I leave the WYSIWYG for the designer - it quickly falls apart for actually programming complex UIs. My job is to translate PSDs into working UI. There's a good reason we abandoned WYSIWYG for web design years ago and a modern mobile app is no less dynamic.
I can change the underlying grid size, padding and item spacing for every screen in my entire app in one line. Have fun doing that in iOS.
