Build 3D scenes and visualizations using SceneKit. Use when creating 3D views with SCNView and SCNScene, building node hierarchies with SCNNode, applying materials and lighting, animating with SCNAction, simulating physics with SCNPhysicsBody, loading 3D models (.usdz, .scn), adding particle effects, or embedding SceneKit in SwiftUI with SceneView. Note: SceneKit was deprecated at WWDC 2025 and is in maintenance mode; RealityKit is recommended for new projects.
API reference: Swift Testing framework. @Test, @Suite, #expect, #require, traits, parameterized tests, migrating from XCTest.
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 insufficient.
Swift and SwiftUI refactoring patterns aligned with the iOS 26 / Swift 6.2 clinic modular MVVM-C architecture (Airbnb + OLX SPM layout). Enforces @Observable ViewModels/coordinators, App-target `DependencyContainer` + route shells, Domain repository/coordinator/error-routing protocols, and Data-owned I/O with stale-while-revalidate plus optimistic queued sync boundaries. Use when refactoring existing SwiftUI code into the clinic architecture.
SwiftData class inheritance patterns for hierarchical models with type-based querying, polymorphic relationships, and when to choose inheritance vs enums. Use when designing SwiftData model hierarchies.
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.
Reviews Swift code for concurrency safety, error handling, memory management, and common mistakes. Use when reviewing .swift files for async/await patterns, actor isolation, Sendable conformance, or general Swift best practices.
Design and implement visionOS SwiftUI scenes that integrate RealityKit content. Use when building spatial UI with RealityView, Model3D, attachments, volumetric windows, ImmersiveSpace, or spatial gestures, or when choosing SwiftUI vs RealityKit APIs for 3D presentation.
Expert Swift decisions Claude doesn't instinctively make: struct vs class trade-offs, @MainActor placement, async/await vs Combine selection, memory management pitfalls, and iOS-specific anti-patterns. Use when writing Swift code for iOS/tvOS apps, reviewing Swift architecture decisions, or debugging memory/concurrency issues. Trigger keywords: Swift, iOS, tvOS, actor, async, Sendable, retain cycle, memory leak, struct, class, protocol, generic
Test Swift applications - XCTest, Swift Testing, UI tests, mocking, TDD, CI/CD
Master Swift Package Manager - dependencies, creating libraries, publishing, local packages
Automatically applies accessibility best practices to Swift projects (SwiftUI and UIKit). Use when working on iOS/macOS projects that need VoiceOver support, Dynamic Type, WCAG compliance, or accessibility audits. Triggers on Swift accessibility tasks, a11y improvements, or when the user mentions accessibility, VoiceOver, or Dynamic Type.
