47. Swift to Kotlin Swift͔ΒkotlinͷίʔυΛ࡞ΔOSS https://github.com/angelolloqui/SwiftKotlin In fact, I explored an actual example using MVVM+Rx, where I got between a 50% and 90% of code similarity depending on the layer (non UIKit dependent is much more reusable than UIKit dependent classes of course). It took me around 30% the time to convert the Android version from the iOS version and I did not have SwiftKotlin then ;)
