Apple's Workout app has pause / resume buttons. I don't see any API calls on HKHealthStore that corresponds to these functions thus I guess they simply stop collecting samples coming from streaming HKQuery while it's paused.
What I'm interested in is: how to later on fetch that same workout from HealthKit and how to recognize when the pause/continue happened? If I record a workout with the watch, I want to later on be able to pick it up on my iOS app and then display a chart of pace vs HR vs distance and mark each pause when it happened.
I want to avoid having to maintain a separate log of workouts and timestamps just for this, since I can get everything else I need from HealthKit.
