Update: I have now been able to successfully reproduce the issue in a minimal app environment. See the new MyView.swift.
As the title suggests, My SwiftUI app crashes with 'NSInvalidArgumentException' only when a List cell is tapped from a search bar.
My issue is this:
I have a List that is declared .searchable, which uses a navigation link to link to another List, which is also declared .searchable. The second list bring up a modal page with .sheet The searching in the first list works fine. The second list, on the other hand, works fine if the user apps a row without searching. However, if the user searches in the search box, and then taps one of the filtered results, the app presents the modal page and loads everything, then crashes.
If I remove the NavigationView from the popup, then the app no longer crashes. However, then the search bar from the view behind it carries on to the popup which I do not want.
Here is the error message from the console:

Steps To Reproduce:
- Get sample code provide below
- Run the app
- Tap an item in the first list
- Search "1" in the search box in the next list
- Tap the first result
- The app should crash

Here is a sample app in which I was able to replicate the behavior.
Test_AppApp.swift:
import SwiftUI
@main
struct Test_AppApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
ContentView.swift:
import SwiftUI
struct ContentView: View {
@State var sheetIsPresented:Bool = false
@State var searchText:String = ""
struct item: Identifiable {
var id:String
var string:String
}
func getItems() -> Array<item> {
let items = ["Item 1", "Item 2", "Item 3", "Item 4"].map({ item(id: UUID().uuidString, string: $0) })
if searchText == "" {
return items
} else {
return items.filter({ $0.string.contains(searchText) })
}
}
var body: some View {
NavigationView {
List {
ForEach(getItems()) { item in
NavigationLink(item.string) {
NextView()
}
}
/*
.onDelete { index in
print("delete")
}
*/
}
.searchable(text: $searchText)
.navigationTitle("Test App")
.navigationBarTitleDisplayMode(.large)
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
NextView.swift:
import SwiftUI
struct NextView: View {
@State var sheetIsPresented:Bool = false
@State var searchText:String = ""
struct item: Identifiable {
var id:String
var string:String
}
func getItems() -> Array<item> {
let items = ["Item 1", "Item 2", "Item 3", "Item 4"].map({ item(id: UUID().uuidString, string: $0) })
if searchText == "" {
return items
} else {
return items.filter({ $0.string.contains(searchText) })
}
}
var body: some View {
List {
ForEach(getItems()) { item in
HStack {
Button {
sheetIsPresented = true
} label: {
HStack {
Image(systemName: "shippingbox")
Text(item.string)
.foregroundColor(Color.black)
}
}
.sheet(isPresented: $sheetIsPresented, content: {
MyView()
})
}
}
/*
.onDelete { index in
print("delete")
}
*/
}
.searchable(text: $searchText)
.navigationTitle("Test App")
}
}
struct NextView_Previews: PreviewProvider {
static var previews: some View {
NextView()
}
}
MyView.swift:
import SwiftUI
struct MyView: View {
var body: some View {
NavigationView {
List {
Text("Test")
}
}
.navigationBarTitle("Test Page")
}
}
struct MyView_Previews: PreviewProvider {
static var previews: some View {
MyView()
}
}
