Scrolling and zooming I have two apps that utilize the Apple Maps and since I updated my xcode to use IOS18, some of the functionalities have either been missing or glitching, and when I roll back to IOS17.5, everything seems to work fine. When I use MKMapView and use mapView.isZoomEnabled = true mapView.isScrollEnabled = true Scrolling and zooming is still not working on IOS18 but IOS17.5 works fine. Clicking on custom annotations When I press on a custom annotation I add to the MapView, the gesture is sometimes recognized and most of the times not recognized. If I have 20 annotations, there is a possibility only 2 of them respond to tap gestures. Below is how I define the annotation. Annotation("Pin", coordinate: CLLocationCoordinate2D(latitude: latitude, longitude: longitude), anchor: .bottom) { Button(action: {print ("Pressed annotation"){ CustomPin() } }

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

To set up iOS 18 widget tint mode without any modifications, follow the steps below. I hope this helps many people. You just need to add one line. .containerBackgroundRemovable(false) ex) struct create_view: Widget { let kind: String = "CalendarWidget" var body: some WidgetConfiguration { StaticConfiguration(kind: kind, provider: Provider()) { entry in calendar_widgetEntryView(entry: entry) } .supportedFamilies([.systemLarge]) .containerBackgroundRemovable(false) .contentMarginsDisabledIfAvailable() } } Before: After :

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?

I am using SwiftUI NavigationView to navigate. I cant find how can i disable swipe from the leftmost part of the screen for navigation bar. In tried this way , but it doesn't work for me: struct DisableSwipeBackGesture: ViewModifier { func body(content: Content) -> some View { content .background(DisableBackSwipeGestureView()) } } struct DisableBackSwipeGestureView: UIViewControllerRepresentable { typealias UIViewControllerType = DisableSwipeBackViewController func makeUIViewController(context: Context) -> DisableSwipeBackViewController { DisableSwipeBackViewController() } func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {} func makeCoordinator() -> Coordinator { return Coordinator() } class Coordinator: NSObject, UIGestureRecognizerDelegate { func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { return false } } } final class DisableSwipeBackViewController: UIViewController { override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) if let navigationController = self.navigationController { if let interactivePopGestureRecognizer = navigationController.interactivePopGestureRecognizer { interactivePopGestureRecognizer.delegate = self interactivePopGestureRecognizer.isEnabled = false } } } } extension DisableSwipeBackViewController: UIGestureRecognizerDelegate { func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { return false } } extension View { func disableSwipeBackGesture() -> some View { self.modifier(DisableSwipeBackGesture()) } } Is there a way to disable this feature?

I used standard font styles in an iOS app. For example .font(.headline). I hoped that developing this way would allow the adoption of the app to other platforms, relatively easy. However, when trying to run for iPadOS, the text did not increase in size to occupy the more abundant space offered by larger screen, but it actually shrank. Overall, the app does not look great "automatically". Why does it happen? What is the best practice for cross platform development with SwiftUI (with regards to font sizes). I want to make as little as possible human interface design decisions on my own and just let SwiftUI take care of everything. (But I also want the results to look as Apple would consider great looking)

With macOS 15, I'm noticing a new behavior when initializing a NavigationSplitView with columnVisibility. For example: @State var sidebar = NavigationSplitViewVisibility.all var body: some View { ZStack { NavigationSplitView(columnVisibility: $sidebar) { This code previous to macOS 15 would behave as expected: the sidebar could be toggled and the views would stay intact. However, when you update sidebar after updating to macOS 15, the entire view is reinitialized, meaning that every single child view that depends on this parent view is also reinitialized. Is this expected behavior? Simply clicking the toggle sidebar UI button does not reinitialize views, but when you initialize a NavigationSplitView with the column visibility, changes to the sidebar will completely reload the UI. Has anyone else experienced this?

Hi, I'm experiencing a layout issue in SwiftUI when using TabView, NavigationStack, and a List in a specific navigation flow. Here's how to reproduce it: Tap on Tab 3. Tap "Tap Me to go to the subview" to navigate to the detail view. In the detail view, tap Back to return to Tab 3. Tap "Tap Me to go to the subview" again. Problem: When returning to the detail view, the content (especially the List) appears incorrectly positioned within the safe area, as if it's overlapping or misaligned with the navigation bar. This happens only when navigating back and forth after dismissing a sheet presented from a different tab. This animated gif shows the workflow to visualize the problem: Expected Behavior: The content should consistently respect the safe area and be positioned correctly under the navigation bar. Thanks in advance for your help! Here is the complete code to reproduce the issue: import SwiftUI @Observable class MenuSelector { var initialIndex: Int var customTabIndex: Int var isCustomTabSelected: Bool = false private var previousIndex: Int init(customTabIndex: Int, initialIndex: Int = 0) { self.initialIndex = initialIndex self.customTabIndex = customTabIndex self.itemSelected = initialIndex self.previousIndex = initialIndex } var itemSelected: Int { didSet { if itemSelected == customTabIndex { previousIndex = oldValue itemSelected = oldValue isCustomTabSelected = true } } } } struct NavigationStackSpikeView: View { @State private var tabSelector = MenuSelector(customTabIndex: 1) var body: some View { TabView(selection: $tabSelector.itemSelected) { Text("Tab 1") .tabItem { Text("Tab 1") } .tag(0) Text("I want to present a sheet for this tab") .tabItem { Text("Action") } .tag(1) Tab3View() .tabItem { Text("Tab 3") } .tag(2) } .sheet(isPresented: $tabSelector.isCustomTabSelected) { SheetView() } } } struct Tab3View: View { @State private var navigationPath = NavigationPath() var body: some View { NavigationStack(path: $navigationPath) { VStack { NavigationLink(value: Destination.subview) { Text("Tap Me to go to the subview") } } .navigationDestination(for: Destination.self) { destination in switch destination { case .subview: DetailView() } } } } enum Destination: Hashable { case subview } } struct DetailView: View { var body: some View { VStack { List { Text("A detail") } .listStyle(.plain) } .navigationTitle("Details") .navigationBarTitleDisplayMode(.inline) } } struct SheetView: View { @Environment(\.dismiss) var dismiss var body: some View { VStack { Text("I'm a sheet") Button("Dismiss") { dismiss() } } } } #Preview { NavigationStackSpikeView() }

I have a (pretty basic) app I have developed which essentially just opens a pre-defined website (via URL) in WebView. It operates nicely in iOS and almost exactly as expected when run on my M1 in macOS with the exception that in macOS it keeps popping up a grey bar which ... after some investigating ... I have determined appears to be the virtual keyboard. Pressing escape clears it however I am trying to find some way of preventing it from coming up in the first place when the app is run in macOS. Is there a (hopefully simple) solution either through code or some app setting for this?

Hello Apple Developer Community, I am encountering an issue with app icon rendering after updating an app on devices running iOS 18 or newer. Below are the details: Issue Summary: When updating an app from a previous version (with separate light and dark mode icons) to the latest version (where both modes use the same icon), the icon changes are not reflected consistently across all system menus. Steps to Reproduce: Set the device mode to Dark Mode. Install the previous app version (with different icons for light and dark modes). Update the app to the latest version (where both modes use the same icon). Change the device mode to Light Mode. Switch back to Dark Mode. Expected Behavior: The app icon should remain consistent across all system menus (Home Screen, Spotlight search, etc.) when switching between Light and Dark Modes. Observed Behavior: The app icon displays correctly on the Home Screen but inconsistencies appear in other menus, such as Spotlight search or when toggling between modes. For instance, in Dark Mode, the icon may revert to the previous black-colored logo or display incorrectly compared to the updated design. Additional Notes: The asset catalog is configured correctly, with identical icons set for both light and dark modes in the latest app version. Incrementing the build number was implemented during the update. A manual device restart resolves the issue on some devices, but not consistently. Questions for the Community: Has anyone else experienced similar app icon caching or rendering issues in iOS 18 or later? Are there known workarounds or specific configurations to ensure consistent icon rendering across all system menus? Could this be related to iOS 18's icon caching or appearance handling mechanisms? Your insights and suggestions would be greatly appreciated. Thank you for your time!

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

Developing on Monterey 12.7.5 I'm having trouble with updating subitems on NSToolbarItemGroup when selecting the item directly from the NSToolbar items array. I select the group item off the items array on the toolbar, and then call setSubitems: on the item, with a new array of NSToolbarItems. The group item disappears from the toolbar. It seems to leave a blank invisible item in the toolbar taking up space. I can't manually reinsert the item into the toolbar until I drag out the blank item, then drag back in the real item. Once dragged back in from the palette it displays correctly. The workaround I've come up with is to remove the item with NSToolbar removeItemAtIndex: and reinsert it with NSToollbar insertItemWithItemIdentifier:atIndex:. This works to update the subitems. Every other toolbar item property that I've tried has been able to update the item directly in the toolbar. It's only the group item's subitems that don't want to update correctly. Is there a correct way to do this that I'm missing? Calling [toolbar validateVisibleItems] didn't seem to help.

I want to support Genmoji input in my SwiftUI TextField or TextEditor, but looking around, it seems there's no SwiftUI only way to do it? If none, it's kind of disappointing that they're saying SwiftUI is the path forward, but not updating it with support for new technologies. Going back, does this mean we can only support Genmoji through UITextField and UIViewRepresentable? or there more direct options? Btw, I'm also using SwiftData for storage.

ScrollView scrolling works on Mac Catalyst apps with a Trackpad just fine but the same cannot be said for mouses with scroll wheels. Is there any way to achieve scrolling with scroll wheels?

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() } }

Hi, after updating Xcode to Version 16.1, I started a new multiplatform project targeting macOS and iOS. Everything worked fine until I added Firebase SDK 11.4 (using Swift Package Manager). Now, I'm facing an issue where the preview is not possible with "My Mac" after adding Firebase SDK, even with a very simple view like: struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() } } #Preview { ContentView() } However, previewing with iPhone or iPad works fine. This is really frustrating. When I run the app on a simulator (Mac, iPhone, or iPad), everything works perfectly. The error shown is Cannot preview in this file: Failed to launch [AppName] with the following path: /Users/[myname]/Library/Developer/Xcode/DerivedData/[AppName-gemeoxpjlzrshfifmgmqrkcxdeiz/Build/Products/Debug/FirebaseFirestoreInternal.framework/FirebaseFirestoreInternal Run Destination: macOS 15.1. What I have tried so far: Cleaned the build folder Re-installed Firebase SDK Any insights would be greatly appreciated! Thank you!

I’m experiencing an issue with the search bar on my iPhone 16 Pro. When I start typing in the search bar (as shown in the screenshot), the keyboard overlaps with the search suggestions, making it hard to see the contacts and apps that are displayed. The interface seems cluttered, and it becomes difficult to accurately tap on the desired suggestion or contact. Steps to Reproduce: 1. Swipe down to access the search bar on the iPhone 16 Pro. 2. Type a few letters to bring up suggestions for apps, contacts, and messages. Expected Result: The search results should display clearly above the keyboard without overlapping or cluttered suggestions. Actual Result: The keyboard overlaps with the search results, making it difficult to view or select items accurately. Device and OS Details: • iPhone 16 Pro • iOS Version (please replace with your specific version) Has anyone else encountered this issue? Any insights on possible fixes or settings adjustments would be appreciated.
