I'm noticing that if I pause a fast moving `UIViewPropertyAnimator` it jumps back a frame which is... not great.

is there a way around that? am i doing something wrong? or just a tradeoff for the the way this api works?

(context: I have a box moving from one point on the screen to another, and on `touchesBegan` I pause the animator to "catch" the box. because of the frame jump, it then feels off)

Here's a frame by frame video. Note the sudden snap back.

It's visually ahead a frame but pausing the animator puts it back a frame

@edwellbrook I just realised the same thing happens in the player transition in Soor. I knew something looked off but didn’t think much of it. I’ll investigate this and report back if I find a solution.

@tanmay Which version of iOS is this running in?

My video was pulled from latest 16.5 beta. I haven't checked individual frames yet, but maybe seems OK in 16.4 simulator. 🤷‍♂️

I'm thinking I'll file a radar

@edwellbrook This is from a 14 Pro Max running on 16.5. I haven’t debugged this yet, only ran my app to verify the behaviour but it’s likely the same thing which you figured out. I’ll dig a bit into this later and file a radar as well.
