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.

几天前我也遇到了同样的错误。下面是我解决这个问题的方法:

错误是“模块未找到”

Create Podfile in your root project directory Install cocoapods (a dependency manager for Swift and iOS projects) Run pod install Go to Project Build Settings: Find Objective-c bridging Header under Swift compiler - Code Generation (If you don't find Swift compiler here, probably add a new Swift file to the project) Drag and drop the library header file from left side to bridging header (see image attached) Create a new bridging header file: e.g TestProject-Bridging-Header.h and put under Swift Compiler → Objective-C Generated Interface Header Name (ref, see the image above) In TestProject-Bridging-Header.h file, write #import "Mixpanel/Mixpanel.h" In your Swift file the code should be: Import Mixpanel (i.e name of library)

这是所有。

请将此截图与您的构建设置进行比较。 这可能会奏效。 进入框架搜索路径:

我得到了相同的错误

import Firebase

但随后注意到，我没有将pod添加到主目标部分，而只是在Podfile中添加到Test和TestUI目标。

用命令

pod init

对于xcode swift项目，会生成以下Podfile

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyAppUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

因此，需要确保将pod添加到任何适当的占位符。

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

在General =>链接框架和库中，我添加了。/Pods/Pods。Xcodeproj成功了
