Third party iOS apps do in fact have access to background tasks. There’s even a variant dedicated to longer-running tasks, like lengthy file syncs. The difference is that instead of having an ever-running daemon, the developer schedules tasks with the system, and system decides when to run them based on network availability, battery charge, etc as well as the app’s behavior (badly written/inefficient background tasks and frequent high intensity task requests are penalized).
