Dumb question but Apple’s apps are buttery smooth. I just assumed they were using swift and not a web stack to render their UI. Am I completely wrong?!

This is the source for the web version of the app store

which is definitely not buttery smooth, I use it every day

It only came out yesterday.

App Store Connect did not come out yesterday

I see no contradiction here.

Source?

Apple Music is not buttery smooth and was just a web view for a long time. I feel like I read that this changed a few years ago. This didn’t change the fact that it’s very slow.

The iTunes Store, which was embedded in iTunes, sure was a webview, but I don't think Apple Music ever was a webview?

(Except maybe the "Home"/"For Me" pages which are just "discovery page" extensions of the store and the Apple Music service that's built on top of it)

The macOS one descends from iTunes and the iOS one descends from the original iPhone which sure as hell wasn't a webview.

It was, you often could see JS error messages or weird rendering errors / flickering (Also some other mentions: https://news.ycombinator.com/item?id=20892650).

There's also some parts of System Settings that were always web views, which I always found surprising for a company trying to make the case for native apps.
