How to access class data as if it were a dictionary

I am making my own class which stores information to do with a user. Just like the swiftyJSON framework, I would like to accsess the data as if the variable was a dictionary.

Example,

When using SwiftyJSON, you can run code as shown below:

let x = JSON["x"]
let y = JSON["y"].strVal
let x = JSON["z"].intVal

What I would loke to do is to have a class like the following below:

class User
{
    private (set) public var DATA:[String:Any]
    public init(){}
    public function login(username:String, password:String)
    {
        //Login code here
        self.DATA = loginResult
    }
}

let user = User()
user.login(username:"username", password:"password")
let name = user["name"].strVal

How would I be able to write this in swift?

You want to use a subscript:

class User
{
    private (set) public var DATA:[String:Any]
    public init(){}
    public function login(username:String, password:String)
    {
        //Login code here
        self.DATA = loginResult
    }

    subscript(key: String) -> Any? {
        return DATA[key]
    }
}

let user = User()
user.login(username:"username", password:"password")
let name = user["name"].strVal

You probably want to store DATA as SwiftyJSON, so you can call strVal, etc. on it - just update the backing property and subscript signature as needed.
