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.

This doesn't give me a MainCoroutineDispatcher

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

Dispatchers.Main

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

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