You need to create a custom Twig extension in order to make this function known inside your templates. Please see https://gist.github.com/rgasch/5c7f76c0e953f6782478420bb4c1da57 for an example of how to do this.

You can do this with the addGlobal function on the Twig instance.

$view = $app->getContainer()['view'];
$view->getEnvironment()->addGlobal('url', function ($url) {
    return url($url);
});
