Learn Quaternions vs HIGLab

Learning quaternions doesn't have to be hard! This app is a visual way to learn how quaternions work that makes it fun and interactive. Move the sliders to see the angle and axis of rotation change. Drag across screen to move around the scene. Made with RealityKit.

Designing for the Apple ecosystem requires more than just knowing the rules; it requires understanding how native components feel, react, and scale. Welcome to the ultimate interactive companion for Apple’s Human Interface Guidelines (HIG). Whether you are a seasoned iOS developer, a UI/UX designer, or just starting your Swift journey, this app bridges the gap between theory and execution. Static documentation can only teach you so much. We transformed the HIG into a living, breathing playground. Tweak parameters, test dynamic typography, experiment with dark mode, and see how native components behave in real-time. Build your intuition for Apple's design language by getting hands-on with the very building blocks of iOS, iPadOS, and visionOS. Core Features • Interactive Playgrounds: Manipulate native sliders, toggles, buttons, and pickers to see exactly how they respond to user input and accessibility settings. • HIG Cheatsheets: Quickly access beautifully summarized rules, best practices, and "do's and don'ts" directly from Apple's official documentation. • Typography & Color Labs: Test system colors, semantic materials, and dynamic type scales to ensure your app looks perfect in both Light and Dark modes. • Component Gallery: Browse a comprehensive library of native UI elements, complete with code snippets to instantly implement them in your Xcode projects. • Accessibility Preview: See your designs through the lens of your users by toggling VoiceOver outlines, increased contrast, and larger text sizes on the fly.
