Thanks to TollFreeBridging a CFStringRef is equivalent to an NSString* 

// Casting a CFStringRef to an NSString object:
CFStringRef cfString;
NSString *nsString = (NSString*)cfString;

// Casting an NSString object pointer to a CFStringRef:
NSString *nsString;
CFStringRef cfString = (CFStringRef)nsString;

But don't forget to call CFRelease? on CFStringRef'''s created using CoreFoundation methods when you're done with it! eg. CFStringCreate?(...) An example is when converting PascalString?'s to NSString's, as only CoreFoundation methods exist to do so.
