# predicateForWorkouts(with:totalSwimmingStrokeCount:) Returns a predicate that matches workout samples based on the number of strokes while swimming. ``` class func predicateForWorkouts(with operatorType: NSComparisonPredicate.Operator, totalSwimmingStrokeCount: HKQuantity) -> NSPredicate ``` ## Parameters `operatorType` The operator to use when comparing the sample to the target number of flights climbed. `totalSwimmingStrokeCount` A quantity representing the target stroke count. ## Return Value A predicate that matches workouts based on the number of strokes while swimming. ## Discussion This convenience method creates a predicate that compares the number of swimming strokes during a workout with a target number. The following sample uses the convenience method and a predicate format string to create equivalent predicates. ```swift // Creating a predicate using the convenience method. let swimmingStrokeCount = HKQuantity(unit: HKUnit.count(), doubleValue: 500.0) let longSwim = HKQuery.predicateForWorkouts(with: .greaterThanOrEqualTo, totalSwimmingStrokeCount: swimmingStrokeCount) // Creating a predicate using a predicate format string. let explicitLongSwim = NSPredicate(format: "%K >= %@", HKPredicateKeyPathWorkoutTotalSwimmingStrokeCount, swimmingStrokeCount) ``` ## See Also [`HKPredicateKeyPathWorkoutTotalSwimmingStrokeCount`](/documentation/HealthKit/HKPredicateKeyPathWorkoutTotalSwimmingStrokeCount) The key path for accessing the number of strokes during a swimming workout. --- Copyright © 2026 Apple Inc.
