AHA!
I couldn't find out how to add it through the Build Settings, (thanks terrible UI!), but If you want this in your project and your project has a .pch file, you can turn on the warning through a pragma and a clang diagnostic push by adding the code below to your .project wide header file.
/ AZ @@ 06030215 - Enable warnings on build for private interface variables manually declared in the @interface.
# pragma clang diagnostic push
# pragma clang diagnostic warning "-Wobjc-interface-ivars"
Thanks to Matt Thompson for his pragma article and the Clang docs.

Hope this is of use to some of you too.
