Any examples on how to use channels on iOS? I have a library that expects me to give a ReceiveChannel object, but in iOS I cannot instantiate Kotlinx_coroutines_core_nativeReceiveChannel because it has no accessible initializers

You need to invoke Channel() function and send elements to the resulting channel, which is a SendChannel as well as a ReceiveChannel.

Keep in mind that the type of channel may be relevant

looks like Channel also doesn’t have any initializers suitable for ios 😞

__attribute__((swift_name("Kotlinx_coroutines_core_nativeChannel")))
@protocol Eld_commonKotlinx_coroutines_core_nativeChannel <Eld_commonKotlinx_coroutines_core_nativeSendChannel, Eld_commonKotlinx_coroutines_core_nativeReceiveChannel>
@required
@end;

You can convert it to callback in Kotlin code. I think they don't meant to be touched from Swift

I'm not sure if this is the best approach, but here's my pet project. It uses Ktor & SQLDelight to fetch and cache GitHub API. It's quite messy, but it also uses Channel so may be you can grasp some idea.

I’ll have a look at it, thanks!
