Apple does not technically provide developers with access to heart rate sensors in watchOS 2.0. What they do is direct access to heart rate data recorded by the sensor in HealthKit. See the answer to this question for more details.

Many of the iOS software suites are now available for watchOS, such as HealthKit.

You can use the HealthKit (HK) features and classes to calculate calories burned, heart rate, etc.

You can use HKWorkout to calculate everything about your workouts and access related variables, such as heart rate, just like you did with iOS before.

Read the Apple developer documentation to learn about HealthKit. They can be found at developer.apple.com .
