I think that the BeeWare folks plans to help support this in cibuildwheel, I was told later this year at PyCon.

Confirming that yes, we (the BeeWare folks) are working on this. I've got an initial WIP branch with iOS support, which is sufficient to get a simple project building, but still needs a lot of work. #2062 is the first piece of that work to be upstreamed.

Hi, will Android (PEP738) be supported?

@Jzhenli Yes - it's on our (BeeWare's) todo list. We're trying to get iOS support added first, rather than trying to add 2 platforms at once.

(EDIT - I'm a contributor to cibuildwheel, not a maintainer, so any support is of course subject to the PR being accepted by the cibuildwheel maintainers)

iOS merged. Now just Android left. ;)

We're working on it!
