Add the relevent xcconfig files to your project. Cocoapods will have created them but you can't set them in Xcode until they are in the project. You probably want to add them to the Pods group where the other pods xcconfig files are. Right click and add files. Search for xcconfig files in your project folder or look in Pods/Target Support Files/[TARGET_NAME]/ (I have different cocoapods configured for each target (extension and main project this may be slightly different in your case) Go to project configurations in the Info of your main project For each target and configuration set the appropriate pods configuration. pod install again and you should see no errors.

也遇到了同样的问题。它可以建立在模拟器上，但不是在我的设备上。没有一个答案能帮我解决这个问题。以下是我将一些答案拼凑在一起的方法:

Changed my pods file to use a specific target: target :MyProject do pod 'AWSCognitoSync' pod 'Facebook-iOS-SDK' end Ran pod install That gives an error: [!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `MyProject` to `Pods/Target Support Files/Pods-MyProject/Pods-MyProject.debug.xcconfig` or include the `Pods/Target Support Files/Pods-MyProject/Pods-MyProject.debug.xcconfig` in your build configuration. Go Project settings and click on Info tab. There will be an error where it cannot find the Configuration file. Set it to "None" for Debug and Release. Run pod install yet again Clean and build. This works.

最简单的解决方案(在多次遇到这个问题后):

删除Podfile & Podfile。锁从你的项目库(保存Podfile的地方，这样你可以很容易地粘贴到新的Podfile) 运行'pod init' 编辑“Podfile”到你的遗嘱(添加你正在使用的pods) 运行'pod install'

这将在几分钟内重新创建所有内容并工作(不花费时间对“错误”进行逆向工程)。

别瞎捣鼓了，重置。

循序渐进的

显示项目导航器 选择项目 选择信息 在Configurations中，选择每个目标，一次一个(Debug, ApplicationUnitTest, Release，等等)，对于每个目标，将configuration设置为None。 确保“基于配置文件”为每个配置读取0配置集或无配置集。这是关键所在。 Xcode辞职 rm -rf Pods/ Podfile。锁;圆荚体安装

一旦你允许pod安装在第7步中发挥它的魔力，你就可以使用自定义配置并更改配置。

所以对我来说，这个问题是由于前面提到的xcconfig文件名在Swift 3更新发生之前被更改了。

有些东西是不同步的，所以Cocoapods创建了一个“恢复引用”文件夹部分与旧的命名文件，并链接到它们。

为了解决这个问题，我:

删除了“恢复的引用”文件夹和包含旧的 Xcode和文件系统中的.xcconfig文件 Xcode辞职 运行pod安装

从那以后，一切都为我处理好了，警告也消失了。
