# referenceView

The view to place the halo effect above.

## Declaration

```swift
weak var referenceView: UIView? { get set }
```

## Discussion

Discussion If you set this property, the halo effect appears above this view. If you also set containerView, this reference view must be a descendant of the container view. The system ensures that the halo effect is in the container but visually above the reference view.
