Converting DataResponse<String> to a usable type

I have a POST request that is illustrated below. I need some help on how to be able to use the response data. The response I am getting is in a form of a dictionary. What is the best practice to use here? The error message I am getting is:

Cannot assign value of type 'DataResponse' to type 'String'

func getRequest(){
    let urlString = "http://scissors.pythonanywhere.com/getRequest"
    Alamofire.request(urlString, method: .post, parameters: ["date": self.weekDays[self.itemSelectedIndex]],encoding: JSONEncoding.default, headers: nil).responseString {
        response in
        switch response.result {
        case .success:
            print(response)
            var backToString = String(data: response, encoding: String.Encoding.utf8) as String?

            break
        case .failure(let error):

            print(error)
        }
    }
}

I tried self.bookings = response as! String but it gives me a warning saying it will fail. Also tried this: Alamofire in Swift: converting response data in usable JSON dictionary with no luck.

EDIT

This is the print i get from response.

SUCCESS: {
    "10:00" =     {
        booked = false;
        name = "";
        number = "";
    };
    "10:30" =     {
        booked = false;
        name = "";
        number = "";
    };
    "11:00" =     {
        booked = false;
        name = "";
        number = "";
    };
}

I actually ended up using this method which was very simple and easy. In my case bookings was declared like this: var bookings: NSDictionary = [:]

func getRequest(){

    let urlString = "http://scissors.pythonanywhere.com/getRequest"
    Alamofire.request(urlString, method: .post, parameters: ["date": self.weekDays[self.itemSelectedIndex]],encoding: JSONEncoding.default, headers: nil).responseJSON {
        response in
        switch response.result {
        case .success(let JSON):
            self.bookings = JSON as! NSDictionary

            self.tableView.reloadData()

            break
        case .failure(let error):
            print(error)
        }
    }
}

Now that you have the JSON representation, you should be able to do something like this:

if let dict = response as? [String:Any]{
    if let obj = dict["10:00"] as? [String:Any]{
         let booked = obj["booked"] as? Bool ?? false
         print("booked: \(booked)");
    }
}
