The code you don’t have to write
summary
Implements navigation where view controllers declare input requiring and output producing types and get an input property and produceOutput function via extensions, then Swift’s type checker and a dynamic lookup match outputs to destinations so most transitions need no custom code. Storyboards convert segues into transitions with a build step, UIViewController.show picks the presentation style, and a small open‑source library called story flow bundles the enums, flow variable on output controllers, and segue→transition wiring so flows compile and route automatically.
