As an iOS developer who's looking to port to Android, this makes it easier to manually port my Swift code to Kotlin. But I wish there were automated tools. If two languages are this similar conceptually, such a tool should be easy to write, and handle the majority of cases.

I don't mind if this tool prohibits a few features (pattern-matching in Swift, say), even if it's considered idiomatic, because not having to maintain another codebase saves more than enough productivity to make it worth it.

Does such a tool exist?
