我刚刚删除了我的cocoapod。然后，我做了一个豆荚安装来移除它。然后，我只是把它添加回我的podfile，并重新安装它。这让它成功了。不知道为什么。

有时豆荚分解，然后豆荚安装也帮助我。

检查你是否使用最新版本的xcode。(如果没有更新到您设备支持的最新版本)。 用sudo gem Install cocoapods安装cocoapods 运行吊舱设置

我可以确认以上步骤解决了我的错误:-)

对于Xcode 10+和项目，还有一个建议。创建Xcode版本< 10,2。包含带有主项目所依赖的框架的子项目。问题是Xcode会将编译后的框架放在子项目中指定的目录中，这可能与主项目的构建目录不同。

检查文件>项目设置。现在，单击“Advanced…”并选择“Legacy”以外的内容作为构建路径，例如，“Unique”。在这种情况下，Xcode将把所有构建的组件放到一个文件夹中，它应该能够找到“丢失”的模块。

有几个潜在的错误配置可能会导致这个问题，

Please confirm that you have opened the .xcworkspace but not .xcodeproj file. Also make sure you have build Social first before you build TriviaApp. Make sure that iOS Deployment Target is set same for all modules with main app. For example is TriviaApps deployment target is set to 9.0, Socials deployment target also need to be set to 9.0. Make sure your main module (TriviaApp) and your used framework (Social) have same set of configurations. i.e. If your Project has three configurations, Debug, Release, ReleasePremium than your Social framework also need to have three configurations Debug, Release, ReleasePremium. Also make sure that the archive configuration is set same for both TriviaApp and Social. i.e. if your TriviaApps archive scheme is set to ReleasePremium, your Socials archive scheme also need to be set into ReleasePremium. Please assure that you do not need to import Social in each .swift files when its already added in the Bridging-Header.h. In case of issue came from Pod files, make sure you have uncommented #use_frameworks! into use_frameworks! from you Podfile. Sometime re installing pod works if Social has any dependency on pods. If none of the above steps works, delete your derived data folder and try re building.

没想到这竟然起作用了。我的解决办法是……

构建设置->框架搜索路径->高亮调试->按delete ->它应该自动填写一个路径。->释放时执行同样的操作

结果:
