ObservedObject is still in memory after the view is dismissed, Memory Leak? – Ios swift

I’m making an app with SwiftUI and UIkit, I use UIkit for the main app controller and navigation, and I use SwiftUI for app design.

The app works very well, but I’m worried about the memory leaks. This is because the ViewModels I use to pass data between views don’t call desinit whene the view disappears. I know that in SwiftUI views are not disposed immediately, but since I’m using UIKit to navigate I don’t know what the problem is.

//The ViewModel for each user fetched
internal class UserViewModel: ObservableObject, Identifiable {
    
    //MARK: - Propeties var currentListener: ListenerRegistration?
    
    @Published var request: Request?
    @Published var user: User
    
    init(user: User) {
        self.user = user
        getRequest()
        fetchAdmins()
    }
    
    deinit {
        //Dosnt get called removeListener()
    }
    
    func getRequest() {
        guard let uid = Auth.auth().currentUser?.uid else {return}
        guard let id = id else {return}
        
        self.currentListener = Collections.requests(id).document(uid).addSnapshotListener { snapshot, error in
            
            if let error = error {
                print(error.localizedDescription)
                return
            }
            
            if ((snapshot?.exists) != nil) {
                if let request = try? snapshot!.data(as: Request.self) {
                    DispatchQueue.main.async {
                        self.request = request
                    }
                }
            }
        }
    }
    
    func removeListener() {
        self.currentListener?.remove()
    }
}
}

//The ViewModel to fetch all the users ViewModels
class UsersViewModel: ObservableObject {
    @Published var users = [UserViewModel]()
    
    func fetch() {
        DispatchQueue.global(qos: .background).async {
            Collections.users.getDocuments(completion: { snapshot, err in
                
                guard let documents = snapshot?.documents else { return } let users = documents.compactMap({ try? $0.data(as: User.self) })
                
                users.forEach { user in
                    let vm = UserViewModel(user: user)
                    DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
                        self.users.append(vm)
                    }
                }
            })
        }
    } }

//Show the users cells with the ViewModel
struct HomeView: View {
    @ObservedObject var usersViewModels: UsersViewModel
    
    //MARK: - Init
    init() {
        self.usersViewModels = UsersViewModel()
    }
    
    var body: some View {
        ListView(content: {
            ForEach(usersViewModels) { usersViewModel in
                UserCell(viewModel: usersViewModel).id(user.id)
            }
        })
    }
}

This is how I navigate between controllers and views of my app. I don’t use NavigationLinks:

    public static func push<Content: View>(view: Content) {
        DispatchQueue.main.async {
 guard let tabBarController = UIApplication.rootViewController as? UITabBarController, let navigationController = tabBarController.selectedViewController as? UINavigationController else { return nil }

            if let navigationController = UIApplication.getCurrentNavigationController() {
                navigationController.pushViewController(HostingController(content: view), animated: true)
            }
        }
    }

Does anyone know if this method that I am using to navigate can cause me memory problems? And you know why my app doesn’t reduce its memory every time I close a window, it just increases more and more.
