# predicateForObjects(from:) Returns a predicate that matches all the objects that were created by any of the provided sources. ``` class func predicateForObjects(from sources: Set) -> NSPredicate ``` ## Parameters `sources` A set of sources that have saved data to the HealthKit store. ## Return Value A predicate that matches all the objects created by any of the provided sources. ## Discussion Use this convenience method to create a predicate that finds all the objects from a specified set of apps or devices. The following sample uses both the convenience method and a predicate format string to create equivalent predicates. ```swift let fromSources = HKQuery.predicateForObjectsFromSources(sources) let explicitFromSources = NSPredicate(format: "%K IN %@", HKPredicateKeyPathSource, sources) ``` ## See Also [`source`](/documentation/HealthKit/HKObject/source) A HealthKit source, representing the app or device that created this object. [`HKSourceQuery`](/documentation/HealthKit/HKSourceQuery) A query that returns a list of sources, such as apps and devices, that have saved matching queries to the HealthKit store. --- Copyright © 2026 Apple Inc.
