With coroutines yet to be released for iOS, what is the proper way in common code for
1) cross-thread access for some models (not simple stateless objects)
2) thread switching (ui->bg->ui)
I want to achieve something like

fun search(query: String, model: SearchModel, view: SearchView): Job {
        val cancellableJob = launch(CommonPool) {
            val data = model.search(query) // (1)
            withContext(UI) {
                view.showData(data) (2)
            }
        }
        return cancellableJob
    }

You can always try wrapping your favorite native iOS async APIs in expect/actual declarations

I've already done 2) with async_dispatch, but 1) is still needed

For global states the only known workaroud is using C interop:

And maybe konan.worker.AtomicReference

AtomicReference differs from JVM (at least fqdn), but doesn't work properly for non-objects (but I'm still researching)

[msink]

For simple numbers there are AtomicInt and AtomicLong

I need at least a list of objects

meh, forgot about initRuntimeIfNeeded() again 😞

I think it should be something like RCU in linux kernel
