This was one of the things I was wondering about. Vuetify is one of the bigger libs for Vue2 so if I were to do some upgrades it would need to be ready.
I tried Vuetify with Vue 3 about a month ago in case it was "semi-ready" and lots of basic functionality was still missing.
As much as I love working in Vue, Vuetify is the entire reason I use Vue today: if there were a Vuetify for Svelte I'd be using that instead.
All the Svelte component libraries, and indeed all component libraries I've ever tried, pale in comparison to Vuetify. With perhaps the exception of Quasar.
Using Tailwind after Vuetify feels like going from writing C# to assembly.
