[Book Update] Async Chapter is Done! Looking for Feedback.

The Async Chapter is one of the new additions to the 2nd edition of The iOS Interview Guide. It covers all things async: GCD, Swift Concurrency, RxSwift, Combine, Threads, etc.

I’m finally done with the Async chapter of The iOS Interview Guide! It took a while, been busy with work, took a detour, but now I’m back to working on the second edition reinvigorated.

This chapter is the new addition to the book, not a refactoring of an existing chapter. That’s also partially why it took me a while to finish it. It covers all things async: Threads, Swift Concurrency, MainActor, Actors, AsyncStream, GCD, NSOperation, RxSwift, Combine, etc.

The goal is to give the reader a broad overview of options to execute asynchronous work on iOS so that they know what to pick best for the job and problem at hand.

Any type of feedback is welcome, from tiny typos to critique of the whole chapter structure.

Let me know if you want to get the draft by emailing me, commenting, or DMing on Substack.
