This is what running the app in simulator looks like just blank instead of being filled the labels with the data coming from the API :(

And this is what it should be, ofc with the labels on the right side filled but when I enter the code to fill the cell with data from api to labels it shows nothing ?

class MonitorimiViewController: UIViewController {

@IBOutlet weak var monitorimiTableView: UITableView!


var listOfVechicle = [Vehicles]()
let tableView = UITableView()


var id = "6438367CC43848B497FE4604AF465DSSS6A"

override func viewDidLoad() {
    super.viewDidLoad()
    
    
    monitorimiTableView.delegate = self
    monitorimiTableView.dataSource = self
    monitorimiTableView.rowHeight = 225
    
    
    APICaller.shared.getVehicles(for: id) {[weak self] (result) in
        guard let self = self else { return }
        
        switch result {
        case .success(let vehicle):
            self.listOfVechicle = vehicle
            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        case .failure(let error):
            print(error)





extension MonitorimiViewController: UITableViewDelegate, UITableViewDataSource{

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return listOfVechicle.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    guard let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as? MyCustomCell1 else {return UITableViewCell()}
    //You can Access Your Vehicles Model Values Here one by one
    let currentVechicle = listOfVechicle[indexPath.row]
    cell.veturaOutlet.text = currentVechicle.Plate
    cell.shpejtsiaAktualeOutlet.text = currentVechicle.Speed
    cell.perditsuarOutlet.text = currentVechicle.LastCommunicationDate
    return cell
}

}

And this is the structure which I am calling 5 of the var to my cells:

struct Vehicles: Codable {



var  IDVehicle: Int?
var  Title: String?
var  RegistrationDate: String?
var  ExpireDate: String?
var  Department: String?
var  Identification: String?
var  Speed: String?
var  Latitude: Double?
var  Longitude: Double?
var  Angle: Int?
var  Status: Int?
var  InputValue: Int?
var  Plate: String?
var  LastCommunicationDate: String?
var  Passengers: Int?
var  Driver: String?

}

CodePudding user response：

you need to call reloadData for the tableview which is connected from IBOutlet not for Dummy TableView

  class MonitorimiViewController: UIViewController {
    
    @IBOutlet weak var monitorimiTableView: UITableView!
    
    
    var listOfVechicle = [Vehicles]()
    //No Need For the tableView Creation ,So pls remove that,beacuse you had create and connected the tableview through storyboard(IBoutlet)
    //let tableView = UITableView()
    
    var id = "6438367CC43848B497FE4604AF465DSSS6A"
    
    override func viewDidLoad() {

        monitorimiTableView.delegate = self
        monitorimiTableView.dataSource = self
        monitorimiTableView.rowHeight = 225
        fetchAndReloadData()
    }
    
    func fetchAndReloadData(){
        APICaller.shared.getVehicles(for: id) {[weak self] (result) in
            guard let self = self else { return }
            
            switch result {
            case .success(let vehicle):

                DispatchQueue.main.async {
                    //Instead of below code
                    // self.tableView.reloadData()
                    // use like Below
                    self.monitorimiTableView.reloadData()
                }
            case .failure(let error):
