Dear DTS Engineer, I hope this message finds you well. I am currently developing a Mac desktop application using the GTKMM framework, and I have some questions regarding the distribution of such an application through the Mac App Store. Project Context: I am building a native Mac desktop application using GTKMM as the UI framework. As GTKMM does not rely on macOS's AppKit or UIKit, my application does not use these Apple-specific frameworks for the UI. Instead, GTKMM provides its own cross-platform UI components. While this approach allows me to target macOS alongside Linux and Windows, I am uncertain whether this setup will be compatible with the Mac App Store's submission guidelines. My Questions: App Store Compatibility: Is it possible to distribute a macOS desktop application built with GTKMM (without using AppKit or UIKit) on the Mac App Store? App Store Guidelines: Are there specific App Store guidelines I should be aware of when submitting a non-native, non-AppKit UI-based app, such as one using GTKMM for macOS? Notarization & Code Signing: Does my app need to use AppKit/UIKit to meet the code signing and notarization requirements, or can I proceed with signing and notarizing a GTKMM-based app? App Store Review Process: Will the absence of AppKit/UIKit affect the review process or the acceptance of the app into the Mac App Store? I would greatly appreciate any guidance or clarification on these points. If you need additional details about my development environment or the specific technologies I'm using, please let me know. Thank you for your time and assistance.

Hi. If the app is in landscape only and when the SKStoreProductViewController is presented, the safeArea changes to what looks like a portrait mode safe area. When the SKStoreProductViewController is dismissed, the safeArea does NOT revert back to the original values. Is there a way to force the safeArea to "reset"? I've submitted some bug tickets through Apple Feedback but I haven't received any response about it. The below code will pop up the SKStoreProductViewController and if you have a UIView that is constrained to the safe area, then you can visibly notice that the safe area is changed and doesn't go back. I have tested this on iPhone 14 Pro, iPhone 15, and iPhone 16 Pro and in the Simulators. The incorrect behavior happens on those and probably more. Thanks. #import "ViewController.h" #import <StoreKit/StoreKit.h> @interface ViewController () @property (nonatomic, strong) SKStoreProductViewController *productViewController; @end @implementation ViewController - (IBAction)buttonTapped:(id)sender { self.productViewController = [[SKStoreProductViewController alloc] init]; NSDictionary *parameters = @{ @"id" : @"6443575749" }; [self.productViewController loadProductWithParameters:parameters completionBlock:^(BOOL result, NSError * _Nullable error) { [self presentViewController:self.productViewController animated:YES completion:^{ // presented // The panel that is constraint to the safe area visibly shows that the safe area is no longer correct. }]; }]; } @end

Hello everyone, I’m experiencing an issue with the Android Emulator in Android Studio (version Ladybug) on my Mac running macOS Monterey (12.7). The emulator frequently displays the message “System UI isn’t responding” and then crashes. I've tried a few troubleshooting steps, including: Restarting Android Studio and the emulator. wipe data on AVD. tried to change the emulator performance from automatic to hardware but this option isn't available to me. Despite these efforts, the problem persists. Has anyone else encountered this issue? Any suggestions or solutions would be greatly appreciated!

Hey, I have an app that user selects wallpaper for iPhone. I want a feature that user can set wallpaper direct from app itself for lock screen and home screen not download the image and manually set the wallpaper. As my research there was a PhotoLibrary api that contains PLWallpaperImageViewController.h which allows you to set wallpaper directly. Thank You!

If I put the phone flat on a table, the left and right swipe gestures is not working but up and down gestures works. Only when I put the iPhone to some vertical degree, the left and right swipe works. Tested on 2 iPhone 7 Plus and 2 iPhone 13. Anyone has similar experience? If yes, why?

I am trying to change UITabBar background color runtime as theme changed. It is already working in iOS 17 as I am updating UITabBar.appearance().barTintColor and tintColor But for iOS first i need to change because I don't want that new elevated tabbar so I create custom tabbar controller as described in https://stackoverflow.com/questions/78631030/how-to-disable-the-new-uitabbarcontroller-view-style-in-ipados-18 Accepted Answer by awulf. And by doing this, My tabbar looks same like Old and it is working in iPhone and ipad for iOS 16, iOS 17 and iOS 18 too. But the issue is that I am unable to change my tabbar background color. I have also checked this forum: https://forums.developer.apple.com/forums/thread/761056 But not able to change I have set below 3 properties but no effect let appearance = UITabBar.appearance() appearance.backgroundColor = appearance.barTintColor = appearance.tintColor = I have created CustomTabBarController in storyboard and all working fine Also the appearance changed only once per application lifecycle. It will change color by restarting the app then it will pick last selected theme and the colors are changed. but not able to change colors runtime I have also did below code for reloading purpose tabBar.setNeedsLayout() tabBar.setNeedsDisplay() But nothing work

We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered odd behavior of [UIDocumentPickerViewController initForOpeningContentTypes: asCopy:YES] when reading large archive files from a USB drive. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with bleeding edge iPadOS 18. Here's our Objective-C code which presents the picker: NSArray* contentTypeArray = @[UTTypeAppleArchive]; UIDocumentPickerViewController* docPickerVC = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:contentTypeArray asCopy:YES]; docPickerVC.delegate = self; docPickerVC.allowsMultipleSelection = NO; docPickerVC.shouldShowFileExtensions = YES; docPickerVC.modalPresentationStyle = UIModalPresentationPopover; docPickerVC.popoverPresentationController.sourceView = self.view; [self presentViewController:docPickerVC animated:YES completion:nil]; The UIDocumentPickerViewController remains visible until the selected external archive file has been copied from the USB drive to the app's local tmp sandbox. This may take several seconds due to the slow access speed of the USB drive. During this time the UIDocumentPickerViewController does NOT disable its tableview rows displaying files found on the USB drive. Even the most patient user will tap the desired filename a second (or third or fourth) time since the user's initial tap appears to have been ignored by UIDocumentPickerViewController, which lacks sufficient UI feedback showing it's busy copying the selected file. When the user taps the file a second time, UIDocumentPickerViewController apparently begins to copy the archive file once again. The end result is a truncated copy of the selected file based on the time between taps. For instance, a 788 MB source archive may be copied as a 56 MB file. Here, the UIDocumentPickerDelegate receives a 56 MB file instead of the original 788 MB of data. Not surprisingly, AppleArchive fails to decrypt the local copy of the archive because it's missing data. Instead of failing gracefully, AppleArchive crashes in AAArchiveStreamClose() (see forums post 765102 for details). Does anyone know if there's a workaround for this strange behavior of UIDocumentPickerViewController?

Hi everyone, I’m wondering about Core Data. When creating a private context using newBackgroundContext(), does it automatically set the parent to the view context, or is it independent? Additionally, if I update objects in the context created by newBackgroundContext(), will the view context automatically notice the changes, and vice versa? Lastly, are there other ways to set parent-child context relationships between contexts? I'd appreciate it if anyone could clarify this for me. Thanks in advance! 😊

Hello! After upgrading to Xcode 16 & Swift 6 & iOS 18 I starting receiveing strange crashes. Happens randomly in different view and pointing to onGeometryChange action block. I added DispatchQueue.main.async { in hopes it will help but it didn't. HStack { ... } .onGeometryChange(for: CGSize.self, of: \.size) { value in DispatchQueue.main.async { self.width = value.width self.height = value.height } } As far as I understand, onGeometryChange is defined as nonisolated and Swift 6 enforce thread checking for the closures, SwiftUI views are always run on the main thread. Does it mean we can not use onGeometryChange safely in swiftui?

I have a CarPlay navigation app and I would like to allow the user to speak an address and have our app search at that location. In the Waze app, it provides a button to tap, then it brings up a CPVoiceControlTemplate and you can give it directions or a location and it will then show you search results including the text you spoke as the title. I assume that app would have the same limitations as I do, so I am wondering how another app might do this? It was suggested that I use an App Intent with suggested phrases and then a Shortcut could perform the action. Is there documentation on this somewhere or am I going in the wrong direction here? Obviously Waze is doing what I am wanting so there must be a way. Can anyone point me in the right direction?

So basically, if I put a .navigationModifier inside of a NavigationStack that's inside of a TabView, AND I supply a path argument to NavigationStack. I get this error: Do not put a navigation destination modifier inside a "lazy” container, like `List` or `LazyVStack`. These containers create child views only when needed to render on screen. Add the navigation destination modifier outside these containers so that the navigation stack can always see the destination. There's a misplaced `navigationDestination(for:destination:)` modifier for type `NavPath`. It will be ignored in a future release. Does TabView or NavigationStack suddenly become lazy when I put the path parameter in? It also causes weird unexplained behavior if I start removing tabs using state, but I do think I'm not supposed to do that. Code for reference: var body: some View { @Bindable var nm = navManager TabView{ NavigationStack(path: $nm.pathStack){ HomeView() // A custom view .navigationDestination(for: NavPath.self) { np in // NavPath is a custom struct that's hashable switch np.pathId { case "home": NavigationLazyView(HomeView()) // Ignore the NavigationLazyView, does not affect ...

I have a UIViewController that presents a UIPrintInteractionController when a user selects the print button on the UI. The problem is starting in iOS 18 (currently using beta 7) when the print controller is presented the UIViewController's viewWillAppear() is being called. This did not happen in earlier iOS releases and is causing unwanted behavior in the app. Is this a bug or will this be the behavior going forward?

Hi All! I've encountered a SwiftUI NavigationSplitView bug in my app that I'd appreciate help with, I've spent quite some time trying to work out a solution to this problem. I have a main list, which has either a Location or LocationGroup. When selecting a Location, the detail view is presented. When selecting a LocationGroup, a subsequent list of Locations are presented (from the group). When tapping on any of these Locations, the NavigationStack does not animate (push the view), and when tapping back from it, it jumps to the main selection. The overall goal is to be able to present within the detail: of a NavigationSplitView a NavigationStack, and to be able to push onto that stack from both the main NavigationSplitView's list, and from the detail. I created the following sample code that reproduces the issue: ContentView.swift public enum LocationSplitViewNavigationItem: Identifiable, Hashable { case location(Location) case locationGroup(LocationGroup) public var id: UUID? { switch self { case .location(let location): return location.id case .locationGroup(let locationGroup): return locationGroup.id } } } struct ContentView: View { @State private var columnVisibility = NavigationSplitViewVisibility.doubleColumn @State private var selectedNavigationItem: LocationSplitViewNavigationItem? var body: some View { NavigationSplitView(columnVisibility: $columnVisibility) { LocationListView(selectedItem: $selectedNavigationItem, locationData: LocationSampleData(locations: LocationSampleData.sampleLocations, locationGroups: LocationSampleData.sampleLocationGroups)) } detail: { if let selectedLocation = selectedNavigationItem { switch selectedLocation { case .location(let location): LocationDetailView(selectedLocation: location) case .locationGroup(let locationGroup): LocationListView(selectedItem: $selectedNavigationItem, locationData: LocationSampleData(locations: locationGroup.locations)) } } } .navigationSplitViewStyle(.balanced) } } LocationListView.swift struct LocationListView: View { @Binding public var selectedItem: LocationSplitViewNavigationItem? var locationData: LocationSampleData var body: some View { List(selection: $selectedItem) { if let locations = locationData.locations { ForEach(locations) { location in NavigationLink(value: LocationSplitViewNavigationItem.location(location)) { Text(location.name) .bold() } } } if let locationGroups = locationData.locationGroups { ForEach(locationGroups) { locationGroup in NavigationLink(value: LocationSplitViewNavigationItem.locationGroup(locationGroup)) { Text(locationGroup.name) .bold() .foregroundStyle(.red) } } } } .navigationTitle("Saturday Spots") .navigationBarTitleDisplayMode(.large) } } LocationDetailView.swift struct LocationDetailView: View { var selectedLocation: Location var body: some View { Text(selectedLocation.name) .font(.largeTitle) .bold() .foregroundStyle(LinearGradient( colors: [.teal, .indigo], startPoint: .top, endPoint: .bottom )) .toolbarBackground( Color.orange, for: .navigationBar ) .toolbarBackground(.visible, for: .navigationBar) } } Location.swift import CoreLocation struct LocationSampleData { var locations: [Location]? var locationGroups: [LocationGroup]? static let sampleLocations: [Location]? = Location.sample static let sampleLocationGroups: [LocationGroup]? = [LocationGroup.sample] } public struct Location: Hashable, Identifiable { var name: String var coordinates: CLLocationCoordinate2D var photo: String public var id = UUID() static public let sample: [Location] = [ Location(name: "Best Bagel & Coffee", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"), Location(name: "Absolute Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"), Location(name: "Tompkins Square Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"), Location(name: "Zabar's", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"), ] static public let oneSample = Location(name: "Absolute Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf") } public struct LocationGroup: Identifiable, Hashable { var name: String var locations: [Location] public var id = UUID() static public let sample: LocationGroup = LocationGroup(name: "Bowling", locations: [ Location(name: "Frames Bowling Lounge", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"), Location(name: "Bowlero Chelsea Piers", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf") ]) } extension CLLocationCoordinate2D: Hashable { public static func == (lhs: Self, rhs: Self) -> Bool { return lhs.latitude == rhs.latitude && lhs.longitude == rhs.longitude } public func hash(into hasher: inout Hasher) { hasher.combine(latitude) hasher.combine(longitude) } }

How to capture program crash exceptions with swift UI

UITextView erroneously overrides string attributes when applying spellchecker annotation attributes. It doesn't need any particular setting. Default UITextView instance with attributed text let textView = UITextView(usingTextLayoutManager: true) textView.spellCheckingType = .yes Once spellcheck attributes get applied, other attributes like foreground color get applied to the misspelled words. This behavior happens only on Mac Catalyst, and started to appear on macOS 14 or newer. Please check the Xcode project that demonstrates the issue https://github.com/user-attachments/files/16689336/TextEditor-FB14165227.zip Open TextEditor project Select "My Mac (Mac Catalyst)" build destination Run the project. A window with a text area should appear Select the whole text (either using mouse or keyboard command+a) Observe how foregroundColor changes to text (this is the issue) That eventually led to crash 💥 This bug is reported to Apple FB14165227

Hi there! My app supports one language by default Ukrainian (uk) and does not support multiple languages. In Xcode settings "Development Language" is set to Ukrainian by default also. I have a PKAddPassButton on a ViewController and "Add to Apple Wallet" always appears in Ukrainian (Tested on real device iOS 15/16/17). Apple's "Getting Started with Apple Pay: In-App Provisioning, Verification, Security, and Wallet Extensions” document states that "The Add to Apple Wallet button adapts to the device language and the light and dark appearances, but the issuer app needs to adapt the language of the row selector text." When I change device language to French the “Add to Apple Wallet” button does not change to French. I created a fresh swift app, added PKAddPassButton the "Add to Apple Wallet" button, General -> Language & Region changed the device language to French, etc, but the "Add to Apple Wallet" button is always in English. Has anyone run into the same issue? How to adapt the "Add to Apple Wallet" button to the device system language?

I made a custom slider by subclassing UISlider, and I'm trying to add scrubbing functionality to it, but for some reason the scrubbing is barely even noticeable at 0.1? In my code, I tried multiplying change in x distance by the scrubbing value, but it doesn't seem to work.

I'm working on a SwiftUI application that uses programmatic navigation with enums in a NavigationStack. My app is structured around a TabView with different tabs, each having its own navigation stack. I need to navigate to the same view from different tabs, but each tab has a separate navigation stack with custom paths. Here's a simplified version of my setup: class AppState: ObservableObject { @Published var selectedTab: Tab = .feeds @Published var tabANavigation: [TabANavDestination] = [] @Published var tabBNavigation: [TabBNavDestination] = [] } enum TabANavDestination: Hashable { case itemList() case itemDetails(String) } enum TabBNavDestination: Hashable { case storeList() case itemList() case itemDetails(String) } For example: TabA: ItemsListScreen -> DetailsScreen. TabB: StoreList -> ItemsListScreen -> DetailsScreen I want to navigate from ItemsListScreen to DetailsScreen, but I can't use the same method to append the navigation state in both tabs: appState.tabANavigation.append(.itemDetails(id)) How can I manage navigation across these different tabs, ensuring that the same screen (e.g., DetailsScreen) is accessible from different paths and tabs with their own navigation stacks? What’s the best approach to handle this scenario in a complex navigation setup?

In iOS18, Not able to use the UITabBarControllerDelegate.tabBarController(:didSelectTab:previousTab:) function. Since it have duplicate parameter name for didselectTab and previousTab , we're getting Invalid redeclaration of 'tab' error.
