One toll free bridged object is NSString.

NSString is a class cluster. By design, you don't know what it will return as a created instance. Is there a design specification (is it documented) that says everything it returns is toll-free with CFString, or just NSCString hidden class?

When we say it's toll-free bridged, we mean that any NSString can be treated as a CFString, and vice versa.
