How to get textField values in the list swiftui - ios

Question

I used the list this way
I want to send all TextField values when the submit button is clicked.
My problem is that I can't get the TextField value in the list
I also use mvvm architecture in the project
my code in the project :
My Model :
import Foundation
import SwiftUI
struct MyModel : Identifiable {
var id:Int64
var title:String
#State var value:String
}
My ViewModel :
import Foundation
import SwiftUI
class MyViewModel: ObservableObject {
#Published var items:[MyModel] = []
init() {
populateItem()
}
func populateItem(){
self.items.append(MyModel(id: 0, title: "title #1", value: ""))
self.items.append(MyModel(id: 1, title: "title #2", value: ""))
self.items.append(MyModel(id: 2, title: "title #3", value: ""))
self.items.append(MyModel(id: 3, title: "title #4", value: ""))
self.items.append(MyModel(id: 4, title: "title #5", value: ""))
self.items.append(MyModel(id: 5, title: "title #6", value: ""))
}
}
My View :
import SwiftUI
struct ContentView: View {
#ObservedObject var myViewModel = MyViewModel()
var body: some View {
VStack {
List {
ForEach(self.myViewModel.items) {item in
HStack {
Text(item.title)
TextField("value", text: item.$value)
}
}
}
Button(action: {
print(self.myViewModel.items[0].value)
}){
Text("Submit")
}.padding()
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}

First remove #State property wrapper from your model's value property.
And update your ForEach with the next code:
ForEach(self.myViewModel.items.indices, id:\.self) { index in
HStack {
Text(self.myViewModel.items[index].title)
TextField("value", text: Binding(
get: {
return self.myViewModel.items[index].value
},
set: { newValue in
return self.myViewModel.items[index].value = newValue
}))
}
}
