Present results with alamofire/Swift - json

Question

When I try to present the results I received this message "Response could not be decoded because of error:
The data couldn’t be read because it isn’t in the correct format."
This is my format and its right I think.
import Foundation
// MARK: - Response
struct Response: Codable {
let code: Int
let meta: Meta
let data: [Datum]
}
// MARK: - Datum
struct Datum: Codable {
let id, userID: Int
let title, body: String
enum CodingKeys: String, CodingKey {
case id
case userID = "user_id"
case title, body
}
}
// MARK: - Meta
struct Meta: Codable {
let pagination: Pagination
}
// MARK: - Pagination
struct Pagination: Codable {
let total, pages, page, limit: Int
}
also I try with this code to view the result.
private func fetchData() {
self.task = AF.request(self.baseUrl, method: .get, parameters: nil)
.publishDecodable(type: [Response].self)
.sink(receiveCompletion: {(completion) in
switch completion {
case .finished:
()
case .failure(let error):
print(String(describing: error))
//print(error.localizedDescription)
}
}, receiveValue: {[weak self ](response) in
switch response.result {
case .success(let model): self?.presenters = model.map {PostPresenter(with: $0)}
case.failure(let error):
print(String(describing: error))
// print(error.localizedDescription)
}
})
}
And my post presenter code is this
struct PostPresenter: Identifiable {
let id = UUID()
let title: String
init(with model:Response) {
self.title = model.data
}
}

Answer 1

Two mistakes
The root object is a dictionary so it's (type: Response.self)
and model.data is [Datum] so declare
struct PostPresenter: Identifiable {
let id = UUID()
let data: [Datum]
init(with response: Response) {
self.data = response.data
}
}
And in a Codable context print the error always print(error), not print(String(describing: error)) and never print(error.localizedDescription)

Answer 2

My right Post presenter
struct PostPresenter: Identifiable {
let id = UUID()
let data: [Datum]
init(with response: Response<[Datum]>) {
self.data = response.data
}
init() {
data = []
}
}
And my finally format as I right.
struct Response<T: Decodable>: Decodable {
let code: Int
let meta: Meta
let data: T
}
// MARK: - Datum
struct Datum: Decodable {
let id, userID: Int
let title, body: String
enum CodingKeys: String, CodingKey {
case id
case userID = "user_id"
case title, body
}
}
// MARK: - Meta
struct Meta: Decodable {
let pagination: Pagination
}
// MARK: - Pagination
struct Pagination: Decodable {
let total, pages, page, limit: Int
}
And finally my homeview and how I present
struct HomeView: View {
#ObservedObject var viewModel = HomeAPIViewModel()
var body: some View {
ZStack {
Color(.white)
// Present the API Here
List(self.viewModel.presenter.data, id: \.id) {
Text($0.title)
}
.padding()
}
}
}
