If you're building an iOS, macOS, or visionOS app and need to pick between tab bars, sidebars, split views, or column navigation, this skill walks you through Apple's HIG recommendations for layout and navigation components. It covers the practical stuff like when to collapse a three-column layout on iPhone, how to handle iPad multitasking at different split ratios, and where ornaments belong on visionOS windows. The reference index is thorough, linking to specific guidance on everything from outline views to scroll view paging. Most useful when you're architecting navigation or debugging why your layout breaks across size classes.
