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.

我不知道为什么会发生这种情况，但解决你的问题的一种方法是进入你的构建设置并定义框架搜索路径到一个包含有问题的框架的文件夹。如果框架放在您的项目目录中，只需将框架搜索路径设置为$(SRCROOT)并将其设置为递归。

我也遇到过这个问题。对我来说，修复是两个项目之间的存档方案不匹配。我有一个xcworkspace与框架项目和应用程序项目。问题在于，在我的应用程序的存档方案中，我使用了与框架的存档方案不同的构建配置。我把两个构建配置都设置为发布，这就解决了这个问题。

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。

我安装了pod Fakery, pod被添加到我的Pods文件下，但是当我尝试使用它时，我得到了同样的错误。问题是，我没有构建它，在构建它之后，swift编译器在Fakery swift文件中抛出了一些错误，一些函数已经被重命名，它也为它们提供了修复。在解决了所有这些编译器问题后，构建成功了，我能够使用模块。所以快速的语言兼容性是我的问题。

有时你必须安装pod。

打开终端 cd项目 圆荚体安装 打开.xcworkspace和 构建是成功的
