Implementation Reference

• src/tools/build_ios_simulator.ts:42-70 (handler)

  Core internal handler that executes the xcodebuild build command for iOS simulator targeting, shared across similar tools.
  async function _handleIOSSimulatorBuildLogic(params: { workspacePath?: string; projectPath?: string; scheme: string; configuration: string; simulatorName?: string; simulatorId?: string; useLatestOS: boolean; derivedDataPath?: string; extraArgs?: string[]; preferXcodebuild?: boolean; }): Promise<ToolResponse> { log('info', `Starting iOS Simulator build for scheme ${params.scheme} (internal)`); return executeXcodeBuildCommand( { ...params, }, { platform: XcodePlatform.iOSSimulator, simulatorName: params.simulatorName, simulatorId: params.simulatorId, useLatestOS: params.useLatestOS, logPrefix: 'iOS Simulator Build', }, params.preferXcodebuild, 'build', ); }
• src/tools/build_ios_simulator.ts:511-557 (registration)

  Registers the 'build_ios_sim_id_proj' tool with name, description, input schema, validation, and delegation to core handler.
  export function registerIOSSimulatorBuildByIdProjectTool(server: McpServer): void { type Params = { projectPath: string; scheme: string; simulatorId: string; configuration?: string; derivedDataPath?: string; extraArgs?: string[]; useLatestOS?: boolean; preferXcodebuild?: boolean; }; registerTool<Params>( server, 'build_ios_sim_id_proj', "Builds an iOS app from a project file for a specific simulator by UUID. IMPORTANT: Requires projectPath, scheme, and simulatorId. Example: build_ios_sim_id_proj({ projectPath: '/path/to/MyProject.xcodeproj', scheme: 'MyScheme', simulatorId: 'SIMULATOR_UUID' })", { projectPath: projectPathSchema, scheme: schemeSchema, simulatorId: simulatorIdSchema, configuration: configurationSchema, derivedDataPath: derivedDataPathSchema, extraArgs: extraArgsSchema, useLatestOS: useLatestOSSchema, preferXcodebuild: preferXcodebuildSchema, }, async (params: Params) => { // Validate required parameters const projectValidation = validateRequiredParam('projectPath', params.projectPath); if (!projectValidation.isValid) return projectValidation.errorResponse!; const schemeValidation = validateRequiredParam('scheme', params.scheme); if (!schemeValidation.isValid) return schemeValidation.errorResponse!; const simulatorIdValidation = validateRequiredParam('simulatorId', params.simulatorId); if (!simulatorIdValidation.isValid) return simulatorIdValidation.errorResponse!; // Provide defaults return _handleIOSSimulatorBuildLogic({ ...params, configuration: params.configuration ?? 'Debug', useLatestOS: params.useLatestOS ?? true, // May be ignored by xcodebuild preferXcodebuild: params.preferXcodebuild ?? false, }); }, ); }
• src/tools/common.ts:22-62 (schema)

  Zod schemas for common parameters used in the tool's input schema, including projectPath, scheme, simulatorId, etc.
  export const workspacePathSchema = z.string().describe('Path to the .xcworkspace file (Required)'); export const projectPathSchema = z.string().describe('Path to the .xcodeproj file (Required)'); export const schemeSchema = z.string().describe('The scheme to use (Required)'); export const configurationSchema = z .string() .optional() .describe('Build configuration (Debug, Release, etc.)'); export const derivedDataPathSchema = z .string() .optional() .describe('Path where build products and other derived data will go'); export const extraArgsSchema = z .array(z.string()) .optional() .describe('Additional xcodebuild arguments'); export const simulatorNameSchema = z .string() .describe("Name of the simulator to use (e.g., 'iPhone 16') (Required)"); export const simulatorIdSchema = z .string() .describe('UUID of the simulator to use (obtained from listSimulators) (Required)'); export const useLatestOSSchema = z .boolean() .optional() .describe('Whether to use the latest OS version for the named simulator'); export const appPathSchema = z .string() .describe('Path to the .app bundle (full path to the .app directory)'); export const bundleIdSchema = z .string() .describe("Bundle identifier of the app (e.g., 'com.example.MyApp')"); export const launchArgsSchema = z .array(z.string()) .optional() .describe('Additional arguments to pass to the app'); export const preferXcodebuildSchema = z .boolean() .optional() .describe( 'If true, prefers xcodebuild over the experimental incremental build system, useful for when incremental build system fails.', );
• src/utils/register-tools.ts:231-235 (registration)

  Central registration entry that invokes registerIOSSimulatorBuildByIdProjectTool during server initialization if enabled.
  { register: registerIOSSimulatorBuildByIdProjectTool, groups: [ToolGroup.IOS_SIMULATOR_WORKFLOW], envVar: 'XCODEBUILDMCP_TOOL_IOS_SIMULATOR_BUILD_BY_ID_PROJECT', },
