I like skeuomorphism, I hope it comes back.

But the best UI is custom. It would be better if apps had themable UIs so users could apply custom themes if they want to make all their apps have a particular style (e.g. metal, sepia, colorful, modern). Because then the UI can be skeuomorphic or minimal or anything else.

Apple has recently been adding more UI customization. There were custom lock screens in iOS 17, custom app icons in iOS 18, and something's planned for iOS 19. It hasn't gotten much attention, maybe in part because there's still a lot you can't customize (especially in most non-Apple apps), more likely because Android is still even more customizable (especially because it's not as locked down). But Apple doing it is significant because they could start a more widespread trend.
