4,464 PointsDespite having no compiler error, I do not manage to configure the completion handler. Can someone help?
I have been trying multiple combinations and re-use several existing piece of code, but for some reason I keep getting the same error Message: "Make sure you pass the correct order and type of parameters to the completion handler of the fetchTreehouseBlogPosts method."
import Foundation
// Add your code below
typealias BlogPostCompletion = ((NSData!, NSURLResponse!, NSError!) -> Void)
func fetchTreehouseBlogPosts(handler: BlogPostCompletion){
let blogURL = NSURL(string: "http://blog.teamtreehouse.com/api/")
let requestURL = NSURL(string: "get_recent_summary/?count=20", relativeToURL: blogURL)
let request = NSURLRequest(URL: requestURL!)
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)
//Add your code between the comments
let dataTask = session.dataTaskWithRequest(request){
(let data, let response, let error) in
handler(data, response, error)
}
//Add code above
dataTask.resume()
}
