Expected ',' separator : weird error

Hi,

I'm stuck, my Xcode wants me to add extra ',' after 'location:' 'response:' and 'error:' It says : "Fix It Insert ',' "

    let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL!,
        completionHandler: { (
            location: <#NSURL!#>,
            response: <#NSURLResponse!#>,
            error: <#NSError!#>) -> Void in
        println(response)
        })

Of course that would not make sens to have this : location:, <#NSURL!#>, response:, <#NSURLResponse!#>, error:, <#NSError!#>

and if I still do so, the message is still the same "Expected ',' separator" if I simply follow the advices, I have 2 comas after each parameter : location:,,

and the message become "Unexpected separator ',' Fix It Delete ',' " I see no solution to this problem ... Can somebody help me ? Thanks a lot

Yea xcode is doing this sometimes also with ";". Mostly I just ignore it and rework my code. I think you should delete those hashtags and <>. It worked 4 me

I have deleted the NSURL! automatically provided by XCode and typed again "NSURL!" , and did as well for the 2 other parameters and now there is no more errors. Thanks for the advice Jiri !

PS : the <# #> where automatically added when I copied-pasted my code into this message. I have not added them on my own.
