# reactionEffectGesturesEnabled

A Boolean value that indicates whether gesture detection triggers reaction effects on the video stream.

## Declaration

```swift
class var reactionEffectGesturesEnabled: Bool { get }
```

## Discussion

Discussion This property reflects the enabled state of Gestures in Control Center. Gesture detection runs only when the device’s active format supports reaction effects, which you determine by querying the value of the format’s reactionEffectsSupported property. This property is key-value observable. note: Your app can call performEffect(for:)independently the value of this property. The system intermixes reaction effects from either source.
