How to implement SwiftyJSON to get this data - ios

Question

I've been getting into Swift and I have seen SwiftyJSON is a good library to parse JSON, but still don't know how to use it properly. I need to use SwiftyJSON to get te value of id of every user from this JSON and save them into an array:
{
"users": [
{
"id": 2960784075,

Could anybody help me to learn how could I do it ?
Thank you very much!

Answer 1

You can parse json like this way.
var IDs: [String] = []
//json is object where users are available
let users = json["users"].arrayValue
users.forEach( {
IDs.append($0["id"].stringValue)
})
print(IDs)

Answer 2

Try this code
let json = "{ \"users\": [{ \"id\": 2960784075, \"id_str\": \"2960784075\" }, { \"id\": 2959453074, \"id_str\": \"2959453074\" } ] }";
if let data = json.data(using: String.Encoding.utf8) {
let json = JSON(data: data)
for item in json["users"].arrayValue {
print(item["id"].stringValue)
}
}
Hope it helps!
