1. try
   loader engine

        '.twig' => function($view, $di) {
            @mkdir(APP_PATH . '/cache/twig/' . APP_ENV);
            $options = array();
//            if (APP_ENV == 'prod')
//                $options = array('cache' => APP_PATH . '/cache/twig/' . APP_ENV );
            return new TwigEngine($view, $di, $options);
        }

main view path: view/admin/index.php

        <div class="container">
            {% block content %}{% endblock %}
        </div>

action view path: view/admin/login/index.php

{% extends "index.twig" %}

{% block content %}
    test
