Go to edit scheme as shown below.
转到如下所示的编辑方案。
then uncheck all other targets except your main target under build tab.

I recently got this error under different circumstances. Running Ionic, updating my ios platform from 3.8.0 to 4.0.1 I discovered this error.
我最近在不同的情况下遇到了这个错误。运行 Ionic，将我的 ios 平台从 3.8.0 更新到 4.0.1 我发现了这个错误。
I had to disable bitcode in my app.
我不得不在我的应用程序中禁用位码。
To do this, click your top level app icon in the file structure. In the main window, click the header build settings. In the search bar, type bit (or bitcode) and you should see enable bit code beneath
为此，请单击文件结构中的顶级应用程序图标。在主窗口中，单击标题构建设置。在搜索栏中，键入 bit（或 bitcode），您应该会在下方看到启用位代码
I had disabled it before, but I'm guessing that updating the ios platform enables bitcode so it needed to be disabled again.
我之前禁用了它，但我猜更新 ios 平台会启用位码，因此需要再次禁用它。

No need to mess with schemes. Just go to build settings for your targets or project and turn off Bitcode.
没有必要搞乱计划。只需为您的目标或项目构建设置并关闭 Bitcode。

Real Issue
真正的问题
After changing the PRODUCT_NAME(as seen in the question) the erroneous reference to Host Applicationis the real cause of the issue.
更改后PRODUCT_NAME（如问题所示）对主机应用程序的错误引用是问题的真正原因。
Just select your Tests-Target and under the General-Tab select your updated Host Application.
只需选择您的 Tests-Target 并在 General-Tab 下选择您更新的 Host Application。
Afterwards, building the project will work.
之后，构建项目将起作用。

If you see this error without detail result then check 'enum' in header file. Move them in .m file.
如果您在没有详细结果的情况下看到此错误，请检查头文件中的“枚举”。将它们移动到 .m 文件中。

By deleting the derived data Xcode will recompile and regenerate the data for you.
通过删除派生数据，Xcode 将为您重新编译并重新生成数据。
You can do that by going to: Windows -> projects Delete derived data
