Usage The control itsself is TenClock. Add that to your view hierarchy, and constrain it to be square (thats kindof important). to set times, do:

self.tenClock.startDate = NSDate()
self.tenClock.endDate = NSDate. //sometime later

make the date today. then, to get updates for when the date changes, adopt the protocol TenClockDelegate and observe:

import TenClock
class ViewController: UIViewController, TenClockDelegate {
    func timesChanged(clock:TenClock, startDate:NSDate,  endDate:NSDate  ) -> (){
        print("start at: \(startDate), end at: \(endDate)")
        self.beginTimeLabel.text = dateFormatter.stringFromDate(startDate)
        self.endTimeLabel.text = dateFormatter.stringFromDate(endDate)
    }
    // ...
