How to get product manufacturer swatch image?

Question

I have next string, where I get manufacturer attribute:

$brand = $currentProduct->getResource()->getAttribute('manufacturer');

I need to get attribute swatch image. How can I get it?

On product filters I got it:

                        <img class="object-fit-contain w-100 h-100"  src="<?=
                    $objectManager->get('Magento\Store\Model\StoreManagerInterface')
                            ->getStore()
                            ->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA).'attribute/swatch/'.
                    $swatchData['swatches'][$option]['value']?>" alt="<?= /* @escapeNotVerified */ $label['label'] ?>">

Answer 1

Grab all swatches from attributes

$brand_code="manufacturer";
$brandValue = $objectManager->get('Magento\Catalog\Model\Product')->load($_product->getId())->getData($brand_code);
$swatchHelper=$objectManager->get("Magento\Swatches\Helper\Data");
$swatchData = $swatchHelper->getSwatchesByOptionsId([$brandValue]);

Displaying image:

<img class="object-fit-contain w-100 h-100"  src="<?=
$objectManager->get('Magento\Store\Model\StoreManagerInterface')
    ->getStore()
    ->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA).
    'attribute/swatch'.$swatchData[$brandValue]['value']?>" alt="brand"/>
