SwiftUI and AppKit animation best practices for Apple platforms. Use when writing, reviewing, or implementing animations in SwiftUI (iOS 17+) or AppKit. Triggers on tasks involving transitions, easing, springs, gestures, matched geometry, phase animators, or motion.
Use when migrating from Realm to SwiftData - comprehensive migration guide covering pattern equivalents, threading model conversion, schema migration strategies, CloudKit sync transition, and real-world scenarios
Expert-level Swift development for iOS, macOS with SwiftUI, Combine, and modern Swift 5.9+
Use when working with ANY data persistence, database, axiom-storage, CloudKit, migration, or serialization. Covers SwiftData, Core Data, GRDB, SQLite, CloudKit sync, file storage, Codable, migrations.
Use when debugging navigation not responding, unexpected pops, deep links showing wrong screen, state lost on tab switch or background, crashes in navigationDestination, or any SwiftUI navigation failure - systematic diagnostics with production crisis defense
iOS crash-hunter skill that finds and fixes gnarly concurrency, memory, and I/O bugs using TDD. Every rule shows dangerous code, a failing test that proves the crash, and the fix that makes it pass. Complements ios-testing, swift-optimise, and other ios-*/swift-* skills. Triggers on tasks involving data races, retain cycles, deadlocks, async/await pitfalls, file corruption, thread safety, or crash debugging in Swift/iOS apps.
Reviews Swift code for concurrency correctness, modern API usage, and common async/await pitfalls. Use when reading, writing, or reviewing Swift concurrency code.
Build, refactor, or review macOS menubar apps that use Tuist and SwiftUI. Use when creating or maintaining LSUIElement menubar utilities, defining Tuist targets/manifests, implementing model-client-store-view architecture, adding script-based launch flows, or validating reliable local build/run behavior without Xcode-first workflows.
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.
Comprehensive iOS development guidance including Swift best practices, SwiftUI patterns, UI/UX review against HIG, and app planning. Use for iOS code review, best practices, accessibility audits, or planning new iOS apps.
Use when optimizing Swift code performance, reducing memory usage, improving runtime efficiency, dealing with COW, ARC overhead, generics specialization, or collection optimization
iOS/macOS app localization management for Tuist-based projects with .strings files. Use when: (1) Adding new translation keys to modules, (2) Validating .strings files for missing/duplicate keys, (3) Syncing translations across languages, (4) AI-powered translation from English to other locales, (5) Checking placeholder consistency (%@, %d), (6) Generating localization reports, (7) Updating Swift code to use localized strings instead of hardcoded text.
