There is a wheel event which you can use to detect two-finger swipe on Mac.

Your code could look something like this:

      $('element').on('wheel', function(e){
        var eo = e.originalEvent;
        if(Math.abs(eo.wheelDeltaY) < 10 && Math.abs(eo.wheelDeltaX) > 2){
          e.preventDefault();

          if(eo.wheelDeltaX < -100 && !scope.item.swipedLeft){
              // swipe left
          }

          if(eo.wheelDeltaX > 100 && scope.item.swipedLeft){
              // swipe right
          }
        }
      });

This could possibly not work in some older browser and/or Mozilla (as it fires some different event for the wheel movement), but as long as you implement this as an additional/helper feature, this code should suffice.
