Oh! I think I figured out what I'm doing wrong. The typealias doesn't understand local names, and that makes some sense. I can just get rid of those altogether and be find. Sorry for the noise.
----------------
One of the things I dislike the most about Swift is its insistence on "being expressive". The docs talk about "allowing" expressivity, but should you choose to allow it, you then require it, and Swift implicitly requires it in a lot of places.
Here's an example in a playground, where the call to inSendRequest() angers the compiler:
import Cocoa
typealias HTTPHeaders = [NSObject : AnyObject];
typealias ResponseTuple = (NSData?, HTTPHeaders?);
typealias SendResponseFunc = (inResp: NSData?, inRespHeaders: HTTPHeaders?) -> ();
func
waitForSweep(inSendResponse: SendResponseFunc)
{
inSendResponse(nil, nil); // Missing argument labels 'inResp:inRespHeaders'
}
I find this "expressiveness" to be overly verbose.
Somewhere I read that setting the external name to "_" suppressed this, but I'm not able to set external names in tuples, which is what the SendResponseFunc typealias is.
Any way to get what I want?
TIA,
