Is it true that only pure Objective-C cocoapods can be included in a KMM project? I found this Starscream library for WebSockets, it seems very popular among iOS developers but it's written in Swift.

I know that doesn't really answer your question but you can also do WebSockets with

NSURLSessionWebSocketTask

on iOS 13+

@mbonnin I'm already using it, it's available right out of the box... but, I didn't manage to get a callback or notified in any other way when the connection drops or when I turn off Wi-Fi. That's a deal breaker and that's why I need another solution

Ouch, yea, that hurts

If the Swift pod exposes an interface for objC, it can be used from Kotlin. You also could write a wrapper in Swift that provides an ObjC interface.

the API that kotlin uses to bridge must be objective-C

does the documentation cover an example of bridging? or does someone have an article example?

the libcurl sample in the K/N samples repo

Starscream use

URLSessionWebSocketTask

under the hood anyway, you can take a look at how they use it internally.

@Antoine Lamy

Starscream works with iOS 8/10.10

How can it use

URLSessionWebSocketTask

that's only available with iOS 13+ ?

It probably uses multiple APIs

Then I'm wondering what you get by using the

URLSessionWebSocketTask

"backend", I guess smaller binary size

On iOS 12+ they use

NWConnection

and bellow that they use Foundation
