A user field always holds an array of user IDs. This might change if you only allow one user to be selected, but I don’t think so. You must still loop over the even when you are returning IDs.

$users = get_field('user_field_name');
// just in case it has a single value
if (!is_array('$users') && !emapty($users)) {
  $users = array($users);
}
if ($users) {
  foreach ($users as $user_id) {
    // do something with user id
  }
}
