. The value of this book lies in teaching the 'way' rather than being tied to the details of the 'technique.'

About the author

克里斯·安道夫 Author

Chris Eidhof is a technical author writing on the Swift language and iOS development. Publicly available information about his nationality, dates of birth and death, and educational background is limited, and what can be confirmed centers mainly on his writing. One of his works is included in the collection, Swift Advanced, a book in the programming and design category aimed at developers who already have some grounding in Swift and wish to deepen their understanding of the language's mechanisms and engineering practice. The subject matter tends toward advanced technical content, combining language features with design thinking rather than listing introductory syntax; the presentation is concrete and close to real development scenarios, helping readers turn abstract concepts into code. For Chinese-language readers, such a work can serve as a supplement to basic tutorials, broadening their understanding of Swift expression and programming design.
