Hello!, I have a question
How to use Dispatcher.IO?
Kotlin Multiplatform doesn’t support Dispatchers.IO ?
kotlinx-coroutines = "1.8.1", kotlin = "2.0.0"
_commonMain_._dependencies_ *{*
implementation(_libs_._kotlinx_._coroutines_._core_)
}
_desktopMain_._dependencies_ *{*
implementation(_libs_._kotlinx_._coroutines_._swing_)
}

It worked for android & iOS projects,
But I can't import in Android & iOS & Desktop & WasmJS projects [I tried upgrading to version 1.9.0-RC, and there was no change.]

IO only exists on the JVM (and Android).

On JS, there are no threads, and no blocking IO, so it doesn't make sense.

I don't know about iOS.

Mistake?

@CLOVIS That's why, thank you! (Yes, that was a mistake.)

You can do something like
expect val defaultAsyncDispatcher : CoroutineDispatcher

in jvmMain:
actual val defaultAsyncDispatcher : CoroutineDispatcher = <http://Dispatchers.IO|Dispatchers.IO>

everywhere else:
actual val defaultAsyncDispatcher : CoroutineDispatcher = Dispatchers.Default (or Dispatchers.Main)

You can use this extension property in common code

Sorry I didn't notice you use wasm
Dispatchers.IO is available only on JVM and native targets. There is no concurrency on js and wasm
