Suppose that we have a code statement that is dependent on another code statement, as shown in the following code:
func sendRequest() { let sessionConfig = URLSessionConfiguration.default let session = URLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil) var url: URL? var request: URLRequest /* First request block starts: */ url = URL(string: "https://httpbin.org/get") request = URLRequest(url: url! as URL) request.httpMethod = "GET" let task = session.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) -> Void in if (error == nil) { let statusCode = (response as! HTTPURLResponse).statusCode print("URL Session Task Succeeded: HTTP \(statusCode)") ...
