If you want to do the same thing in swift, you can use an extension.

extension NSURL {
    func queryDictionary() -> [String:String] {
        let components = self.query?.componentsSeparatedByString("&")
        var dictionary = [String:String]()

        for pairs in components ?? [] {
            let pair = pairs.componentsSeparatedByString("=")
            if pair.count == 2 {
                dictionary[pair[0]] = pair[1]
            }
        }

        return dictionary
    }
}
