В Symfony 2 получено сообщение об ошибке типа Fatal error: Class ...\Controller\Swift_SmtpTransport'не найден?

Question

I am  new to Symfony Swift mailer. I have tried the following code bellow to configure the username and password

Но возникла проблема с загрузкой такого класса, как Swift_SmtpTransport.

   $transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465)
                ->setUsername('[e-mail]')
                ->setPassword('yyyyyy');

    $mailer = Swift_Mailer::newInstance($transport);

    $message = Swift_Message::newInstance();

    $body="body-text";
    $subject="subject-text";
    $message->setSubject($subject)
        ->setFrom('[e-mail]')
        ->setTo('[e-mail]')
        ->setContentType('text/html')
        ->setBody($body);
    $result = $mailer->send($message);
    return $result;

Заранее спасибо.

 $transport = \Swift_SmtpTransport::newInstance('smtp.gmail.com', 465)
                ->setUsername('[e-mail]')
                ->setPassword('yyyyyy');

    $mailer = \Swift_Mailer::newInstance($transport);

    $message = \Swift_Message::newInstance();
