Has anybody tried converting a KMM project that was created with Android studio to one that would work with App code? I saw this article and liked the ability to refactor swift code when the kotlin code is changed and was just curious what that experience was like if I were to do that to an existing project of mine.

Not yet, but I'm strongly considering it once my M1 comes in the mail. I'd like to hear others experiences as well...

Yes I tried that for some time, without any success, to be honest. I had problems of different kinds, which I couldn’t solve. I am working on a M1 Mac, maybe that’s even part of the problem, I doubt it though. I was able to get it running with a fresh project, but unfortunately not with existing projects, of which I tried multiple.
