Answer 1

changed to use

    \Magento\Wishlist\Model\Wishlist $wishlistModel

....

        $wishlist = $this->wishlistModel->getCollection()->addFieldToFilter('customer_id', $customer_id);
        //var_dump($wishlist);
        foreach ($wishlist as $list) {
            echo $list->getId().'__'.$list->getName()."<br>";
        }
