Get object at the start of view swiftui

Question

I have a view and I want to load the data from the database from the start of the view, because I want to edit the profile of my user.
So whenever I will start the my view, the data will be loaded. This is my code but it gives me an exception on the TextField.

struct ProfileView: View {
    @State var  myUser = User()
    var repo = myRepo()

     var body: some View {
        VStack{
            Form{
                Section(header: Text("edit the name")){
                    TextField("Nume produs", text: self.myUser.name) //IT DOES NOT WORK HERE
                }
            }
        }.onAppear(){
            getMyUser()    
        }

    func getMyUser(){
        Task{
            do{
                try await repo.getUserProfile().watch(block: {item in
                    self.myUser = item as! User
                })
            }catch{
                print("error")
            }
        }
    }
}

This just does not work when I put as a TextField What is the best way to have the data of my object (myUser) right away on the start of the view?

Just init the String as empty and create the @Binding like so:

import SwiftUI

    struct ProfileView: View {
        @State var  myUser = ""
        
        var body: some View {
            VStack{
                Form{
                    Section(header: Text("edit the name")){
                        TextField("Nume produs", text: $myUser) //IT DOES NOT WORK HERE
                    }
                }
            }.onAppear(){
                getMyUser()
            }
        }
        
        func getMyUser() {
            Task{
                do{
                    try await Task.sleep(nanoseconds: 3_000_000_000)
                    
                    myUser = "HELLO"
                }catch{
                    print("error")
                }
            }
        }
    }
