Foundation is more inclusive than ObjectiveC. I'm not sure, however, if Foundation is a superset (if you will) of ObjectiveC. I.e., ObjectiveC might include things not included by Foundation.

Anyway, if, e.g., you're just subclassing from NSObject, you can just import ObjectiveC.NSObject instead of import Foundation.NSObject, which also works but includes more than needed.

If, however, e.g., you're declaring a property of type NSDate, import ObjectiveC.NSDate doesn't work, so you'll have to import Foundation.NSDate.
