There is a typo. It should be `View`, like the alias `use Slim\Views\Twig as View;`

_**Entry “App\Controllers\WelcomeController” cannot be resolved: Entry “Slim\Views\Twig” cannot be resolved: Entry “Twig\Loader\LoaderInterface” cannot be resolved: the class is not instantiable Full definition: Object ( class = #NOT INSTANTIABLE# Twig\Loader\LoaderInterface lazy = false ) Full definition: Object ( class = Slim\Views\Twig lazy = false \_\_construct( $loader = get(Twig\Loader\LoaderInterface) $settings = (default value) array ( ) ) ) Full definition: Object ( class = App\Controllers\WelcomeController lazy = false \_\_construct( $views = get(Slim\Views\Twig) ) )**_

Then you have to add a container definiton for `Twig::class`, e.g.

```php
use Slim\Views\Twig;
use Psr\Container\ContainerInterface;
// ...

return [
    // ...
    Twig::class => function (ContainerInterface $container) {
        $settings = $container->get('settings')['twig'];
        $twig = Twig::create($settings['paths'], $settings['options']);

        return $twig;
    },

    // ...   
];

```
