You can use JSONSerialization class for this purpose. Please see the code snippet below cooked up in Playground

import Foundation

// Dictionary containing data as provided in your question.
var dictonary : [String : Any] = ["question":"If you want to create a custom class which can be displayed on the view, you can subclass UIView.",
                                  "answers":["True", "False"],
                                  "correctIndex":0,
                                  "module":3,
                                  "lesson":0,
                                  "feedback":"Subclassing UIView gives your class the methods and properties of a basic view which can be placed onto the view."
                                 ]


if let jsonData = try JSONSerialization.data(withJSONObject: dictonary, options: .init(rawValue: 0)) as? Data
{
    // Check if everything went well
    print(NSString(data: jsonData, encoding: 1)!)

    // Do something cool with the new JSON data
}

If you run this code in Xcode playground, you can see your data printed in JSON format Once you have the JSON , you can use the networking library of your choice to send the data over to the server.
