Consider this complete SwiftUI macOS app
```swiftui
//
// TestSearchStringInViewModelApp.swift
// TestSearchStringInViewModel
//
// Created by Damian Mehers on 2024-01-15.
//
import SwiftUI
@main
struct TestSearchStringInViewModelApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
// using @Bindable or plain "var" with a Bindable<ViewModel> object in the code does same thing
@State var viewModel = ViewModel()
var body: some View {
NavigationSplitView {
VStack {
List(1..<5) { n in
Text("\(n)")
}
.listStyle(SidebarListStyle())
// Works if not sidebar or @State searchString
.searchable(text: $viewModel.searchString, placement: .sidebar)
}
} detail: {
Text("Some detail")
}
}
}
@Observable final class ViewModel {
var searchString = ""
}
```
When you run it, when you tap “a” into the searchbar two “a”s appear, and when they are both deleted you get a crash:
```
