如果Xcode在链接时报错，例如Library not found for -lPods，它不会检测到隐式依赖。

Go to Product > Edit Scheme Click on Build Add the Pods static library, and make sure it's at the top of the list Clean and build again If that doesn't work, verify that the source for the spec you are trying to include has been pulled from github. Do this by looking in /Pods/. If it is empty (it should not be), verify that the ~/.cocoapods/master//.podspec has the correct git hub url in it. If still doesn't work, check your XCode build locations settings. Go to Preferences -> Locations -> Derived Data -> Advanced and set build location to “Relative to Workspace”.

在我的例子中，问题是Xcode的派生数据位置被设置为“Legacy”选项。CocoaPods目标(libpodds .a)正在正确地构建，但Xcode在错误的地方寻找它。

将其切换为“Unique”(默认值)解决了这个问题。你可以通过去首选项>位置，然后点击高级…按钮。

您是否打开工作区(由CocoaPods生成)而不是xcodeproj?

我发现选择“查找隐式依赖项”(在product / edit scheme下)将解决这个问题，而不必将pod添加为目标。

删除CocoaPods缓存文件夹~/Library/Caches/CocoaPods和安装pod对我来说是有效的。

我有同样的问题，当我编辑Podfile添加目标，我是使用没有目标之前。

子文件

target 'xxxx' do

pod 'xyz'
pod 'abc'    

end

在四处闲逛后，我发现在目标属性>>常规选项卡>>链接框架和库部分，有新的libPods-xxxx。a和旧的libPods.a

我只是删除了libPods。A，一切都很好。
