Hi there! I've been working with Kotlin for a couple of weeks now (for Android Development). I'm a big fan! Don't want to go back to Java anymore simple smile
I'm also a iOS developer, Kotlin brings all the Swift goodness (and more) to Android with fantastic IDE support 👍
Getting started with Kotlin was so easy and interop is great! That enabled me to use Kotlin in a large existing project without breaking a sweat! 👍
