Answer 1

Swift 2-4

Another solution, using Extension

extension JSON{
    mutating func appendIfArray(json:JSON){
        if var arr = self.array{
            arr.append(json)
            self = JSON(arr);
        }
    }
    
    mutating func appendIfDictionary(key:String,json:JSON){
        if var dict = self.dictionary{
            dict[key] = json;
            self = JSON(dict);
        }
    }
}

Use:

var myJSON: JSON = [
    "myDictionary": [String:AnyObject](),
    "myArray" : [1,2,3,4]
]

myJSON["myDictionary"].appendIfDictionary(key:"A", json: JSON(["key1":"value1"]))
myJSON["myDictionary"].appendIfDictionary(key: "B", json: JSON(["key2":"value2"]))
myJSON["myArray"].appendIfArray(json: JSON(5))

print:

{
  "myArray" : [
    1,
    2,
    3,
    4,
    5
  ],
  "myDictionary" : {
    "B" : {
      "key2" : "value2"
    },
    "A" : {
      "key1" : "value1"
    }
  }
}
