How does background processing work on iOS and how do you schedule work reliably?
Answer
iOS limits background execution to protect battery.
Use:
- BackgroundTasks framework (BGAppRefreshTask/BGProcessingTask)
- Background URLSession for uploads/downloads
Design work to be resumable, idempotent, and respectful of constraints (network/power). Expect scheduling to be opportunistic, not guaranteed.
