I have use events and observers to check the whther the user is logged in or not. And the logout user will not see the price of the product. Here's my code:

<?xml version="1.0" encoding="UTF-8"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/Event/etc/events.xsd">
        <event name="layout_load_before">
            <observer name="add_layout_handles" instance="Demo\Mymodule\Observer\AddHandles" />
        </event>
    </config>

Created Addhandles.php in app/code/Demo/Mymdoule/Observer:

<?php

namespace Demo\Mymodule\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Customer\Model\Session as CustomerSession;

class AddHandles implements ObserverInterface
{
    /**
    * @var CustomerSession
    */
    protected $customerSession;
    /**
    * Add constructor.
    * @param CustomerSession $customerSession
    */
    public function __construct(CustomerSession $customerSession)
    {
        $this->customerSession = $customerSession;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $layout = $observer->getEvent()->getLayout();


        if (!$this->customerSession->isLoggedIn())
        {
            $layout->getUpdate()->addHandle('customer_log_out');
        }
    }
}

Created customer_log_out.xml in app/code/Demo/Mymodule/view/frontend/layout:

<?xml version="1.0"?>
<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
    <referenceBlock name="render.product.prices">
        <arguments>
            <argument name="default" xsi:type="array">
                <item name="prices" xsi:type="array">
                    <item name="final_price" xsi:type="array">
                        <item name="render_template" xsi:type="string">Demo_Mymodule::product/price/final_price.phtml</item>
                    </item>
                </item>
            </argument>
        </arguments>
    </referenceBlock>
</layout>

Created final_price.phtml in app/code/Demo/Mymodule/view/frontend/templates/product/price which have my custom message.

But it's not working. Can please someone help me.

Override class:

\Magento\Catalog\Pricing\Render\FinalPriceBox

And in that override method:

public function wrapResult($html)

and in that you can get product attribute like:

if($this->getSaleableItem()->getXyzIsHide()) { return ""; } else { ... }
