I had added Skip to my Swift resource list a while back, and consider it to be a conceptually brilliant solution to bridge the gap between iOS and Android development with a single codebase while trying to keep things as native as possible at either end.
Still, given how it converts things into Kotlin and the fact that it is free for Open-Source apps (and one indie closed-source one), it might be one of the few cross-platform solutions genuninely worth looking into.
I’d just be extremely wary of any proprietary bits when evaluating it more in depth…
