Sure, but it’s bridged with NSString. The “Using Swift With Cocoa” book says: “Swift automatically bridges between the String type and the NSString class. This means that anywhere you use an NSString object, you can use a Swift String type instead … you should almost never need to use the NSString class directly in your own code.”

-cStringUsingEncoding: and several other NSString methods I’ve tried work without the “as NSString” trick; what’s special about “UTF8String”?
