Connecting TextField to each List item in SwiftUI

Question

I'm really sorry to ask this silly question , but how do i assign the TextField to each item in the list? At the moment i understand that TextField is not connected to any of items hence when you add items and try to enter some input it's editing all the textfields at the same time. Thanks

Answer 1

Most likely you want to bind each text field to a property in Item for example description. Just delete

@State private var textField = ""

and change the List to

List($vm.itemList) { $item in
    Text(item.name)                
    TextField("Assign the value", text: $item.description)
}

Note: In this case description must be non-optional.
