Passing data from UIView to UIViewController using protocol - ios

Question

I'm trying to pass data from UIView contains UITableView to UIViewController but unfortunately, it doesn't work.
Model:
struct Recipes: Codable {
let recipes: [Recipe]
}
struct Recipe: Codable {
let title: String?
let image: String?
let pricePerServing: Double?
let readyInMinutes, servings: Int?
}
The data should be passed from this view
HomeView:
protocol RecipesDetailsSelectActionDelegate: class {
func recipeDetails(recipeTitle: String)
}
class HomeView: UIView {
var recipes: Recipes?
var recipesDetails = [Recipe]()
let indicator = ActivityIndicator()
weak var homeViewDidSelectActionDelegate: HomeViewDidSelectActionDelegate?
weak var recipeDetailsViewSelectActionDelegate: RecipesDetailsSelectActionDelegate?
override init( frame: CGRect) {
super.init(frame: frame)
layoutUI()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
lazy var foodTableView: UITableView = {
let foodTableView = UITableView()
foodTableView.translatesAutoresizingMaskIntoConstraints = false
foodTableView.backgroundColor = .customVeryLightGray()
foodTableView.delegate = self
foodTableView.dataSource = self
foodTableView.register(HomeTableViewCell.self, forCellReuseIdentifier: "HomeTableViewCell")
foodTableView.rowHeight = UITableView.automaticDimension
foodTableView.estimatedRowHeight = 100
foodTableView.showsVerticalScrollIndicator = false
foodTableView.separatorStyle = .none
return foodTableView
}()
}
extension HomeView: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return recipesDetails.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "HomeTableViewCell", for: indexPath) as! HomeTableViewCell
let url = URL(string: recipesDetails[indexPath.row].image ?? "Error")
cell.foodImage.kf.setImage(with: url)
cell.foodTitle.text = recipesDetails[indexPath.row].title
if let readyInMin = recipesDetails[indexPath.row].readyInMinutes {
cell.cookingTimeInfoLabel.text = "\(readyInMin) Minutes"
}
if let pricePerServing = recipesDetails[indexPath.row].pricePerServing {
cell.priceInfoLabel.text = String(format: "%.2f", pricePerServing / 100)
}
if let serving = recipesDetails[indexPath.row].servings {
cell.servesInfoLabel.text = "\(serving)"
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
recipeDetailsViewSelectActionDelegate?.recipeDetails(recipeTitle: recipesDetails[indexPath.row].title ?? "Error")
}
}
HomeViewController:
class HomeViewController: UIViewController {
lazy var mainView: HomeView = {
let view = HomeView(frame: self.view.frame)
view.recipeDetailsViewSelectActionDelegate = self
return view
}()
override func loadView() {
super.loadView()

}
}
extension HomeViewController: RecipesDetailsSelectActionDelegate {

vc.mainView.recipeTitle = recipeTitle
self.show(vc, sender: nil)
