A Boolean value that indicates whether observer queries receive updates while running in the background.

## Discussion

If this key is <doc://com.apple.documentation/documentation/Swift/true>, your app can enable background delivery of <doc://com.apple.documentation/documentation/HealthKit/HKObserverQuery> instances by calling the HealthKit store’s <doc://com.apple.documentation/documentation/HealthKit/HKHealthStore/enableBackgroundDelivery(for:frequency:withCompletion:)> method. By default, the value is <doc://com.apple.documentation/documentation/Swift/false>.
