Xcode 11, converted String to NSString is working for me.

func jsonToString(json: AnyObject) -> String{
    do {
        let data1 = try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted)
        let convertedString = String(data: data1, encoding: String.Encoding.utf8) as NSString? ?? ""
        debugPrint(convertedString)
        return convertedString as String
    } catch let myJSONError {
        debugPrint(myJSONError)
        return ""
    }
}
