xcode swift 3.0 parse JSON response - ios

Question

I'm trying to get the status code and put it in an if statement. This code will run in the xCode playground.
Right now status returns as ["200"] with square brackets around it. If I remove the brackets it returns as nil.
How to I return status as 200 and put it in an if statement?
import Foundation
let str = "{\"names\": [\"Bob\", \"Tim\", \"Tina\"],\"status\"[\"200\"],\"message\":\"User has been created\",\"id\":null,\"username\":\"asdf\"}"//"{\"names\": [\"Bob\", \"Tim\", \"Tina\"]}"
let data = str.data(using: String.Encoding.utf8, allowLossyConversion: false)!
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
let status = json["status"] as? [String]
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}

Answer 1

You can try this workaround:
let responseString = Optional("{\"status\":\"200\",\"message\":\"User has been created\",\"id\":null,\"username\":\"asdf\"}")
let responseData = responseString?.data(using: .utf8)
let dict: Dictionary<String, Any> = try JSONSerialization.jsonObject(with: responseData!, options: []) as! Dictionary<String, Any>
let status = dict["status"] // optional value stored with "status" key in Dictionary
It seems that actually, Swift 3 refuses to compile using:
let dict: Dictionary<String, Any> = try JSONSerialization.jsonObject(with: responseString?.data(using: .utf8)!, options: []) as! Dictionary<String, Any>
Swift 3 claims that responseString?.data(using: .utf8)! should be unwrapped although it is already.

Answer 2

let str = "{\"names\": [\"Bob\", \"Tim\", \"Tina\"],\"status\":[\"200\"],\"message\":\"User has been created\",\"id\":null,\"username\":\"asdf\"}"//"{\"names\": [\"Bob\", \"Tim\", \"Tina\"]}"
let data = str.data(using: .utf8)
do {
let json = try JSONSerialization.jsonObject(with: data!, options: []) as! [String: AnyObject]
let status = json["status"] as? [String]
let yourValue = status?[0]
} catch let error as NSError {
print("Failed to load: \(error.localizedDescription)")
}
I just add ( : ) after status in json formate to be invalid
