好的，我无法完成您的项目构建，但是来自如何在iOS应用程序之间共享钥匙串数据我认为你可能想检查您的权利文件。至少在github项目中，您没有在Keychain Access Groups中指定任何内容。

Okay, I couldn't quite get your project to build, but from How to share keychain data between iOS applications I think you might want to check your entitlements file. At least in the github project you didn't have anything specified in the Keychain Access Groups.
