I've been trying to update the UI while in the always on state and can't seem to get it to work. My app is a workout app so from the documentation it seems like I should still be able to update the UI just at a lower frequency.
From the documentation: "Apps running a background session, such as a workout session or background audio session, remain onscreen as long as the session is active. Unlike frontmost apps, apps running a background session can continue to update their user interface; however, to save battery life, the system reduces the update frequency."
All of the documentation for designing for Always On seems to just be in SwiftUI and I was able to get a demo working without issue using the TimelineView and PeriodicTimelineSchedule seen here https://developer.apple.com/documentation/watchkit/designing_your_app_for_the_always_on_state. Is there anything I can do to get this to work with a WKInterfaceController or is SwiftUI the only option?
