AVAggregateAssetDownloadTask resume

Hi all,

I have seen this discussed a number of times, but I'm afraid I haven't found a solution which works for me.

Gven an AVAggregateAssetDownloadTask, when the user force quits the application, is there a way on launch to resume from where the app left off?

I have tried a number of things:

1. I have tried to point the application to the locally stored HLS download (seems illogical, but the internet suggested it.

2. I have implemented

    _ session: URLSession,
    task: URLSessionTask,
    didCompleteWithError error: Error?
  )

I can see the cancelled task, but there is no resume data associated with it.

Any help would be appreciated.
