My team is developing an enterprise VPN application that needs to respond to Mobile Device Management (MDM) profile installations and removals in real-time. Our app uses the NetworkExtension framework and needs to update the UI immediately when VPN configurations are added or removed via MDM. We are currently observing NEVPNConfigurationChangeNotification to detect VPN configuration changes: While NEVPNConfigurationChangeNotification fires reliably when users manually remove VPN profiles through Settings > General > VPN & Device Management, it appears to have inconsistent behavior when MDM profiles containing VPN configurations are installed programmatically via MDM systems. STEPS TO REPRODUCE From MDM Admin Console: Deploy a new VPN profile to the test device On Device: Wait for MDM profile installation (usually silent, no user interaction required) Check Device Settings: Go to Settings > General > VPN & Device Management to confirm profile is installed Return to App: Check if the UI shows the new VPN profile

In an NSTableView (Appkit), I need to colour a cell background when it is selected. That works OK, except that the colour does not span the full cell width, nor even the text itself: The tableView structure is very basic: I see there is a TextCell at the end that cannot be deleted. What is this ? And the colouring as well: func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? { let p = someDataSource[row] if let cellView = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier(rawValue: "Cell"), owner: self) { (cellView as! NSTableCellView).textField?.stringValue = p if selected[row] { (cellView as! NSTableCellView).backgroundColor = theLightBlueColor } else { (cellView as! NSTableCellView).backgroundColor = .clear } return cellView } } I've tried to change size constraints in many ways, to no avail. For instance, I changed Layout to Autoresising : I tried to change TableCellView size to 170 vs 144: Or increase tableColum Width. I have looked at what other object in the NSTableView hierarchy should be coloured without success. Nothing works. What am I missing ?

Hello every developers. I need your help. Do you know how to attach animation to appearance, like a smooth transition from dark to light and vise versa. My code here: @main struct The_Library_of_BabelonApp: App { @AppStorage("selectedAppearance") private var selectedAppearance = 0 @StateObject private var router = AppRouter() var scheme: ColorScheme? { if selectedAppearance == 1 { return .light } if selectedAppearance == 2 { return .dark } return nil } var body: some Scene { WindowGroup { RootView() .preferredColorScheme(scheme) .environmentObject(router) // this is doesn't work correctly .animation(.smooth(duration: 2), value: selectedAppearance) } } } And my appearance switching looks: struct SettingsView: View { @AppStorage("selectedAppearance") private var selectedAppearance = 0 var body: some View { List { Section(header: Text("Appearance")) { HStack(spacing: 20) { ThemePreview(title: "Light", imageName: "lightTheme", tag: 1, selection: $selectedAppearance) ThemePreview(title: "Dark", imageName: "darkTheme", tag: 2, selection: $selectedAppearance) ThemePreview(title: "System", imageName: "systemMode", tag: 0, selection: $selectedAppearance) } .padding(.vertical, 10) .frame(maxWidth: .infinity) } } } } struct ThemePreview: View { let title: String let imageName: String let tag: Int @Binding var selection: Int var body: some View { Button { selection = tag } label: { VStack { Image(imageName) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 120, height: 80) .clipShape(RoundedRectangle(cornerRadius: 12)) .overlay( RoundedRectangle(cornerRadius: 12) .stroke(selection == tag ? Color.blue : Color.clear, lineWidth: 3) ) Text(title) .font(.caption) .foregroundColor(selection == tag ? .blue : .primary) } } .buttonStyle(.plain) } } I guess my code works but animation working another way, its turn my Section, I don't know.... Thank you in advance

When inputting data within a sheet, I'm allowing the user to take a photo, so the camera is called and presents itself within a 2nd sheet, however the controls are centered within the iPhone's entire screen, cropping the top controls and not extending down to the bottom of the phone's screen. Any help on how to fix this?

I am developing an iOS App for a Bluetooth peripheral using SwiftUI with Swift 5 or 6. I have a few past attempts that got so far (connected to a peripheral), and some downloaded examples that connect to peripherals. Lately (last month or so), my current attempt never gets BleManager to start, and every attempt ends at my View that says 'please enable Bluetooth'. The Xcode console is totally blank with no print outputs. Coding Assistant suggested the init() in my @main structure could contain print("App initializing"), but even that never prints. Coding Assistant suggests: "• Open your project's Info.plist in Xcode. • Make sure UIApplicationSceneManifest is present and configured for SwiftUI, not referencing any storyboard. • Ensure UIMainStoryboardFile is not present (or blank)." but there is no info.plist because it is no longer required. Downloaded sample code runs and connects to peripherals, so Bluetooth is working on my iPhone and the Bluetooth device is accessible. My older attempts used to work, but now have the same problem. All attempts have "Enable Bluetooth to connect to Device" in the Privacy - Bluetooth Info.plist setting. Something is fundamentally wrong with many different code attempts. I have searched all the various settings for mention of SwiftUI or Storyboard, but not found them in working or failing projects. The downloaded code which works has minimum deployment iOS 14.0 and Swift Compiler Language Version Swift 5. My latest code attempt has minimum deployment iOS 16 and Swift 5. All code is target device iPhone (I am testing on iPhone 16e running iOS 26.2.1) and developing with Xcode 26.2 on MacBook Air M1 running the latest Tahoe. I do a Clean Build Folder before every test, and have tried re-starting both Mac and iPhone. How can my coding fail so spectacularly?

Hello, After upgrading to macOS 26.2, I’ve noticed a significant performance regression when calling evaluateJavaScript in an iOS App running on Mac (WKWebView, Swift project). Observed behavior On macOS 26.2, the callback of evaluateJavaScript takes around 3 seconds to return. This happens not only for: evaluateJavaScript("navigator.userAgent") but also for simple or even empty scripts, for example: evaluateJavaScript("") On previous macOS versions, the same calls typically returned in ~200 ms. Additional testing I created a new, empty Objective-C project with a WKWebView and tested the same evaluateJavaScript calls. In the Objective-C project, the callback still returns in ~200 ms, even on macOS 26.2. Question Is this a known issue or regression related to: iOS Apps on Mac, Swift + WKWebView, or behavioral changes in evaluateJavaScript on macOS 26.2? Any information about known issues, internal changes, or recommended workarounds would be greatly appreciated. Thank you. Test Code Swift class ViewController: UIViewController { private var tmpWebView: WKWebView? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. setupUserAgent() } func setupUserAgent() { let t1 = CACurrentMediaTime() tmpWebView = WKWebView(frame: .zero) tmpWebView?.isInspectable = true tmpWebView?.evaluateJavaScript("navigator.userAgent") { [weak self] result, error in let t2 = CACurrentMediaTime() print("[getUserAgent] \(t2 - t1)s") self?.tmpWebView = nil } } } Test Code Objective-C - (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions { NSTimeInterval startTime = [[NSDate date] timeIntervalSince1970]; WKWebView *webView = [[WKWebView alloc] init]; dispatch_async(dispatch_get_main_queue(), ^{ [webView evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id result, NSError *error) { NSTimeInterval endTime = [[NSDate date] timeIntervalSince1970]; NSLog(@"[getUserAgent]: %.2f s", (endTime - startTime)); }]; }); }

Hello. We are facing very silent and hardly replicable issue. All UserDefaults.standard data the application saved and was using to determine the state of app is lost and app behaves as if it was freshly installed. The issue always occurs only if we leave app on background for long time or if we manually swipe the app from the background apps. In case we swipe, this issue can occur in minutes, hours or up to 2 days by our latest testing. One important factor is that the app was developed using iOS18 in which issue never occured. Next it was being tested on iOS26 and it did everytime. Any currently available version of iOS26 reported this issue, all the way up to 26.2.1 (23C71). Our application is going through major upgrade of its whole lifecycle and services so it is possible this issue is caused by a bug in development as the production version does not report this issue neither on iOS26 of any version. The following list contains how we tried to fix this issue but none of which helped. App prewarming in the background (postpone all initialization including searching UserDefaults.standard for when isProtectedDataAvailable) Calling UserDefaults.standard.synchronize() everytime after saving data despite it is not recomended Built app using different SDK's (tested on iOS18 and iOS26 SDK) Distributed the app from local machine aswell as on TestFlight itself We searched through currently opened and closed issues for third-party libraries app uses regarding 'iOS26' and 'UserDefaults', especially those who were added recently with no success. The structure using which we save data into UserDefaults.standard did not change, we have only added few more settings to save through the lifecycle of the app after update. We estimate the overall increase is merely 30% more of what it used to be in previous version. Any ideas are much appreciated. We are considering to use different or fully custom ways to store app's settings.

In this app I use tooltips extensively. They work perfectly well, except in a popover where they may appear or not (just some flash and immediately disappear). In the popover there are 12 colour buttons, each with its own tracking area and 3 control buttons, with their tracking areas. Here when it works, hovering over "C" button or "Annuler" button: But then, when I move to another colour button, a few 2 or 3 may work, but most don't display their tooltip at all. I know that the tooltip is set because I replicate the message in a help line at the bottom of the screen and this line always update: Let messageForColor = "Choisir la couleur…" if button.isEnabled { // show tooltip button.toolTip = messageForColor } else { button.toolTip = nil } if button.isEnabled { // Shows helpline at the bottom of screen button.helpMessage = messageForColor } Maybe it comes from some useDefault (I modified NSInitialTool TipDelay and I'm not sure I have reset to the default value) I noted that if I wait for 10 seconds or so (keeping the popover opened), everything seems to work properly again. Just as if there was some lengthy initialisation going on. So questions: Is there a known issue of Tooltips in a popover ? Are there other parameters to set in userDefaults to avoid immediate disparition of the tooltip in popover ? How to reset the factory setting for the UserDefaults in the app ?

Hi, I recently built an app and I’m planning to publish it on the App Store. Since the Swift Student Challenge (SSC) is coming up, I’m also considering submitting the same project by converting it into a Swift Playground (with some content trimmed to meet the rules). I believe both I and the project are eligible. My question: if I publish the app on the App Store first and then submit it to SSC, could that violate the rules or lead to rejection? I also have a concern: because I’m a minor, Apple requires the App Store developer name to be my mother’s. However, the app was entirely developed by me. my mother and anyone else did not participate(My mother can't even use a computer.). I’m worried this might create confusion and make judges think I copied someone else’s work, which I did not. Would you recommend publishing on the App Store now, waiting until after SSC, or taking a different approach? Thank you.

Lately I am getting this error. GenerativeModelsAvailability.Parameters: Initialized with invalid language code: en-GB. Expected to receive two-letter ISO 639 code. e.g. 'zh' or 'en'. Falling back to: en Does anyone know what this is and how it can be resolved. The error does not crash the app

Hi everyone. Can you help me with my settings icon design. I`m trying to create circular setting button using Menu. My code here: struct MenuView: View { var body: some View { Menu { Text("Hello") Text("How are you") } label: { Image(systemName: "gearshape.fill") .clipShape(Circle()) } .clipShape(Circle()) .padding(.top, 10) .padding(.leading, 20) } } You can see my try, this one looks wrong. It should be like this: Just Circle with setting image inside. Thank you an advance 😭🙏🛐

I am using the native SwiftUI WebView and WebPage APIs (iOS 26+) and would like to implement file download functionality using the native SwiftUI WebView. However, I have not been able to find any APIs equivalent to WKDownload. In WKWebView, the WKDownload API can be used to handle downloads. I am looking for a similar API or recommended approach in the native SwiftUI WebView that would allow downloading files. If anyone has guidance or suggestions on how to implement this, I would appreciate your help.

I'm currently using Swift to write an independent Apple Watch app for watchOS 7+. My app uses Location Services, and in case the user doesn't allow that at first, I'd like to have a button inside my watchOS app to send my user to the part of the Settings app (inside watchOS) where he can give the appropriate permissions for the app. I know that in iOS/macOS you can use the openSettingsURLString string from UIApplication to do what I want, but it's not available in watchOS and I haven't found any equivalent resource inside the WKExtension class (normally the equivalent for UIApplication in the watchOS environment). Does anyone know if there's any way to programatically open the Apple Watch Settings app from my watchOS app? I'm asking since as far as I understand asking for Location permissions again would not work since the user has already refused to allow the permissions before, making the authorization status "denied". I understand as well that there's the possibility of showing a modal and directing the user to go to Settings and allow the use of location services (as in "Please go to Settings > Privacy > Location Services > [AppName] to allow the use of location services") but I'd like if I could direct the user there instead as one might do in iOS. The code below is what I'm trying to do - but (of course) it crashes since I'm not actually passing any system URL. .alert(isPresented: $alertVisible) { Alert (title: Text("Please allow our app to use location services in order to get Weather Data"), message: Text("Go to Settings?"), primaryButton: .default(Text("Settings"), action: { WKExtension.shared().openSystemURL(URL(string: "")!) //UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!) }),

I’ve notice that in Maps, some pins contain images and do not have the little triangle at the bottom of it, yet they still animate the same when clicked. How could this be achieved? I believe the name of this annotation is MKMapFeatureAnnotation. I've tried this and it did not give the same result. I'm able to create a custom MKMarkerAnnotationView but it does not animate the same (balloon animation like the MKMapFeatureAnnotation). I was looking forward to create a custom MKMapFeatureAnnotation similar in design which would animate the same. Unfortunately, I cannot create a custom MKMapFeatureAnnotation because everything is privated

I tried making a concurrency-safe data queue. It was going well, until memory check tests crashed. It's part of an unadvertised git project. Its location is: https://github.com/CTMacUser/SynchronizedQueue/commit/84a476e8f719506cbd4cc6ef513313e4e489cae3 It's the blocked-off method "`memorySafetyReferenceTypes'" in "SynchronizedQueueTests.swift." Note that the file and its tests were originally AI slop.

In WKWebView, there is the WKUIDelegate method: func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {} This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view. However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests. As a workaround, I am using the following method: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {} In this method, when action.target == nil, I treat it as a new window request. My question: Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs? Code: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy { guard let webPage = webPage else { return .cancel } // Handle case where target frame is nil (e.g., target="_blank" or window.open) // This indicates a new window request if action.target == nil { print("Target frame is nil - new window requested") // WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here // Try to create a new WebPage through UI plugins if handleCreateWebPage(for: webPage, navigationAction: action) != nil { // Note: The new WebPage has been created and published to the view return .allow } } return .allow }

I have an NSWindowController with several IBOutlets created in storyboard. I want to add an NSView and fill it with some color. I need to place it at a specific position in views hierarchy. I have tried 2 ways, no one succeeds. First. include a custom view in storyboard connect to an IBOutlet in an init of controller, set the layer for the view Result: crash Second build programmatically Result: I do not find where to put this code in the controller code That's basic Cocoa, but way more painful than iOS.

Overview In iOS 26, a List embedded in a NavigationStack inside a TabView exhibits a visual glitch when switching tabs. When the list is scrolled such that some rows are partially obscured by the navigation bar, the system correctly applies a fade/opacity effect to those rows. However, if the user switches to another tab while rows are in this partially obscured (faded) state, those rows briefly flash at full opacity during the tab transition before disappearing. This flash is visually distracting and appears to be inconsistent with the intended scroll-edge opacity behavior. The issue occurs only for rows partially obscured by the navigation bar. Rows partially obscured by the tab bar do not exhibit this flashing behavior. Steps to Reproduce: Run the attached minimal reproduction on iOS 26. Open the first tab. Scroll the list so that some rows are partially hidden behind the navigation bar (showing the native faded appearance). While rows are in this partially faded state, switch to the second tab. Observe that the faded rows briefly render fully opaque during the tab switch. Expected Behavior: Rows that are partially obscured by the navigation bar should maintain consistent opacity behavior during tab transitions, without flashing to full opacity. import SwiftUI @main struct NavBarReproApp: App { /// Minimal repro for iOS 26: /// - TabView with two tabs /// - First tab: NavigationStack + List /// - Scroll so some rows are partially behind the nav bar (faded) /// - Switch tabs: those partially-faded rows briefly flash fully opaque. Partially faded rows under the tab bar do not flash private let items = Array(0..<200).map { "Row \($0)" } var body: some Scene { WindowGroup { TabView { NavigationStack { List { ForEach(items, id: \.self) { item in Text(item) } } .navigationTitle("One") .navigationBarTitleDisplayMode(.inline) } .tabItem { Label("One", systemImage: "1.circle") } NavigationStack { Text("Second tab") .navigationTitle("Two") .navigationBarTitleDisplayMode(.inline) } .tabItem { Label("Two", systemImage: "2.circle") } } } } }
