why does this garbage data come with the output?

I have written this program to fetch data as NSArray in ios swift. Why am I getting so much garbage value below in the output besides the required data? 

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    data = dataOfJson("http://192.168.1.8:8888/service.php")
    println(data)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    //Dispose of any resources that can be recreated.
}

func dataOfJson(url: String) -> NSArray {

    var urla = NSURL(string: url)
    var data:NSData = NSData(contentsOfURL: urla!)!

    println(data)
    return (NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as! NSArray)
}

Output:

The "extra" logging is there because you logged it here:

func dataOfJson(url: String) -> NSArray {

    var urla = NSURL(string: url)
    var data:NSData = NSData(contentsOfURL: urla!)!

    println(data) // This is printing the hex you're seeing...
    ...
}

You're just seeing the binary data of the response. You could convert it into a string, in which case you'd see the raw (unparsed) JSON (which is slightly different to the output for the parsed one - the raw JSON makes it clear that it's actually an array, and the first object starts with the "Name" property, not "Address")... but unless you actually want it, I'd just get rid of the println call.
