Answer 1

Using constructor dependency injection (tested with Symfony 3.4):

class MyService
{
    private $mailer;
    private $templating;

    public function __construct(\Swift_Mailer $mailer, \Twig_Environment $templating)
    {
        $this->mailer     = $mailer;
        $this->templating = $templating;
    }

    public function sendEmail()
    {
        $message = $this->templating->render('emails/registration.html.twig');

        // ...
    }
}

No need to configure arguments.
