Hi,

I'm trying to implements an interface that returns Flows on swift, something like callbackFlow {} in Kotlin. For example:

// Kotlin common
interface Repository {
    fun location(): Flow<LatLng>
}

// Kotlin android
class AndroidRepository : Repository {
    override fun location(): Flow<LatLng> = 
        callbackFlow {
            // some implementation 
        }
}

How should I implements those on swift?

// Swift iOS
class IosRepository : Repository {
    func location() -> // how to?
}

I'm already looking at the topics but unable to find anything that solves above issue. Am I missing something here?

Implementing (returning) Flow in Swift is hard. Instead implement your logic in Kotlin using platform.Foundation and use https://github.com/rickclephas/KMP-NativeCoroutines

Yup, I figure it is hard to right now to do what I want. Got some clearance on how some lib handle this kind of issue from this firebase-kotlin library: https://github.com/GitLiveApp/firebase-kotlin-sdk
