# overrideUserInterfaceStyle

The user interface style adopted by the view controller and all of its children.

```
var overrideUserInterfaceStyle: UIUserInterfaceStyle { get set }
```

## Discussion

Use this property to force the view controller to always adopt a light or dark interface style. The default value of this property is [`UIUserInterfaceStyle.unspecified`](/documentation/UIKit/UIUserInterfaceStyle/unspecified), which causes the view controller to inherit the interface style from the system or a parent view controller. If you assign a different value, the new style applies to the view controller, its entire view hierarchy, and any embedded child view controllers.
