IOS Safari transition transform not working

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%);
