Error when decoding JSON - keyNotFound(CodingKeys

Question

I am trying to parse JSON data over the network. Below you can see where the magic is happening.

func getBookingsForDate(date: String, completionHandler: @escaping ([String:String]) -> Void ){

struct bookings: Codable {

    var bookieName : String
    var bookieNumber: String
    var booked: String
    var bookingTime: String

    private enum Codingkeys: String, CodingKey{

        case bookieName
        case bookieNumber
        case booked
        case bookingTime
    }
}

let params = ["date":date]

let urlString = "http://mscissorss.pythonanywhere.com/getBookings/"
Alamofire.request(urlString, method: .get, parameters: params).responseJSON {
    response in
    switch response.result {
    case .success(let JSON):

        let decoder = JSONDecoder()
        guard let _ = response.data else{
            return
        }
        do {
            let loginDetails = try decoder.decode(bookings.self, from: response.data!)
            print(loginDetails)
        } catch let err{
            print(err)
        }

        //let bookings = JSON as! NSDictionary
        //completionHandler(JSON)
        /*
        do {
            let decoder = JSONDecoder()
            let gitData = try decoder.decode(bookings.self, from: JSON)
            print(gitData.bookieName)

        } catch let err {
            print("Err", err)
        }
        */
        break
    case .failure(let error):
        print(error)
    }
}
}

Given the code i am getting the following error message:

keyNotFound(CodingKeys(stringValue: "bookieName", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"bookieName\", intValue: nil) (\"bookieName\").", underlyingError: nil))

And the JSON response that i am getting looks like this:

{
    0 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "10:00";
    };
    1 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "10:30";
    };
    10 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "15:00";
    };
    11 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "15:30";
    };
    12 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "16:00";
    };
    13 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "16:30";
    };
    14 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "17:00";
    };
    15 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "17:30";
    };
    16 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "18:00";
    };
    2 =     {
        booked = false;
        bookieName = "";
        bookieNumber = "";
        bookingTime = "11:00";
    };
}

It is the first time i am decoding so if you have an answer please try to explain a bit to why i need to make the change that i need.

UPDATE

After changing the code to what @sh_khan and @vadian suggested it worked to parse it however i am still getting this error inside my parsed object:

["1": MagicS.(unknown context at 0x106932738).bookings(bookieName: "", bookieNumber: "", booked: "false", bookingTime: "10:30"), 
"0": MagicS.(unknown context at 0x106932738).bookings(bookieName: "", bookieNumber: "", booked: "false", bookingTime: "10:00"),

Also, if i want to be able to access a single value lets say the first item with the key "0" -> bookieName, how would i do that using loginDetails

Answer 1

Firs booked is a Bool and no need for private enum Codingkeys if you won't rename the keys

struct Booking: Codable {

   let bookieName : String
   let bookieNumber: String
   let booked: Bool
   let bookingTime: String

}

Second decode like this

let loginDetails = try decoder.decode([String:Booking].self, from: response.data!)

Answer 2

The root object is a dictionary with String keys and Bookings values – please name structs with a starting capital letter.

So you have to decode

let loginDetails = try decoder.decode([String:Bookings].self, from: response.data!)
