# applicationAccessibilityEnabledDidChangeNotification

Posted when the value returned by `AXApplicationAccessibilityEnabled()`
changes.

```
static let applicationAccessibilityEnabledDidChangeNotification: NSNotification.Name
```

## Discussion

Posted on the main thread. The notification’s `object` is `nil` and
its `userInfo` dictionary is empty — clients should re-read
`AXApplicationAccessibilityEnabled()` when handling the notification.
