# predicateForWorkoutActivities(operatorType:duration:)

Returns a predicate for matching workout activities based on their duration.

## Declaration

```swift
class func predicateForWorkoutActivities(operatorType: NSComparisonPredicate.Operator, duration: TimeInterval) -> NSPredicate
```

## Parameters

- `operatorType`: The operator type to use when comparing the duration.
- `duration`: The target duration.

## Return Value

Return Value A predicate for matching workout activities based on their duration. This predicate works only on workout activities.

## Discussion

Discussion Use this convenience method to create a predicate that matches against an activity’s duration. To use this predicate, call predicateForWorkouts(activityPredicate:) to wrap this predicate inside a workout predicate. You can then use the workout predicate in your query. The following sample creates a predicate for matching workout activities with a duration of 30 minutes or longer. let longWorkoutActivityPredicate = HKQuery.predicateForWorkoutActivities(operatorType: .greaterThanOrEqualTo, duration: 60.0 * 30.0)

// Wrap the activity predicate inside a workout predicate. let workoutPredicate = HKQuery.predicateForWorkouts(activityPredicate: longWorkoutActivityPredicate)
