补充上一篇上传代码到CocoaPods库第7步报错修改

通过pod spec lint 检查命令报这个错误。

• ERROR | [iOS] unknown: Encountered an unknown error (Could not find aIOS simulator (valid values: ). Ensure that Xcode -> Window -> Devices has at least oneIOSsimulator listed or otherwise add one.) during validation.

解决办法：升级更新pod就好了，亲测有效

CocoaPods 1.8.3 is available.

To update use: gem install cocoapods

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.8.3

使用 gem install cocoapods 命令升级到最新版本，就不再报错了
