HIGLab

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.
