Pass an Int from UIKit to SwiftUI

Forums > SwiftUI

In the case below, I want to be able to change the value of the count to a property of the view controller, based on the lifecycle I could use a Coordinator and set the delegate but what am I even delegating off? 🤔

protocol MyRoutesSectionViewControllerRepresentable: UIViewControllerRepresentable {
  var myRoutesSectionViewObject: MyRoutesSectionViewObject { get set }

class MyRoutesSectionViewObject: ObservableObject {
  var title: String
  var iconString: String
  @Published var count: Int
  var badgeIconString: String?

  init(title: String, iconString: String, count: Int, badgeIconString: String? = nil) {
    self.title = title
    self.iconString = iconString
    self.count = count
    self.badgeIconString = badgeIconString

struct BMPlannedRoutesView: MyRoutesSectionViewControllerRepresentable {
  @ObservedObject var myRoutesSectionViewObject = MyRoutesSectionViewObject(title: "Planned",
                                                                   iconString: "plannedIcon",
                                                                   count: 0)

  func makeUIViewController(context: Context) -> BMPlannedRoutesViewController {
    return BMPlannedRoutesViewController.instantiateFromStoryboard(name: "MyRoutes")

  func updateUIViewController(_ uiViewController: BMPlannedRoutesViewController, context: Context) {
    uiViewController.dottedArrowView.isHidden = true
