DualTimer

DualTimer provides a digital stopwatch - TWICE!
Each timer is has Start, Lap, Pause and Reset buttons (which appear as required).
What makes this timer different is that both can be started at the same time.
Because the timers use actual time for their calculations, going into the background (on devices which support this functionality) has no effect and on returning to the foreground the timers resume their previous state.
This version is a complete re-write of the app in Swift, now supporting 64 bit processors as required for modern apps.
