I’m pretty sure when the Ladybird team said “Swift has strictly better OOP support”, they were not referring to ObjC style message passing, so it’s not even relevant.

I'm pretty sure your guessing is silly. I assume you are trying to be here in good faith, so make your case. Since it is not support for message passing, what else makes Swift have "strictly better OOP support"?
That's the thing man, there isn't anything. It was an odd thing in the tweet to say that it has better OOP.
(source: iOS dev from jailbreak days, so like 8 years before Swift, till 2019. He did not mean dynamic dispatch and Swift has dynamic dispatch by way of "you can annotate a Swift method with @objc and we'll emit it as an ObjC method instead of Swift", not Smalltalk-ish, like, at all. if you're the poster who originally said "because of dynamic dispatch", I understand why you're frustrated but I have 0 idea why you think dynamic dispatch in Swift would matter, much less say it makes Swift much better at OOP than Rust. It's impolite to say "utterly baffling engineering decision" in public, so there's subtext in the conversation. Namely that both claims made 0 sense if you had practical familiarity with either)

But that's the thing, there is: It supports message passing.
Like we already discussed long ago, it supports it poorly, and only for the sake of compatibility with Objective-C, but still that makes its OOP support better than Rust's. Rust has no OOP support at all. It is not an OOP language and never would want to be. OOP goes completely against its core principles (statically-typed, performance-minded).
Realistically, nobody would consider Swift an OOP language either. However, on the spectrum, it is unquestionably closer to being an OOP language. It at least gets an honourable mention in the short list of OOP languages. It is undeniable that Swift has "better" OOP support; not to be confused with good OOP support.
> He did not mean dynamic dispatch
Of course not. Dynamic dispatch is for function calling. OOP doesn't use dynamic dispatch. That's literally why we call it object-oriented rather than function-oriented (or functional, as the kids say). This is also why Objective-C, quite brilliantly, uses [foo bar] syntax (hint: it kind of looks like an ASCII-art envelope for a reason): To make it clear that conceptually you are not calling a function.

I don't. Fill us in.
