iOS Getting the speed of a screen swipe

[drf1229]

I was working on an app where a person can throw an object based on the speed of a swipe on the screen. I've tried creating a variable that grows each time the touchesMoved method is called, but touchesMoved is called more times if the swipe is slower and less times if the swipe is quicker. Is there any other way to tell the speed of a swipe on the screen? Any advice is greatly appreciated!

Take the distance the touch moved in a certain interval. The further the distance traveled the faster the swipe.
