Command-Click shows the Swift representation of Objective-C API in Xcode.
I understand that Darwin overlay which defines the Foundation APIs is here:
Also, there is: https://github.com/apple/swift/blob/master/apinotes/Foundation.apinotes that has information on the API naming.
But, I observe that the API information on both these locations are not complete. For example: API information for URLSession, HTTPCookieStorage, Bundle etc., is not found.
Could someone point me to the files from where the API information is picked up for these files?
