A11y-oop Adding new Accessibility Features to not-so-new Apps
summary
Medium iOS (in the App Store ~4 years) gains app-wide night mode and dynamic type by adding small services: display mode service (stores choice in NSUserDefaults and notifies subscribers), content size service (observes UIContentSizeCategoryDidChange), and background/icon/text color model providers. View models consume these injected services (initialized in AppDelegate) to produce attributed strings and colors; string attribute service is retired and replaced by dynamic typography. Projects hit parity with Android, apply to all surfaces except the story page, and ship quickly thanks to specs and a mobile squad.
