Swift: decode JSON with unknown keys? [duplicate]-CodePudding

I would like to decode a simple JSON file, the thing is that the top keys will all be different:

{
    "pikachu": {
        "name": "Pikachu",
        "number": 25
    },
    "bulbasaur": {
        "name": "Bulbasaur",
        "number": 1
    },
    "caterpie": {
        "name": "Caterpie",
        "number": 10
    }   
}

I have this model so far:

struct Pokemon: Decodable {
    //var key: ?
    var pokemonInfo: PokemonInfo
}

struct PokemonInfo: Decodable {
    var name: String
    var number: Int
}

But then I don't know how to set the Pokemon's key, as well as what to pass as a parameter for JSONDecoder.

let decodedResult = try JSONDecoder().decode([Pokemon].self, from: data)

typeMismatch(Swift.Array, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected to decode Array but found a dictionary instead.", underlyingError: nil))

What to do here?

Thank you for your help

CodePudding user response：

There is no array and no key pokemonInfo in the JSON.

As the keys are actually irrelevant the easiest solution is to decode [String:PokemonInfo] and map it to the values

let decodedResult = Array(try JSONDecoder().decode([String:PokemonInfo].self, from: data).values)
