👋 any known workaround to this K/N problem? Let’s say I have a function like this fun foo(map: Map<String, SomeDataClass?>)
When I try to use it from Swift, SomeDataClass? has the type Any :
func foo(map: [String: Any]) which forces me to downcast

Objective-C doesn't support nullable types in their generics and when you use them they become Any.

Need to use some wrapper around the SomeDataClass to hide the nulls.

Oh I see, thanks!
