Maxwell is like Material Design or Bootstrap for the SwiftUI revolution. Software Makers waste more than half of development time due to design hand-off iteration. Recreating apps from images and mockups is not accurate, hard to refactor, and scale. Designers can Code!⁠ —LUX is a compositional, natural language extension that makes it easy to learn SwiftUI by removing the need to deal with numbers, allowing to define visually rich, deep, and flexible interfaces with just 5 keywords: lux, trait, tweak, style, feature. Developers can Design! ⁠—All this power is unleashed through Maxwell, a first of its kind "meta app" enabled to change skin and layout in realtime. This is the perfect demo for the framework and also the best learning resource as the source code is accessible within the app. Maxwell LUX is the first Universal Design System for iOS and macOS.
