Hello, In my app, I have a timer. When the app is in the foreground, everything is good. Timer runs. When the app goes to background, the timer stops. This is surely the iOS shuts down the app. I read multiple documents and pages about the background tasks and background task strategies. However, none of them are able to describe a scenario which is similar to Apple’s Stopwatch or Alarm or Timer. How can I achieve a similar functionality? Thanks.

Hi, For a user who subscribed a product via In-App Purchase, how does the application backend know that the user is still subscribed? The initial purchase happens on the mobile app. Via receiving and validating the receipt of initial purchase, the backend of mobile app would be informed. However, what is the appropriate option for the subsequent subscription payments? How do I know whether the user is still paying? Thanks.
