The child elements in the accessibility hierarchy.
- macOS 10.10+
This property contains references to child elements in the accessibility hierarchy. If you create an
NSView subclass, you don’t typically need to set this value. The system automatically populates the
accessibility property with descendants in the view hierarchy that are also in the accessibility hierarchy. If you use an
NSAccessibility subclass to represent an interface element that is not backed by a view, you can either set the
accessibility property or you can call the
accessibility convenience method.
