This skill should be used when writing or reviewing Swift code for iOS or macOS projects. Apply modern Swift 6+ best practices, concurrency patterns, API design guidelines, and migration strategies. Covers async/await, actors, MainActor, Sendable, typed throws, and Swift 6 breaking changes. Keywords: concurrency, async-await, actors, Sendable, typed-throws, Swift-6, migration, data-races, MainActor, nonisolated, isolated, iOS, macOS, SwiftUI, Combine, Swift-concurrency, actor-isolation, strict-concurrency, Swift-migration, modern-Swift, Swift-evolution, code-review, Swift-patterns, Apple-platforms, Xcode, iOS-development, macOS-development
Free disk space on macOS using an interactive CLI that clears caches, logs, Homebrew, Xcode junk, and more
Build professional native macOS apps in Swift with SwiftUI and AppKit. Full lifecycle - build, debug, test, optimize, ship. CLI-only, no Xcode.
This skill should be used when the user asks to "set up a fresh Mac for development", "install Homebrew and Node on macOS", "prepare a new MacBook for coding", "install Xcode Command Line Tools", "install uv Python on Mac", or "fix missing node/npm/npx on macOS".
Mobile app debugging for iOS, Android, cross-platform frameworks. Use for crashes, memory leaks, performance issues, network problems, or encountering Xcode instruments, Android Profiler, React Native debugger, native bridge errors.
Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.
Configures and enforces SwiftLint in Swift projects using build tool plugins, run scripts, and CI. Covers .swiftlint.yml configuration, disabled_rules, opt_in_rules, only_rules, analyzer_rules, baselines, autocorrect, swiftlint:disable suppressions, reporter formats (sarif, json, checkstyle), strict and lenient modes, SwiftLintBuildToolPlugin via SimplyDanny/SwiftLintPlugins, swift package plugin swiftlint, Xcode run script phases, CI integration, multiple configuration files, and rollout strategies for existing codebases. Use when setting up SwiftLint, configuring lint rules, suppressing warnings, creating baselines, choosing between build tool plugin and run script, or integrating SwiftLint into CI.
Controls a running iOS, iPad, or Apple Watch Simulator via the serve-sim CLI (npx serve-sim) and streams it into the host agent's preview pane. Use whenever the user wants an AI agent to view or drive an Apple Simulator — streaming to preview, taps at normalized coordinates, multi-touch gestures, hardware buttons, rotation, memory warnings, CoreAnimation debug, synthetic camera injection, media drag-drop, or managing app privacy permissions. Triggers include "serve-sim", "iOS simulator", "Apple simulator", "iPad simulator", "Apple Watch simulator", "stream the simulator", "show the simulator in preview", "view the simulator here", "open simulator in preview", "simulator gestures", "tap on the simulator", "rotate the simulator", "inject camera feed", "grant simulator permissions", "allow push notifications in the simulator", or any request to drive or display an Apple Simulator visually. Do NOT use for Android emulators, building/installing an iOS app (use xcodebuild), booting a simulator from scratch (use xcrun simctl boot), in-app React Native runtime debugging (use rn-debugger), or real iOS hardware.
Use when implementing internationalization (i18n), String Catalogs, pluralization, or right-to-left layout support. Covers modern localization workflows with Xcode String Catalogs and LocalizedStringKey patterns.
Expert guidance on building, debugging, and testing multiplatform iOS/Android apps and frameworks with Skip (skip.dev). Use when developers mention: (1) Skip, Skip.dev, skip-tools, or SkipStack, (2) building a multiplatform iOS+Android app from Swift/SwiftUI, (3) Skip Fuse (native) or Skip Lite (transpiled) modes, (4) transpiling Swift to Kotlin, (5) SwiftUI to Jetpack Compose bridging, (6) skip.yml configuration, (7) debugging Android builds from Xcode, (8) Skip CLI commands (skip create/init/test/export), (9) conditional compilation with #if SKIP or #if os(Android), (10) Skip Comments (SKIP INSERT/REPLACE/DECLARE/NOWARN), (11) bridging Swift and Kotlin code, (12) Skip module dependencies or Android Gradle configuration.
LLDB debugger skill for C/C++/Swift/Objective-C programs. Use when debugging with LLDB on macOS, FreeBSD, or Linux-clang environments, mapping GDB mental models to LLDB commands, using LLDB in Xcode or VS Code, or debugging Swift/Objective-C. Activates on queries about LLDB commands, GDB to LLDB migration, Apple platform debugging, LLDB Python scripting, or IDE-integrated debugging with clang-built binaries.
