I agree more with the parent on this one. I would actually expect GCD to receive first class language features before regex. There are certain operations like @sync that made their way into objective-c and Swift can use some language features to implement very common patterns in iOS/OS X programming. Then again, in Swift you can declare your own operator and call into NSRegularExpression.
