Xcode 7.0 build error

I’m trying to run a build in Xcode 7 from unity 5.2. I got it working with an empty test project but with my other project it halt on the following error:

Undefined symbols for architecture arm64:
“__GetUsersCountryLocale”, referenced from:
_RegionLocale__GetUsersCountryLocale_m2 in Bulk_Assembly-CSharp-firstpass_0.o
(maybe you meant: _RegionLocale__GetUsersCountryLocale_m2)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea what causes it / how to fix this this?
Thanks in advance. Ric

This error is related to the BrainCloud plugin. It is due to the fact that you’re missing the RegionLocaleNative.mm file in your Plugins - IOS folder in your Unity project.
