Kotlin for Swift Developers
summary
Converts a small iOS to‑do app (UITableView, JSON API) into a working Android app (RecyclerView) by copy‑pasting and adapting Swift to Kotlin code, demonstrating concrete differences: val vs var, nullability and early returns, Swift value-type structs vs Kotlin reference data classes, smart casting and pattern matching, and using sealed classes instead of Swift enums. Networking uses Retrofit and shows handling nullable response bodies. The converted app runs and the demo highlights exact code changes and pitfalls to watch for.
