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_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 app is already built and only launch is requested, use
```
mcp__XcodeBuildMCP__launch_app_sim
```
.

If bundle id is unknown:

```
mcp__XcodeBuildMCP__get_sim_app_path
```
```
mcp__XcodeBuildMCP__get_app_bundle_id
```

UI Interaction & Debugging

Use these when asked to inspect or interact with the running app.

Describe UI:
```
mcp__XcodeBuildMCP__describe_ui
```
before tapping or swiping.
Tap:
```
mcp__XcodeBuildMCP__tap
```
(prefer
```
id
```
or
```
label
```
; use coordinates only if needed).
Type:
```
mcp__XcodeBuildMCP__type_text
```
after focusing a field.
Gestures:
```
mcp__XcodeBuildMCP__gesture
```
for common scrolls and edge swipes.
Screenshot:
```
mcp__XcodeBuildMCP__screenshot
```
for visual confirmation.

Logs & Console Output

Start logs:
```
mcp__XcodeBuildMCP__start_sim_log_cap
```
with the app bundle id.
Stop logs:
```
mcp__XcodeBuildMCP__stop_sim_log_cap
```
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
```
describe_ui
```
after layout changes.
