Hi! Sorry for the very late response.

I don' get why you need concurrent dispatches. Isn't it enough some like this (very simplified example code):

State & Actions:

enum DownloadState {
  case notStarted
  case progress(Double)
  case done
}

// mediaID is a string or something
let media: [MediaID: DownloadState]


struct DownloadMedia: AsyncAction, ActionWithSideEffect {
  let id: MediaID

  // update states to handle start, progress and completion

  sideEffect() {

     let progressClosure = { progress in
       dispatch(self.progressAction({ $0.progress = progress })
     }


     let completionClosure = { localURL in
       dispatch(self.completionAction({ $0.progress = progress })
     }

     dependencies.apiManager.getMedia(self.id, progressClosure, completionClosure)
  }
}

Actions are always sequential, but it doesn't matter because the download is actually parallel if yiu dispatch many DownloadMedia.

For the UI you can attach a listener to the store in the vc that handles the collection/table of bubbles instead of using a listener for each bubble.
Take a look at Tempura, if you haven't seen it https://github.com/BendingSpoons/tempura-swift

I hope it is more clear now

@bolismauro , failed to receive notifications from your reply. Thanks a lot for the explanation. I would have a try of this framework. For Reswift, we need to manaage the serial queue manually to make sure all actions dispatched are in the same serial queue to make sure they are sequential
