SwiftUI scroll to item after async load - list

Question

I do async load of items from network .onAppear, after that my ViewModel force to redraw swiftUI view. After that i need scroll list to particular item. I do it .onRecieve, problem is that view redrawing and scrolling perform almost same time, but indeed scrolling goes first as i understand, so i need add ugly hack - delay, than it works fine.
Question is there are some another approach how to postpone scrolling after view refresh.
struct ItemsListView: View {
#Binding var selectedItem: Item?
#ObservedObject var viewModel: ViewModel
var body: some View {
ScrollViewReader { proxy in
List(viewModel.state.items) { item in
let selected = item.id == selectedItem?.id
self.createCell(item: item, selected: selected)
.onTapGesture {
selectedItem = item
}
}
.listStyle(SidebarListStyle())
.navigationBarTitleDisplayMode(.inline)
.onAppear {
self.viewModel.trigger(.getItems) // triggers async load of items
}
.onReceive(viewModel.$state) { state in
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { // hack to give a time redraw ItemsListView
withAnimation {
proxy.scrollTo(selectedItem?.id, anchor: .center)
}
}
}
}
}
View Model code, it's real but a bit simplified for this topic
class ViewModel: ObservableObject {
struct State {
var items = [Item]()
}
enum Event {
case getItems
}
func trigger(_ event: Event) {
switch event {
case .getItems: self.getItems()
}
}
#Published var state = State()
init(dataFetcher: RemoteDataProvider) {
self.dataFetcher = dataFetcher
super.init()
}
private func getItems() {
dataFetcher.getItems()
.sink { result in
if case .failure(let err) = result {
print("Retrieving car items list failed:\(err)")
}
} receiveValue: {[weak self] items in
self?.state.items = items
}
.store(in: &subscriptions)
}
}
