I have some doubts about how HealthKit background delivery has been behaving, any information would be greatly appreciated.
- After setting up background delivery and setting the frequency to hourly, my application gets called only ocassionally in the background, around two times every 5 hours, Is this normal behavior?
- Do HKObserverqueries need to be recreated everytime the app launches from a terminated or similar state?
- Is there any delay between enabling the background delivery and actually getting the background delivery, assuming there is new data available every hour?
- The HKObserverQueries UpdateHandler are getting executed everytime the app is brought to the foreground, is this expected behavior?
Regarding the completionHandler that is received in the updateHandler of HKObserverQueries:
- Should the completionHanlder be called right away inside the UpdateHandler?
- If for some reason the three strikes are reached due to not calling the completionHandler in a timely manner. Does background delivery stop permanently?
I have a sample project ready if needed.
