how to send nested json as request param in swift?

Question

My backend expects the following json for login.

{
"userName": "username",
"password" : "password",
"deviceInfoObj": {
"uniqueId":"q33qq3wr3wrw",
"model" : "6S"
}
}

Here is what I have

let deviceInfoObj: [String : String] = [
                    "uniqueId": "4d600df2c7e7c55",
                    "model": "6S"
            ]

let loginParams: [String:String] = [
                "userName": String(uname) ,
                "password" : String(pwd),
                "deviceInfo": deviceInfoObj

Here is how I make the request.

engine.sendRequestWithParms(loginParams, serviceUrl: NSURL(string: urlString)).

I get build error:

cannot-convert-value-of-type-string-string-to-expected-argument-type-string

try this:

let loginParams: [String: AnyObject] = [
  "userName": String(uname) ,
  "password" : String(pwd),
  "deviceInfo": deviceInfoObj
]

should that be "let deviceInfoObj" or "let loginParams"?
