HIG Lens — iOS design review of pasted SwiftUI code

Paste Swift/SwiftUI code and get an independent iOS design review written against Apple's Human Interface Guidelines as they stood in February 2026: a sound/refactor/rework verdict, a health check across five design areas (layout & adaptivity, typography & Dynamic Type, color & dark mode, navigation & structure, accessibility), concrete findings with corrected SwiftUI, a twelve-point checklist, coverage reconciliation against the free SwiftScan prescan, and a full refined rewrite shown as a line diff against your own paste. The prescan runs free in your browser. Guidance only: the guidelines change with each OS release and the current HIG governs. Not affiliated with, authorised by or endorsed by Apple Inc., and no prediction of App Review outcomes. Derived from @wshobson/mobile-ios-design (MIT).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
