# SRFetchResult Recorded data that a sensor reader fetches. ``` class SRFetchResult where SampleType : AnyObject ``` ## Overview A sensor reader’s [`delegate`](/documentation/SensorKit/SRSensorReader/delegate) receives instances of this class from the [`sensorReader(_:didCompleteFetch:)`](/documentation/SensorKit/SRSensorReaderDelegate/sensorReader(_:didCompleteFetch:)) when a fetch request finishes successfully. Results are in the form of samples, which are of varying types depending on the reader’s sensor. For a list of sample types per sensor, see [`Sample types`](/documentation/SensorKit/SRFetchResult/sample#Sample-types). ## Topics ### Sampling Data [`var sample: SampleType`](/documentation/SensorKit/SRFetchResult/sample) A recording that the sensor reader fetches. [`var timestamp: SRAbsoluteTime`](/documentation/SensorKit/SRFetchResult/timestamp) The time when the framework records the sample. ### Instance Properties [`var sourceDevice: SRSourceDevice?`](/documentation/SensorKit/SRFetchResult/sourceDevice) ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) [`NSCopying`](/documentation/Foundation/NSCopying) [`Hashable`](/documentation/Swift/Hashable) [`CustomDebugStringConvertible`](/documentation/Swift/CustomDebugStringConvertible) [`NSObjectProtocol`](/documentation/ObjectiveC/NSObjectProtocol) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`CVarArg`](/documentation/Swift/CVarArg) ### Inherits From [`NSObject-swift.class`](/documentation/ObjectiveC/NSObject-swift.class) --- Copyright © 2026 Apple Inc.
