To restart an iOS app programmatically, you need to use iOS Background Tasks to simulate an app restart. First, close the app using exit(0), which is generally discouraged except for testing. Then, utilize local notifications or background fetch to schedule the app’s reopening. Consider carefully, as Apple guidelines recommend against force-closing apps.
