This is a really interesting development. I've been poking around with making a cross-platform library lately, and had settled on Go because it does such a great job of building for iOS and Android simply (though the go bind tool), but the implementation feels a little messy because the nature of Go (e.g., no classes, property accessors, etc) doesn't translate easily to Objective-C or Java. So Kotlin might be a really interesting alternative here.

How about Flutter with Dart? It uses AOT so plays well with IOs. But granted, their approaches are very different as Flutter renders most things by itself.

The project I'm working on doesn't use any UI (that's still native), so I'd disregarded Flutter - but perhaps that's not fair. Looking at it, it seems to have straightforward ways to use native functionality, but I'm not 100% sure how I might go about exposing Dart classes/methods/etc to existing native code. Worth looking into, though - thanks!
