What problem does it solve? Ensuring a macOS app follows the macOS 26 (Tahoe) Human Interface Guidelines, Liquid Glass design language, and accessibility standards requires deep platform expertise that is easy to miss during development. ## Core Features & Use Cases - Structured UI Audits: Systematically reviews SwiftUI and AppKit interfaces against five reference modules covering Liquid Glass design, macOS Tahoe HIG, SwiftUI patterns, modern AppKit, and accessibility. - Prioritized Feedback: Categorizes findings as Critical, Important, or Nice-to-have, each with the violated guideline, user impact, concrete code fix, and Apple documentation links. - Use Case: Before shipping a macOS 26 note-taking app, submit your SwiftUI views or screenshots to verify VoiceOver support, transparent menu bar integration, toolbar conventions, and Dynamic Type scaling. ## Quick Start Review my macOS app's SwiftUI views for macOS Tahoe HIG compliance and accessibility issues.
