12,890 PointsClosure Syntax doesn't work
I've tried some options to write the closure but can't figure out what's wrong. My code:
typealias BlogPostCompletion = (data:NSData!, response:NSURLResponse!, error:NSError!) -> Void
func fetchTreehouseBlogPosts(completion:BlogPostCompletion) { }
Anyone can help? Thank you

I notice that your typealias definition is incorrect. It should look like this without the parameter names:
typealias BlogPostCompletion = ((NSData!, NSURLResponse!, NSError!) -> Void) //The outer parenthesis are only required for the challenge.
Hopefully this helps.
