我正在创建一个聊天机器人，它最终将使用ChatGPT API。现在我正在创建聊天部分。我可以在textfield中输入并添加到数组中，然后使用Text（）显示数组，如代码所示。但是，当键入一个长消息时，它只会显示2行，然后。...如图所示。我如何让它使用超过2行并显示它全部。我试过使用lineLimit，但它没有什么区别。

import SwiftUI

struct writtenpromptView: View {
    
    @State private var Prompt: String = ""

    @State var chatarray: [String] = ["Hello", "hello"]
    @State var aiarray: [String] = ["good question", "hello"]
    
    var body: some View {
        ZStack {
            Color("darkgpt")
                .edgesIgnoringSafeArea(.all)
            VStack {
                topbar()
                    .padding(.top, 35)
                    .edgesIgnoringSafeArea(.all)
                    .frame(height:45)
                    .padding(.bottom, 10)
                ScrollView {
                    ScrollViewReader { value in
                        GeometryReader { geometry in
                            VStack {
                                ForEach(0..<chatarray.count, id:\.self) { index in
                                        Rectangle()
                                        .foregroundColor(Color("darkgpt"))

                                        .overlay(Text(chatarray[index]).foregroundColor(Color("textgrey")).frame(minWidth: 50, maxWidth: geometry.size.width - 60, minHeight: 50, maxHeight: 500))
