I'm trying to buid on XCode 10.1 my project done in Unity 2018.2.20f1, Vuforia: 7.5.26 and I'm getting this error:
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_MFMailComposeViewController", referenced from:
objc-class-ref in ISN_SocialGate.o
"_OBJC_CLASS_$_MFMessageComposeViewController", referenced from:
objc-class-ref in ISN_SocialGate.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How can we fix it?
Best Regards,
Fabio
