initialization of immutable value 'treehouseDownloadTask' was never used; consider replacing with assignment to '_'

i don't know way i getting this

func getRecentBlogPosts(completion: (NSURLResponse! -> Void)) {

    let treehouseDownloadTask = session.downloadTaskWithRequest(request) {
        (let url, let response, let error) in
        completion(response)
    }

}

Before the last } you have to add:

treehouseDownloadTask.resume()

Otherwise your download task will never be executed.
