9. run-on-device

Builds, installs, and runs an app on a physical iOS device. Supports device name (including Korean names) or UUID for device selection, environment variables, and log streaming. Now with direct bundleId specification, skip build option, and additional launch arguments.

Parameters:

projectPath (required): Path to the Xcode project (.xcodeproj) or workspace (.xcworkspace)
scheme (required): The scheme to build and run
device (required): Device identifier or name (supports Korean names)
configuration (optional): Build configuration (e.g., Debug, Release)
streamLogs (optional): Whether to stream device logs after launching
startStopped (optional): Whether to start the app in a paused state for debugger attachment
environmentVars (optional): Environment variables to pass to the app (key1=value1,key2=value2 format)
xcodePath (optional): Xcode application path (default: "/Applications/Xcode-16.2.0.app")
listDevices (optional): Display all detected devices with their IDs before running
skipBuild (optional): Skip the build and install step for already installed apps
extraLaunchArgs (optional): Additional arguments to pass to the devicectl launch command
directBundleId (optional): Directly specify the bundle ID instead of extracting from project

Example:

Project path: /Users/username/Projects/MyApp/MyApp.xcodeproj
Scheme: MyAppScheme
Device: "Your-iPhone"
Configuration: Debug
StreamLogs: true
EnvironmentVars: "DEBUG_MODE=1,API_URL=https://test-api.example.com"

Process:

The tool identifies both Xcode UDID and CoreDevice UUID for the specified device
It uses the Xcode UDID for building and installing the app
It uses the CoreDevice UUID for launching the app with devicectl
It retrieves the app's bundle identifier
If requested, it streams the device logs

Key Improvements in v0.4.0:

Ability to specify bundleId directly without needing a project
Skip build and install step for already installed apps
Support for additional devicectl launch command arguments
Better device model and OS version information display
Improved path handling and logging for devicectl commands

Sample Output:

// Standard output with build and install
앱 실행 결과:
Launched application with com.example.myapp bundle identifier.
로그 스트리밍이 시작되었습니다. 로그는 터미널에서 확인할 수 있습니다.

// Direct bundle ID usage with skip build
기기 모델: iPhone14,7
기기 OS 버전: 17.0
사용자 지정 번들 ID 사용: com.example.myapp
빌드 및 설치 과정 건너뛰기
앱 실행 결과:
Launched application with com.example.myapp bundle identifier.

Example Scenario: Using with LLMs

Below is an example of how you might prompt an LLM like Claude to use these tools in sequence:

User Prompt to Claude:

I need to inspect my Xcode project, run some tests, and then archive it for distribution.

First, use the xcode-list-schemes tool to get all available schemes for my project at /Users/username/Projects/MyApp/MyApp.xcodeproj
After you see the schemes, run tests for the first available scheme on the iPhone 14 simulator.
Then archive the app for distribution using the Release configuration.

Expected Workflow:

Claude will execute the xcode-list-schemes tool to retrieve all schemes:
Project path: /Users/username/Projects/MyApp/MyApp.xcodeproj
Claude will execute the xcode-test tool with the identified scheme:
Project path: /Users/username/Projects/MyApp/MyApp.xcodeproj Scheme: [First scheme from output] Destination: platform=iOS Simulator,name=iPhone 14
Claude will then use the xcode-archive tool to create an archive:
Project path: /Users/username/Projects/MyApp/MyApp.xcodeproj Scheme: [First scheme from output] Configuration: Release ArchivePath: /Users/username/Desktop/MyApp.xcarchive

This workflow demonstrates how to chain multiple tools together, using the output from one tool to inform the parameters for another.

Example: Running on a Real Device

User Prompt to Claude:

I need to test my app on a real device:

1. Get the list of available devices (including connected physical devices)
2. Run my app on my connected iPhone 

Expected Workflow:

Claude will first get the list of devices:
listDevices: true
Claude will identify your physical device and run the app on it:
Project path: /Users/username/Projects/MyApp/MyApp.xcodeproj Scheme: MyApp Device: "Your iPhone" (or the device UUID) StreamLogs: true
For quick re-launch without rebuilding:
Device: "Your iPhone" DirectBundleId: "com.example.myapp" SkipBuild: true

Security Considerations

This tool can execute Xcode-related commands, which poses security risks. Please note:

Only use with trusted Xcode projects.
Be cautious with projects from unknown sources.
Do not include sensitive information in build parameters.
