对我来说，编辑方案->运行，并将调试配置从发布更改为调试解决问题。

我在开发自己的第一款应用时也遇到了同样的问题

使用.xcodeproj打开项目

Xcode辞职

从.xcworkspace重新打开项目

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.

如果你使用CocoaPods，试着注释掉(#)新的pod，运行pod install，把它带回来，然后再次安装pod。有时somewhy pod脚本不能产生正确的依赖关系(或者与运行xCode冲突?)所以它有时确实有帮助

我仍然不能从xcode存档，但fastlane为我做了这项工作

在我的情况下，我尝试了上面的每一个建议仍然没有工作。 我只是复制文件的内容，显示错误没有导入的东西，并将其粘贴到另一个文件相同的导入和注释错误文件。 再次运行项目，它工作，然后我删除原来的错误文件，并创建一个同名的文件，并使其内容再次使用相同的导入。 我认为在我的情况下，我只是想办法让它能够链接那些导入一次，它应该是好的。
