How can I get the value of [approved_user"][" id "] with swifty json?

Solution

First, I hope you have json in SwiftyJson format JSON

let json = JSON(data)

Ok, so first you have to get array for key "result"

json["result"]

then we need some element from this array, so we have to specify index of it

json["result"][0]

then we need object for key "approved_user"

json["result"][0]["approved_user"]

and now we can get its id property

json["result"][0]["approved_user"]["id"]

So:

let id = json["result"][0]["approved_user"]["id"].intValue

Anyway, I would suggest you to start using Swift 4+, since you can learn with Codable and then your iOS programming life will be much easier. ;)
