What is the best/official way to write a custom MainCoroutineDispatcher? I wrote one for SWT but requires use of internal and experimental API

If you're on the JVM, you could just create a new Executor with the Executors API (https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/Executors.html), and then convert it to a dispatcher with the asCoroutineDispatcher extension.

If you need it to be the main-dispatcher, I guess you need to somehow register it to a ServiceLoader, like the other main-dispatchers (https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/-dispatchers/-main.html)

This doesn't give me a MainCoroutineDispatcher

I made it work but I wonder if there is a better way without internal/experimental api. the way via ServiceLoader smells

[Vsevolod Tolstopyatov [JB]]

There are no official ways to write a custom dispatcher that will be available via Dispatchers.Main

[gattacus]

there should be. It is quite handy if you write code for different platforms. Android and desktop (SWT) in my case

[Vsevolod Tolstopyatov [JB]]

Could you please file an issue on github with your use-case?
