# onDrag(_:)

Activates this view as the source of a drag and drop operation.

## Declaration

```swift
nonisolated func onDrag(_ data: @escaping () -> NSItemProvider) -> some View

```

## Parameters

- `data`: A closure that returns a single doc://com.apple.documentation/documentation/Foundation/NSItemProvider that represents the draggable data from this view.

## Return Value

Return Value A view that activates this view as the source of a drag and drop operation, beginning with user gesture input.

## Discussion

Discussion Applying the onDrag(_:) modifier adds the appropriate gestures for drag and drop to this view. When a drag operation begins, a rendering of this view is generated and used as the preview image. To customize the default preview, apply a contentShape(_:_:eoFill:) with a dragPreview kind. For example, you can change the preview’s corner radius or use a nested view as the preview. If you want to show a different preview, you can use onDrag(_:preview:). To use Transferable types directly and access a richer feature set — including multi-item drag via dragContainer(for:in:_:) — use draggable(_:) instead.
