If you were to use the C library then this could be done   time t t  struct tm   timeinfo   time   amp t   timeinfo   localtime   amp t    NSLog   Hour   d Minutes   d   timeinfo- gt tm hour  timeinfo- gt tm min     And using Swift   var t   time t   time  amp t  let x   localtime  amp t   println  Hour    x memory tm hour  Minutes    x memory tm min      For further guidance see  http   www cplusplus com reference ctime localtime
