What this skill does
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. When to Use When the user asks to run, debug, or inspect an iOS app on a simulator. When you need simulator UI interaction, screenshots, or runtime logs via XcodeBuildMCP. Core Workflow Follow this sequence unless the user asks for a narrower action. 1) Discover the booted simulator Call mcpXcodeBuildMCPlistsims and select the simulator with state Booted. If none are booted, ask the user to boot one (do not boot automatically unless asked). 2) Set session defaults Call mcpXcodeBuildMCPsession-set-defaults with: projectPath or workspacePath (whichever the repo uses) scheme for the current app simulatorId from the booted device Optional: configuration: "Debug", useLatestOS: true 3) Build + run (when requested) Call mcpXcodeBuildMCPbuildrunsim. If the build fails, check the error output and retry (optionally with preferXcodebuild: true) or escalate to the user before attempting any UI interaction. After a successful build, verify the app launched by calling mcpXcodeBuildMCPdescribeui or mcpXcodeBuildMCPscreenshot before proceeding to UI interaction. If the app is already built and only launch is requested, use mcpXcodeBuildMCPlaunchappsim. If bundle id is unknown: 1) mcpXcodeBuildMCPgetsimapppath 2) mcpXcodeBuildMCPgetappbundleid UI Interaction & Debugging Use these when asked to inspect or interact with the running app. Describe UI: mcpXcodeBuildMCPdescribeui before tapping or swiping. Tap: mcpXcodeBuildMCPtap (prefer id or label; use coordinates only if needed). Type: mcpXcodeBuildMCPtypetext after focusing a field. Gestures: mcpXcodeBuildMCPgesture for common scrolls and edge swipes. Screenshot: mcpXcodeBuildMCPscreenshot for visual confirmation. Logs & Console Output Start logs: mcpXcodeBuildMCPstartsimlogcap with the app bundle id. …
