It’s actually not a combineLatest semantics.

For the combineLatest I’d recommend using select operator, for merging two channels kotlinx.coroutines has zip operator: https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.experimental.channels/zip.html

Why is it not a combineLatest semantic?

[Vsevolod Tolstopyatov [JB]]

ch1: “John”
ch2: 30
ch2: 32

combine latest over these two channels will produce Person("John", 30), Person("John", 32), it’s not a desired behavior for a person example, is it?

[Paul Woitaschek]

Exactly that is desired

When the user changes it's age, that's the new state I want to render 🙂

[Vsevolod Tolstopyatov [JB]]

oh, sorry then 🙂

@Paul Woitaschek Here's my solution, which works for any number of channels or callbacks, of any type: https://gist.github.com/LouisCAD/d9d1adbd3b4fd36d9dc121658fefd16f
Let me know if you need help figuring out how to use it.

[Paul Woitaschek]

Thanks, after figuring out forever I implemented it in rx and it's way simpler

[Paul Woitaschek]

My conclusion so far is that with anything stream based, rx makes it simpler where with whenever I have a rx.Single / Maybe coroutines work better
