They used to. AppCode was excellent. Fleet kind of supports Swift well enough.

AppCode was abandoned because Apple is impossible to work with and never provided up to date semantics and language definitions for Swift, keeping everything under wraps and making every single Swift release a race to suddenly implement whatever new keyword they made up this week.

Fleet is more of a VSCode. Probably using the LSP these days, and it's good enough if a simple text editor is what you need.

Swift is literally developed in the open, so I don’t think your argument makes sense.

I think the reason they abandoned it was trouble keeping up with new iOS SDK features getting shadow dropped as part of new Xcode betas and iOS devs wanting to immediately prepare their apps to use those features, not anything to do with Swift language releases. Also things like having to recreate interface builder, then support auto layout in it, and then later SwiftUI previews, etc. Again all iOS platform stuff, not Swift language stuff.
