# restorationClass

The class responsible for recreating this view controller when restoring the app’s state.

## Declaration

```swift
var restorationClass: (any UIViewControllerRestoration.Type)? { get set }
```

About the UI restoration process

## Discussion

Discussion If a view controller has an associated restoration class, the viewController(withRestorationIdentifierPath:coder:) method of that class is called during state restoration. That method is responsible for returning the view controller object that matches the indicated view controller. If you do not specify a restoration class for your view controller, the state restoration engine asks your app delegate to provide the view controller object instead. The restoration class must conform to the UIViewControllerRestoration protocol.
