Answer 1

try to override the file Magento\ConfigurableProduct\Model\AttributeOptionProvider.php

in your module and put below code before the return in the function getAttributeOptions.

usort($data, function($a, $b) {
        return $a['option_title'] <=> $b['option_title'];
});

I hope this will help you!!

Answer 2

In v2.3.x you can sort the order of the attributes by option label in a configurable product drop down selector by extending

Magento\ConfigurableProduct\Model\AttributeOptionProvider

and using

usort($data, function($a, $b) {
    return $a['option_title'] <=> $b['option_title'];
});

To sort the returned option data array $data in method getAttributeOptions() for a specific attribute i.e. color use

/**
* {@inheritdoc}
*/
public function getAttributeOptions(AbstractAttribute $superAttribute, $productId)
{
   $scope  = $this->scopeResolver->getScope();
   $select = $this->optionSelectBuilder->getSelect($superAttribute, $productId, $scope);
   $data = $this->attributeResource->getConnection()->fetchAll($select);

   $sortByOptionTitle=false;

   if ($superAttribute->getSourceModel()) {
       $options = $superAttribute->getSource()->getAllOptions(false);

       $optionLabels = [];
       foreach ($options as $option) {
           $optionLabels[$option['value']] = $option['label'];
       }

       foreach ($data as $key => $value) {
           $optionText = isset($optionLabels[$value['value_index']])
               ? $optionLabels[$value['value_index']]
               : false;
           $data[$key]['default_title'] = $optionText;
           $data[$key]['option_title'] = $optionText;

           if (isset($data[$key]['attribute_code']))
           {
               if ($data[$key]['attribute_code']=='color')
               {
                   $sortByOptionTitle=true;
               }
           }
       }

       if ($sortByOptionTitle)
       {
           usort($data, function($a, $b) {
               return $a['option_title'] <=> $b['option_title'];
           });
       }
   }

   return $data;
}
