This is basically perfect - and I appreciate your patience, I'm just getting caught up over here after summer travel. I made a nitpick/tiny suggestion that I should be able to apply myself, then we can get this merged

I just tacked on a commit with diff from yarn lint:ios:fix run on local pull of PR, should go green now I think 🤞
