realm-swift: "visibility settings" error in core when building via CocoaPods

Hi Guys,

After updating to Realm 2.3.0 (was 2.1.2), I get the following warning in Xcode:

direct access in function 'realm::SharedGroup::SharedGroup(realm::Replication&, realm::SharedGroupOptions)' from file '/Users/xxxx/Documents/Projects/ImageScape/Pods/Realm/core/librealm-ios.a(client_file_access_cache-iphonesimulator.o)' to global weak symbol 'realm::util::InterprocessMutex::initialize_statics()' from file '/Users/xxxx/Library/Developer/Xcode/DerivedData/ImageScape-hetxuiirverpbbdrqeqlutdnufdo/Build/Products/Debug-iphonesimulator/Realm/libRealm.a(shared_realm.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.

As far as I can check everything works as expected, but the warning isn’t nice of course. Thanks!
