How to access a property list

I have created a property list with continents, countries, and random facts as shown below:

property list

I can access the top level keys from the property list easily enough:

if let path = NSBundle.mainBundle().pathForResource("countryData", ofType: "plist") {
            dict = NSDictionary(contentsOfFile: path)
        }
countries += dict!.allKeys as! [String]

If I wanted to access the second element in the vanuatu array, however, things fall apart. I would think objectForKey would get the country dictionary and then use objectForKey again to get the country array. But so far, that hasn't worked. At all...

You can get data from plist file like that. I have created a plist file for countryCodes.

func fetchCounrtyCodes() -> [CountryCodes]{
let name = "name"
let dial_code = "dial_code"
let code = "code"

var countryArray = [CountryCodes]()

guard let filePath = NSBundle.mainBundle().pathForResource("CountryList", ofType: "json") else {
    print("File doesnot exist")
    return []
}
guard let jsonData = NSData(contentsOfFile: filePath) else  {
    print("error parsing data from file")
    return []
}
do {
    guard let jsonArray = try NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.AllowFragments) as? [[String:String]] else {
        print("json doesnot confirm to expected format")
        return []
    }
    countryArray = jsonArray.map({ (object) -> CountryCodes in
        return CountryCodes(name: object[name]!, dial_code:object[dial_code]!, code: object[code]!)
    })
}
catch {
    print("error\(error)")
}
return countryArray
}

struct CountryCodes{
var name = ""
var dial_code = ""
var code = ""
}

            if let australia = dict["australia"] as? [String:AnyObject]{
                // access the second element's property here
            if let vanuatu = australia["vanuatu"] as? [String]{
                // Access the vanuatu here
                } 
            }
        }

        if let vanuatu = dict.objectForKey("australia") as? [String:AnyObject]{
            if let vanuatuArray = vanuatu["vanuatu"] as? [String]{
                print(vanuatuArray[1])
            }
        }
