Review iOS UI Against Apple HIG

Purpose

Use this skill to review an iOS interface against Apple Human Interface Guidelines, iOS conventions, and observable product behavior.

Default to review-only. Do not edit files unless the user explicitly asks for fixes.

Define the review surface: identify the app screens, screenshots, SwiftUI/UIKit files, simulator state, and target devices or size classes involved.
Gather evidence from the actual artifact. Prefer screenshots, simulator runs, UI previews, or concrete SwiftUI/UIKit code over generic assumptions.
Read references/apple-hig-review.md before making guideline claims, then read the page-specific reference files it routes to. If the user asks for the current or exact Apple rule, verify the linked Apple page live.
Review by category: platform fit, layout, navigation, controls and input, typography, color and materials, accessibility, feedback states, destructive actions, and iPad/adaptive behavior when relevant.
Rank findings by user impact and confidence. Prioritize issues that affect comprehension, task completion, accessibility, safety, or platform expectation.
Report findings with evidence and a concrete recommendation. Avoid broad redesign advice unless it follows directly from an observed issue.
