Use Applescript In Xcode To Make Timer In Window

Answer 1

One way would be to create a countdown handler using performSelector:withObject:afterDelay: to repeatedly count down, putting the current value into your text field.  For example, using countdownText as your text field and countdownTime as the value to count down:
on countdown()
  set countdownTime to countdownTime - 1
  if countdownTime is less than 0 then -- clear timer and reset
  parent's cancelPreviousPerformRequestsWithTarget_selector_object_(me, "countdown", missing value)
  countdownText's setStringValue_("") -- clear the countdown text
  -- reset countdownTime value and do whatever when countdown ends
  else -- do it again
  countdownText's setStringValue_(countdownTime) -- update the countdown text
  performSelector_withObject_afterDelay_("countdown", missing value, 1.0)
  end if
end countdown
