iOS开发笔记-127:swift5，转让app后，打包上传问题

在app转让后，重新打包上传appstore的时候，遇到这个报错：
Potential Loss of Keychain Access. The previous version of software has an application-identifier value of [] and the new version of software being submitted has an application-identifier of []. This will result in a loss of keychain access.

解决方法：
只是提醒，不是报错，其实包以前传上去了。
直接去appstore connect上提交审核就行。
