Not sure what I'm missing here.

This chunk of code is giving me a hard time.

class NetworkOperation {

lazy var config: NSURLSessionConfiguration = NSURLSessionConfiguration.defaultSessionConfiguration()

lazy var session: NSURLSession = NSURLSession(configuration: self.config)

let queryURL = NSURL

typealias JSONDictionary = ([String: AnyObject]?) -> Void

init(url: NSURL){
    self.queryURL = url
}

Why is Xcode wanting me to put parenthesis after "let queryURL = NSURL"?

And even when I do that, I'm getting the error, "Cannot assign to 'querryURL' in 'self'"

I believe you meant to write let queryURL : NSURL.
