# WebViewProgressStarted

Posted by a WebView object when a load begins, including a load that is initiated in a subframe.

```
static let WebViewProgressStarted: NSNotification.Name
```

## Discussion

The notification object is the WebView that began loading. This notification does not contain a `userInfo` dictionary.
