That's a great example, thanks! I did some looking, and I found a few[1] examples[2] of coroutines in Objective-C, though none of them seemed fully fleshed-out

That's a great example, thanks! I did some looking, and I found a few[1] examples[2] of coroutines in Objective-C, though none of them seemed fully fleshed-out.
