# NSDraggingInfo

A set of methods that supply information about a dragging session.

## Declaration

```swift
protocol NSDraggingInfo : NSObjectProtocol
```

## Overview

Overview You invoke the NSDraggingInfo protocol methods from within a class’s implementation of NSDraggingDestination methods. AppKit automatically passes an object that conforms to the NSDraggingInfo protocol as the argument to each of the methods that NSDraggingDestination defines. Send NSDraggingInfo messages to this object. You never need to create a class that implements the NSDraggingInfo protocol.
