react-native 出现 Could not find iPhone 6 simulator 与 ":CFBundleIdentifier", Does Not Exist

• 升级Xcode 版本发现运行 react-native run-ios 时出现

Could not find iPhone 6 simulator

找到并修改项目下 /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js 文件

    // 注释掉这部分
    // if (version.indexOf('iOS') !== 0) {
    //   continue;
    // }

    // 添加
    if (version.indexOf('iOS') !== 0 && !version.includes('iOS')) {
      continue;
    }

重新尝试 react-native run-ios 或者指定模拟器型号 react-native run-ios --simulator="iPhone 6"

• 仍然出现 ":CFBundleIdentifier", Does Not Exist

先删除全部node依赖
rm -rf node_modules

升级 react-native 
react-native upgrade

安装依赖并 重新上面的修改
yarn install 

重新尝试 react-native run-ios
