Magento – Magento 2 text swatches sort order not working

I had the same issue and applied the 2nd fix given here: https://stackoverflow.com/questions/27270918/magento-1-9-1-not-sorting-configurable-product-attributes-dropdown-by-position:

[...] copy app/code/core/Mage/Catalog/Model/Resource/Product/Type/Configurable/Attribute/Collection.php to local folder app/code/local/Mage/Catalog/Model/Resource/Product/Type/Configurable/Attribute/Collection.php and apply this patch:

If you are hesitant of copying across a core file to local folder then I can create a quick module, <rewrite> this Collection.php file and just override the _loadPrices() function and introduce this fix.

You just have to copy the core file to app/code/core/Mage/Catalog/Model/Resource/Product/Type/Configurable/Attribute/Collection.php and add the given code - it was line 304 for me.

It worked fine for my size attribute swatches.

You have problems with Javascript:

$('.btn-cart-single').bind("click",function(){  
        re = 1;
        proId = $("#proId").val();
        curQty = $('#qty').val();
        minQty = $('#min_qty_stock').val();
        maxQty = $('#max_qty_stock').val();
        qtyStock = $('#qty_stock').val();
        qtyStock_1 = $('#qty_stock').val();
        if ( manage_stock == 0 ){
            qtyStock = maxQty + 1;
        }
        if( minQty==''&&maxQty==''&&qtyStock=='' ){
            alert('Please, select item');
            return false;
        }....

When you try to test in console ()

        minQty = jQuery('#min_qty_stock').val();
        maxQty = jQuery('#max_qty_stock').val();
        qtyStock = jQuery('#qty_stock').val();

The 3 vars show empty "" Try to check when the elements #min_qty_stock, #max_qty_stock, #qty_stock is filled

<span class="quantity-box">

                    <input type="text" name="qty" id="qty" maxlength="12" value="1" title="Qty" class="quantity-input qty">                     
                    <input type="hidden" id="min_qty_stock" name="min_qty_stock" value="">                      
                    <input type="hidden" id="max_qty_stock" name="max_qty_stock" value="">
                    <input type="hidden" id="qty_stock" name="qty_stock" value="">
                    <input type="button" class="quantity-controls quantity-plus" onclick="$('qty').value=Number($('qty').value)+1" value="">    
                    <input type="button" class="quantity-controls quantity-minus" onclick="if(Number($('qty').value)>1){$('qty').value=Number($('qty').value)-1;}" value="">                    
                </span>
