Separation of concerns: Refactoring view controllers live
summary
Live refactoring of a Swift app converts a 73-line view controller into 32 lines by extracting concrete pieces: a Bundle extension for JSON decoding, an attributed-title computed property moved into the Project model, a reusable ProjectDataSource class, a DetailView UIView subclass with a closure-based readAction, a NavigationDelegate for WKWebView plus a WKWebView URL-loading extension, and a MainCoordinator that boots the app (removes storyboard) and calls MainCoordinator.start(). All pieces compile and run live, demonstrating smaller, testable modules.
