I am working on an iOS app. I have two question regarding:
1. I need to fetch health data while my phone is locked. Is there any way to fetch health data either from iPhone device or apple watch?
2. I also stuck to fetch heart rate.
fetch data from healthkit if iphone device is locked.
1. Your app may not be able to read HealthKit data for the following security reasons:
"For security, the HealthKit store is encrypted when the device is locked, and the HealthKit store can only be accessed by an authorized app. As a result, you may not be able to read data from the store when your app is launched in the background..."

2. There are many options when fetching heart data and very many public code samples to do this. You need to show your code or ask a detailed question for us to help.
