Apple HIG: Technologies

Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.

Key Principles

General

Apple technologies extend app capabilities through system integration. Each technology has established user-facing patterns; deviating creates confusion and erodes trust.

Privacy and user control are paramount. Especially for health, payment, and identity technologies. Request only needed data, explain why, respect choices.

Siri and Voice

Natural, predictable, recoverable. Clear conversational intent phrases that complete quickly and confirm results. Support App Shortcuts for proactive suggestions. Handle errors with clear fallbacks.

Payments and Commerce

Transparent and frictionless. Standard Apple Pay button styles. Never ask for card details when Apple Pay is available. Clearly describe what the user is buying, the price, and whether it's one-time or subscription.

Health and Fitness

Health data is deeply personal. Explain the health benefit before requesting access. CareKit tasks should be encouraging. ResearchKit consent flows must be thorough, readable, and respect autonomy.

Smart Home

Simple and reliable. Immediate response when controlling devices. Clear device state. Graceful handling of connectivity issues.

Augmented Reality

Genuine value, not gimmicks. Use AR when spatial context improves understanding. Guide setup (surface, lighting, space). Provide clear exit back to standard interaction.

Machine Learning and Generative AI

Enhance without surprising. Smart suggestions, image recognition, text prediction. Clearly attribute AI-generated content. Controls to edit, regenerate, or dismiss. Let users correct mistakes.

Identity and Authentication

Sign in with Apple as top option. Standard button styles. Respect email hiding preference. ID Verifier: guided flows, don't store sensitive data beyond what verification requires.

Cloud and Data

Invisible and reliable sync. Data appears on all devices without manual intervention. Handle conflicts gracefully. Never lose data.

Shared Experiences

Real-time participation. SharePlay: support multiple participants, show presence, handle latency. AirPlay: appropriate Now Playing metadata.

Automotive

Driver safety first. Minimize interaction complexity, large touch targets, no distracting content. Only permitted app types: audio, messaging, EV charging, navigation, parking, quick food ordering.

Accessibility

Baseline requirement. Every element has a meaningful VoiceOver label, trait, and action. Support Dynamic Type, Switch Control, and other assistive technologies. Test entirely with VoiceOver enabled.

Output Format

Implementation checklist -- step-by-step requirements per Apple's guidelines.
Required vs optional features for approval.

User-facing flow from permission prompt through task completion.
Testing guidance -- key scenarios including edge cases.

Questions to Ask

Which Apple technology?
Core use case?
Which platforms?
API requirements and entitlements reviewed?
What data or permissions needed?
