# iOS Platform Capabilities

<!-- dual-compat-start -->
## Use When

- Implementing or reviewing iOS capabilities that require Apple frameworks, entitlements, permissions, device hardware, background delivery, or native export.
- The task references LocalAuthentication, CoreBluetooth, APNs, notification extensions, URLSession, offline queues, certificate pinning, or `UIGraphicsPDFRenderer`.
- A retired capability skill is referenced by name.

## Do Not Use When

- The work is general iOS architecture or UI without a platform framework capability.
- The work is StoreKit monetization; use `ios-monetization`.
- The work is security/RBAC governance rather than capability implementation; use `ios-security-and-rbac`.

## Required Inputs

- Capability scope, target iOS versions, entitlements, permission copy, backend/API contract, offline requirements, privacy disclosures, and relevant device constraints.

## Workflow

1. Load `ios-development` for baseline Swift and app-structure rules.
2. Load `ios-security-and-rbac` when the capability touches secrets, identity, device trust, authorization, or tenant data.
3. Pick the reference for the requested capability and follow its implementation workflow.
4. Verify simulator/device limitations, entitlement setup, fallback behaviour, and user-facing permission states.

## Quality Standards

- Capabilities must handle permission denied, unavailable hardware, offline operation where relevant, and background lifecycle constraints.
- Native framework use must be testable, privacy-compliant, and documented in release notes or app-review evidence when required.

## Anti-Patterns

- Implementing hardware or notification features without real-device verification.
- Hiding entitlement, permission, or App Review requirements inside code comments only.
- Building PDF/report/networking features without retry, failure, and export-state handling.

## Outputs

- Capability implementation guidance, framework integration checklist, entitlement/privacy notes, test plan, or review findings.
