background▌

Trust system reminders as agent progress notifications. Don't poll.

Background execution is a privilege, not a right. iOS actively limits background work to protect battery life and user experience. Core principle: Treat background tasks as discretionary jobs — you request a time window, the system decides when (or if) to run your code.

Build robust background job processing systems with distributed task queues, worker pools, job scheduling, error handling, retry policies, and monitoring for efficient asynchronous task execution.

Register, schedule, and execute background work on iOS using the BackgroundTasks framework, background URLSession, and background push notifications.
