		"touchstart": {"x":-1, "y":-1}, 
		"touchmove" : {"x":-1, "y":-1}, 
		"touchend"  : false,
		"direction" : "undetermined"
	},
	touchHandler: function(event) {
		var touch;
		if (typeof event !== 'undefined'){	
			event.preventDefault(); 
			if (typeof event.touches !== 'undefined') {
				touch = event.touches[0];
				switch (event.type) {
					case 'touchstart':
					case 'touchmove':
						swipeFunc.touches[event.type].x = touch.pageX;
						swipeFunc.touches[event.type].y = touch.pageY;
						break;
					case 'touchend':
						touches[event.type] = true;
						if (swipeFunc.touches.touchstart.x > -1 && swipeFunc.touches.touchmove.x > -1) {
							swipeFunc.touches.direction = swipeFunc.touches.touchstart.x < swipeFunc.touches.touchmove.x ? "right" : "left";
							
							// DO STUFF HERE
							alert(touches.direction);
						}
					default:
						break;
				}

Throws error on iPad iOS 9.2 on line 21!
ReferenceError: Can't find variable: touches

You should use "swipeFunc.touches" rather than "touches" in lines 21 and 26. Also I had to comment out line 11 (event.preventDefault()) to avoid disabling browser scrolling.

This is perfect.

But on some of the andorid devices doesn't able to get the touchend event when we not using the event.preventDefault(). Can you please help ?
