Functional architecture guidance for Swift (immutability, pure functions, reducers, DI via functions).

Provides the complete Embedded Swift documentation for developing on microcontrollers, embedded systems, and baremetal applications.

Apple BackgroundTasks framework for iOS/iPadOS background processing. Use when scheduling background work, refreshing app content, running long processing tasks, implementing BGAppRefreshTask, BGProcessingTask, BGContinuedProcessingTask, or dealing with BGTaskScheduler setup, registration, submission, expiration handlers, and debugger testing commands.

Apple HealthKit framework for health and fitness data. Use for reading/writing health samples, workout data, authorization flows, observer queries, background delivery, clinical records, activity rings, and integrating with the Health app across iPhone, Apple Watch, iPad, and visionOS.

Official Swift DocC documentation markup and syntax reference

A dependency management library for Swift with controlled, testable dependencies

Type-driven domain modeling techniques for Swift using proper domain types, validation-carrying types, witness-based access control, and illegal-state elimination. Use when designing domain models, replacing primitive obsession, modeling workflows with enums/structs, adding compile-time guarantees, or discussing parse-dont-validate and making illegal states unrepresentable.

Apple Observation framework for Swift. Use when modeling observable state with the `@Observable` macro, tracking changes with `withObservationTracking`, integrating with SwiftUI, or working with ObservationRegistrar and Observations async sequences.

The complete Swift Programming Language book by Apple, covering syntax, features, concurrency, and the formal language reference.

A collection of tools for making navigation in Swift applications more ergonomic and powerful across SwiftUI, UIKit, and AppKit

Apple Core Bluetooth framework for BLE and Bluetooth Classic. Use for central/peripheral workflows, scanning, connecting, advertising, GATT services/characteristics, read/write/notify, L2CAP, background processing or state restoration, and error handling across Apple platforms.

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 to async/await, (6) @MainActor, Sendable, or actor isolation, (7) concurrent code architecture or performance optimization, (8) concurrency-related linter warnings (SwiftLint or similar; e.g. async_without_await, Sendable/actor isolation/MainActor lint).
