Deserialize JSON / NSDictionary to Swift objects

Question

Is there a way to properly deserialize a JSON response to Swift objects resp. using DTOs as containers for fixed JSON APIs?

You do this by using NSJSONSerialization. Where data is your JSON.

First wrap it in an if statement to provide some error handling capablity

if let data = data,
 json = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String: AnyObject] {
// Do stuff
} else {
  // Do stuff
  print("No Data :/")
}

then assign them:

let email = json["email"] as? String
let name = json["name"] as? String
let password = json["password"] as? String

Now, This will show you the result:

print("Found User iname: \(name) with email: \(email) and pass \(password)")

Taken from this Swift Parse JSON tutorial. You should check out the tutorial as it goes a lot more in depth and covers better error handling.
