APPLE MACH-O LINKED ERROR After adding AFNetworking

Question

Just adding AFNetworking into my project, and after B&R here i got this error like:

Undefined symbols for architecture i386:
"_SecCertificateCopyData", referenced from:
  -[AFURLConnectionOperation connection:willSendRequestForAuthenticationChallenge:] in       AFURLConnectionOperation.o

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Have already checked framework,libs and compile source, or re-add AFURLConnection.m, it won't work either.

Can anyone please help me out? thanks a lot...

Answer 1

You need to add the Security.framework in order for it to build.

Answer 2

For mine, I have to add

• Security.framework
• SystemConfiguration.framework
• MobileCoreServices.framework

Answer 3

I had a very similar issue and was seeing about 15 mach -0 linker compiler error messages. Adding the security framework reduced that # to 7 errors.

Did some more research and found that you might also need to add the SystemConfiguration.framework via xCode.

This completely resolved the issue for me.

As an FYI - I was using xCode 5, targeting iOS 7 and using AFNetworking version 2.0.

Adding as an answer, in case other people find that simply adding security.framework doesnt resolve things for them.

Thanks to Cody above for the accepted answer.

Answer 4

OS X, I had to add:

• Security.framework
• SystemConfiguration.framework
