My question is plain and simple. Can i run custom code in the updateHandler when I´ve executed a HKWorkoutSession and is listening for HeartRate samples? (Even when the Watch is locked from "wrist down" movement) If this i possible what are my limitations?
I´m interested in processing the HeartRate data when my code receives them. I don´t have a device yet so I haven't been able to test it yet.
Would love your thoughts on this if anyone have experimented with an actual device.
