I am trying to use XMPPFramework with an iOS5 project (ARC) under xcode 4.2.1 but I am facing this problem. Once I add CocoaAsyncSocket to my project as part of preparing my project to use XMPPFramework as in 1I get the following error.

I have seen some other people having the "Undefined symbols for architecture armv7" but I did not find yet an answer to this particular issue I have at the moment.

I have linked to the CFNetwork and marked the GCDAsyncSocket.m as non-ARC (-fno-objc-arc) but i still get the error. Any help is appreciated. 

Undefined symbols for architecture armv7:

You just need to add SecurityFramework in the Frameworks. I also met this same problem.

    It works! I am wondering it was not indicated anywhere that the security framework is also needed. Thanks for your answer. – Future2020 Apr 08 '12 at 16:15

    Order is important: CFNetwork.framework first and then Security.framework ; it makes me 14 errors in compilation, after this fix, everything is OK. – Martin Mar 21 '13 at 16:01

    Regarding my last comment, order in: Project > Build Phases > Link Library. – Martin Mar 21 '13 at 16:20
  • I am also encountering this issue. How do I can add SecurityFramework? – shogitai Nov 08 '21 at 10:14
