Model View Controller

" summary

Argues that classic MVC on iOS breeds huge view controllers and shows a concrete refactor: a Swift UIKit app with a 600-line view controller is split into a refactor into coordinator pattern, a slimmed view, and a plain model. Live demo shows the app still running after the changes, XCTest targets added to cover logic, and build-time warnings drop. Code snippets and before/after file sizes make the benefit visible rather than theoretical.
