Upgrades React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json dependencies, migrating native iOS and Android configuration, resolving CocoaPods and Gradle changes, and handling breaking API updates. Use when upgrading React Native, bumping RN version, updating from RN 0.x to 0.y, or migrating Expo SDK alongside a React Native upgrade.
Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.
Use when adding Auth0 authentication to .NET iOS applications - integrates Auth0.OidcClient.iOS NuGet package for native login, logout, token management, and user profile via ASWebAuthenticationSession with PKCE. Trigger on .NET iOS auth, .NET 8 iOS auth, .NET 9 iOS auth, add login to .NET iOS, Auth0 iOS C#, Xamarin iOS auth, Auth0 OIDC iOS, ASWebAuthenticationSession login .NET, native iOS C# authentication
Create model classes with `fromJson` and `toJson` methods using `dart:convert`. Use when manually mapping JSON keys to class properties for simple data structures.
Implement a component-level test using `WidgetTester` to verify UI rendering and user interactions (tapping, scrolling, entering text). Use when validating that a specific widget displays correct data and responds to events as expected.
Remove the DebugBridge SPM package and all #if DEBUG wiring from an iOS app. (gstack)
GitHub Actions workflow patterns for React Native iOS simulator and Android emulator cloud builds with downloadable artifacts. Use when setting up CI build pipelines or downloading GitHub Actions artifacts via gh CLI and GitHub API.
Adds interactive widget previews to the project using the previews.dart system. Use when creating new UI components or updating existing screens to ensure consistent design and interactive testing.
Migrates Auth0.swift v2.x integrations to v3.x. Pass a target v3 tag as an argument (e.g. auth0-swift-major-migration 3.0.0-beta.2) to pin a specific version, or omit it to auto-resolve the latest v3 release. Detects the current version, fetches the new SDK's actual source to confirm signatures, audits which Auth0 APIs the project actually uses, and applies only the breaking changes that affect real call sites — nothing else. Builds until green, then summarises what changed.
When the user wants to audit or optimize an App Store or Google Play listing. Also use when the user mentions 'ASO audit,' 'app store optimization,' 'optimize my app listing,' 'improve app visibility,' 'app store ranking,' 'audit my listing,' 'why aren't people downloading my app,' 'improve my app conversion,' 'keyword optimization for app,' or 'compare my app to competitors.' Use when the user shares an App Store or Google Play URL and wants to improve it.
Use when adding Auth0 authentication to an iOS, macOS, tvOS, watchOS, or visionOS application — integrates the Auth0.swift SDK for native Apple platform authentication using Web Auth, CredentialsManager, and biometric protection.
