Should we use absolute or calendar Date when scheduling background tasks? I would guess it doesn't matter how we construct Date but I wanted to double check since WWDC videos show both ways. I've experienced some instances where background tasks ran much later than expected, and while this is not surprising since iOS has many factors to consider when they allot background execution time, the times of execution seemed to line up with the hours change between Absolute and Calendar time. Or And I understand there is no guarantee that the system will run the background task exactly or even near the date requested. Thanks!

When a user has multiple Apple Watches, can the secondary watches send messages to the iPhone via WCSession? WC Session Documentation - https://developer.apple.com/documentation/watchconnectivity/wcsession is quite limited on how to best support multiple Apple Watches. According to the docs: The Watch app on each watch stays in the active state This leads to me believe that each watch could still send a message to the iPhone via WCSession since the session remains active on each watch, but this is not clear. Can anyone confirm that multiple watches can send messages to one iPhone? Or point to other documentation that may be useful? (WCSession messages would be initiated through a background task or push notification).
