Reply to Why first View on my NavigationStack appears again when I switch branch?
I don't understand why the NavigationStack is still in the view lifecycle when I tap on the "End" button in the last step and toggle the isFinished state. Here, the NavigationStack should not exist anymore because it's in another branch conditioned by the isFinished flag. And I don't understand why you say the NavigationStack has nothing to display at the end of the onboarding. The path still contains the steps (now that i don't remove them from the path when tapping on "End").

Reply to Why first View on my NavigationStack appears again when I switch branch?
Thanks @darkpaw. I moved the .onAppear { print("onAppear: start") } to the Text("Start"). The result is the same. I also removed the line that removes the steps in the "End" button action, and moved it to the "Restart" button. The result is the same. In this case, the NavigationStack should not pop back to its initial view (the VStack), so I still don't get why this NavigationStack root view appears again.

Reply to Importing Data into SwiftData in the Background Using ModelActor and @Query
@DTS Engineer this issue is still in Xcode 16.2 iOS 18.2 beta 1. I don't understand how this major bug is still not fixed by now... Can someone at Apple seriously look into this bug? Also, instead of observing the NSManagedObjectContextDidSave notification (which is part of Core Data + NSManagedObjectContext), we can observe the ModelContext didSave notification. The userInfo dictionary contains the PersistentIdentifiers of inserted/updated/deleted models, so we can only update views using changed models. extension NotificationCenter { var modelContextDidSavePublisher: Publishers.ReceiveOn<NotificationCenter.Publisher, DispatchQueue> { return publisher(for: ModelContext.didSave, object: nil).receive(on: DispatchQueue.main) } } Documentation: https://developer.apple.com/documentation/swiftdata/modelcontext/didsave

Reply to Automatic Grammar Agreement with formatted number: use integer value to switch categories
I realised I can use Morphology to specify the GrammaticalNumber based on the count value like this private var formattedAttributedString: AttributedString { let formattedCount: String = numberFormatter.string(from: count as NSNumber)! var string: AttributedString = AttributedString(localized: "key_with_string_\(formattedCount)") var morphology = Morphology() let number: Morphology.GrammaticalNumber switch count { case 0: number = .zero case 1: number = .singular case 2: number = .pluralTwo default: number = .plural } morphology.number = number string.inflect = InflectionRule(morphology: morphology) let formattedResult: AttributedString = string.inflected() return formattedResult } This provides the correct string. But I'm not sure this is the correct way to do it because I have to manually specify the morphology.number (I guess .pluralFew and .pluralMany depends on the language). Is there a better solution?

Reply to Are Deep Links on Custom Product Pages working?
Thanks @App Store Connect Engineer for answering. So it means that if someone downloads an app from a Product Page, leaves the store, then opens the app from the device (home screen for example), the deep link does not work? If this is the case, this is really sad because it makes this feature weak. The OS should keep in cache the original product page used to download the app. I filed a feedback for that: FB13991558

Reply to How does listSectionSpacing works in SwiftUI?
Thanks @DTS Engineer for exploring with me! Before posting my first question, I initially thought I found the value that was used between sections. It seems that spacingBeforeN = min(spacing[n] / 2 + spacing[n-1]/2, 35.33) So this would mean the spacing is capped to a maximum value (the default spacing?). And the documentation is wrong (it's not the minimum spacing that is used). But it does not explain how it works with header and/or footer. As previously shared, when I enable a header and/or footer, the spacing doesn't seem to be used.

Reply to How does listSectionSpacing works in SwiftUI?
Thanks @DTS Engineer Sydney for answering. The documentation in Xcode 16 clearly states that it's possible to apply different spacing. It's probably new to iOS 18 (and other OSes), but it seems buggy unfortunately. Can you make sure the feedback I mentioned in my previous post (https://feedbackassistant.apple.com/feedback/13699952) will be taken into consideration?

Reply to SwiftUI: detect the beginning of a View using scrollPosition in a V/HStack
Thanks for your answer. Unfortunately, I'm not sure how to interpret it. Maybe my question was not clear enough and I badly explained what I want. I don't want to only detect the top of the red Text("0") view (i.e. the top of the scrollView), I want to detect the top/bottom of every red Text("...") view, without the spacing being taken into account. So when scrolling down, I want the binding to be updated only when a red background is at the top of the visible scroll view. In the example I provide, the binding is updated to 5 soon after I scroll 4, where 5 is at the middle of the screen. And when scrolling down, I want the binding to be updated only when a red background appears at the top. In my example, the binding is updated to 8 when 9 is still almost at the top of the screen. The thing I find strange is that setting the binding to 7 scroll at the position I want: just over the red Text("7") view. As if this was considered the top of a target View. Why scrolling provides a different result? Why would the spacing or margin be taken into account when scrolling but not when specifying manually a position?

Reply to NavigationSplitView crashes if I select an item in the sidebar after I removed other items
I realized the issue is actually caused by the use of Section. If I keep my same code I shared but remove the sections in the sidebar List, I don’t have the issue anymore. If I keep at least one section, it crashes. List(selection: $selectionString) { NavigationLink(value: SelectionString.all) { Text("All") } ForEach(strings.sorted(), id: \.self) { string in NavigationLink(value: SelectionString.item(string)) { Text(string) } } }

Reply to NavigationSplitView crashes if I select an item in the sidebar after I removed other items
Here is the code to reproduce the issue: import SwiftUI @main struct FB_SwiftUI_NavigationSplitView_Delete_SelectApp: App { var body: some Scene { WindowGroup { ContentView() } } } enum SelectionString: Hashable { case all case item(String) } struct ContentView: View { @State private var selectionString: SelectionString? @State private var strings: [String] = [] var body: some View { NavigationSplitView { List(selection: $selectionString) { Section { NavigationLink(value: SelectionString.all) { Text("All") } } Section { ForEach(strings.sorted(), id: \.self) { string in NavigationLink(value: SelectionString.item(string)) { Text(string) } } } } .toolbar { ToolbarItem { Button("Add") { strings.append(UUID().uuidString) } } } } detail: { if let selectionString { switch selectionString { case .all: Text("All") case .item(let string): Button(role: .destructive) { if let index = strings.firstIndex(of: string) { strings.remove(at: index) self.selectionString = nil } } label: { Text("Delete") } } } else { Text("Select an item") } } } }
