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

如果工作区中有多个项目，则需要:

向所有项目添加新配置 产品->清洁 删除派生数据 终端吊舱安装 构建您的项目。

在尝试了这个线程上的所有想法后，当我更新cocoapods时，它起作用了。

$ pod --version
$ 1.0.0 // should have been 1.10.0

你应该更新cocoapods

gem which cocoapods

至于xCode 12和模拟器，

当你导航到Pods时，错误可能会消失。项目导航器中的Xcodeproj， 在“排除架构”下的构建设置中，对于每个调试和发布，选择值为arm64的“任何iOS模拟器SDK”。

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.

我赢得了“没有这样的模块”错误的最愚蠢原因奖。在我的例子中，我手工构建了包含的框架，并将其复制到我的项目目录中。我的框架搜索路径设置正确，框架也被正确地添加到项目中。

当我归档我正在构建的框架时，我使用“Show in Finder”将我带到派生数据中的发布文件夹。但是我没有注意到这个文件夹只包含框架的别名，而不是框架本身。原始框架仍然在我的派生数据目录中，所以后来当我清除派生数据时，框架被删除了，但我的项目不知道这一点。

重新归档框架，遵循别名到实际框架，并将其复制到我的项目目录中，这是可行的。
