Why does swipe up on a UITableView run the cellForRowAt function each time?

I have a UITableView that when the function cellForRowAt is called some calculations are being made. This all works great until I found out that when I swipe up on the tableview, the cellForRowAt function is called each time. Is this a bug in iOS 11 (GM) or something that should be happening? If this is default behavior is it possible to deactivate the swipe up gesture?

It's because you use

dequeueReusableCell

in cellForRowAt.UITableView redraw cells that not display on screen every time when you swipe up or down.

Whenever we scroll down or up cellForRowAt will be called due to intraction and change in behaviour of UITableView and whwn changes happend then cell has to redesign its self.
