SwiftyDropbox calling upload N times

Question

If I call upload N times, the calls return immediately, but will SwiftyDropbox create N simultaneous uploads or queue the uploads and upload one after another?

SwiftyDropbox uses Alamofire, and Alamofire should behave like NSURLSession, meaning it will not queue up the requests for you.

So if you make 10 requests in a row, the will likely timeout if they are long requests. 
You can solve this by dispatching your requests to a queue, and maxing out the number of concurrent operations to something like 2 or 3, or whatever makes sense for your app.
