namespace Kitodo\Dlf\ViewHelpers;

use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;
use TYPO3Fluid\Fluid\RenderingContextInterface;

The type TYPO3Fluid\Fluid\RenderingContextInterface was not found. Maybe you did not declare it correctly or list all dependencies?

class IsArrayViewHelper extends AbstractViewHelper
{
    /**
     * Register arguments.
     */
    public function initializeArguments()
    {
        parent::initializeArguments();
        $this->registerArgument('variable', 'mixed', 'The variable to check', false, null);
    }

    /**
     * @return bool
     */
    public static function renderStatic(array $arguments, \Closure $renderChildrenClosure, RenderingContextInterface $renderingContext)
    {
        $result = false;

        $variable = $arguments['variable'];
        if (null === $variable) {
            $variable = $renderChildrenClosure();
        }

        if (null !== $variable) {
            $result = is_array($variable);
        }

        return $result;

The expression return $result returns the type boolean which is incompatible with the return type mandated by TYPO3Fluid\Fluid\Core\ViewHelper\ViewHelperInterface::renderStatic() of string.

    }
