# NSAccessibility

A legacy, informal protocol that Apple doesn’t recommend for active use.

## Overview

Overview The NSAccessibility informal protocol defines an old, key-based API. For the most part, Apple doesn’t recommend using this API. Use the method-based API in NSAccessibilityProtocol instead. However, there are a few methods and properties that are still relevant. You can combine the accessibilityHitTest(_:) method, and the accessibilityFocusedUIElement and accessibilityNotifiesWhenDestroyed properties with the new NSAccessibilityProtocol protocol.
