# dragInteraction(_:sessionAllowsMoveOperation:)

Asks the delegate whether the session allows the move operation.

```
optional func dragInteraction(_ interaction: UIDragInteraction, sessionAllowsMoveOperation session: any UIDragSession) -> Bool
```

## Parameters

`interaction`

The interaction that called this method.

`session`

The drag session that should, or should not, allow the move operation.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the session allows moving drag items to the destination view; otherwise <doc://com.apple.documentation/documentation/Swift/false>. The default is <doc://com.apple.documentation/documentation/Swift/true> if you don’t provide this method.

## Discussion

The [`UIDropOperation.move`](/documentation/UIKit/UIDropOperation/move) operation only applies to drop activities within the same app. Drag items dropped onto another app are always copied.
