title: How to programmatically check support of 'Face Id' and 'Touch Id'
body: <p>I've integrated <a href="https://developer.apple.com/documentation/localauthentication" rel="noreferrer">LocalAuthentication</a> for my app security purpose, which has been supporting <strong>'Touch Id'</strong> based supporting. But now, apple has recently added <strong>'Face Id'</strong> based authentication also.</p>
  
  <p>How can I check, which type of authentication is supported by a device. Touch Id or Face Id?</p>
