Can't solve scroll view in SwiftUI - swift

Question

Could someone please explain to me how the ScrollView works, how can I make that when I receive a message it scrolls to the last message ( item )?
I tried to make it with a, ScrollViewReader { proxy in } but I still can't make this code work.
I tried also to make it ' .onchange(of: ) { } ' (with ScrollViewReader)
struct ContentView: View{
#ObservedObject var viewModel = ViewModel()
#State var text = ""
#State var models = [String]()
var body: some View {
VStack(alignment: .leading) {
ScrollViewReader { proxy in
ScrollView (showsIndicators: false){
ForEach(models, id: \.self){ string in
Text(string)
.font(.headline)
.padding()
.background(Color("Text"))
.cornerRadius(10)
.overlay(RoundedRectangle(cornerRadius: 10).strokeBorder(.blue, style: .init(lineWidth: 1))
)
Divider()
}
.onChange(of: models){
proxy.scrollTo(models.last)
}
}
}
Spacer()
HStack{
TextField("Type here...", text: $text)
.padding(15.0)
.padding(.horizontal)
Button(){
send()
} label: {
Image(systemName: "arrow.up.circle.fill")
.font(.system(size: 40))
.foregroundColor(Color("Button"))
}
.padding(10.0)
}
.overlay(
RoundedRectangle(cornerRadius: 100)
.stroke(Color("Stroke"), lineWidth: 1)
)
}
.onAppear{
viewModel.setup()
}
.padding()
.background(/*#START_MENU_TOKEN#*//*#PLACEHOLDER=View#*/Color("Background")/*#END_MENU_TOKEN#*/)
}
func send() {
guard !text.trimmingCharacters(in: .whitespaces).isEmpty else {
return
}
models.append("Me: \(self.text)")
viewModel.send(text: text) { response in
DispatchQueue.main.async {
self.models.append("Answer: "+response)
self.text = ""
}
}
}
}

use a different overload
proxy.scrollTo(models.last,anchor:.top)
