# UICollectionViewDropCoordinator

An interface for coordinating your custom drop-related actions with the collection view.

```
@MainActor protocol UICollectionViewDropCoordinator : NSObjectProtocol
```

## Overview

You don’t create instances of this class yourself. When a drop occurs in the collection view, UIKit creates an instance of this class and passes it to your [`collectionView(_:performDropWith:)`](/documentation/UIKit/UICollectionViewDropDelegate/collectionView(_:performDropWith:)) method. Use the object to let the collection view know how you want to animate the dropped items into position.

## Topics

### Getting the Dragged Items

[`items`](/documentation/UIKit/UICollectionViewDropCoordinator/items)

The items being dragged.

### Getting the Drop Location

[`destinationIndexPath`](/documentation/UIKit/UICollectionViewDropCoordinator/destinationIndexPath)

The index path at which to insert the item in the collection view.

### Animating Items to Their Destination

[`-  dropItem:toItemAtIndexPath:`](/documentation/UIKit/UICollectionViewDropCoordinator/drop(_:toItemAt:))

Animates the item to the specified index path in the collection view.

[`-  dropItem:intoItemAtIndexPath:rect:`](/documentation/UIKit/UICollectionViewDropCoordinator/drop(_:intoItemAt:rect:))

Animates the item to the specified rectangle in the collection view.

[`-  dropItem:toTarget:`](/documentation/UIKit/UICollectionViewDropCoordinator/drop(_:to:)-7w5rn)

Animates the item to an arbitrary location in your view hierarchy.

[`-  dropItem:toPlaceholder:`](/documentation/UIKit/UICollectionViewDropCoordinator/drop(_:to:)-l5tg)

Animates the item to the specified location and inserts a placeholder cell at that location.

### Getting the Session Information

[`session`](/documentation/UIKit/UICollectionViewDropCoordinator/session)

The drop session containing information about the transaction.

[`proposal`](/documentation/UIKit/UICollectionViewDropCoordinator/proposal)

The current proposal for how to incorporate the dropped items.
