Trigger download in background

[parim]

Recently, I was able to confirm the completed event in background.

It looks great!
However, when I was trying download in background by receiving push notification, it didn't start downloading unless I open the app.
Is it possible to start download in background?

The problem is not in the library but the iOS. When your App receives push notification it runs for a very short time in main thread. All subsequent enqueued operations (not in main thread) are scheduled for later executions when the app become active. That's why the download in background performs only when you activate it again.
