Hi All! Has anyone see this error:
Coroutines must be initialized from the main thread: call 'initMainThread' from the main thread first ?
I am launching raw socket API on iOS, ktor version 2.0.0-beta-1

@Vsevolod Tolstopyatov [JB] could you help?

Yes I've seen it before. It happens if you call coroutines code for the first time on a background thread.

[Thomas]

You could call coroutines code from a main thread first, which should solve the issue

[Leonid Golberg]

So, workaround - call any coroutine on main thread?

[Leonid Golberg]

Cool, thanks, I'll try!

[Thomas]

Yes and after that you can use it from background threads

[Thomas]

Don't forget to call initRuntimeIfNeeded() in your background thread too

[Leonid Golberg]

Thanks, @Thomas this helped!
