Hi ,
I was watching
https://developer.apple.com/videos/play/wwdc2020/10148/
And I did read the demo project code
but I don't understand how Apple know when write "W" in textfield it's "W" in drawing area ?
I understand that we separate every char from drawing data , but how it matching with the textfield text ?
this part it's confusing me

I have tried apple example
Bringing robust navigation structure to your SwiftUI app
so my code looks like this
NavigationSplitView(
columnVisibility: $navigationModel.columnVisibility
) {
List(
categories,
selection: $navigationModel.selectedCategory
) { category in
NavigationLink(category.localizedName, value: category)
}
.navigationTitle("Categories")
.toolbar {
ExperienceButton(isActive: $showExperiencePicker)
}
} detail: {
NavigationStack(path: $navigationModel.recipePath) {
RecipeGrid(category: navigationModel.selectedCategory)
}
}
Details View
struct RecipeGrid: View {
var category: Category?
var dataModel = DataModel.shared
var body: some View {
ZStack {
if let category = category {
ScrollView {
LazyVGrid(columns: columns) {
ForEach(dataModel.recipes(in: category)) { recipe in
NavigationLink(value: recipe) {
RecipeTile(recipe: recipe)
}
.buttonStyle(.plain)
}
}
.padding()
}
.navigationTitle(category.localizedName)
.navigationDestination(for: Recipe.self) { recipe in
RecipeDetail(recipe: recipe) { relatedRecipe in
NavigationLink(value: relatedRecipe) {
RecipeTile(recipe: relatedRecipe)
}
.buttonStyle(.plain)
}
}
} else {
Text("Choose a category")
.navigationTitle("")
}
}
}
var columns: [GridItem] {
[ GridItem(.adaptive(minimum: 240)) ]
}
}
My issue is if I go to details view then tap on other sidebar item
after that return to same tap, it will return to rootview also onAppear it toggled!
that mean the view did rebuild itself

on Apple News app it will stay on save view
it won't rebuild or return to rootview when I change sidebar item
watch this the video]
