I recently just upgraded to the new XCode. After I upgraded, some of my apps won't build. I get this error:

ld: cannot link directly with /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/usr/lib/system/libcommonCrypto.dylib.  Link against the umbrella framework 'System.framework' instead. for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried everything - cleaning, reimporting, changing architectures...

Please help

ios xcode armv7
