Objective-C Enums

Enumerators are a great way of defining predefined constant variables that can be passed around into methods between classes. Objective-C has a macro called NS_ENUM that makes it very easy to create integer based enumerators that work in C as well as Swift.

I'm from Swift to learn OC, could I use NSString for enum type, like say I would like to store some namespace in enum.
