Use Alomofire for get data from server in Xcode 9 - json

Question

I'm beginner in iOS programming but I work in android so now I stuck in a problem in iOS.
I know my question is general but I really need your help!
in android for connect to server we do like below:
Call<String> myList = service.Contact_List("");
myList.enqueue(new Callback<String>() {
#Override
public void onResponse(Call<String> call, Response<String> response) {
try{
ArrayList<Contact> contactArrayList = new ArrayList<>();
JSONArray jsonArray = new JSONArray(response.body());
for(int i=0 ; i<jsonArray.length() ; i++)
contactArrayList.add(gson.fromJson(jsonArray.getJSONObject(i).toString(), Contact.class));
}catch (Exception e) {
Log.d("Catch","Error")
}finally {
}
}
#Override
public void onFailure(Call<String> call, Throwable t) {
Log.d("Failure","Error")
}
});
and in xcode I do like below :
let url = URL(string: "http://api.example.com/Contact-List")
Alamofire.request(url!, method: HTTPMethod.post, parameters: param, encoding: URLEncoding.default, headers: nil).responseJSON { (response) in
print("response.request")
print(response.request as Any) // original URL request
print("response.response")
print(response.response as Any) // URL response
print("response.result.value")
}
and my result is something like this:
[{"Id":1,"Name":"Mary","TelNumber":"09111111"},{"Id":2,"Name":"Sarah","TelNumber":"09222222"},
{"Id":3,"Name":"Ben","TelNumber":"09333333"}]
now my question is that how can I do like this code in Xcode(swift 3 ):
for(int i=0 ; i<jsonArray.length() ; i++)
contactArrayList.add(gson.fromJson(jsonArray.getJSONObject(i).toString(), Contact.class));
in addition, I use ASP.net in server side.
I am really sorry about my long and ambiguous question!
thanks for any suggestions.

First create NSObject swift file :
then add code
class demo {
var ID: String
var Name: String
init(ID: String, Name: String) {
self.ID = ID
self.Name = Name
}
}
Try like this way :
let data = response.result.value
if data != nil {
self.presentWindow.hideToastActivity()
if let response = data as? [[String: AnyObject]] {
for detail_data in response {
let Id = detail_data["Id"] as? String ?? ""
let Name = detail_data["Name"] as? String ?? ""
let demoObj = demo(ID: ID, Name: Name
self.demoObjects.append(demoObj)
}
}
}

for converting string response to JSON
Sample code will be something like this. Don't forget to handle unwrap stuff
let data1 = "[{\"Id\": 1,\"Name\": \"Mary\",\"TelNumber\": \"09111111\"},{\"Id\": 2,\"Name\": \"Sarah\",\"TelNumber\": \"09222222\"}]" //your JSON From API Response
let data = data1.data(using: .utf8)
do {
let array = try JSONSerialization.jsonObject(with: data!) as! [[String : Any]]
for detail_data in array {
let Id = detail_data["Id"] as? Int ?? 00
let Name = detail_data["Name"] as? String ?? ""
print("Id:",Id)
print("Name:",Name)
print("****")
}
} catch {
print("Exception occured \(error))")
}
