    react native 0.68.2,if this error comes to you

    you should change the file under

    node_modules/@react-native-community/cli-platform-ios/build/config/index.js

    function dependencyConfig(folder, userConfig) {
  comment this line
  // const configurations = userConfig.configurations || [];
     
  // redeclare again
 var configurations="";

    we just needs to upgrade @react-native-community/cli

    npm i -g @react-native-community/[email protected]
