我在使用Cocoapods和Swift时也遇到了同样的问题。我没有注意到Podfile中的以下行:

# Uncomment this line if you're using Swift
# use_frameworks!

所以，我所要做的就是把它改成:

# Uncomment this line if you're using Swift
use_frameworks!

.．.啊，它起作用了:)

假设框架真的在那里，在道路上，等等……删除~/Library/Developer/Xcode/DerivedData/ModuleCache目录(清理项目并删除项目特定的派生数据)。

在执行标准清理时，不会重新构建ModuleCache目录。

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.

确保项目文件夹不在iCloud Drive中。

当框架没有正确编译时也会发生这种情况。

在Xcode中打开框架项目，看看Product→Build是否成功。

一旦在框架中修复了构建错误，打开主项目，看看是否可以导入框架。

实际上，通过添加到build-debug.xconfig的末尾，我更容易地解决了这个问题

#包括“. ./Pods/目标支持文件/Pods- iap /Pods- iap .debug.xcconfig"

一直到build-release.xconfig的末尾

#包括“. ./Pods/目标支持文件/Pods- iap /Pods- iap .release.xcconfig"

因为这些文件已经定义了PODS_ROOT和相关的构建变量。
