workout information send to phone live

Question

I have created a heart rate monitor on the apple watch and that sends alerts to notifies you if your heart rate gets to low. After creating the app, I realized it does not run in the background. Is there a way to either force the app to run in the background on the watch or send the heart rate information to the phone?

Answer 1

I've investigated this, but don't have any practical experience (yet). From what I understand, watch apps in watchOS3 can capture continuous heart rate updates with these conditions:

• It's a full app (not just an extension).
• The app starts a workout
• Info.plist has the WKBackgroundModes key set

You'll need to either start the workout from the watch app, or if triggered from the companion iOS app you'll need to call start​Watch​App​With​Workout​Configuration:​completion:​ to start a workout session on the paired watch.
