Hello everybody,
Iam developing KMM used by iOS and Android client. I need to use websockets there.Do you have experience with any library which works both for iOS and Android part?
Thanks

Ktor?

[Tom Wayne]

According to the KTOR doc:
Ktor provides Websocket client support for the following engines: CIO, OkHttp, Js.

None of them is compatible with iOS so it looks like I cant use it for WS on iOS.

[Big Chungus]

CIO is available on ios. Just checked here

@Big Chungus Wait, you use the CIO engine on iOS too?

[Big Chungus]

I don't do any IOS development, I'm just saying that CIO client engine library is available on IOS

Search by ktor cio

I tested it with CIO, but TLS sessions are not supported on Native platform. Fortunately, you can use ktor-client-ios, based on iOS URLSession

WebSockets aren't supported in ktor yet. But we have our own implementation. https://github.com/ln-12/kmm-websocket This might be helpful @Martin Rajniak

@Jolas is it compatible with iOS < 13?

also you can use custom ktorEngine wrapper as i do here - https://github.com/Alex009/ktor-client-ios-websockets
later this engine will be available in moko-network - https://github.com/icerockdev/moko-network/issues/149
