Objective c 获取Apple Mach-O链接器错误-尝试构建时[如果清理项目，则无错误，但在尝试构建项目时，它再次出现！]

使用核心数据，我试图创建一个简单的乳制品类应用程序。但当我试图编译时，我遇到了如下错误：

Apple Mach-O Linker Error 
Linker command failed with exit code 1 (use -v to see invocation)

为了解决这个问题，我删除了所有额外的代码并清理了代码，并尝试了很多方法，通过以下链接：但仍然没有解决方案

完整错误如下所示：

更新：刚刚添加了项目文件夹图片

---

在编译源代码中检查这两个文件：：NewEntryViewController和日记

---

签入构建阶段有一些.m文件添加到twicei，我试图手动解决。但我还是没有找到。是否有任何方法可以检查重复的文件。请在代码中检查这两个文件：：：NewEntryViewController和Diary我从资源管理器中进行了检查，但没有重复的文件！只需查看我的项目文件夹。没有复制品！转到Windows-Projects，并点击删除项目的派生数据文件夹。然后再试一次。
