# restorableState

A change that invalidates the restorable state of the view.

## Declaration

```swift
static var restorableState: NSView.Invalidations.RestorableState { get }
```

## Discussion

Discussion Use this invalidation type to call invalidateRestorableState() so that a change in property value invalidates the viewʼs restorable state. This triggers the app to save any information the restoration system needs to restore the current state of the view.
