description

Use this skill to gate iOS SwiftUI design and UX with a pass/fail adversarial review — a single blind reviewer subagent judges screens, diffs, or features against 56 decidable HIG-derived rules, working backwards from mandatory rendered evidence, simulator screenshots (light, dark, accessibility text size) and interaction recordings tiled into filmstrips. Covers navigation/IA (tab bars, five tabs max, system Back), modality and flow grammar (sheets, alerts, unsaved-content protection), layout (44pt targets, safe areas, Dynamic Type), color and contrast, typography floors, Liquid Glass, feedback states (empty, loading, error, launch), motion — filmstrip-primary except the spring-curve and Reduce Motion checks, so code alone never prescribes an unseen animation, and gratuitous decoration fails — plus haptics and craft. Fixes must be the minimal change, removal preferred over addition. Trigger before merging user-facing SwiftUI work. Verdicts only, never fixes; targets without a SwiftUI UI surface abort.

Adversarial iOS Design Gate

An iOS design-and-UX review gate — pass/fail: a single blind reviewer subagent judges the work against this gate's rules with an adversarial mandate, and the work passes only when every rule is PASS or N/A. This skill renders verdicts; it never fixes the work.

The gate judges rendered user interface, not source text. Capturing evidence — simulator screenshots and interaction recordings tiled into filmstrips — is a mandatory protocol step, and the reviewer works backwards from the pixels: observe the captures, suspect violations, then open code only to locate them. Code-only review is the gate's recorded failure mode: it turns the gate into a linter that prescribes animations it has never seen.

The rules are the decidable subset of what an Apple design review would flag — every rule names the evidence that decides it, drawn from the Human Interface Guidelines, WWDC design sessions, and Apple's own measured app conventions. The gate judges the failure modes agents and experienced-but-not-expert developers actually ship: hamburger drawers where tab bars belong, pushed forms that lose drafts on a swipe, alerts that say "Yes"/"No", blank empty states, whole-screen spinners, teleporting state changes, glass painted on content, and text that clips at accessibility sizes.
