If you want to get the results to do anything useful, then you need to implement the completionHandler.

Also, if you want to access the URL (from the urlRequest) and obtain the results of a GET request, then you need to add task.resume().

I hope the following example helps: 

let urlRequest = URLRequest(url: url)
let session = URLSession.shared
let task = session.dataTask(with: urlRequest, completionHandler:{ (data: Data?, response: URLResponse?, error: Error?) in
    if let response = response {
        print(response)
    }
    if let error = error { 
        print(error)
    }   
}) 
    task.resume()
