  let authenticationContext = LAContext()
        var error: NSError?</p>

<pre><code>    if authenticationContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &amp;error) {
        authenticationContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason:"Not let  somebody else", reply: { (success, error)   in

            if success {
                self.navigateToAuthenticatiedVC()
            } else{
                if let error = error as? NSError {
                    let message = self.errorMessageForErrorCode(errorCode: error.code)
                    self.showAlertViewAfterEvaluatingPolicyWithMessage(message: message)
                }
            }

        })
