title: iOS: Accessibility support for dynamic labels / validation errors?
body: <p>I want to enable accessibility support in my app where i have In-line validation message (e.g As per below screenshot) when user enters something invalid data. My app doesn't show any error message.</p>
  
  <p>What can be best and intuitive way to inform  visual impaired/blind user about wrong data entries. e.g. Username &amp; password mismatch, invalid.</p>
