Symbol not found: _OBJC_CLASS_$_EMMessage错误问题

我在github声网-用例下载的demo(https://github.com/AgoraIO-Usecase/AgoraMeeting-iOS),按照操作步骤,运行项目之后,报出下面错误:

dyld[19593]: Symbol not found: OBJC_CLASS$_EMMessage

我在Build Phases 添加了上述文件,还是没有效果,所以能告诉我,该添加那些文件呢

看起来像框架问题。
可以参考下网上解决方案: dyld: Symbol not found: OBJC_CLASS$_xxxx 错误闪退 - JavaShuo
