• 进入项目工程目录下(找到这个findMatchingSimulator.js 并修改)
• /node_modules/react-native/local-cli/runIOS/findMatchingSimulator.js

/* 修改 simulators 的判断*/
if (!version.startsWith('iOS') && !version.startsWith('tvOS')) {
      continue;
    }
/*修改成如下*/
if (!version.includes('iOS')) {
      continue;
    }

重新 react-native run-ios即可
