Magento 2 – Add text swatch attribute value programmatically

i need to add text swatch attribute value through script. I’am able to add the attribute but swatch value is not adding. Below is the code i using –

    $attributeDetails = $objectManager->create('MagentoEavModelConfig')->getAttribute("catalog_product", $attributeCode);
    //print_r($attributeDetails->getId()); exit();
    $attributeId = $attributeDetails->getId();
    $languageValues[0]=$label; 
    $languageValues[1]=$label;
    /* @var $attr MagentoEavModelEntityAttribute */
    $attr = $objectManager->create('MagentoEavModelEntityAttribute'); 
    $attr->load($attributeId); 
    $option = [];
    $option['value'][$languageValues[0]] = $languageValues;
    $attr->addData(array('option' => $option));
    $attr->save();

Here in image test is the value i am trying to create.
Any idea how to do it? Any help would be appreciated. Thanks in advance.
