# UIDropProposal

A configuration for the behavior of a drop interaction, required if a view accepts drop activities.

```
@MainActor class UIDropProposal
```

## Overview

If a view’s drop interaction delegate accepts dropped drag items, it must return a drop proposal in its implementation of the [`dropInteraction(_:sessionDidUpdate:)`](/documentation/UIKit/UIDropInteractionDelegate/dropInteraction(_:sessionDidUpdate:)) method.

## Topics

### Initializing a drop proposal

[`-  initWithDropOperation:`](/documentation/UIKit/UIDropProposal/init(operation:))

Initializes a new drop proposal with a drop operation type.

[`operation`](/documentation/UIKit/UIDropProposal/operation)

The drop operation that the drop interaction proposes to perform.

### Configuring a drop proposal

[`precise`](/documentation/UIKit/UIDropProposal/isPrecise)

A Boolean value that proposes that the drop interaction define the drop location precisely, such as at a specific point within existing text.

[`prefersFullSizePreview`](/documentation/UIKit/UIDropProposal/prefersFullSizePreview)

A Boolean value that indicates that the drag item preview should be shown at its full, original size.
