    LAContext *context = [[LAContext alloc] init];
    __block  NSString *msg;
    [context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:NSLocalizedString(@"Place your finger on the sensor", nil) reply: ^(BOOL success, NSError *authenticationError) {
         if (success) {
         }

@IBAction func touchidbutton(sender: AnyObject) {
    authContext.evaluatePolicy(LAPolicy.DeviceOwnerAuthenticationWithBiometrics, localizedReason: "Place your finger on the sensor"?, reply: ((success : Bool, NSError!) -> Void)?){
        if (success) {
        }
    }
}
