Get key of dictionary on JSON parse with SwiftyJSON - ios

Question

I want to get "key of dictionary" (that's what I called, not sure if it is right name) on this JSON
{
"People": {
"People with nice hair": {
"name": "Peter John",
"age": 12,
"books": [
{
"title": "Breaking Bad",
"release": "2011"
},
{
"title": "Twilight",
"release": "2012"
},
{
"title": "Gone Wild",
"release": "2013"
}
]
},
"People with jacket": {
"name": "Jason Bourne",
"age": 15,
"books": [
{
"title": "Breaking Bad",
"release": "2011"
},
{
"title": "Twilight",
"release": "2012"
},
{
"title": "Gone Wild",
"release": "2013"
}
]
}
}
}
First of all, I already created my People struct that will be used to map from those JSON.
Here is my people struct
struct People {
var peopleLooks:String?
var name:String?
var books = [Book]()
}
And here is my Book struct
struct Book {
var title:String?
var release:String?
}
From that JSON, I created engine with Alamofire and SwiftyJSON that will be called in my controller via completion handler
Alamofire.request(request).responseJSON { response in
if response.result.error == nil {
let json = JSON(response.result.value!)
success(json)
}
}
And here is what I do in my controller
Engine.instance.getPeople(request, success:(JSON?)->void),
success:{ (json) in
// getting all the json object
let jsonRecieve = JSON((json?.dictionaryObject)!)
// get list of people
let peoples = jsonRecieve["People"]
// from here, we try to map people into our struct that I don't know how.
}
My question is, how to map my peoples from jsonRecieve["People"] into my struct?
I want "People with nice hair" as a value of peopleLooks on my People struct. I thought "People with nice hair" is kind of key of dictionary or something, but I don't know how to get that.
Any help would be appreciated. Thank you!

Answer 1

While you iterate through dictionaries, for instance
for peeps in peoples
You can access key with
peeps.0
and value with
peeps.1

Answer 2

You can use key, value loop.
for (key,subJson):(String, JSON) in json["People"] {
// you can use key and subJson here.
}
