Has anybody found a way to pass a `DispatchQueue` from Swift to a kotlin API?

Has anybody found a way to pass a DispatchQueue from Swift to a kotlin API?

[Rainer Schlonvoigt]

from what i can see Kotlin exposes dispatch queues as NSObject * but a dispatch_queue_t is actually supposed to be a NSObject<OS_dispatch_queue>*

[Rainer Schlonvoigt]

and without this extra protocol adherence, the Swift <-> ObjC interop breaks down

[Rainer Schlonvoigt]

so i don’t see any way to pass a Swift DispatchQueue

Hi there! Try this one:

// Swift code:
  let queue = DispatchQueue(label: "queue")
  KotlinClassKt.setQueue(queue: queue)

// KotlinClass.kt :
  fun setQueue(queue: dispatch_queue_t) {
    dispatch_async(queue) {
      println("Hello from queue")
    }
  }
