I’m currently using the posts to save the scroll position, but is there was way to save the exact scroll position so it stops jumping around and saves precisely.

 @State private var lastViewedPostId: String? {
        didSet {
            if let id = lastViewedPostId {
                UserDefaults.standard.set(id, forKey: "lastViewedPostId")
            }
        }
    }

ScrollViewReader { scrollProxy in
                    ScrollView(showsIndicators: false) {
                        LazyVStack(spacing: 14) {
                            if viewModel.posts.count > 0 {
                                ForEach(sortedPostsForYou) { post in
                                    PostCell(postWithUser: post, appData: appData)
                                        .id(post.id)
                                        .onAppear {
                                            lastViewedPostId = post.id
                                        }
                                }
                                .padding(.top, 17)
                                
                            } else {
                                LoadingModifier()
                                    .padding(.top, 230)
                            }
                        }
                    }
                    .tag(0)
                    .onAppear {
                        if let savedId = lastViewedPostId {
                            DispatchQueue.main.asyncAfter(deadline: .now() + 0.02) {
                                withAnimation(.easeIn) {
                                    scrollProxy.scrollTo(savedId, anchor: .center)
                                }
                            }
                        }
                    }
                }

I tried using the posts but it did not work smoothly.
