Trying the above code is causing a warning error to be thrown with my usage and I don’t understand why.
Warning: Invalid argument supplied for foreach()

<?php
    $portfolioContent = get_field('portfolio_content'); // this is the group field
    if ($portfolioContent) :
        $skills = $portfolioContent['skills'];
        $field = get_field_object($skills);
    ?>
        <h1><?php echo $subTitle; ?></h1>
        <?php
        if ($skills) : ?>
            <ul>
                <?php foreach ($field['choices'] as $v => $l) : ?>
                    <li><?php echo $l; ?></li>
                <?php endforeach; ?> 
            </ul>
        <?php endif;

        ?>
    <?php endif;
?> 

$skills = the checkboxes

print_r($skills); 
// return value = value
Array ( [0] => wordPress [1] => javascript [2] => jquery [3] => scss [4] => responsive-design [5] => photoshop [6] => illustrator )

// return value = both
Array ( [0] => Array ( [value] => wordPress [label] => WordPress ) [1] => Array ( [value] => javascript [label] => Javascript ) [2] => Array ( [value] => jquery [label] => jQuery ) [3] => Array ( [value] => scss [label] => SCSS ) [4] => Array ( [value] => responsive-design [label] => Responsive Design ) [5] => Array ( [value] => photoshop [label] => Photoshop ) [6] => Array ( [value] => illustrator [label] => Illustrator ) )
