What's the rationale behind having such a tiny font size for the title and text labels?

I don't know about you but that's basically the only thing that your calendar add event example differs in when compared to the original screen.

Why isn't UIFontTextStyleBody the default value in XLFormDescriptorCell -update methods on your cells instead of UIFontTextStyleHeadline? Should drop the "Bold" trait as well in order to reproduce iOS defaults.

Am I missing something?
