Swift Table view Fail to Load the data - json

Question

I am new in swift . I am trying the display the data into tableview controller from API . Here is the api link . https://api.nasa.gov/mars-photos/api/v1/rovers/curiosity/photos?sol=1000&api_key=DEMO_KEY. I create model based on the json property . Here is the model code .
import Foundation
struct Welcome: Codable {
let photos: [Photo]
}
// MARK: - Photo
struct Photo: Codable {
let id, sol: Int
let camera: Camera
let imgSrc: String
let earthDate: String
let rover: Rover
enum CodingKeys: String, CodingKey {
case id, sol, camera
case imgSrc = "img_src"
case earthDate = "earth_date"
case rover
}
}
// MARK: - Camera
struct Camera: Codable {
let id: Int
let name: String
let roverID: Int
let fullName: String
enum CodingKeys: String, CodingKey {
case id, name
case roverID = "rover_id"
case fullName = "full_name"
}
}
// MARK: - Rover
struct Rover: Codable {
let id: Int
let name, landingDate, launchDate, status: String
enum CodingKeys: String, CodingKey {
case id, name
case landingDate = "landing_date"
case launchDate = "launch_date"
case status
}
}
From this model I want to user Rover struct fields like id and status and display those property into table view cell .
Here is the network Manager code .
class NetworkManager{
func fetchData(completion: #escaping ([Rover]) -> Void) {
if let url = URL(string: "https://api.nasa.gov/mars-photos/api/v1/rovers/curiosity/photos?sol=1000&api_key=DEMO_KEY") {
URLSession.shared.dataTask(with: url) { data, urlResponse, error in
if let data = data {
do {
let result = try JSONDecoder().decode([Rover].self, from: data)
completion(result)
} catch let error {
print(error.localizedDescription)
}
}
}
.resume()
}
}
}
Here code for view controller .
class ViewController: UIViewController {
#IBOutlet weak var tableView: UITableView!
private var posts = [Rover]()
private let networkManager = NetworkManager()
private var rowSelected = 0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setUpUI ()
fetchData()
}
private func setUpUI () {
tableView.dataSource = self
tableView.delegate = self
}
private func fetchData() {
networkManager.fetchData { [weak self] array in
self?.posts = array
DispatchQueue.main.async {
self?.tableView.reloadData()
}
}
}
}
extension ViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
rowSelected = indexPath.row
performSegue(withIdentifier: "cell", sender: nil)
}
}
extension ViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return posts.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let row = indexPath.row
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
let post = posts[row]
cell.textLabel?.text = String(post.id)
cell.detailTextLabel?.text = post.status
return cell
}
}
Here is the console result when i run the code , it is saying The data couldn’t be read because it isn’t in the correct format.
