Is a new edition coming to discuss concurrency?

I recently finished this edition of the book, but with Swift 5.5 there are concurrency features added to the language. I’m very interested to learn about that. However, the Swift Language Guide does a very poor job explaining it and I couldn’t make sense of the concurrency stuff at all.

I hope this book gets updated soon to cover the concurrency language features. You guys are sure to do a better job explaining that stuff!

Have a look at Grand Central Dispatch (GCD), a useful starting point.
