Thanks for your quick response  Joe,

My question is specific to any native app where checkbox/toggle button
have been used which does not announce the role and unselected state.
is this a WCAG violation in any way?

An example would be, a Remember me checkbox in a login screen (Any 3rd
party iOS native app)
