JSON_encode for ALAMOFIRE - json

Question

I have a very simple Swift code to retrieve JSON data. But somehow it doesn't work properly.
Alamofire.request("*URL*").validate().responseJSON { response in
print(response.result.value)
if response.result.isSuccess {
if let userList:[[String:Any]] = response.result.value as? [[String:Any]] {
for user:[String:Any] in userList {
if let userName = user["name"] as? String {
self._myList.append(User(name: userName, value: true))
}
}
}
self.tableView.reloadData()
} else {
print(response.result.error)
}
}
During the execution, I get this error message in the console :
Optional(Alamofire.AFError.responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.})))
The print after calling Alamofire.request is showing "nil" in the console.
What I don't understand is it's working if I use .responseString instead of .responseJSON (but it shows only a String). I really need to use .responseJSON as I need to parse the result.
My JSON that appears on the web browser is very simple as well :
[{"name":"MrX","value":"0"}]
Any idea ?

use this
import Alamofire
import SwiftyJSON
let baseURL: String = "http://baseURL.com"
Alamofire.request(baseURL)
.responseJSON { response in
guard response.result.error == nil else {
// got an error in getting the data, need to handle it
print("error calling GET")
print(response.result.error!)
return
}
if let value = response.result.value {
let json = JSON(value) // JSON comes from SwiftyJSON
print(json) // to see the JSON response
let userName = json["name"].array // .array comes from SwiftyJSON
for items in userName! {
self._myList.append(User(name: items, value: true))
}
DispatchQueue.main.async {
self.tableView?.reloadData()
}
}
}
and take the .validate() out, if you take that out you will see more detailed error description. Hope that helps.
