Hi all,

I wonder if anyone has hands-on experience with `Flow` in MPP/KN modules? Got any tips &amp; tricks?

I'm trying to expose shared repository layer for iOS/Android, and considering which `Observable` implementation to expose. Would really like to avoid `Reaktive` , having already coroutines and RxJava in the project...
Thanks in advance!

Flow can not be directly exposed to Swift as suspend functions are not available from there. You will need to wrap Flow into something based on regular callbacks with cancellation. Reaktive can be exposed. Also both Flow and Reaktive are based on extension functions. They are a bit hard to call from Swift. We are considering Swift extensions for Reaktive.

Take a look at this: <https://github.com/JetBrains/kotlinconf-app/blob/master/common/src/mobileMain/kotlin/org/jetbrains/kotlinconf/FlowUtils.kt>

They created `CFlow` which exposes a watch function that you can use on Swift.

On your `Flow`, you can use `wrap()` to transform it to a `CFlow` then to consume it you use `Flow.watch { ... }`

Thank you for the responses! That's really helpful!
