# predicateForWorkouts(with:)

Returns a predicate for matching workouts based on the type of activity.

```
class func predicateForWorkouts(with workoutActivityType: HKWorkoutActivityType) -> NSPredicate
```

## Parameters

`workoutActivityType`

The type of activity. For a list of valid workout activities, see [`HKWorkoutActivityType`](/documentation/HealthKit/HKWorkoutActivityType).

## Return Value

A predicate for matching workouts based on the type of activity.

## Discussion

Use this convenience method to create a predicate that matches workouts based on their activity. The following sample uses both the convenience method and a predicate format string to create equivalent predicates.

```objc
NSPredicate *workout =
    [HKQuery predicateForWorkoutsWithWorkoutActivityType:
     HKWorkoutActivityTypeCurling];
 
NSPredicate *explicitWorkout =
[NSPredicate predicateWithFormat:@"%K == %d",
 HKPredicateKeyPathWorkoutType,
 HKWorkoutActivityTypeCurling];
```
