Как правильно использовать Di container component symfony?

Question

[kaxa3201]

Почему-то не срабатывает Di container, правильно ли я реализовал?
bootstrap.php

$container = new ContainerBuilder();
$loader = new DiYamlFileLoader($container, new FileLocator(__DIR__));
$loader->load('../config/services.yaml');
$container->compile();

services.yaml

services:
  _defaults:
    autowire: true
    autoconfigure: true
    public: false
  App\:
    resource: ../app/
    exclude: ../app/[a-z]*

  dependent.service:
    class: 'App\Interfaces\Services\ReportServiceInterface''
  demo.service:
    class: 'App\Generators\ReportGenerator'
    arguments: ['@dependent.service']

ReportGenerator

public function __construct(ReportServiceInterface $reportService)
    {
        $this->reportService = $reportService;
    }
