How can I decode a dictionary from a JSON when I don't know the keys of the dictionary? [duplicate]

Answer 1

you can use https://app.quicktype.io to create Codable models fast and easy. For example the following code is generated using that service with the response of that request you need. I didn't check it but should work fine.

// This file was generated from JSON Schema using quicktype, do not modify it directly.
// To parse the JSON, add this file to your project and do:
//
//   let stock = try? JSONDecoder().decode(Stock.self, from: jsonData)

import Foundation

// MARK: - Stock
struct Stock: Codable {
    let metaData: MetaData
    let timeSeries5Min: [String: TimeSeries5Min]

    enum CodingKeys: String, CodingKey {
        case metaData = "Meta Data"
        case timeSeries5Min = "Time Series (5min)"
    }
}

// MARK: - MetaData
struct MetaData: Codable {
    let the1Information, the2Symbol, the3LastRefreshed, the4Interval: String
    let the5OutputSize, the6TimeZone: String

    enum CodingKeys: String, CodingKey {
        case the1Information = "1. Information"
        case the2Symbol = "2. Symbol"
        case the3LastRefreshed = "3. Last Refreshed"
        case the4Interval = "4. Interval"
        case the5OutputSize = "5. Output Size"
        case the6TimeZone = "6. Time Zone"
    }
}

// MARK: - TimeSeries5Min
struct TimeSeries5Min: Codable {
    let the1Open, the2High, the3Low, the4Close: String
    let the5Volume: String

    enum CodingKeys: String, CodingKey {
        case the1Open = "1. open"
        case the2High = "2. high"
        case the3Low = "3. low"
        case the4Close = "4. close"
        case the5Volume = "5. volume"
    }
}
