I'm a little embarrassed to admit, but I had been blissfully unaware that View extensions are type erasing.

That means if you have an extension for using your ViewModifier in a more ergonomic way, it'll be erased to AnyView unless you explicitly mark it as @inlinable.

Edit: Perhaps this is just a quirk of Xcode Previews: https://mastodon.notsobig.co/@phill/111051676536041177

@phill this is extremely surprising. Where is the AnyView even coming from!?

@mattiem yes quite surprising! Presumably AnyView is introduced by the runtime?

I thought it made sense, but now I’m not sure it does. 😅
