I have used below source code to get the steps from HealthKit. It's working fine many users but few users face the issue regards to get the steps from HealthKit in the our Application. After tracking the logs that issue found **: Error Domain=com.apple.healthkit Code=3 "Unable to invalidate interval: no data source available." **
Please help to know what exactly issue in the below source code.
