I have an app that needs to refresh a server whenever a Contacts record is updated. I can observe Contacts, but that only seems to work when my app is running (and in foreground, which it cannot be on iPhone if the Contacts app is being updated). I want it to process, even if my app is in background, or has been terminated (swiped away), or after a phone restart.
The only way I can think of is to periodically push a notification to the app from an external server. Is there any way to run a timer that sends a notification to the app on a periodic basis? The timers you can set seem to run even if the Clock app is swiped away, or following a phone restart. Is there anything like that I could use to wake my app periodically?

No. There’s a bunch of background (ahem!) to this in iOS Background Execution Limits.
Share and Enjoy
