Get wishlist collection of a customer by customer id Magento 2.

You can get wishlist collection of a customer by customer id. You can show detail of Customer Wishlist item in a store. Get Wishlist collection by calling Magento\Wishlist\Model\Wishlist Model file.

I have created a Block file for define Wishlist collection and load collection in template file by iterating over a collection loop.

namespace Rbj\Wishlist\Block;

class Demo extends \Magento\Framework\View\Element\Template
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Wishlist\Model\Wishlist $wishlist,
        array $data = []
    ) {
        $this->wishlist = $wishlist;
    * @param int $customerId
    public function getWishlistByCustomerId($customerId)
        $wishlist = $this->wishlist->loadByCustomerId($customerId)->getItemCollection();

        return $wishlist;

Call function in a template file, If Customer has wishlist item available, display item info otherwise no item found message will be displayed.

$customerId = 2; //CUSTOMER_ID
$wishlistCollection = $block->getWishlistByCustomerId($customerId);
if(count($wishlistCollection)) {
    foreach ($wishlistCollection as $_item) {
        echo $_item->getProduct()->getName();echo "<br>";
        echo $_item->getProduct()->getId();echo "<br>";
} else {
    echo __("No Item found in your wishlist");

The result will be your Item list from a Wishlist.
