> It stands to reason that Apple wouldn't have developed this feature if they weren't using it. Where? We have no idea. But they must be using it somewhere. The fact that none of us have noticed exactly where suggests that we're interacting with webviews in our daily use of iOS without ever even realising it.

This is what stood out to me. I've never really suspected webviews and can't think of a place now.

I often suspect things in Settings, esp. account/iCloud section to be webviews, just based on how they load (icons appearing a short moment after the page opens for example).

Yes, those parts of the Settings app are built with web views that embed React Web:

Oh so that's why they're terrible and often break with no error messaging or recourse

Probably, but it’s not as if the native parts of Settings are much better.

When you tap some of the menu items in the “Saved to iCloud” section, they don’t have the normal grey item highlight that happens with the rest of the settings app.

The App Store app seems to be using web views extensively.

It is not. Apple made a big deal about the changeover a few years back.

Both Mail and Calendar use web views for starters.

I assume they're going to use it on Apple.com, the same way that they were using backdrop-filter to simulate the frosted glass on earlier iOSes

according to the post, it doesn't exist on Safari

I’m fairly certain Apple Music makes pretty heavy use of webviews.

Actually it does not. It used to, but then was rewritten. The Accessibility Inspector app can be used to see what's the class of the UI elements, if you want to check.

I think it still might. I use it all the time on my laptop, and periodically if I do something funky with the network, the entire view panel says that there was an internal server error in that classic no-CSS Times New Roman font. Do you have a source for this?

As I wrote above, use Accessibility Inspector to inspect the UI.

I’m sure there are many apps like the Apple Store app and parts of the App Store that pull in web views. That’s most likely what this is for. Probably parts of News, Music, Games apps as well.
