Resolve C++ namespace collision when building Google Protobuf 2.5.0 with Xcode 5.0 for iOS 7.0 Apple includes a copy of protobuf as a private framework and if you link a locally built copy into and app that already uses the private framework version it will result in application crashes. Thanks Apple!
