  There’s a whole bunch of frameworks that are Swift only like SwiftUI, WidgetKit, SwiftData, MusicKit, SharePlay, DeviceActivity and others and can’t be called from ObjC

    But you can write Swift code that can be called from objc, right? Could you write a wrapper/shim in Swift for "object c" that you'd then call using the method outlined in the article?

      You can yeah. With Apple’s older frameworks, you could use either though. It just shows that they’re gradually moving away from ObjC

Could you write a wrapper/shim in Swift for "object c" you could, but there are some things that are harder to represent such as structs and complex enums (since everything "objective" in obj-c is a reference), or even async/await based api's (perhaps with lots of black-based wrappers?)
