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 mcp__XcodeBuildMCP__list_sims 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 mcp__XcodeBuildMCP__session-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 mcp__XcodeBuildMCP__build_run_sim.
• 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 mcp__XcodeBuildMCP__describe_ui or mcp__XcodeBuildMCP__screenshot before proceeding to UI in
