What textfield / view to show and edit text in SwiftUI? - ios

Question

I would like to edit an item, for example, I have an item named "Jacket", then I would like to edit with a new name "Gray Jacket"
Now I'll have the list of my items, and when I press the "Jacket" item, it will go to the DetailItem and when it appears, I want that textfield / view already filled with "Jacket" text then I able to edit it. Please note I want to use real text not placeholder when the item name first shows up.
Does anyone know what element should I use, or if textfield how? Because I couldn't find how to set textfield with name when it first appears.
UPDATE:
Here's what I've tried, this code I took it from here. It basically took the previous text and make it a placeholder, while actually I want it to be editable.
struct CustomTextField: View {
var placeholder: Text
#Binding var text: String
var editingChanged: (Bool)->() = { _ in }
var commit: ()->() = { }
var body: some View {
ZStack(alignment: .leading) {
if text.isEmpty { placeholder }
TextField("", text: $text, onEditingChanged: editingChanged, onCommit: commit)
}
}
}
struct UsageCustomTxtField: View {
#State var text = ""
var body: some View {
CustomTextField(
placeholder: Text("placeholder").foregroundColor(.black),
text: $text
)
}
}

Here is a possible solution:
import SwiftUI
struct ContentView: View {
#ObservedObject var myItems: ItemViewModel = ItemViewModel()
#State var myNewName: String = "" // Will set the new name
var body: some View {
VStack {
TextField(self.myItems.myList[0].name, // when it appears, I want that textfield / view already filled with "Jacket" text
text: self.$myNewName,
onCommit: {
self.myItems.changeNameOfListItemTo(newName: self.myNewName, index: 0) I would like to edit with a new name "Gray Jacket"
self.myNewName = "" //empty the textfield again so name from item itself will be displayed
})
}
}
}
struct Item { // I have an item named "Jacket"
var name: String
init(name: String) {
self.name = name
}
}
class ItemViewModel: ObservableObject {
#Published var myList: Array<Item> = [Item(name: "Jacket")] //your item list
func changeNameOfListItemTo(newName: String, index: Int) { //function to change the name of an item
self.myList[0].name = newName
}
}
