This first one – in response to pressing the volume buttons – feels world-class. Subtle responses to buttons being pressed, nice haptics, good physics:

This one – stretching of the control center – made me incredulous. The performance and physics of it all feels fluid, but this feels like absolutely the wrong thing to do here. I think it’s as designed, but it feels buggy to me. Maybe I’m oversensitive to stretching type and shapes like this, but I can’t stand how icky it feels. I am not sure I have seen another place in iOS 26 where elements would stretch in such a cheap way:

And this one – tapping on the album cover to make it show and hide – is bad in perhaps every possible way. It feels designed poorly and engineered poorly, like an HTML approximation of a real thing. All sorts of bad curves and sudden switches, slight reorientations of UI, even some flickering of interface elements at the bottom. It feels so rough I would probably just do a hard switch, no transition, until I got this right. After all, no animation is better than bad animation, and this is not responding to fingers in real time (when the user controls the “speed,” and you absolutely need a transition):

Ultimately I don’t know if this is “as designed,” or rushed, or what are the causes. But It’s interesting and a bit hard to realize that these days even animations in iOS 26 – once, I believe, a staple of good design and execution – are all over the place.
