如何解码 swift 中的数组？

Question

Hi I get response from server like so:

[
    {
        "success": {
            "/lights/1/state/on": true
        }
    }
]

and I'd like to encode it how to do it? I try something like this but it didn't work:

struct ResponseModel: Decodable {
    
    var response: [ResponseDataModel]

    struct ResponseDataModel: Decodable {
        var status: [String: String]
    }
}

let decodedResponse = try JSONDecoder().decode(ResponseModel.self, from: data)
                        
print(decodedResponse)

You mean decode it. The property is not response should be success , and you are receiving an array not a dictionary. Note also your dictionary value type should be a Bool not a String :

let json = """
[
    {
        "success": {
            "/lights/1/state/on": true
        }
    }
]
"""

struct Response: Decodable {
    var success: [String: Bool]
}

let decodedResponse = try JSONDecoder().decode([Response].self, from: Data(json.utf8))
if let firstElement = decodedResponse.first {
    print(firstElement) // "Response(success: ["/lights/1/state/on": true])\n"
}
