Use Task Services to get a short background execution window when your app is being suspended (ex: user presses Home). This is best for quick critical work (save state, finish a small upload, cleanup).

Actions (4)

• TaskServicesStartTaskAndAllowInBackground: Start background allowance and get a taskId (also exposes an optional quota-expiry event).

• TaskServicesCancelTask: End the allowance when your work is done.

• TaskServicesGetError: Read cached error details after a start failure event.

• TaskServicesCancelTaskGetError: Read cached error details after a cancel failure event.

Key pattern

1. Start: TaskServicesStartTaskAndAllowInBackground → store taskId.

2. Do work in the next state(s).

3. End: TaskServicesCancelTask (pass taskId, or leave empty to use TaskServicesUtils.LastTaskId).

Notes

• iOS background time is limited (often around ~30 seconds). Keep work short and always handle quota expiry.

• Use quotaWillExpireEvent (on TaskServicesStartTaskAndAllowInBackground) as a Global Transition if you need an emergency “save minimal” path.
