# updateProperties()

Configures the view’s content and styling properties before layout.

```
func updateProperties()
```

## Overview

Override this method to configure content and styling in your view subclass. Don’t call this method directly; instead, call [`setNeedsUpdateProperties()`](/documentation/UIKit/UIView/setNeedsUpdateProperties()) to schedule an update.

This method supports automatic observation tracking. For more information, see [Updating views automatically with observation tracking in UIKit](/documentation/UIKit/updating-views-automatically-with-observation-tracking-in-uikit).
