If you're building interfaces that need to meet WCAG 2.2 Level AA, this gives you the technical implementation details across web, iOS, and Android. It maps semantic HTML and ARIA to SwiftUI accessibility traits and Compose semantics, so you're not constantly context-switching between platform docs. The cross-platform table alone is worth having on hand. It covers the newer 2.2 criteria like 24px minimum target sizes and focus appearance, plus practical stuff like focus trapping in modals and when to use aria-live versus accessibilityLiveRegion. Best for auditing existing code or spec'ing out components when you need to be confident about what actually ships to assistive tech.
