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

## Declaration

```swift
nonisolated func draggable<V, T>(_ payload: @autoclosure @escaping () -> T, @ContentBuilder preview: () -> V) -> some View where V : View, T : Transferable

```

## Parameters

- `payload`: A closure that returns a single class instance or a value conforming to Transferable that represents the draggable data from this view.
- `preview`: A doc://com.apple.SwiftUI/documentation/SwiftUI/View to use as the source for the dragging preview, once the drag operation has begun. The preview is centered over the source view.

## Discussion

Discussion Applying the draggable(_:preview:) modifier adds the appropriate gestures for drag and drop to this view. When a drag operation begins, a rendering of preview is generated and used as the preview image. var title: String var body: some View {     Color.pink         .frame(width: 400, height: 400)         .draggable(title) {              Text("Drop me")          } } To customize the lift preview, shown while the system transitions to show your custom 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.
