Are there any articles out there that compare coroutines to Apple’s Grand Central Dispatch (GCD)? Curious to read up on comparisons between the two.

I haven't seen any. They're both lambda-based abstractions for managing async work (background and main thread). The main difference for an app dev is that coroutines + suspend funs give you structured concurrency, which you don't get with GCD. For example, ensuring async work is complete in your tests in the GCD world is a chore. In coroutines, it's all done (for the most part assuming all parties aren't doing things low GlobalScope.launch) when runBlocking completes in your test

That's the short version I think

Awesome thanks @basher!
