Watchos Design Guidelines

This is Apple's HIG for Watch distilled into actionable rules you can reference while building watchOS apps. It covers the critical stuff: glanceable design principles (2-second comprehension targets), Digital Crown integration with haptic feedback, shallow navigation patterns, and complication design with WidgetKit timeline providers. Each section includes specific rules with IDs like W-GL-01, code examples showing correct and incorrect implementations, and screen dimension tables for current Watch models. Useful when you're designing complications, workout features, or any wrist-based UI where you need to remember that people interact in 5-second bursts, not sustained sessions. The anti-patterns section alone will save you from common mistakes like ignoring the Crown or building deep navigation hierarchies.
