Map JSON to the model irrespective of Array or Object - ObjectMapper

I am having trouble in mapping the JSON to my object class. Here is my Model Object

class CityObject : NSObject, Mappable{
var id : String?
var name : String?

required init?(map: Map) {
}

func mapping(map: Map) {
    id <- map["id"]
    name <- map["name"]
}
}

The JSON response I get from server sometime may be Array or an Object like this.

Array:

{
"cities": [
{
  "id": "190",
  "name": "Elurupadu"
},
{
  "id": "1230",
  "name": "Sendhwa"
},
{
  "id": "1262",
  "name": "Multai"
},
{
  "id": "1480",
  "name": "Kherwara"
}]
}

Sometimes I get like this,

{
"cities": {"id": "6","name": "Hyderabad"}
}

Instead of an JSONArray it gives me JSONObject.

I am mapping to my class like this,

let list = Mapper<CityObject>().mapArray(JSONObject:cities["cities"])

This works perfectly when I get JSONArray, but the same doesn't work when I get JSONObject.

How to handle both with ObjectMapper?

As per Paulw11 suggestion down casting to MAP worked for me.

if let list = Mapper<CityObject>().mapArray(JSONObject:cities["cities"]){
   //Handles JSONArray response
}
else if let list = Mapper<CityObject>().map(JSONObject: cities["cities"]){
  //Handles JSONObject response
}
else{
  //Handles error
}
