Adding an Import... menu item using .commands{CommandGroup... on DocumentGroup( ... ) { ContentView() } .commands { CommandGroup(replacing: .importExport) { Button("Import…") { isImporting = true } .keyboardShortcut("I", modifiers: .option) .fileImporter( isPresented: $isImporting, allowedContentTypes: [.commaSeparatedText], allowsMultipleSelection: false ) { result in switch result { case .success(let urls): print("File import success") ImportCSV.importCSV(url: urls, in: context) // This is the issue case .failure(let error): print("File import error: \(error)") } } } I could get this to work if I were not using DocumentGroup but instead programmatically creating the modelContext. using the shared modelContext in ImportCSV is not possible since that is not a View passing the context as shown above would work if I knew how to get the modelContext but does it even exist yet in Main? Is this the right place to put the commands code? Perhaps the best thing is to have a view appear on import, then used the shared modelContext. In Xcode menu File/Add Package Dependencies... opens a popup. How is that done?

DESCRIPTION OF PROBLEM When my Document-based macOS SwiftUI app starts up, it always presents a document picker. I would like it to open any documents that were open when the app last quit, and if none were open, open an "Untitled" document. I understand that there is a setting in System Settings-> Desktop & Dock ("Close windows when quitting an application") that will cause windows to reopen when it is turned off, but I'd like to give users a chance to opt-in for reopening docs even when that is turned on, since it is difficult to find, on by default, and might not be the desired behavior for all apps. I don't see any way to get a list of currently open documents to persist them at shutdown. And even if that's considered a bad idea, I'd at least like a way to prevent the Document picker from being shown at startup and instead create an Untitled document if no documents were open. Ideally, I'd like a way to provide this functionality in SwiftUI that doesn't require macOS 15 or later STEPS TO REPRODUCE Create a SwiftUI macOS document application in Xcode using the provided template, Give it any name you want Run it, create a new ".exampletext" document, save it. Quit the app with the document open. Re-run the app, document picker is shown. Cancel the document picker and quit the app with no windows shown. Re-run the app, document picker is shown.

Hello i ve implemented progressview and updating the state via push notification. the progress view wants closedrange which i followed but whenever i get update, the progress value resets to beginning my range is like : Date.now..endDate but i dont get it, lets assume that i get the date from database and initialized already then how the code will understand that what progress value will be as current ? it has to be something like i suppose : startDate..Date.now..endDate thanks

Hi, would anyone be so kind and try to guide me, which technologies, Kits, APIs, approaches etc. are useful for creating a horizontal window with map (preferrably MapKit) on visionOS using SwiftUI? I was hoping to achieve scenario: User can walk around and interact with horizontal map window and also interact with (3D) pins on the map. Similar thing was done by SAP in their "SAP Analytics Cloud" app (second image from top). Since I am complete beginner in this area, I was looking for a clean, simple solution. I need to know, if AR/RealityKit is necessary or is this achievable only using native SwiftUI? I tried using just Map() with .rotation3DEffect() which actually makes the map horizontal, but gestures on the map are out of sync and I really dont know, if this approach is valid or complete rubbish. Any feedback appreciated.

I am working on the device activity report. and fetched data is loading on the chart. I am developing app using TabbarController. when I go to another tab and come back to the chart screen, it disappears. Here, I am working on a storyboard using Swift language, and device activity reports can be fetched only with SwiftUI. So, the problem is with it? Following the current code. @State private var context: DeviceActivityReport.Context = .init(rawValue: "Daily Activity") @State private var report: DeviceActivityReport? @State private var filter = DeviceActivityFilter( segment: .daily( during: Calendar.current.dateInterval( of: .day, for: .now )! ) // users: .all // devices: .init([.iPhone, .iPad]) ) @State var isReload: Bool = false var body: some View { ZStack { if isReload { LoadingView(title: "Data is loading...") } else if let report = report { report } else { DeviceActivityReport(context, filter: filter) } } .onAppear { DispatchQueue.main.async { report = DeviceActivityReport(context, filter: filter) } } } struct LoadingView: View { var title: String = "Please wait..." var body: some View { HStack { ProgressView(title) .font(.system(size: 14, weight: .medium)) .progressViewStyle(.horizontal) .tint(Color(.darkGray)) .padding(8) } .background(Color(.white)) .cornerRadius(8) .clipped() } }

I have an old Objective-C app that has been running for several years. The last compilation was in February 2024. I just upgraded to Sequoia 15.1. The app has four subviews on its main view. When I run the app only the subview that was the last one instantiated is visible. I know the other subviews are there, because a random mouse click in one invisible view causes the expected change in the visible view. What changed in 15.1 to cause this?

When I upgraded to Sequoia 15.1, an app that worked fine under OS 14 stopped working. Out of 4 views on the main screen, only 1 is visible. Yet, if I click where another view should be, I get the expected action so the views are there, just not visible. Only I can't see where I am clicking! I had to upgrade to Xcode 16 to recompile the app and run it in Debug mode. When I do, I get the following: NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed. Can't find or decode disabled use cases. applicationSupportsSecureRestorableState FWIW - the only view that actually shows up is the last subview added to the main view.

So I'm following this code here where I'm using a tableview to display the files contained in a folder along with a group cell to display the name of the current folder: Here's my tableView:isGroupRow method: method which basically turns every row with the folder name into a group row (which is displayed in red in the previous image ). -(BOOL)tableView:(NSTableView *)tableView isGroupRow:(NSInteger)row { DesktopEntity *entity = _tableContents[row]; if ([entity isKindOfClass:[DesktopFolderEntity class]]) { return YES; } return NO; } and here's my tableView:viewForTableColumn:row: method where I have two if statements to decide whether the current row is a group row (meaning it's a folder) or an image: -(NSView*)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row; { DesktopEntity *entity = _tableContents[row]; if ([entity isKindOfClass:[DesktopFolderEntity class]]) { NSTextField *groupCell = [tableView makeViewWithIdentifier:@"GroupCell" owner:self]; [groupCell setStringValue: entity.name]; [groupCell setFont:[NSFont fontWithName:@"Arial" size:40]]; [groupCell setTextColor:[NSColor magentaColor]]; return groupCell; } else if ([entity isKindOfClass:[DesktopImageEntity class]]) { NSTableCellView *cellView = [tableView makeViewWithIdentifier:@"ImageCell" owner:self]; [cellView.textField setStringValue: entity.name]; [cellView.textField setFont:[NSFont fontWithName:@"Impact" size:20]]; [cellView.imageView setImage: [(DesktopImageEntity *)entity image]]; return cellView; } return nil; } Now, if the current row is an image, I change its font to Impact with a size of 40 and that works perfectly, the problem here is with the first IF statement, for a group row I wanted to change the font size to arial with a size of 40 with a magenta color but for some reason I can only get the color to work: You can see that my changes to the font size didn't work here, what gives? How can I change the font size for the group row ?

I am working on a scrollable chart that displays days on the horizontal axis. As the user scrolls, I always want them to be able to snap to a specific day. I implemented the following steps described in this WWDC23 session to achieve this. I have set the chartScrollTargetBehavior to .valueAligned(matching: DateComponents(hour: 0)) I have set the x value unit on the BarMark to Calendar.Component.day I ended up with the chart code that looks like this: Chart(dates, id: \.self) { date in BarMark( x: .value("Date", date, unit: Calendar.Component.day), y: .value("Number", 1) ) .annotation { Text(date.formatted(.dateTime.day())) .font(.caption2) } } .chartXAxis { AxisMarks(format: .dateTime.day()) } .chartScrollableAxes(.horizontal) .chartScrollTargetBehavior(.valueAligned(matching: DateComponents(hour: 0))) .chartXVisibleDomain(length: fifteenDays) .chartScrollPosition(x: $selection) However, this fails to work reliably. There is often a situation where the chart scroll position lands on, for instance, Oct 20, 11:56 PM, but the chart snaps to Oct 21. I attempted to solve this problem by introducing an intermediate binding between a state value and a chart selection. This binding aims to normalize the selection always to be the first moment of any given date. But this hasn't been successful. private var selectionBinding: Binding<Date> { Binding { Calendar.current.startOfDay(for: selection) } set: { newValue in self.selection = Calendar.current.startOfDay(for: newValue) } } It's also worth mentioning that this issue also exists in Apple's sample project on Swift Charts. How would you approach solving this? How can I find a way to make the chart scroll position blind to time values and only recognize whole days? Here's the minimal reproducible example project for your reference.

I am trying to get my head around how to implement a MapKit view using UIViewRepresentable (I want the map to rotate to align with heading, which Map() can't handle yet to my knowledge). I am also playing with making my LocationManager an Actor and setting up a listener. But when combined with UIViewRepresentable this seems to create a rather convoluted data flow since the @State var of the vm needs to then be passed and bound in the UIViewRepresentable. And the listener having this for await location in await lm.$lastLocation.values seems at least like a code smell. That double await just feels wrong. But I am also new to Swift so perhaps what I have here actually is a good approach? struct MapScreen: View { @State private var vm = ViewModel() var body: some View { VStack { MapView(vm: $vm) } .task { vm.startWalk() } } } extension MapScreen { @Observable final class ViewModel { private var lm = LocationManager() private var listenerTask: Task&lt;Void, Never&gt;? var course: Double = 0.0 var location: CLLocation? func startWalk() { Task { await lm.startLocationUpdates() } listenerTask = Task { for await location in await lm.$lastLocation.values { await MainActor.run { if let location { withAnimation { self.location = location self.course = location.course } } } } } Logger.map.info("started Walk") } } struct MapView: UIViewRepresentable { @Binding var vm: ViewModel func makeCoordinator() -&gt; Coordinator { Coordinator(parent: self) } func makeUIView(context: Context) -&gt; MKMapView { let view = MKMapView() view.delegate = context.coordinator view.preferredConfiguration = MKHybridMapConfiguration() return view } func updateUIView(_ view: MKMapView, context: Context) { context.coordinator.parent = self if let coordinate = vm.location?.coordinate { if view.centerCoordinate != coordinate { view.centerCoordinate = coordinate } } } } class Coordinator: NSObject, MKMapViewDelegate { var parent: MapView init(parent: MapView) { self.parent = parent } } } actor LocationManager{ private let clManager = CLLocationManager() private(set) var isAuthorized: Bool = false private var backgroundActivity: CLBackgroundActivitySession? private var updateTask: Task&lt;Void, Never&gt;? @Published var lastLocation: CLLocation? func startLocationUpdates() { updateTask = Task { do { backgroundActivity = CLBackgroundActivitySession() let updates = CLLocationUpdate.liveUpdates() for try await update in updates { if let location = update.location { lastLocation = location } } } catch { Logger.location.error("\(error.localizedDescription)") } } } func stopLocationUpdates() { updateTask?.cancel() updateTask = nil } func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { switch clManager.authorizationStatus { case .authorizedAlways, .authorizedWhenInUse: isAuthorized = true // clManager.requestLocation() // ?? case .notDetermined: isAuthorized = false clManager.requestWhenInUseAuthorization() case .denied: isAuthorized = false Logger.location.error("Access Denied") case .restricted: Logger.location.error("Access Restricted") @unknown default: let statusString = clManager.authorizationStatus.rawValue Logger.location.warning("Unknown Access status not handled: \(statusString)") } } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { Logger.location.error("\(error.localizedDescription)") } }

Hi all, I’ve been facing a behavior issue with shouldAutomaticallyForwardAppearanceMethods in UITabBarController. According to Apple’s documentation, this property should default to YES, which means that the appearance lifecycle methods (like viewWillAppear and viewDidAppear) should be automatically forwarded to child view controllers. However, in my current development environment, I’ve noticed that shouldAutomaticallyForwardAppearanceMethods returns NO by default in UITabBarController, and this is causing some issues with lifecycle management in my app. I even tested this behavior in several projects, both in Swift and Objective-C, and the result is consistent. Here are some details about my setup: I’m using Xcode 16.0 with iOS 16.4 Simulator. I’ve tested the behavior in both a new UIKit project and a simple SwiftUI project that uses a UITabBarController. Even with a clean new project, the value of shouldAutomaticallyForwardAppearanceMethods is NO by default. This behavior contradicts the official documentation, which states that it should be YES by default. Could someone clarify if this is expected behavior in newer versions of iOS or if there is a known issue regarding this? Any help or clarification would be greatly appreciated! Thanks in advance!

why do I need to set the font of an image of an SF symbol to get the effect to work? This should be a bug, it's bad behavior. Xcode 16.1 iOS 18.1, so frustrating. for example: this works Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .symbolEffect(.rotate, options: .repeat(.continuous), value: isActive) .font(.largeTitle) .onAppear() { isActive = true } but this does not animate, which makes no sense Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .symbolEffect(.rotate, options: .repeat(.continuous), value: isActive) .onAppear() { isActive = true } its the same if you use a simple setup and different font size, and whether font is before or after the symbol effect Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .font(.headline) // only works if this line is here .symbolEffect(.rotate, options: .repeat(.continuous))

DeviceActivityReport presents statistics for a device: https://developer.apple.com/documentation/deviceactivity/deviceactivityreport The problem: DeviceActivityReport can present statistics with a delay for a parent device (when DeviceActivityReport is presenting, the DeviceActivityReportExtension is called to process the statistics). One possible solution is to call DeviceActivityReport periodically throughout the day in a child device. However, the app will not be available all day. Is there any way to run DeviceActivityReport in the background? I have tried the following approach, but it didn’t work (DeviceActivityReportExtension didnt call): let hostingController: UIHostingController? = .init(rootView: DeviceActivityReport(context, filter: filter)) hostingController?.view.frame = .init(origin: .zero, size: .init(width: 100, height: 100)) hostingController?.beginAppearanceTransition(true, animated: false) hostingController?.loadView() hostingController?.viewDidLoad() try? await Task.sleep(for: .seconds(0.5)) hostingController?.viewWillAppear(true) hostingController?.viewWillLayoutSubviews() try? await Task.sleep(for: .seconds(0.5)) hostingController?.viewDidAppear(true) try? await Task.sleep(for: .seconds(0.5)) hostingController?.didMove(toParent: rootVC) try? await Task.sleep(for: .seconds(0.5)) hostingController?.viewWillLayoutSubviews() hostingController?.viewDidLayoutSubviews() hostingController?.view.layoutIfNeeded() hostingController?.view.layoutSubviews() hostingController?.endAppearanceTransition() Is there any way to run DeviceActivityReport in the background? (when app is not visible/closed). The main problem is call DeviceActivityReport

I have a Split View with the sidebar, content, and detail. Everything is working, but when I select on a NavigationLink in my detail view, the back button is seen next to the title above the content view. I want that back button to be displayed in the top bar on the left side of the detail view. I was expecting it to do this automatically, but I must be missing something. This is where I want it to appear. This is where it appears. I made a simplified version of my code, because it would be too much to post but this has the same behavior. struct TestView: View { enum SidebarSelections { case cycles } @State private var sidebarSelection: SidebarSelections = .cycles var body: some View { NavigationSplitView(sidebar: { List(selection: $sidebarSelection, content: { Label("Cycles", systemImage: "calendar") .tag(SidebarSelections.cycles) }) }, content: { switch sidebarSelection { case .cycles: NavigationStack { List { // Displayed in Content NavigationLink("Cycle link", destination: { // Displayed in the Detail NavigationStack { List { NavigationLink("Detail Link", destination: { Text("More details") }) } } }) } } } }, detail: { ContentUnavailableView("Nothing to see here", systemImage: "cloud") }) } } Is what I want to do possible? Here is a Stack Overflow post that had it working at one point.

I'd like to use ScrollViewReader, but on a list of static text that has formatting such as font colors and bold text. Essentially, my list has a bunch of: Text("some text ") + Text(" and more text").fontWeight(.bold).foregroundStyle(boldColor) Switching to AttributedString would be a pain, and I'm not so sure ScrollViewReader is working correctly. It seems like there are a lot of bugs reports about it. Plus, do we really need a separate string format, just to have proper formatting? Really? Is there another version I'm missing? One that can scroll to anchor points that I could set?

When using a NavigationSplitView within a NavigationStack, the NavigationSplitView does not work as expected on iOS 18 (it worked previously). Items do not show their associated detail views when selected. See the following minimum reproducible example: import SwiftUI struct ContentView: View { @State var selectedItem: String? = nil @State var navigationState: NavigationState? = nil var body: some View { NavigationStack { List(selection: self.$selectedItem) { NavigationLink("Item 1", value: "item") } .navigationDestination(item: self.$selectedItem) { value in ChildView() } } } } enum NavigationState: Hashable { case general case secondary } struct ChildView: View { @State var navigationState: NavigationState? = nil var body: some View { NavigationSplitView { List(selection: self.$navigationState) { NavigationLink(value: NavigationState.general) { Text("Basic info") } NavigationLink(value: NavigationState.secondary) { Text("Secondary info") } } } detail: { if self.navigationState == nil { Text("Nothing") } else { Text("Details") } } } }

First post here! Is there a way to reduce the number of haptic feedback for double tap on primary button? Context: Double tap is awesome. Two haptic actuations are given to the gesture to let the user know that the gesture is "received" then a third haptic feedback is given shortly after to signal the primary button is tapped. Is there a way to disable the third haptic feedback. In other words make primary action "silent"? I have tested a number of apps that supports double tap, it seems to me that the triple tap is a system level default, and it cannot be changed. Any help would be greatly appreciated.

I have the following lines of code where I show a bunch of checkboxes, each of which can toggle between on and off with a tap. import SwiftUI struct ContentView: View { @State private var viewModel = ContentViewModel() var body: some View { VStack(alignment: .leading) { List { ForEach(viewModel.models, id: \.id) { model in CheckButtonView(id: model.id, text: model.name, isOn: model.isOn) { id, bool in updateDate(id: id, bool: bool) } } } } } func updateDate(id: String, bool: Bool) { for i in 0..<viewModel.models.count { let oldModel = viewModel.models[i] if oldModel.id == id { let newModel = Content(id: oldModel.id, name: oldModel.name, isOn: bool) viewModel.models.remove(at: i) viewModel.models.insert(newModel, at: i) break } } var count = 0 for i in 0..<viewModel.models.count { let model = viewModel.models[i] if model.isOn { count += 1 } } } } struct CheckButtonView: View { let id: String let text: String @State var isOn: Bool var callBack: (String, Bool) -> Void var body: some View { HStack { Button { isOn.toggle() callBack(id, isOn) } label: { Image(systemName: isOn ? "checkmark.square.fill" : "square") .resizable() .aspectRatio(contentMode: .fit) .frame(width: 18) .tint(!isOn ? .black : .blue) } Text(text) .font(.subheadline) Spacer() } .frame(maxWidth: .infinity) } } struct Content { let id: String let name: String let isOn: Bool } class ContentViewModel: ObservableObject { @Published var models = [Content]() @Published var canChange = true init() { models = [ Content(id: UUID().uuidString, name: "Jim", isOn: false), Content(id: UUID().uuidString, name: "Jenny", isOn: false), Content(id: UUID().uuidString, name: "Nancy", isOn: false), Content(id: UUID().uuidString, name: "Natalie", isOn: false) ] } } According to the picture above, I have two checkboxes that are turned on. Now, what I want to do is let the user turn on as many as two checkboxes only. Can someone think of a good way of doing that? Thanks.

Hi, I am a new SwiftUI app developer and developing my first application. In the process of designing not very GUI rich app, I noticed my app crashed whenever I switched orientation (testing on multiple iPhone devices). After going through all kind of logs and errors, performance enhancements nothing worked. Then I started rolling back all GUI related features 1 by 1 and tested (I am sure there are better approaches, but excuse me I am novice in app development :) ). Even though it's time consuming, I could pin point the cause of the fatal error and app crash, it's due to multiple .shadow modifiers I used on NavigationLink inside a ForEach look (to be precise I used it like following, .shadow(radius: 15) .shadow(radius: 20) .shadow(radius: 20) .shadow(radius: 20) .shadow(radius: 20) Note, there are only 7 items in List and it uses the Hero View (like app store's Today section) for child views. Once I got rid of shadow modifies or used only 1 app works fine and doesn't crash. Lesson learnt... P.S. It's so ironic that so performance tuned devices couldn't handle this basic GUI stuff.

How do I scroll to a row and select it when it is part of collapsed rows in Table ScrollViewReader { scrollViewProxy in Table([node], children: \.children, selection: $selectedNodeID) { TableColumn("Key") { Text($0.key) } TableColumn("Value") { Text($0.val) } } .onChange(of: selectedNodeID) { _, newValue in withAnimation { scrollViewProxy.scrollTo(newValue) } } } The code above works well for the rows that are expanded or at the root level. However, for the rows that are not yet expanded the code above does nothing. How can I update the code so that it scrolls to a row that has not materialized yet. Info: This is a macOS app I am on macOS 15.1.1 with Xcode 16.1 and the minimum target of the app is macOS 15
