# backgroundConfiguration

The current background configuration of the view.

```
@MainActor @preconcurrency var backgroundConfiguration: UIBackgroundConfiguration? { get set }
```

## Discussion

Using a background configuration, you can obtain system default background styling for a variety of different view states. Create a background configuration with one of the default system styles, customize the configuration to match your view’s style as necessary, and assign the configuration to this property.

```swift
var backgroundConfig = UIBackgroundConfiguration.listPlainHeaderFooter()
backgroundConfig.backgroundColor = .systemGray
header.backgroundConfiguration = backgroundConfig
```

A background configuration is mutually exclusive with background views, so you must use one approach or the other. Setting a non-`nil` value for this property resets the following APIs to `nil`:

- [`backgroundColor`](/documentation/UIKit/UIView/backgroundColor)
- [`backgroundView`](/documentation/UIKit/UITableViewHeaderFooterView/backgroundView)
