# layoutChanged

This notification is posted after the UI changes in a way that requires the attention of an accessibility client. This notification should be accompanied by a `userInfo` dictionary with the key [`uiElements`](/documentation/AppKit/NSAccessibility-swift.struct/NotificationUserInfoKey/uiElements) and an array containing the UI elements that have been added or changed. Post this notification using the [`post(element:notification:)`](/documentation/AppKit/NSAccessibility-swift.struct/post(element:notification:)) function instead of an `NSNotificationCenter` instance.

```
static let layoutChanged: NSAccessibility.Notification
```
