Access real-time heart rate data

Hi everybody,


in "What's New in watchOS 4" - https://developer.apple.com/watchos/ - Apple wrote: "Fitness apps can also access real-time heart rate data..." Currently I'm using a workout session in my app with a HKAnchoredObjectQuery to read the heart rate data from the watch. With watchOS 4,beta 2 it works fine but I only get a new heart rate every 4 seconds respectively a HKQuantitySample. For my requirement I need a real-time notification for every heartbeat but I can't find a suitable api for my requirement. Now my question: Is it possible to get real-time heart rate respectively the heartbeat in watchOS 4?


Thanks for your help

Hi - did you ever find an answer for this? I also need real-time heart rate data, and can only seem to get the udpates once when the workout is finished.


Thanks!
