I am getting below error after pod update in Google VR Sdk
Undefined symbols for architecture x86_64:
"_clock_gettime_nsec_np", referenced from:
base::GetCurrentTimeNanos() in libGVRSDK.a(get_current_time.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I was using Xcode 7.3, when I switched to Xcode 8 and above version, issue is resolved.
