'Keeping iOS widget up to date with remote data
I am implementing an iOS widget and trying to determine the refresh schedule. I read Apple's documentation for Keeping a Widget Up to Date and saw this tip:
Important
Plan ahead if your widget makes requests to a server when it reloads, and uses afterDate() with a specific date in timeline entries. WidgetKit tries to respect the date you specify, which may cause a significant increase in server load when multiple devices reload your widget at around the same time.
It's a good tip but doesn't offer any suggestions for how to prevent this scenario. If I need to refresh the data from the remote server once a day at midnight (or any arbitrary time) what would be best practice here to avoid overloading the server?
