The default value of this property is NSLayoutConstraint.Attribute.bottom, which means that the accessory view should display below the title bar. You can also set this property to NSLayoutConstraint.Attribute.right or (in apps linked on macOS 10.11 or later) NSLayoutConstraint.Attribute.left. All other values are invalid and will cause an assertion to be raised.
