Answer 1

$.ajax({
 url: '/ajax/xyz.json'
})
.done(function( data ) {
  $('#id').autocomplete({
    source: data,
    open: function( event, ui ) {
        if (navigator.userAgent.match(/(iPod|iPhone|iPad)/)) {
          $('.ui-autocomplete').off('menufocus hover mouseover mouseenter');
        }
    },
    select: function( event, ui ) {
      window.location.href = ui.item.value;
      return false;
    }
  });
});

This worked for me (works on drupal 8 as well). Now one tap on iOS devices redirect to search result page.
