Get string from JSON Array in Swift

I need to get string from the JSON Array which is a response from the external server. This is my code: 

if let dictionary = NSJSONSerialization.JSONObjectWithData(data,options: NSJSONReadingOptions.MutableContainers,error: &parsingError) as NSDictionary?{

    var info : NSArray = dictionary.valueForKey("data") as NSArray
    var names: String? = info[0].valueForKey("firstname") as? String

    println("name ++\(names)")

}

It's compiling but when I execute, not running I got as

thread 8:exc_bad_access (code=2 ..

This is Dictonary coming from server side

{
 data =     {
     Id = 55;
     firstName = fgg;
     gender = 1;
 };
 success = 1; }

I followed thread without success : Getting Values from JSON Array in Swift

Can anyone help me to get this string out? I cannot find out the error I have done here. Any help would be appreciated.

Try this 

if let dictionary = NSJSONSerialization.JSONObjectWithData(data,options: NSJSONReadingOptions.MutableContainers,error: &parsingError) as NSDictionary?{

    var info : NSDictionary = dictionary.valueForKey("data") as! NSDictionary 
    var names: String? = info["firstName"] as? String 
    println("name ++\(names!)")

}

Try this : 

do
{
 let data = try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted)
}
catch _{}

let data      = json["data"] as! NSDictionary
let firstName = data["firstName"]

let dataId = response.value(forKeyPath: "data.id") as! NSNumber

I usually do this if am not up to deserialization.
