The low heart rate samples are read-only. You can request permission to read the samples using this identifier, but you can’t request authorization to share them. This means you can’t save new low heart rate events to the HealthKit store. To add test data in iOS Simulator, open the Health app and select Browse > Heart > Low Heart Rate Notifications > Add Data.
