尝试这种方式：

let sessionConfig = URLSessionConfiguration.default

        // Create session, and optionally set a URLSessionDelegate
        let session = URLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)

        // Create request
        guard let URL = URL(string: "YOUR_URL_HERE") else { return }
        let request = URLRequest(url: URL)

        let task = session.dataTask(with: request) { (data, response, err) in
            if (err == nil) {
                // Success
                let statusCode = (response as! HTTPURLResponse).statusCode
                print("URL Session Task Succeeded: HTTP \(statusCode)")
                if let data = data {

                    do {
                        let jsonResult = try JSONSerialization.jsonObject(with: data, options: .mutableContainers)

                        // Parse JSON data
                        if let json = jsonResult as? [String:Any],
                        let dataArr = json["Data"] as? [[String:Any]] {

                            for item in dataArr {

                                let name = item["name"] as! String
                                // AND SO ON PARSE ANOTHER FIELDS
                            }
                        }

                    } catch let err {
                        print(err)
                    }

                }
            } else {
                // Failure
                print("URL Session Task Failed: \(err!.localizedDescription)")
            }
        }
        task.resume()
        session.finishTasksAndInvalidate()

let result = (response as! NSDictionary).object(forKey: "response") as! NSDictionary
let data = result.object(forKey: "Data") as! NSArray
for int i in array.count - 1 {
let dict = data[i] as! NSDictionary
let name  = dict.value(forKey: "name") as! String
let location = dict.value(forKey: "location") as! NSArray
let dictLocation = location[0] as! NSDictionary
let city = dictLocation.value(forKey: "city") as! String
}
