mobile-development
Build, test, sign, and ship mobile apps across iOS, Android, Flutter, and React Native — project scaffolding, builds and code signing, device and emulator testing, store submission (App Store and Play Store), app lifecycle and backgrounding, offline and sync, and mobile-specific testing. Use when the task involves creating, building, testing, or shipping a mobile app for iOS or Android, or reasoning about mobile behavior such as background execution, push notifications, offline storage, and data sync. Do not use for web frontend work (that is frontend-engineering), backend services and APIs (that is backend-engineering), or desktop and web platform targets outside the iOS and Android scope.

What this skill does
Mobile Development One skill for building mobile apps on iOS and Android — with per-framework depth for native (Swift/SwiftUI, Kotlin/Jetpack Compose) and cross-platform (Flutter, React Native) stacks. All four share one agent workflow — scaffold, build and sign, test on devices and emulators, and ship to stores — so they live in ONE family skill with per-framework references, following the frontend-engineering precedent. Load the shared workflow below, then pull the reference for the framework you are actually building. Framework Stack Reference (load on demand) ----------- ------- ---------------------------- iOS Swift, SwiftUI/UIKit, Xcode references/ios.md Android Kotlin, Jetpack Compose, Gradle references/android.md Flutter Dart, Flutter SDK references/flutter.md React Native TypeScript/JavaScript, React, Metro references/react-native.md When to use Load this skill when the task involves any part of the mobile lifecycle: Scaffold — creating a new mobile project for iOS, Android, Flutter, or React Native: choosing the framework, initializing the project, and setting up the platform toolchains. Build and sign — compiling a debug or release build, configuring code signing (certificates, provisioning profiles, keystores, app signing), or producing distributable artifacts (.ipa, APK, AAB). Test on devices and emulators — running and debugging on iOS simulators, Android emulators, or physical devices, including device provisioning, connectivity, and platform-specific runtime behavior. Ship to stores — submitting to the App Store (TestFlight, App Store Connect) or Google Play (internal/closed/open testing tracks, Play Console), and reasoning about store review readiness. Mobile-specific behavior — app lifecycle and backgrounding, offline storage and sync, push notifications, deep links, and mobile testing (unit, widget, UI, and device-farm testing). …
