I read in the foundation release notes that:

...any valid (NSString *) is also a valid CFStringRef, and vice versa
but when I use the following code:

[protocolNameTextField setStringValue: theCFStringRef];
PB gives me the following warning:
Classes/Controller.m:99: warning: passing arg 1 of `setStringValue:' from incompatible pointer type
The app compiles and runs properly however - should I worry about this?

The compiler doesn't know anything about CoreFoundation's features. Use <font face = "courier">(NSString*)theCFStringRef</font> to get rid of the warning.
