IOS Safari transition transform not working - css

Question

Whenever I seem to apply some code to let's say move a div for example using the latest iOS Safari browser it doesn't actually transition between the two rules set. I have tried changing to use other than percentage values but still to this day, I have never been able to get it to work when I use transition: transform; for any translate property applied.
I'm using the correct prefixes and checked support and should be working no problem.

JSFiddle
$('button').on('click', function() {
$('.mydiv').toggleClass('added-class');
});
.mydiv {
display: inline-block;
width: 100px;
height: 50px;
background-color: red;
-moz-transform: translateY(0);
-ms-transform: translateY(0);
-o-transform: translateY(0);
-webkit-transform: translateY(0);
transform: translateY(0);
-moz-transition: transform 0.6s ease-out;
-o-transition: transform 0.6s ease-out;
-webkit-transition: transform 0.6s ease-out;
transition: transform 0.6s ease-out;
}
.added-class {
-moz-transform: translateY(100%);
-ms-transform: translateY(100%);
-o-transform: translateY(100%);
-webkit-transform: translateY(100%);
transform: translateY(100%);
}

Old versions of iOS Safari support only vendor-prefixed properties and values for transition and transform, so you should use -webkit-transition: -webkit-transform instead -webkit-transition: transform:

$('button').on('click', function() {
$('.mydiv').toggleClass('added-class');
});
.mydiv {
display: inline-block;
width: 100px;
height: 50px;
background-color: red;
-webkit-transform: translateY(0);
-moz-transform: translateY(0);
-ms-transform: translateY(0);
-o-transform: translateY(0);
transform: translateY(0);
-webkit-transition: -webkit-transform 0.6s ease-out;
-moz-transition: transform 0.6s ease-out;
-o-transition: transform 0.6s ease-out;
transition: transform 0.6s ease-out;
}
.added-class {
-webkit-transform: translateY(100%);
-moz-transform: translateY(100%);
-ms-transform: translateY(100%);
-o-transform: translateY(100%);
transform: translateY(100%);
