If I wanted to expose a Kotlin interface in Swift ...

If I wanted to expose a Kotlin interface in Swift as AnyObject, what would that be in Kotlin? Any in Kotlin is just Any in swift. Would it be Any?

AnyObject in Swift is the same as the id type in Objective-C. I believe an abstract class in Kotlin should satisfy AnyObject, as Kotlin classes will inherit from the NSObject base class.

Yeah so turned out that just using a random class other than Any worked, which was a bit weird.

[Jeff Lockhart]

Yeah, Any in Swift basically expands on AnyObject from Objective-C. Any class from Objective-C or Swift should satisfy AnyObject. But besides classes, structs, enums, and function types in Swift satisfy Any, a superset of AnyObject.
