Is there a way to expose arrays with explicit type from the common? Currently I’m getting my List<SomeModel> converted to NSArray with losing the information about it’s type, SomeModel

“-Xobjc-generics” - it’s just a partly solution. See my question about generics.

Ah, I see @Olenyov Kirill. So this is a Swift <-> Objc interop problem. Actually I have an Observable<List<SomeModel>> and my use-case is the same as yours with test2

I wrote the generics implementation. There are restrictions imposed by objective-c, such as you can’t have generics on interfaces (protocol in objc). Collection types have special handling in both objc->swift and in how the headers are generated from kotlin. In many general cases they work. You can certainly find cases where generic types are dropped as well.

Observable is an interface. It will not retain generics. That’s an objc problem.

Managed to work around the interface problem, with E/A for the Observable and abstract class instead of interface for the Observer
