_SecTrustEvaluate linking error with Google Cardboard Unity3d SDK

Question

I am trying to run the demo project that comes with the Unity3d package for Google cardboard, but I keep getting this error when I build in xCode.

Undefined symbols for architecture arm64: "_SecTrustEvaluate", referenced from: l155 in libvrunity.a(GTMSessionFetcher.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am running Unity 5.2.0f3 and Xcode 6.4. The only things I have in my project are the CardboardSDK and the demo project both downloaded from here: https://developers.google.com/cardboard/unity

Has anyone run into this problem before or know how to fix it?!

Answer 1

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