2019/1/31. Kotlin2Swift
I am developing the app Swift2Kotlin, which can convert Swift code to Kotlin code. And I also think about another app which can convert Kotlin code to Swift code.
Swift is very good language for beginners to develop iOS apps.
And Kotlin is also good language for beginners to develop Android apps.
So the first language for programming beginners will be Swift or Kotlin.
So there may be demands for Kotlin2Swift.
