 //just paste this 
 let authButton = DGTAuthenticateButton(authenticationCompletion: { (session, error) in
        if (session != nil) {
            // TODO: associate the session userID with your user model
            let message = "Phone number: \(session!.phoneNumber)"
            let alertController = UIAlertController(title: "You are logged in!", message: message, preferredStyle: .alert)
            alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: .none))
            self.present(alertController, animated: true, completion: .none)
        } else {
            NSLog("Authentication error: %@", error!.localizedDescription)
        }
    })
    authButton?.center = self.view.center
    self.view.addSubview(authButton!)
 }
