ios-debugger-agent

Use XcodeBuildMCP to build, run, launch, and debug the current iOS project on a booted simulator. Trigger when asked to run an iOS app, interact with the simulator UI, inspect on-screen state, capture logs/console output, or diagnose runtime behavior using XcodeBuildMCP tools.

Why this skill is useful

Adds executable scripts for building, running, and debugging iOS apps on simulators that are not publicly documented.

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. 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 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. Stop logs: mcpXcodeBuildMCPstopsimlogcap and summarize important lines. For console output, set captureConsole: true and relaunch if required. Troubleshooting If build fails, ask whether to retry with preferXcodebuild: true. If the wrong app launches, confirm the scheme and bundle id. If UI elements are not hittable, re-run describeui after layout changes.
