Unable to use SwiftyJSON to access JSON data - json

Question

I'm trying to access some JSON data but I can't access that using swiftyJSON. I'm getting JSON response back so I'm acquiring it using alamofire. Here's the JSON:
{"groupID":"6","groupName":"Test","teacher":"teacher1
","teacherID":"13","Locations":
[{"locationID":"5","locationName":"field"},
{"locationID":"6","locationName":"34th"}],"Error":""}
I'm using print statements to debug what's wrong. Here's the code that I'm trying to use:
let json = JSON(response.result.value ?? "error")
//let jsonError = json["Error"]
print("=================<JSON RESPONSE>=================");
print(json)
print("=================</JSON RESPONSE/>=================");
self.groupID = json["groupID"].stringValue
self.groupName = json["groupName"].stringValue
self.teacherID = json["teacherID"].stringValue
let locjson = json["Locations"]
print("Entering LocJSON Loop")
print("=================<LOCJSON >=================");
print("GNAME:" + self.groupID)
print("TID: " + json["teacherID"].stringValue)
print("Locjson.stringalue: " + locjson.stringValue)
//print("LocationJSON" + json["Locations"]);
print("=================</LOCJSON/>=================");
for (key, object) in locjson {
print("In LocJSON Loop")
let locationIDVar: Int? = Int(key)
self.locations[locationIDVar!].locationID = locationIDVar!
self.locations[locationIDVar!].locationName = object.stringValue
print(self.locations[locationIDVar!].locationName)
print(object);
}
Here's the output from console that corresponds to the print statements.
=================<JSON RESPONSE>=================
{"groupID":"6","groupName":"Test","teacher":"Teacher1"
,"teacherID":"13","Locations":
[{"locationID":"5","locationName":"field"},
{"locationID":"6","locationName":"34th"}],"Error":""}
=================</JSON RESPONSE/>=================
Entering LocJSON Loop
=================<LOCJSON >=================
GNAME:
TID:
Locjson.stringalue:
=================</LOCJSON/>=================
Also, how do I get to the multiple locations that are inside 'Locations'?

Answer 1

The value for key Locations is an array containing dictionaries.
let locjson = json["Locations"].arrayValue
for location in locjson {
let locID = location["locationID"].stringValue
let locName = location["locationName"].stringValue
print(locID, locName)
}
In Swift 4 I'd prefer Decodable over SwiftyJSON because you can directly decode into structs.
