I want to create an auto-scrollable text. When the content grows longer, it can automatically scroll to the bottom and show the last line. Here is my code: struct ContentView: View {   @State var text = "Hello everyone: "   @State var index = 0       var body: some View {     VStack {       ScrollViewReader { reader in         ScrollView {           VStack {             Text(text)               .font(.title)               .id("textId")               .padding(10)           }         }         .frame(width: 300, height: 160, alignment: .topLeading)         .border(.blue)         .onChange(of: text, perform: { _ in           reader.scrollTo("textId", anchor: .bottom)         })       }               Button("Append") {         index += 1         text += "Hello \(index); "       }     }   } } It only works when I scroll the text and then append new text. Can someone please help? Thank you!
