passing data (json) to another controller in swift 5.2 con Alamofire - ios

Question

I have a Login view that asks for a card and password. I consult an API and if the entered data is correct, it sends me a JSON like this. Which return has the button method? How do I send that data to the other view? I occupy Alamofire 5.0 and have my Model class.
#IBAction func myButtonIngresarAction(_ sender: Any) {
guard let carnet = self.txtCarnet.text else {return}
guard let contrasena = self.txtPassword.text else {return}
let ingresologinmodel = IngresoLoginModel(usuario: carnet, password: contrasena)
self.apiCall(IngresoLoginModel: ingresologinmodel){
(result) in
switch result{
case .success(let json):
print(json)
**//This is where I want to send that json with the data to the other view. ******
case .failure(let err):
print(err.localizedDescription)
}
}
}
enum ApiErros: Error {
case custom(message : String)
}
typealias Handler = (Swift.Result<Any?, ApiErros>) -> Void
func apiCall(IngresoLoginModel: IngresoLoginModel, completionHandler: #escaping Handler)
{
let header: HTTPHeaders = [
.contentType("application/json")
]
AF.request("https://url/xxxx/api/Login", method: .post, parameters: IngresoLoginModel,
encoder: JSONParameterEncoder.default, headers: header).response{ response in
debugPrint(response)
switch response.result{
case .success(let data):
do{
let json = try JSONDecoder().decode([LoginModel].self, from: data!)
print(json)
if response.response?.statusCode == 200{
completionHandler(.success(json))
}else{
completionHandler(.failure(.custom(message: "Por favor verifica tu internet")))
}
}
catch
{
print(error)
completionHandler(.failure(.custom(message: "Problemas")))
}
case .failure(let err):
print(err.localizedDescription)
}
}
}
Class model
struct LoginModel: Codable {
let idEmpleado: Int
let Nombre: String
let CodEmpleado: String
let password: String
let idPerfil: Int
let activo: Int
let Descripcion: String
let idRegion: Int
let correo: String
}
This is the json that the Api sends me the data changes them for these example
{
"idEmpleado": 1,
"nombre": “test”,
"codEmpleado": “000000”,
"password": “123”,
"idPerfil": 4,
"activo": 1,
"Descripcion": “test”,
"idregion": 1,
"correo": “test#test.com"
}

Answer 1

many way like create a variable to save this json in OtherViewController and call, self?.otherViewController.json = json

Answer 2

use didSet
var page = [Datas]() {
didSet {
self.myVariable = page[0].date!
}
}

Answer 3

typealias Handler = (Swift.Result <[LoginModel]?, ApiErros>) -> Void
#IBAction func myButtonIngresarAction(_ sender: Any) {
guard let carnet = self.txtCarnet.text else {return}
guard let contrasena = self.txtPassword.text else {return}
let ingresologinmodel = IngresoLoginModel(usuario: carnet, password: contrasena)
self.apiCall(IngresoLoginModel: ingresologinmodel){
(result) in
switch result{
case .success(let json):
print(json)
//Here is that I do not know how to send it to the other controller all the json
let viewControllerB = HomeMenuViewController()
viewControllerB.datosPersonales = json!
self.navigationController?.pushViewController(viewControllerB, animated: true)
case .failure(let err):
print(err.localizedDescription)
}
}
}
second controller
class HomeMenuViewController: UIViewController {
#IBOutlet weak var mylabel: UILabel!
var datosPersonales = [LoginModel]()
override func viewDidLoad() {
super.viewDidLoad()
print("***************")
print(datosPersonales)
print("***************")
}
}
