Implementation Reference
- The main handler function that launches the app in the specified iOS simulator with log capture enabled, returns session ID or error.
export async function launch_app_logs_simLogic( params: LaunchAppLogsSimParams, executor: CommandExecutor = getDefaultCommandExecutor(), logCaptureFunction: LogCaptureFunction = startLogCapture, ): Promise<ToolResponse> { log('info', `Starting app launch with logs for simulator ${params.simulatorId}`); const captureParams = { simulatorUuid: params.simulatorId, bundleId: params.bundleId, captureConsole: true, ...(params.args && params.args.length > 0 ? { args: params.args } : {}), } as const; const { sessionId, error } = await logCaptureFunction(captureParams, executor); if (error) { return { content: [createTextContent(`App was launched but log capture failed: ${error}`)], isError: true, }; } return { content: [ createTextContent( `App launched successfully in simulator ${params.simulatorId} with log capture enabled.\n\nLog capture session ID: ${sessionId}\n\nNext Steps:\n1. Interact with your app in the simulator.\n2. Use 'stop_and_get_simulator_log({ logSessionId: "${sessionId}" })' to stop capture and retrieve logs.`, ), ], isError: false, }; } - Zod schema definition for tool parameters: simulatorId, bundleId, optional args. Includes public schema omitting simulatorId and inferred type.
