ios - 【已经自己解决】Pod 验证不通过

我正在执行 命令如下:

pod lib lint XXX.podspec --verbose

代码是Objective-C写的，为什么会出现Swift的相关错误呢？

错误信息如下:

[!] TDTouchID did not pass validation, due to 2 errors.
[!] The validator for Swift projects uses Swift 3.0 by default, if you are using a different version of swift you can use a `.swift-version` file to set the version for your Pod. For example to use Swift 2.3, run: 
    `echo "2.3" > .swift-version`.
You can use the `--no-clean` option to inspect any issue.

已经解决：
重新标记了git tag
重新 提交到远程仓库 git push --tag
重新 验证就通过了
