If you draw a parallel to Combine code — how would you build custom “operators” for your async sequence? …

I’ve been trying out various ways to extend and build upon the currently available Concurrency APIs introduced in Swift 5.5 I believe the Concurrency APIs are intentionally somewhat minimal so that developers would intentionally fall back on Combine for complex tasks. Maybe I’m right or wrong but I can see how a lot of people will want to extend the Concurrency APIs to suit better their current tasks. In this post I’ll code a couple of extensions that show how to easily build your own concurrent power-ups. …
