you can use Codable to create JSON model and in that you can customise you key.

I assume your JSON response ({"status":"success","msg":"deleted","pro_data":[]}) available in Data format.

So, See the following code which are used to create JSON model for your data.

struct WSModel: Codable {
    var status  : String?
    var msg     : Int?
    var Images  : [Any]?

    enum CodingKeys: String, CodingKey {
        case currentPage    = "status"
        case msg            = "msg"
        case Images         = "pro_data"
    }
}

Due to there aren't any data type inside your array I have keep Any type of data.This code is work for when keys in response are "status", "msg", "pro_data".

Try this code and let me know still an issue. I hope this will work for you.

I assume your issue is that you want to continue to use "Images":[] key, without having to change rest of your code.

In your JSON response that you want to change, you can try something like this.

response["Images"] = response["pro_data"]

@Jhony, When you do this, and then print your object `response`, doest it not have the new key? – Shamas S Sep 03 '18 at 09:01
