Not in Oakland or a woman (but a swift developer, 1 out of 3 ;)) but if she is learning to code, and wants to chat with other people, won't it be ok for her to just join regular swift groups? (I know there are a few around that general area).
Again, man here, so don't want you to take this the wrong way (might be because my wife actually gets along better with men then women) but won't limiting the meetup to a gender limit the talk and experience options you might get if you host this meetup?
