Post data containing array of structs in swift

Question

Here is the JSON I need to post:

{
    "results": [
        {
            "case_id": 1,
            "status_id": 5,
            "comment": "This test failed"           

        },
        {
            "case_id": 2,
            "status_id": 1,
            "comment": "This test passed",

        },

        ..

        {
            "case_id": 1,
            "assignedto_id": 5,
            "comment": "Assigned this test to Joe"
        }

        ..
    ]
}

What I've tried doing is this :

let parameters = [
                "results" : data
                ] as [String : Any]

            let postData =  try JSONSerialization.data(withJSONObject: parameters, options: [])

Here, data is an array of structs of the type (data:[param]) :

struct param {
        var status_id: Int
        var case_id: String
        var comment: String
    }

The code fails at JSONSerialization. It enters the catch() block. I tried giving the parameters like this and it worked,

let parameters = [ "results" : [
       [
            "case_id": "20275",
            "status_id": 5,
            "comment": "This test failed"           
        ],
        [
            "case_id": "20276",
            "status_id": 1,
            "comment": "This test passed",
        ],
                    ]] as [String : Any]

How can I reproduce this structure? Because I can't hard code the values of status id's and case id's. I store the status id's and case id's in arrays.I thought creating an array of structs and substituting the id values will be enough, unfortunately it's not working. How do I post the data then?

The param should be a dictionary do not make it with struct. — Salman Ghumsani

@SalmanGhumsani, an array of dictionaries? Each dictionary containing the id's and the comment? — Coder95

@SalmanGhumsani, thank you very much , it worked. But I had to use [String : [[String:AnyObject]]] instead. — Coder95

The 'param' should be a dictionary do not make it with struct.

The request body data type is: [String:[[String,Any]]]
