There have been a plenty of additions to the language lately: borrow, consume, Copyable, BitwiseCopyable, Escapable, various concurrency additions and so on. Are there any plans to address these? Some of these features have been around for 2-3 years, and I have yet to find a resource on the site that properly addresses these. While these may be not necessary for “casual coding” and it is perfectly possible to write code that works without (well, it’s what has been done since swift exists…) - but for performance tuning, or low level programming, these are a must. What would be a better place for them if not “Expert Swift”? If there is no intentions to address these - please change the book title at least.

Can’t speak for the author or Kodeco, but there have been a lot of books getting updated recently. I wouldn’t be surprised if this was as well.

Agree. I think concurrency in particular would be interesting update, would be great if they are able to update the concurrency book as well.

Hello @exchessplayerh,  
You’re absolutely right—these advanced features like `~Copyable`, `~Escapable`, and concurrency primitives are essential for performance-critical and low-level Swift. If “Expert Swift” doesn’t plan to cover them, it’s fair to question the title. A dedicated resource or updated edition would better serve developers pushing Swift’s boundaries.

Best Regards,  
Amy Henry

@aabrahamyan an option would be to reach out to the author and request this, feedback is important and may help push towards an update.

@amy598henry first time post! welcome to Forums.

I think that’s a fair concern—those features have been around long enough that they deserve proper, centralized documentation. If _Expert Swift_ isn’t the place for deeper performance and low-level topics, it would really help to know where that content is supposed to live.
