Kotlin Native doesn't exist beyond pre-alpha software at this point, so the the question is a bit premature. In 3-5 years Kotlin might be where Swift is now, but there's nothing guaranteed, just coming up with a GC solution alone is a gigantic engineering effort -- Kotlin, like Scala, Clojure, etc. all benefit from world class GCs, just by being hosted on the JVM. With LLVM you essentially start from scratch, same for porting Java libraries, there's a ton of work involved. tl;dr; for now it's separate languages for iOS and Android unless you cut some corners with React Native to avoid writing the same app twice.
