What's wrong?

I'm pretty sure I've done this correctly. Maybe I'm missing something. There's no errors in the editor, and this kind of thing is happening way to often on Treehouse lately, it's getting a little annoying.

Can someone help please?

import Foundation

// Add your code below
typealias BlogPostCompletion = (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void

func fetchTreehouseBlogPosts(completion: BlogPostCompletion) {

I've figured it out, it's another weird syntax problem that isn't wrong, but treehouse doesn't like it for whatever reason, I just used this instead:

func fetchTreehouseBlogPosts(completion: ((NSData!, NSURLResponse!, NSError!) -> Void))
