# predicateForWorkouts(with:duration:)

Returns a predicate for matching workouts based on their duration.

## Declaration

```swift
class func predicateForWorkouts(with 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 workouts based on their duration. This predicate works only on workouts.

## Discussion

Discussion Use this convenience method to create a predicate that matches against a workout’s duration. The following sample uses both the convenience method and a predicate format string to create equivalent predicates.
