How to make an animated image zoom out in a PageViewController?

Question

Swift

There is a PageViewController that scrolls left and right. There is a photo on the first page. It is necessary that when scrolling to the second page, the photo smoothly decreases. That is, the further I scroll, the more the picture decreases.
I can only make an animation when I have completely moved to the second page, but to reduce the picture in the process of turning over is an impossible task for me. Tell me how to do it?

Answer 1

To do this, use a collection with a custom layout. PageController won't work.
