Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags.
Choose and implement iOS architecture patterns (MVVM, TCA, Clean Architecture) based on feature complexity. Use when designing architecture for new features or refactoring existing code.
Break down features into implementable tasks and choose architecture approach. Use when starting a new feature or receiving requirements that need technical decomposition.
End-to-end GitHub issue fix workflow using gh, local code changes, builds/tests, and git push. Use when asked to take an issue number, inspect the issue via gh, implement a fix, run XcodeBuildMCP builds/tests, commit with a closing message, and push.
Use XcodeBuildMCP to build, run, launch, and debug the current iOS project on a booted simulator. Trigger when asked to run an iOS app, interact with the simulator UI, inspect on-screen state, capture logs/console output, or diagnose runtime behavior using XcodeBuildMCP tools.
Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.
Use when building UIKit interfaces without storyboards, setting up Auto Layout constraints with anchors, creating reusable UI components, or encountering layout constraint errors and ambiguous layout warnings.
Use when implementing Realm database in iOS apps, encountering thread-safety errors, async/await crashes, performance issues with sync/writes, or integrating with Codable APIs.
Use when implementing JSON encoding/decoding with Codable, handling API responses, encountering decoding errors, managing date formats, mapping snakecase to camelCase, or dealing with nested/inconsistent JSON structures.
Expert guidance on Swift Concurrency best practices, patterns, and implementation. Use when developers mention: (1) Swift Concurrency, async/await, actors, or tasks, (2) "use Swift Concurrency" or "modern concurrency patterns", (3) migrating to Swift 6, (4) data races or thread safety issues, (5) refactoring closures…
Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file.
Use when implementing data persistence in iOS apps with SwiftData or CoreData, encountering migration errors, performance issues with fetches, or choosing between persistence frameworks.
Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is…
Best practices and example-driven guidance for building SwiftUI views and components. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens, or needing component-specific patterns and examples.
Refactor and review SwiftUI view files for consistent structure, dependency injection, and Observation usage. Use when asked to clean up a SwiftUI view’s layout/ordering, handle view models safely (non-optional when possible), or standardize how dependencies and @Observable state are initialized and passed.
Implement VIP (View-Interactor-Presenter) Clean Architecture for iOS apps requiring maximum testability, unidirectional data flow, and protocol-based boundaries. Use when refactoring complex features or building enterprise apps with strict separation of concerns.
Use when architecting complex iOS apps with multiple features, long-term maintenance requirements, or team scalability needs. Use when refactoring Massive View Controllers or implementing testable architecture. Do NOT use for simple single-screen apps, rapid prototypes, or small utility tools.
