# WCSessionUserInfoTransfer

Information about in-progress data transfers.

```
class WCSessionUserInfoTransfer
```

## Overview

You don’t create instances of this class yourself. When you begin a data transfer, the system creates a new instance of this class for you. Use the created object to monitor or cancel the transfer as needed.

To initiate a file transfer operation, call the [`transferUserInfo(_:)`](/documentation/WatchConnectivity/WCSession/transferUserInfo(_:)) or [`transferCurrentComplicationUserInfo(_:)`](/documentation/WatchConnectivity/WCSession/transferCurrentComplicationUserInfo(_:)) method of your app’s [`WCSession`](/documentation/WatchConnectivity/WCSession) object.

## Topics

### Getting the Transfer Information

[`currentComplicationInfo`](/documentation/WatchConnectivity/WCSessionUserInfoTransfer/isCurrentComplicationInfo)

A Boolean indicating whether the data is related to the app’s complication.

[`userInfo`](/documentation/WatchConnectivity/WCSessionUserInfoTransfer/userInfo)

The data being transferred.

### Managing the Transfer Operation

[`transferring`](/documentation/WatchConnectivity/WCSessionUserInfoTransfer/isTransferring)

A Boolean value indicating whether the data is still being transferred.

[`-  cancel`](/documentation/WatchConnectivity/WCSessionUserInfoTransfer/cancel())

Cancels the data transfer.
