ContentView.swift

import SwiftUI

struct MessageInput: View {
    @State private var text = ""
    @FocusState private var isFocused: Bool

    var body: some View {
        HStack {
            TextField("Enter your message…", text: $text)
                .textFieldStyle(.roundedBorder)
                .padding(.trailing)
                .focused($isFocused)
        }
        .padding(.horizontal)
        .padding(.vertical, 8)
    }
}

struct ContentView: View {
    var colors: [Color] = [.red, .brown, .green, .cyan, .blue, .purple]

    var body: some View {
        NavigationStack {
            ScrollViewReader { scrollView in
                VStack(spacing: 0) {
                    ScrollView {
                        VStack(spacing: 0) {
                            ForEach(colors.indices, id: \.self) { colorIndex in
                                Rectangle()
                                    .fill(colors[colorIndex])
                                    .frame(height: 200)
                                    .id(colorIndex)
                            }
                        }
                    }
                    .scrollDismissesKeyboard(.interactively)     // allow dismissing the keyboard interactively
                    .navigationTitle("Chat")
                    .navigationBarTitleDisplayMode(.inline)
                    .onAppear() {
                        scrollView.scrollTo(colors.indices.last, anchor: .bottom)
                    }

                    MessageInput()
                        .background(Material.thin)
                }
                .background(.red)
            }
        }
    }
}

Did you find a solution?

No, sorry. I've just tested it now again... it simply is not interactive enough to keep up with the keyboard dismiss gesture of the user.
According to WWDC23 video Keep up with the keyboard there is a way with UIKit using layout constraints... but they do not go into details for SwiftUI.
