Advanced Swift book updated for Swift 5.6

Along with the version of Swift, the best book about it, Advanced Swift by objc.io, has also been updated. In the new edition:

• Added a chapter about Swift Concurrency
• Improved content about property wrappers, function builders, protocols and generics.

The update is free for everyone who bought previous versions.

In this book, we’ll write about advanced concepts in Swift programming. If you have read the Swift Programming Guide, and want to explore more, this book is for you.

Swift is a great language for systems programming, but also lends itself for very high-level programming. We’ll explore both high-level topics (for example, programming with generics and protocols), as well as low-level topics (for example, wrapping a C library and string internals).
