带有 Objective-C 文件的 Swift Cocoapods 给出了未定义的符号

Question

I have encountered the following error message:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_VTapManager", referenced from:
      objc-class-ref in VTapManagerHelper.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Have you tried enabling dynamic frameworks? That worked for me.

To do it go to the podfile in your workspace and open it, then:

#Uncomment the next line if you're using Swift or would like to use dynamic frameworks
remove the hash here ->  #use_frameworks!

这是次要的，但不要忘了退出Xcode和安装的CocoaPods后运行yourProject.xcworkspace代替yourProject.xcodeproj
