I dunno, really. Support for CF things (and C things and unmanaged pointers)
seems to vary release by release, so I don’t try to keep up.
Bridging is consistent, though, I believe. It’s very specific:
Int,etc <-> NSNumber
String <-> NSString
[AnyObject] <-> NSArray
[NSObject: AnyObject] <-> NSDictionary
But this doesn’t extend to things we know about Obj-C and Cocoa externally to
Swift, or internally about the implementations (such as toll-free bridging
between CF and NS types). Remember, too, that we had to cast CFString variables
like kSecReturnData to NSString manually in Obj-C to shut the compiler up.
P.S. In my earlier example, ‘as String’ seems to work as well as ‘as NSString’.
I presume that’s because of bridging, once you’ve got as far as NSString.
