https://ktor.io/docs/websocket-client.html

It looks like the class that’s not found is NSURLSessionWebSocketMessage, and the documentation here says “The Ktor client supports WebSockets for the CIO, OkHttp, and Js engines.” Darwin (iOS) isn’t listed.

Something to note is that 2.0.0-beta-1 works for me.
