A guide to applying Apple's Human Interface Guidelines to SwiftUI iOS apps. It covers navigation, touch interactions, accessibility, feedback, and visual design.

Use it when designing navigation, gestures, haptic feedback, loading and error states, accessibility support, or SwiftUI visual layouts.

It helps screens behave in familiar ways and makes app interactions clearer and more accessible to iPhone users.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

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	$0.00078	$0.01395
Opus 5	$0.00039	$0.00698
Sonnet 5	$0.00016	$0.00279
Haiku 4.5	$0.00008	$0.00139

Security

Grade A, and why

ios-hig 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 5d 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.

Apple iOS HIG Best Practices

Comprehensive guide for Apple Human Interface Guidelines compliance in iOS apps built with SwiftUI. Contains 34 rules across 6 categories covering navigation, interaction design, accessibility, user feedback, UX patterns, and visual design.

Clinic Architecture Contract (iOS 26 / Swift 6.2)

All guidance in this skill assumes the clinic modular MVVM-C architecture:

Feature modules import Domain + DesignSystem only (never Data, never sibling features)
App target is the convergence point and owns DependencyContainer, concrete coordinators, and Route Shell wiring
Domain stays pure Swift and defines models plus repository, *Coordinating, ErrorRouting, and AppError contracts
Data owns SwiftData/network/sync/retry/background I/O and implements Domain protocols
Read/write flow defaults to stale-while-revalidate reads and optimistic queued writes
ViewModels call repository protocols directly (no default use-case/interactor layer)

When to Apply

Reference these guidelines when:

Building navigation hierarchies with tab bars, NavigationStack, or split views
Designing touch interactions, gestures, and haptic feedback
Ensuring accessibility with VoiceOver, Dynamic Type, and color contrast
Implementing loading states, error handling, and empty states
Building onboarding flows, permission requests, and confirmation dialogs
Supporting dark mode, SF Symbols, and standard layout margins
Reviewing apps for HIG compliance

Rule Categories by Priority

Priority	Category	Impact	Prefix
1	Navigation	CRITICAL	`nav-`
2	Interaction Design	CRITICAL	`inter-`
3	Accessibility	CRITICAL	`acc-`
4	User Feedback	HIGH	`feed-`
5	UX Patterns	HIGH	`ux-`
6	Visual Design	HIGH	`vis-`

Quick Reference

1. Navigation (CRITICAL)

nav-tab-bar - Design tab bars for top-level navigation
nav-navigation-stack - Use NavigationStack for hierarchical navigation
nav-toolbar-placement - Place actions in toolbars using standard placements

What ships with it

Changes

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.
