A modern programming language that makes developers happier.

kotlinlang

I’ve currently ended up doing (much simplified)
```async(UI) {
delay(10)
viewState.onNext(...)
}```
I guess an alternative to delay would be ```bg { Thread.sleep(10) }``` ?

You should use `launch(UI)` in your case instead of `async(UI)`. `async` creates a `Deferred` on which you're meant to call `await()` at some point. And it is not the same, because the `Thread.sleep(...)` blocks the thread (rendering it useless for the passed time), while `delay` is more like `handler.postDelayed(...)`
