Swift and Kotlin are the main languages used for iOS and Android apps. Chances are very high that this will remain true for years. Swiftlin allows converting your Swift code to Kotlin in just one click, aiming to save precious time for mobile developers.
I hired Swiftlin to do a conversion of my app from iOS to Android. The experience was smooth and professional, especially given no prior experience with them. While my app was not especially complex, they were able to port it quickly and iterate through a few tweaks to make me a happy a customer. I would use them again.
