HealthKit data inaccessible in background

Question

I want to pull HealthStore data in the background using background fetch but I keep getting an error: Error Domain=com.apple.healthkit Code=6 \"Protected health data i

Answer 1

As stated in the documentation you quoted there's no way to access HealthKit data while the phone is locked. However, you can access the data if the phone is unlocked and your app is in the background. So if background fetch happens while the phone is unlocked you will be able to access the data.
