im making a covid app that take data of the number of cases in my city, i made a json file and parse data
i passed the data to a table view like i wanted bur the thing is that in the casosViewcontroller i cant pass the data. is nil

Git: https://github.com/CarlosCardonaM/covidGto

struct CasosData: Codable {

var fecha:String
var semaforo:String
var casosConfirmados:Int
var casosEnInvestigacion:Int
var casosDescartados:Int
var defunciones:Int
var casosRecuperados:Int
var casosDeTransmisionComunitaria:Int

}

public class DataLoader {

@Published var casosData = [CasosData]()

init() {
    load()
}
func load() {
    if let fileLocation = Bundle.main.url(forResource: "CoronavirusGuanajuato", withExtension: "json") {
        
        // Do catch
        do {
            let data = try Data(contentsOf: fileLocation)
            let jsonDecoder = JSONDecoder()
            let dataFromJson = try jsonDecoder.decode([CasosData].self, from: data)
            
            self.casosData = dataFromJson
        }
        catch {
            print(error)
        }
    }
}

}

class ViewController: UIViewController {

@IBOutlet weak var imagenGto: UIImageView!
@IBOutlet weak var datosButton: UIButton!
@IBOutlet weak var infoButton: UIButton!


override func viewDidLoad() {
    super.viewDidLoad()
    title = "COVID-19 Gto"
    view.backgroundColor = .white
    
    imagenGto.layer.borderWidth = 1
    imagenGto.layer.masksToBounds = false
    imagenGto.layer.borderColor = UIColor.black.cgColor
    imagenGto.layer.cornerRadius = imagenGto.frame.height / 2
    imagenGto.clipsToBounds = true
    
    datosButton.layer.cornerRadius = 10
    
}

}

class DatosViewController: UIViewController {

let casosData = DataLoader().casosData
var casos:CasosData?
