Sessions and data in iOS background transfers

Protecting data across devices, extensions, notifications and account changes.

Transfers may continue while the app is not visible. Logout and access changes must be reflected in ongoing work.

Evaluation approach

Bind tasks to accounts and transactions. Confirm correct destination ownership and prevent canceled jobs from restarting.

Application example

A download finishing after an account switch must not enter the new user's document list.

Limits and considerations

Closing a screen does not prove network work stopped. Preserve server authorization for each request.

Does completion imply correctness?

Check type, size, expected operation and account binding at completion. A downloaded file may need deletion or fresh authorization if the user logged out.

Checks and decisions

  • Record task ownership
  • Test logout cancellation
  • Validate completed files
