# springLoadingHighlightChanged(_:)

Updates the destination’s user interface to display a new highlighting style during a spring-loading operation.

```
@MainActor func springLoadingHighlightChanged(_ draggingInfo: any NSDraggingInfo)
```

## Parameters

`draggingInfo`

An object of type `NSDraggingInfo`, which provides information about the drag event, including a highlighting style to apply.

## Discussion

During a spring-loaded operation, a destination may initiate animated highlighting to visually cue the user that spring-loading has been engaged or disengaged. This method is called as different stages of this animation are reached, providing an opportunity to change the highlighting style. Check the `springLoadingHighlight` property of the `draggingInfo` object to determine the style of highlighting to apply. Then, update the destination’s user interface accordingly.

> Important:
> Do not use highlighting as a means to determine whether spring-loading has actually been activated or deactivated. The ``doc://com.apple.appkit/documentation/AppKit/NSSpringLoadingDestination/springLoadingActivated(_:draggingInfo:)`` method alerts your app when spring-loading activation occurs.
