Unable to parse in swift 2

[speedoholic]

I tried to parse this JSON using the following swift code but failed:

let jsonData = NSData(contentsOfFile: NSBundle.mainBundle().pathForResource("provinces", ofType: "json")!)
        if jsonData != nil {
            let json = try? NSJSONSerialization.JSONObjectWithData(jsonData!, options:NSJSONReadingOptions.AllowFragments)
            let array: Array<Dictionary<String, String>>? = json as? Array<Dictionary<String, String>>
            if array != nil {
                for dic in array! {
                     //never reaches here
                }
            } else {
                //always reaches here
                print("found nil array for province json")
            }

Since the same code is working for other JSON files, I assume there is some syntax error with respect to Swift.
