# WKNavigation

An object that tracks the loading progress of a webpage.

```
@MainActor class WKNavigation
```

## Overview

A [`WKNavigation`](/documentation/WebKit/WKNavigation) object uniquely identifies a load request for a webpage. When you ask a web view to load content or navigate to a page, the web view returns a [`WKNavigation`](/documentation/WebKit/WKNavigation) object that identifies your request. As the load operation progresses, the web view reports progress of that operation to various methods of its navigation delegate, passing them the matching [`WKNavigation`](/documentation/WebKit/WKNavigation) object.
