Decodable Json, function doesn't run at all? - ios

Question

I know this decodable json question has been asked a lot of times, in-fact i was able to do the retreival of data for one of my other projects. However, I cant seem to get this to work. IT is suppose to retrieve the data, decode it and store it. However, my print function was never ran. I don't see the "executed" print and moreover. It does print httpResponse with the headers from the api so I know it is working and it has a response.
Decodable
struct GetId: Decodable {
let id : String?
let deck_id : String?
var completed_at : String?
let created_at : String?
let locale_key : String?
let profile_id : String?
let recommendation_id : String
let package_id : String?
let status : String?
let scoring_scale : String?
}
Sample Response
{
"id": "XXXXXXX-XXX-4c6a-XXXX-1XXXXXXX223",
"deck_id": "career-deck",
"completed_at": null,
"created_at": 1551867228744,
"locale_key": "en-US",
"profile_id": "XXXXXXX-XXX-4c6a-XXXX-1XXXXXXX223",
"recommendation_id": null,
"package_id": null,
"status": "created",
"scoring_scale": "NORMAL"
}
My function
func requestId()
{
let headers = [
"Authorization": "Basic XXXxxxxXXxxXXXXxxxXXX:x",
"Content-Type": "application/json",
"cache-control": "no-cache"
]
let parameters = ["deck_id": "career-deck"] as [String : Any]
let postData = try? JSONSerialization.data(withJSONObject: parameters, options: [])
let request = NSMutableURLRequest(url: NSURL(string: "https://api.traitify.com/v1/assessments")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = (postData as! Data)
//let session = URLSession.shared
//let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
if let getIdd = try? JSONDecoder().decode([GetId].self, from: data!){
getId = getIdd
print(getId[0].id)
print("executed")
}
}
}
task.resume()
}

Answer 1

From your example, created_at is not a string (it is a numeric value) and recommendation_id needs to be optional (like all the other fields).
Also, your example is a single record, but you are decoding an array of objects. Change the decode to be JSONDecoder().decode(GetId.self, from: data!)
