Scaling beyond Storyboards
summary
A runtime UI system called layout XML templates builds iOS screens with UIKit names, a pure-Swift expressions library for math/conditionals, and hot-reload in the simulator so edits apply without recompiling. It positions by frames (not Auto Layout) for faster performance, supports state binding and strong-typed view models, handles recyclable table/collection cells with dynamic heights, loads localized or remote XML over the wire, and reports recoverable runtime template errors instead of crashing.
