description	Non-functional requirements checklist for iOS features

Purpose

Ensure iOS stories address NFRs. Complement security policies and stack conventions.

iOS-specific concerns (always consider)

1. App Store readiness — permission purpose strings, entitlement/capability changes documented
2. Battery — no high-frequency polling; efficient image handling
3. Offline correctness — local persistence as source of truth; migration plan for schema changes; bounded storage growth
4. Accessibility — accessible labels on controls; dynamic type doesn't break layouts; adequate tap targets
5. Performance — no main-thread blocking; smooth scrolling; network calls don't block UI

For standard concerns, output format, and flexibility rules, see /shared-nfr.

iOS-specific standard concern additions

• Reliability: failure states handled gracefully
• Security: appropriate storage for sensitive values (keychain when needed)
• Observability: critical transitions logged with stable identifiers
