"Unlike other BGTask subclasses, BGContinuedProcessingTask starts in the foreground. In addition, your app needs to run the task only in response to someone’s action, such as tapping a button. If a person backgrounds the app before the task completes, a continuous background task can still perform operations"

Example use case: our app allows users to upload photos. Right now those uploads fail if the user immediately backgrounds the app -- the 5 sec termination window is not long enough for the upload to finish. If there was a way to hook into BGContinuedProcessingTask, then we could kick off the upload as a task from the foreground and ensure it keeps running even after the app is backgrounded.

If there's another way to achieve, would appreciate pointers. doesn't seem to quite do it because "the task may not run immediately after it is scheduled."
