Question

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.
