SWIFT 3 0 solution based roughly on the one above using extensions   extension CMTime     var durationText String       let totalSeconds   CMTimeGetSeconds self      let hours Int   Int totalSeconds truncatingRemainder dividingBy  86400    3600      let minutes Int   Int totalSeconds truncatingRemainder dividingBy  3600    60      let seconds Int   Int totalSeconds truncatingRemainder dividingBy  60        if hours  gt  0           return String format    i  02i  02i   hours  minutes  seconds        else           return String format    02i  02i   minutes  seconds                 Use it with AVPlayer calling it like this    let dTotalSeconds   self player currentTime    playingCurrentTime   dTotalSeconds durationText

Another way would be convert seconds to date and take the components i e seconds  minutes and hour from date itself  This solution has limitation only till 23 59 59

Define  func secondsToHoursMinutesSeconds  seconds   Int  - gt   Int  Int  Int      return  seconds   3600   seconds   3600    60   seconds   3600    60      Use   gt  secondsToHoursMinutesSeconds 27005   7 30 5    or  let  h m s    secondsToHoursMinutesSeconds 27005    The above function makes use of Swift tuples to return three values at once   You destructure the tuple using the let  var       syntax or can access individual tuple members  if need be   If you actually need to print it out with the words Hours etc then use something like this   func printSecondsToHoursMinutesSeconds  seconds Int  - gt         let  h  m  s    secondsToHoursMinutesSeconds  seconds    print     h  Hours    m  Minutes    s  Seconds       Note that the above implementation of secondsToHoursMinutesSeconds   works for Int arguments   If you want a Double version you ll need to decide what the return values are - could be  Int  Int  Double  or could be  Double  Double  Double    You could try something like   func secondsToHoursMinutesSeconds  seconds   Double  - gt   Double  Double  Double      let  hr   minf    modf  seconds   3600    let  min  secf    modf  60   minf    return  hr  min  60   secf

I went ahead and created a closure for this  in Swift 3    let  m  s       secs  Int  - gt   Int  Int  in         return   secs   3600    60   secs   3600    60    299    This will give m   4 and s   59  So you can format that as you wish  You may of course want to add hours as well  if not more information
