# springLoadingEntered(_:)

Returns whether to enable or disable spring-loading when a drag enters the bounds of the spring-loading destination.

```
@MainActor optional func springLoadingEntered(_ draggingInfo: any NSDraggingInfo) -> NSSpringLoadingOptions
```

## Parameters

`draggingInfo`

An object of type `NSDraggingInfo`, which provides information about the drag event, including the dragged data.

## Return Value

A value of type `NSSpringLoadingOptions` to enable or disable spring-loading. Returning a value of `NSSpringLoadingEnabled` enables typical spring-loading behavior that is appropriate in most cases.

## Discussion

This method is called when a drag enters the bounds of the spring-loading destination. It returns a value of type `NSSpringLoadingOptions` to enable or disable spring-loading for the destination.

This method provides an opportunity to perform work in preparation for spring-loading becoming engaged.

Note that you *must* implement either this method or [`springLoadingUpdated(_:)`](/documentation/AppKit/NSSpringLoadingDestination/springLoadingUpdated(_:)) to enable spring-loading.
