I'm not the right person to comment on the React Native part. (There's definitely quite a bunch of React Native in the app on top of the Kotlin) Other people are also working on Obj-J/Swift, but from my superficial knowledge I think it's a much harder migration to do. I really think the Kotlin team did amazing language and tool design which makes Java to Kotlin migration easier than almost any other language migration I could think off. Kudos to them.
