## Discussion

Discussion Set this key on  a workout, workout segment, or a quantity sample that represents distance. Set its value to an HKQuantity object with a length unit. HealthKit assigns this metadata key to the segments it automatically creates for HKWorkoutActivityType.downhillSkiing and HKWorkoutActivityType.snowboarding workout sessions (Apple Watch Series 3 only).
