I think it is too soon to tackle this issue.
I think there is room for making adapters for a lightweight GUI toolkit for embedded applications. For example, a Swift adapter for EFL <https://www.enlightenment.org/about-efl> (of Enlightenment) or something like that. But when we talk about Android, we are usually talking about a real Android app that can be a good citizen in Google ecosystem. I don’t think this is feasible right now.
Current Android GUI services is too intertwined with its proprietary runtime and VM and Google is continuing to tie them harder and harder to its Google services API. Unless Google starts treating non-Dalvik-based languages as first class citizens in Android development world, there is no point in trying to make Swift usable as a GUI development language for Android. It is not going to work.
Just my opinion.
