Verify Xcode 27, Command Line Tools, Apple SDKs, simulators, devices, XcodeBuildMCP, Xcode native agent access, and Icon Composer 2 before Apple platform work. Use when setup, DEVELOPER_DIR, SDK, runtime, simulator, device, MCP, or toolchain drift could affect macOS, iOS, iPadOS, watchOS, tvOS, or visionOS builds.

Design and implement App Intents, App Entities, App Shortcuts, Spotlight, Siri, widgets, controls, and app-routing handoffs for Apple apps. Use when exposing app actions or content to system surfaces across iOS, iPadOS, macOS, watchOS, widgets, Shortcuts, Siri, or Spotlight.

Build, run, test, launch, log, screenshot, and debug Apple apps with Xcode 27, XcodeBuildMCP, xcodebuild, SwiftPM, simulators, devices, and macOS paths. Use when launching an app, proving a build, inspecting runtime behavior, wiring a Codex Run button, or diagnosing Apple build/test/runtime failures.

Design and implement Apple Foundation Models features with availability checks, guided generation, tool calling, prompt/transcript hygiene, privacy boundaries, and Instruments proof. Use when adding on-device Apple intelligence, local model summarization, extraction, classification, or tool-backed reasoning to an Apple app.

Localize and accessibility-test Apple apps with string catalogs, assets, previews, locale/layout proof, Dynamic Type, VoiceOver, contrast, motion, keyboard, switch/control access, and Xcode 27 localization workflows. Use when preparing Apple app UI for multiple languages, accessible interaction, App Store quality, or regression-proof visual behavior.

Diagnose Apple app launch/runtime performance, SwiftUI invalidation, hangs, Instruments traces, Top Functions, ETTrace profiles, dSYMs, memgraphs, leaks, retain cycles, and Foundation Models traces. Use when an Apple app is slow, janky, memory-heavy, leaking, hanging, or needs before/after profiling evidence.

Mirror iOS Simulator into the Codex in-app browser and render SwiftUI package previews with hot reload. Use when the user needs browser-visible Simulator proof, interactive iOS app viewing, SwiftUI preview iteration outside Xcode Canvas, or screenshot evidence from the Codex browser.

Diagnose Apple signing, entitlements, capabilities, provisioning, device install, sandbox, hardened runtime, Gatekeeper, notarization, TestFlight, and App Store validation issues. Use when builds or launches fail because of trust, identity, entitlement, provisioning, packaging, or distribution state.

Build and refactor Apple SwiftUI, AppKit interop, Liquid Glass, navigation, windowing, settings, tabs, toolbars, Observation, previews, and platform-native UI structure. Use when shaping Apple app presentation surfaces across macOS, iOS, iPadOS, watchOS, tvOS, or visionOS.
