Values of Array of struct are nil in swift - ios

Question

can someone explain to me what am I doing wrong in this case, it goes into case success but it throws a thread The «Unexpectedly found nil while unwrapping an Optional value» Error at the line self.actions = dataRoles.data like highlighting .data
The JSON looks like
{
"company_id": 1,
"data": [
{
"code": "master",
"id": 1,
"inserted_at": "01/02/2021 09:38",
"name": "Master Admin"
},
{
"code": "user",
"id": 2,
"inserted_at": "01/02/2021 09:38",
"name": "User"
}
],
"draw": 1,
"page_number": 1,
"page_size": 100,
"recordsFiltered": 2,
"recordsTotal": 2,
"total_pages": 1
}
The Struct is
import Foundation
struct ListRoles: Codable {
let companyID: Int!
let data: [DataRoles]!
let draw, pageNumber, pageSize, recordsFiltered: Int!
let recordsTotal, totalPages: Int!
private enum CodingKeys: String, CodingKey {
case companyID = "company_id"
case data, draw
case pageNumber = "page_number"
case pageSize = "page_size"
case recordsFiltered, recordsTotal
case totalPages = "total_pages"
}
}
struct DataRoles: Codable {
let code: String!
let id: Int!
let insertedAt, name: String!
private enum CodingKeys: String, CodingKey {
case code, id
case insertedAt = "inserted_at"
case name
}
}
And the ViewModel that I am working on looks like this
class ListRolesViewModel {
weak var delegate: ListRolesViewModelDelegate?
private var action: ListRoles!
private var actions: [DataRoles] = []
func getRoles() {
guard let accessToken = KeychainWrapper.standard.string(forKey: "codaxim_access_token") else { return }
self.delegate?.willGetRoles(self)
Alamofire.request(Url.shared.listAllRoles, method: .get, headers: ["Authorization" : "Bearer " + accessToken])
.responseJSON { response in
switch response.result {
case .success:
guard let dataRoles = response.data?.decode(for: ListRoles.self) else { return }
self.action = dataRoles
self.actions = dataRoles.data
self.delegate?.didGetRoles(self)
print("Success")
break
case .failure:
self.delegate?.didFailGetRoles(self)
print("Alamofire error: \(String(describing: response.result.error))")
break
}
}
}
}
I have tried a couple of ways and none it seems to work, from changing the guard let to if let, adding ! in my struct... If you have any idea what it can be it would help me a lot! Thanks in advance.
