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

This one should help you https://kotlinlang.slack.com/archives/C3PQML5NU/p1579685197083900

“-Xobjc-generics” - it’s just a partly solution. See my question about generics. https://kotlinlang.slack.com/archives/C3PQML5NU/p1579344665010100

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.

Managed to work around the interface problem, with

E/A

for the

Observable

and abstract class instead of interface for the

Observer
