+description: Official skill for XcodeBuildMCP. Use when doing iOS/macOS/watchOS/tvOS/visionOS work (build, test, run, debug, log, UI automation).

+
+# XcodeBuildMCP
+
+Use XcodeBuildMCP tools instead of raw `xcodebuild`, `xcrun`, or `simctl`.
+
+Capabilities:
+- Session defaults: Configure project, scheme, simulator, and device defaults to avoid repetitive parameters
+- Project discovery: Find Xcode projects/workspaces, list schemes, inspect build settings
+- Simulator workflows: Build, run, test, install, and launch apps on iOS simulators; manage simulator state (boot, erase, location, appearance)
+- Device workflows: Build, test, install, and launch apps on physical devices with code signing
+- macOS workflows: Build, run, and test macOS applications
+- Log capture: Stream and capture logs from simulators and devices
+- LLDB debugging: Attach debugger, set breakpoints, inspect stack traces and variables, execute LLDB commands
+- UI automation: Capture screenshots, inspect view hierarchy with coordinates, perform taps/swipes/gestures, type text, press hardware buttons
+- SwiftPM: Build, run, test, and manage Swift Package Manager projects
+- Project scaffolding: Generate new iOS/macOS project templates
+
+Only simulator workflow tools are enabled by default. If capabilities like device, macOS, debugging, or UI automation are not available, the user must configure XcodeBuildMCP to enable them. See https://xcodebuildmcp.com/docs/configuration for workflow configuration.
+
+## Step 1: Establish Session Context
+
+- Call `session_show_defaults` before the first build/run/test action in a session.
+- Use `discover_projs` only when defaults show missing or incorrect project/workspace context.
+- Do not run discovery speculatively or in parallel with `session_show_defaults`.
+- For simulator run intent, prefer the combined build-and-run tool instead of separate build then run calls.
+- Do not chain build-only then build-and-run unless the user explicitly requests both.
+
+## Step 2: Understand Workflow-Scoped Tool Availability
+
+- Not all tools are enabled by default; tool availability depends on enabled workflows.
+- If a tool is expected but missing, check enabled workflows first.
+- Update enabled workflows in `.xcodebuildmcp/config.yaml`, then ask user to reload/restart the session to surface refreshes.
+
+## Step 3: Report Context Clearly
+
+- Return the active defaults context used for execution (project/workspace, scheme, simulator/device).
+- For failures, include the exact failing step and the next actionable command/tool call.
