Why Symfony doesnt autowire mailer, router?

Im using Symfony 4. I want to use Router and mailer in my services. I am including them using Dependency injection.

public function __construct(Swift_Mailer $mailer, EngineInterface $templating, RouterInterface $router)
{
    $this->mailer = $mailer;
    $this->router = $router;
    $this->templating = $templating;
}

I am getting this error: 

argument "$templating" of method "__construct()" references interface "Symfony\Component\Templating\EngineInterface" but no such service exists. It cannot be auto-registered because it is from a different root namespace. Did you create a class that implements this interface?

Any hint to use Mailer, Router services in Symfony 4 ?

Change the TypeHint and use Interface, the autowire work with interface type hint

try this :

public function __construct(Swift_Mailer $mailer, \Twig_Environment $templating, RouterInterface $router)

I had to composer require symfony/templatingin order to get the Symfony\Bundle\FrameworkBundle\Templating\EngineInterface service.

Also the following configuration has to be added under framework:

templating: enabled: false engines: ['twig']
