How to create a Swift model for the JSON file with dynamic key?

Question

I am trying to write a Swift Codable model for the below JSON.

{
    "batchcomplete": "",
    "query": {
        "pages": {
            "26667" (The problem is here): {
                "pageid": 26667,
                "ns": 0,
                "title": "Spain",
                "contentmodel": "wikitext",
                "pagelanguage": "en",
                "pagelanguagehtmlcode": "en",
                "pagelanguagedir": "ltr",
                "touched": "2020-03-14T18:03:48Z",
                "lastrevid": 945549863,
                "length": 254911,
                "fullurl": "https://en.wikipedia.org/wiki/Spain",
                "editurl": "https://en.wikipedia.org/w/index.php?title=Spain&action=edit",
                "canonicalurl": "https://en.wikipedia.org/wiki/Spain"
            }
        }
    }
}

The problem is that one of the key changes every time I query. Marked the in the above JSON as (The problem is here)

How to parse the above JSON file with JSONDecoder?

This can be easily parsed with libraries like SwiftyJSON.

The point is in making let pages: [String:Item] Use

// MARK: - Root
struct Root: Codable {
    let batchcomplete: String
    let query: Query
}

// MARK: - Query
struct Query: Codable {
    let pages: [String:Item]
}


// MARK: - Item
struct Item: Codable {
    let pageid, ns: Int
    let title, contentmodel, pagelanguage, pagelanguagehtmlcode: String
    let pagelanguagedir: String
    let touched: Date
    let lastrevid, length: Int
    let fullurl: String
    let editurl: String
    let canonicalurl: String
}

let res = try JSONDecoder().decode(Root.self, from: data)
