If your code looks like it's Kotlin & quacks like it's Kotlin, then it probably is Swift.

" summary

Built a tiny dog‑breed guessing game with 10 rounds and local scoring, implemented natively on both platforms while swapping roles so iOS dev writes Kotlin and Android dev writes Swift. Architecture uses MVVM, Retrofit/Alamofire for networking, SharedPreferences/UserDefaults for storage, and shares around 80% of repository code and ~50% of ViewModel logic. Kotlin coroutines, LiveData and Koin simplify Android async and DI; Swift uses structs, protocols and enums (sealed classes emulate payload enums). The experiment succeeds and reveals concrete syntax and platform tradeoffs.
