How to parse JSON in Swift 2? - json

Question

I have a PHP web api that returns json in the following format:
{"users":[
{"user": {id:"1","name":"ahmad"}},
...
]}
In my Swift 2 code, I am able to retrieve the data above store it in an NSArray named users
Now, I need to iterate throw each user to convert it into an object:
for user in users {
print("found: \(user)")
}
That ouputs something like:
found: {
user = {
id = 1;
name = ahmad;
};
}
but when I try to access any element of that object I get an error:
let id = user["user"]["id"] //does not work: Xcode wont compile
let id2 = user["user"]!["id"]! //does not work: Xcode wont compile
let id3 = user!["user"]!["id"]! //does not work: Xcode wont compile
Then I tried :
if let u=user["user"] { //does not work: Xcode wont compile
// do somthing
}
I put a break point at print("\(user)") to see what is going on, and here is what I found:
When I print the description of each individual user I get:
How can I access the elements of this JSON data in Swift 2?

A NSArray only holds AnyObject so you have to cast it (to Array<Dictionary<String, Dictionary<String, String>>>. Below you see the shorthand):
// this is a forced cast and you probably get runtime errors if users cannot be casted
for user in users as! [[String : [String : String]]] {
print("found: \(user)")
}
