<?php

// Getting the array
$product_group = rwmb_meta( 'products' );

/**
 * Keys =
 * $product_group = rwmb_meta( 'products');
 * 'sw_swsku';
 * 'sw_swdescription';
 * 'sw_swprice';
 * 'sw_swqty';
 */

/**
 * Notice that the array has indexes like 0, 1,...
 *
 * For an ordered array, you can simply loop based on count...

 */

for ( $i = 0; $i <= count( $product_group ); $i ++ ) { ?>
	<div class="field-sku"><?php echo $product_group[ $i ]['sw_swsku']; ?></div>
	<div class="field-description"><?php echo $product_group[ $i ]['sw_swdescription']; ?></div>
	<div class="field-price"><?php echo (float) $product_group[ $i ]['sw_swprice']; ?></div>
	<div class="field-qty"><?php echo (int) $product_group[ $i ]['sw_swqty']; ?></div>
<?php }


/**
 * If you want to stick to the foreach, keep in mind that in an ordered array, you'll just want to do...

 */

foreach ( $product_group as $product ) { ?>
	<div class="field-sku"><?php echo $product['sw_swsku']; ?></div>
	<div class="field-description"><?php echo $product['sw_swdescription']; ?></div>
	<div class="field-price"><?php echo (float) $product['sw_swprice']; ?></div>
	<div class="field-qty"><?php echo (int) $product['sw_swqty']; ?></div>
<?php }
