DispatchQueue.main does not work

[OlofT]

It seems something is blocking the main thread, calling this from Android, into Swift:

        print("In main? \(Thread.isMainThread)")  //true
        DispatchQueue.main.async {

            //never called
            print("MAIN async")
        }

I imagine this is due to Android owning the main thread and running its loop there all the time, so the question is perhaps - how to get it to yield for Swift at regular intervals? Or how to make Swift's main process itself on another thread?

The solution is to start the Swift process in another thread:

import kotlin.concurrent.thread
...
thread {
    System.loadLibrary("WeatherCoreBridge")
    JavaSwift.init()
    ....
}
