An iOS interface design and development guide for SwiftUI, Apple's UI framework, targeting iOS 17 and newer on iPhone and iPad. It defines reusable design tokens and follows Apple's Human Interface Guidelines for layout, navigation, text sizing, icons, and modal screens.

Use it to build or improve SwiftUI screens, views, sheets, navigation stacks, tabs, and full-screen presentations while respecting safe areas, Dynamic Type, touch targets, and swipe-back navigation.

It prevents generated interfaces from relying on arbitrary spacing, generic layouts, unsuitable icons, or missing accessibility and navigation behavior. It also separates theme decisions from UI implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00102	$0.02246
Opus 5	$0.00051	$0.01123
Sonnet 5	$0.00020	$0.00449
Haiku 4.5	$0.00010	$0.00225

Security

Grade A, and why

ui-ios scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ui-ios — Slop-Free SwiftUI Skill

You are generating production-grade iOS UI in SwiftUI (iOS 17+) and Swift 5.9+. This skill exists because untouched LLMs produce AI slop: purple→pink LinearGradients, default centered VStack heros, three-card LazyVGrid features, magic numbers everywhere (.padding(13), .cornerRadius(7)), Inter on iOS, glassmorphism on every card, "Get Started" buttons, and the median of every SwiftUI tutorial scraped from GitHub. This skill replaces guesses with constraints.

The non-negotiable rule: NEVER use a buzzword in place of a token. Words like clean, modern, professional, sleek, premium are banned from your reasoning. Every aesthetic choice must trace back to a named anchor recipe in anchors.md and a value in Theme/Tokens.swift.

iOS adds a second non-negotiable: HIG mechanics are strict. 44pt minimum touch targets. SF Symbols only for system icons. Dynamic Type mandatory. Safe area respected. NavigationStack for navigation. .sheet / .fullScreenCover for modal presentation. Swipe-back gesture preserved. Brand has freedom over color, custom typography (with declared system fallback), accent, motion personality, and shape — not over the platform mechanics above.

Workflow (follow in order)

Step 0 — Project scan (decides bootstrap vs extend mode)

Before any other action, check for:

DESIGN_RULES.md                      # at repo root → if exists, you are in EXTEND mode
*/Theme/Tokens.swift                 # → if exists, you are in EXTEND mode
*/Theme/ThemeModifier.swift
.swiftlint.yml                       # check for custom slop rules

If DESIGN_RULES.md exists: read it. Read the existing Tokens.swift. Skip to Step 3 (Phase 2: UI). Use only existing tokens. NEVER add new colors/spacing/radii without asking.
If Tokens.swift exists but no DESIGN_RULES.md: read tokens, infer the closest matching anchor, ask the user to confirm the inferred anchor, then write DESIGN_RULES.md and proceed to Phase 2.
If neither exists: you are in bootstrap mode. Continue to Step 1.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ui-ios is a skill published in the GitHub repository rshzrh/ui-design-skills (4 stars, last pushed 5mo ago), licensed MIT. It adds 102 tokens to every session and 2,246 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
