I've been trying to integrate the Vuforia SDK into a preexisting iOS app, but I keep getting errors that seem to be related to the 64-bit architecture. Here is what I'm getting (also attached a screenshot):
Undefined symbols for architecture arm64: "_fcvV5w_1", referenced from: l6862 in libVuforia.a(libVuforia.a-arm64-master.o) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
Also, if I remove arm64 from "Valid Architectures" the app seems to compile. However, arm64 is now required so I can't do that.
