Swift 6.2 and SwiftUI performance optimization for iOS 26 clinic architecture codebases. Covers async/await concurrency patterns, Sendable/actor isolation, view/render performance, and animation performance while preserving modular MVVM-C boundaries across App, Feature, Domain, and Data layers. Use when profiling or optimizing Swift/SwiftUI behavior in clinic modules.
Build iOS UI screens in Swift (UIKit) from design specs, mockups, screenshots, or descriptions. Use this skill whenever the user wants to create, implement, or recreate any iOS interface, view controller, custom view, table/collection view, popup, alert, or any UIKit-based screen. Always use this skill when the user uploads a UI screenshot and asks to implement it in Swift, or mentions SnapKit, SwiftEntryKit, Kingfisher, SDWebImage, SwiftyJSON, or any iOS layout task. Covers full screens, individual components, navigation flows, and modal presentations.
Develop SwiftUI applications for iOS/macOS. Use when writing SwiftUI views, managing state, or building Apple platform UIs.
Use this skill when brainstorming, designing, or planning any Swift feature. This is the right skill whenever the user describes a feature they want to build, asks "how should I implement X", wants to think through a design, or starts with something like "I want to add..." or "let's plan...". Use it even if they don't explicitly say "brainstorm" — if there's a feature to figure out, start here before touching any code.
SOLID principles for Swift 6 and SwiftUI (iOS 26+). Files < 150 lines, protocols separated, @Observable, actors, Preview-driven development. Features Modular MANDATORY.
Implement, review, or improve accessibility in iOS/macOS apps with SwiftUI and UIKit. Use when adding VoiceOver support with accessibility labels, hints, values, and traits; when grouping or reordering accessibility elements; when managing focus with @AccessibilityFocusState; when supporting Dynamic Type with @ScaledMetric; when building custom rotors or accessibility actions; when auditing a11y compliance; or when adapting UI for assistive technologies and system accessibility preferences.
Use when integrating Foundation Models framework, implementing on-device AI with Apple Intelligence, building tool-calling AI features, working with guided generation schemas, converting models with Core ML and coremltools, or running open-source LLMs on Apple Silicon. Covers Foundation Models (LanguageModelSession, @Generable, @Guide, SystemLanguageModel, structured output, tool calling), Core ML (coremltools, model conversion, quantization, palettization, pruning, Neural Engine, MLTensor), MLX Swift (transformer inference, unified memory), and llama.cpp (GGUF, cross-platform LLM).
Apply modern Swift language patterns and idioms for non-concurrency, non-SwiftUI code. Covers if/switch expressions (Swift 5.9+), typed throws (Swift 6+), result builders, property wrappers, opaque and existential types (some vs any), guard patterns, Never type, Regex builders (Swift 5.7+), Codable best practices (CodingKeys, custom decoding, nested containers), modern collection APIs (count(where:), contains(where:), replacing()), FormatStyle (.formatted() on dates, numbers, measurements), and string interpolation patterns. Use when writing core Swift code involving generics, protocols, enums, closures, or modern language features.
Implement, review, or improve SwiftUI gesture handling. Use when adding tap, long press, drag, magnify, or rotate gestures, composing gestures with simultaneously/sequenced/exclusively, managing transient state with @GestureState, resolving parent/child gesture conflicts with highPriorityGesture or simultaneousGesture, building custom Gesture protocol conformances, or migrating from deprecated MagnificationGesture/RotationGesture to MagnifyGesture/RotateGesture.
Swift Combine framework for reactive programming, handling asynchronous events with publishers, subscribers, and operators.
This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference. Provides SF Symbols usage, rendering modes (monochrome, hierarchical, multicolor, palette), symbol effects, and variable values.
Writes and reviews Swift FormatStyle code, replacing legacy Formatter subclasses and C-style String(format:) with modern .formatted() APIs. Use when formatting numbers, dates, durations, measurements, lists, names, byte counts, or URLs.
