//URLSessionTaskDelegate
//You use this protocol in one of two ways, depending on how you use a URLSession:
//If you create tasks with Swift’s async-await syntax, using methods like bytes(for:delegate:) and data(for:delegate:), you pass a delegate argument of this type. The delegate receives callbacks for things like task progress, while the call point awaits the completion of the task. A delegate that receives life cycle and authentication challenge callbacks as the transfer progresses.
//If you add tasks to the session with methods like dataTask(with:) and downloadTask(with:), then you implement this protocol’s methods in a delegate you set on the session. This session delegate may also implement other protocols as appropriate, like URLSessionDownloadDelegate and URLSessionDataDelegate. You can also assign a delegate of this type directly to the task to intercept callbacks before the task deliver
