$this->getContent() of type Iterator is incompatible with the type array expected by parameter $array of array_shift().

        }

        return $this;

The expression return $this returns the type Ticaje\FileManager\Infrastructure\Driver\Traits\FileInterface which is incompatible with the type-hinted return Ticaje\FileManager\Infrastructure\Driver\Reader\Interfaces\FileInterface.
