How to show ~year(s) ~month(s) ~day(s) has been passed using NSdate- swift IOS : <p>I'm playing with swift. I want to show how many years/months/days has been passed since the specific date(NSdate). </p>

<p>If the specific date is 08/01/2016 and current date is 08/11/2016, it will show only "10day(s) has been passed". If the specific date is 08/11/2015, it will show "1year(s) 0 month(s) 0day(s)has been passed"</p>
