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.

swift-concurrency

nonameplum/agent-skills

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).

swift-state-machine-patterns

nonameplum/agent-skills

Build type-safe Swift state machines with enum states and action-based transitions. Use for lifecycle or protocol flows, reentrancy-sensitive operations, or async/concurrent workflows.

2026-03-0916

swift-type-typed-design

nonameplum/agent-skills

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.

accessory-setup-kit

nonameplum/agent-skills

AccessorySetupKit for privacy-preserving discovery and setup of Bluetooth, Wi-Fi, or Wi-Fi Aware accessories. Use for discovery sessions, picker-based authorization, migration, accessory renaming or removal, custom filtering, and required Info.plist declarations.
