ios-debugger-agent
Build, run, and debug iOS apps on a booted simulator with UI interaction and log capture.
- Discovers booted simulators, sets session defaults (project path, scheme, simulator ID), and builds/runs the current iOS project via XcodeBuildMCP tools
- Provides UI inspection (
describe_ui,screenshot), interaction commands (tap,type_text,gesture), and element targeting by ID, label, or coordinates - Captures simulator logs and console output with start/stop controls; includes build failure detection and retry logic with optional Xcodebuild fallback
- Follows a structured workflow: discover simulator, set defaults, build/run, verify launch, then interact or debug based on user requests
iOS Debugger Agent
Overview
Use XcodeBuildMCP to build and run the current project scheme on a booted iOS simulator, interact with the UI, and capture logs. Prefer the MCP tools for simulator control, logs, and view inspection.
Core Workflow
Follow this sequence unless the user asks for a narrower action.
1) Discover the booted simulator
- Call
mcp__XcodeBuildMCP__list_simsand select the simulator with stateBooted. - If none are booted, ask the user to boot one (do not boot automatically unless asked).
2) Set session defaults
- Call
mcp__XcodeBuildMCP__session-set-defaultswith:projectPathorworkspacePath(whichever the repo uses)schemefor the current appsimulatorIdfrom the booted device- Optional:
configuration: "Debug",useLatestOS: true

swiftui-performance-audit
Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient.
6.9Kswiftui-liquid-glass
Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
2.9Kswiftui-ui-patterns
Best practices and example-driven guidance for building SwiftUI views and components, including navigation hierarchies, custom view modifiers, and responsive layouts with stacks and grids. Use when creating or refactoring SwiftUI UI, designing tab architecture with TabView, composing screens with VStack/HStack, managing @State or @Binding, building declarative iOS interfaces, or needing component-specific patterns and examples.
2.3Kswiftui-view-refactor
Refactor and review SwiftUI view files with strong defaults for small dedicated subviews, MV-over-MVVM data flow, stable view trees, explicit dependency injection, and correct Observation usage. Use when cleaning up a SwiftUI view, splitting long bodies, removing inline actions or side effects, reducing computed `some View` helpers, or standardizing `@Observable` and view model initialization patterns.
1.5Kswift-concurrency-expert
Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file. Concrete actions include adding Sendable conformance, applying @MainActor annotations, resolving actor isolation warnings, fixing data race diagnostics, and migrating completion handlers to async/await.
1.2Kapp-store-changelog
Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags.
