Skills9

ios-app-intentsskills/ios-app-intents/SKILL.md

Design App Intents, app entities, and App Shortcuts for iOS system surfaces. Use when exposing app actions or content to Shortcuts, Siri, Spotlight, widgets, or controls.

ios-debugger-agentskills/ios-debugger-agent/SKILL.md

Build, run, and debug iOS apps on Simulator with XcodeBuildMCP. Use when launching an app, inspecting simulator UI or logs, or diagnosing runtime behavior.

ios-ettrace-performanceskills/ios-ettrace-performance/SKILL.md

Capture and interpret iOS Simulator ETTrace profiles. Use when profiling launch or runtime latency, comparing traces, or finding CPU-heavy stacks.

ios-memgraph-leaksskills/ios-memgraph-leaks/SKILL.md

Capture and inspect iOS leaks and memgraphs. Use when debugging leaked objects, retain cycles, memory growth, or before/after leak evidence.

ios-simulator-browserskills/ios-simulator-browser/SKILL.md

Mirror an iOS Simulator into the Codex in-app browser and render SwiftUI previews from importable Swift packages in that simulator with hot reload. Use when a user wants to watch or interact with an iOS app in the browser, see a SwiftUI preview outside Xcode Canvas, iterate live on a preview, or capture browser-visible simulator proof.

swiftui-liquid-glassskills/swiftui-liquid-glass/SKILL.md

Implement and review iOS 26+ SwiftUI Liquid Glass UI. Use when adopting Liquid Glass or checking its correctness, performance, and design fit.

swiftui-performance-auditskills/swiftui-performance-audit/SKILL.md

Audit SwiftUI runtime performance from code first. Use when diagnosing slow rendering, janky scrolling, expensive updates, or profiling needs.

swiftui-ui-patternsskills/swiftui-ui-patterns/SKILL.md

Build and refactor SwiftUI UI with component patterns and examples. Use when shaping navigation, state, layouts, controls, or screen composition.

swiftui-view-refactorskills/swiftui-view-refactor/SKILL.md

Refactor SwiftUI view files into stable, testable structure. Use when splitting large views, tightening data flow, or cleaning Observation ownership.
