Code Block .isDetailLink(false)
Adding a NavigationLink with an empty view didn't work for me. I solved my issue removing all NavigationLinks from the ForEach and using a single one to control the navigation to the detail view, a tap gesture and 2 state variables to keep track on what is being tapped on.
The example broken code and fix can be found at Paul Hudson's site.

Below is the complete working version
import SwiftUI
struct NavigationViewOptions {
enum OptionType { case main, optional }
typealias Option = (id: UUID, value: String, type: Self.OptionType)
static var options: [Option] = [
(UUID(), "Option 1", .main),
(UUID(), "Option 2", .optional),
(UUID(), "Option 3", .main),
(UUID(), "Option 4", .main),
(UUID(), "Option 5", .optional),
]
static func buildView(for option: Option) -> some View {
switch option.type {
case .main:
return Text("Main Option selected\n\(option.value)").font(.title).fontWeight(.bold)
case .optional:
return Text("Optional Option selected\n\(option.value)").font(.title3).italic().fontWeight(.medium)
}
}
}
struct NavigationViewWorking: View {
// State variables to leep track of what option has been tapped on and when to navigate to new view
@State private var selectedOption: NavigationViewOptions.Option = (id:UUID(),"",.main)
@State private var showDetail: Bool = false
var body: some View {
NavigationView {
ScrollView{
VStack (alignment:.leading) {
Text("NAVIGATION FIX FOR:\nUnable to present. Please file a bug.")
.padding(.bottom, 40)
ForEach(NavigationViewOptions.options, id: \.id) { option in
Text(option.value)
.font(.title)
.padding(.vertical, 10)
.foregroundColor(.accentColor) // same color as navigationLink
// handle tap on option
.onTapGesture {
selectedOption = option
showDetail = true
}
}
Spacer()
NavigationLink("", destination: NavigationViewOptions.buildView(for: selectedOption), isActive: $showDetail)
.opacity(0)
}
.navigationTitle("Options")
}
// INITIAL DETAIL VIEW
Text("Select option from the left")
}
}
}
@hower your solution basically works, but in this way onAppear on destination view it's called just once. I'm downloading detail content in onAppear in the destination view, how this could be handled?
