Background uploads do not appear to work

Open spatialbits opened this issue 3 years ago • 0 comments

I am a Flutter developer integrating TUSKit into our app and having difficulties getting background uploading to work.

So I am attempting to run the example app just to observe the background capability, but it looks like it only runs while the app is in the foreground.

Running the TUSKit Demo app using latest master. The log output below is the result of the following sequence:

  1. Select an image from the picker.
  2. Allow upload to begin.
  3. Immediately switch to another app.
  4. Upload halts (or seems to, log output stops anyways).
  5. Switch back to demo app.
  6. A timeout error is logged
  7. A couldNotUploadFile error is logged.

I'm really new to iOS native and Swift and so this could be the result of me just misunderstanding of the library. If that is the case, I would very much appreciate some guidance on applying background uploads with TUSKit.

For reference, I have been following this guide that describes some common pitfalls with developing background uploads.
