Is there way to build framework for swift and not for ObjectiveC?

frameworks produced by K/N could be consumed by both Swift and Objective-C, and it containes Swift-specific annotations

With the next major Swift release, they are taking steps to solidify their ABI. Once Swift has a decided ABI, will Kotlin compile directly to Swift?

if there will be enough motivation to switch to Swift framework - we could, but generally allowing to use framework from both Objective-c and Swift looks like an advantage

Generics could be one motivation

Kotlin/Java generics are more like ObjC generics. It would be better to have Apple increase the availability of them throughout ObjC rather than limiting them to collection types.

Oh, let's ask them to do that 😁

lol, they definitely won't

It’s already there just not documented publicly and not very user friendly.
