I am in the process of evaluating Swift 6 and I noticed that when using the completion handler version of the requestAuthorization the application crashes with EXC_BAD_INSTRUCTION exception. Using this code: let center = UNUserNotificationCenter.current() center.requestAuthorization(options: [.alert, .sound, .badge]) { success, error in print(success) } Crashes when the project is build with Swift 6 and works normalising when build with Swift 5. The only solution that I have found so far is to switch to using the async version of that API: Task { let center = UNUserNotificationCenter.current() do { if try await center.requestAuthorization(options: [.alert, .sound, .badge]) == true { print("success") } else { print("fail") } } catch { print("Error") } } Is the a known issue? I have submitted feedback with ID "FB15294185".

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! 😊

The following code crashes on macOS 15 Sequoia: import Foundation let key = NSAttributedString.Key("org.example.key") let value = Value() let string = NSMutableAttributedString() string.append(NSAttributedString(string: "a", attributes: [:])) string.append(NSAttributedString(string: "b", attributes: [key: value])) string.append(NSAttributedString(string: "c", attributes: [:])) string.enumerateAttribute(key, in: NSRange(location: 0, length: string.length)) { value, range, stop in print(range) } class Value: Equatable, Hashable { static func == (lhs: Value, rhs: Value) -> Bool { return lhs === rhs } func hash(into hasher: inout Hasher) { hasher.combine(ObjectIdentifier(self)) } } The error is EXC_BAD_ACCESS (code=1, address=0x0) I wanted to run it on my external macOS 14 partition to confirm that it didn't crash before updating to macOS 15, but for some reason macOS will just restart and boot again into macOS 15. So I tried with macOS 13, which I was allowed to start for some reason, and I was able to confirm that the code doesn't crash. Is this a known issue, and is there a workaround? Removing the two lines that add the letters a and c, or just declaring class Value without conformance to Equatable, Hashable, interestingly, solves the issue.

Hello. I am having trouble trying to create a control in control center view that opens a specific view in my app using AppIntents (iOS18 )and WidgetKit, can someone help me please? I feel like the original videos and documentations are incomplete.

There is a significant rendering issue in PencilKit when using an iPad set to "More Space" display mode, combined with an Apple Pencil that supports hover functionality (e.g., Apple Pencil 2). This problem affects all applications that use PencilKit, including Apple's own Notes and Quick Note. The issue results in flickering black borders and subtle jittering while drawing, which is especially noticeable during tasks requiring precise handwriting, such as writing mathematical expressions. Due to the short strokes and frequent lifts and drops of the pencil, the jitter is much more pronounced, leading to visual discomfort and even dizziness after extended use. Steps to Reproduce: Open Settings on your iPad. Navigate to Display & Brightness > Display Zoom > More Space. Switch to the More Space display mode. Open the Notes app or trigger Quick Note from any application by swiping from the bottom-right corner. Start drawing or writing using the Apple Pencil (with hover functionality) in the writing area. Observe the display anomalies as you hover and write: Flickering black borders appear intermittently around the writing area. The strokes show subtle jittering whenever you lift and lower the pencil. This is particularly disruptive when writing short, precise strokes, such as those in mathematical expressions, where the frequent up-and-down motion makes the jitter more apparent. Expected Results: Smooth and stable drawing experience with no visual artifacts or jittering during interactions with the Apple Pencil, regardless of the display zoom settings. Actual Results: Flickering black borders intermittently appear during drawing. Jittering of strokes is noticeable, particularly when lifting and lowering the Apple Pencil for short strokes. This disrupts precise writing tasks, especially in cases like mathematical notation, where frequent pen lifts and short strokes make the jitter much more apparent. This can lead to discomfort (e.g., dizziness) after extended use. System-Wide Impact: This issue affects all apps that utilize PencilKit, including third-party apps such as Doodle Draw (link). Since PencilKit is a core framework, the rendering bug significantly degrades the user experience across multiple productivity and note-taking applications. Similar Reports: There are numerous discussions about this issue online, indicating that many users are experiencing the same problem. Reddit Discussion: https://www.reddit.com/r/ipad/comments/1f042ol/comment/ljvilv6/ Apple Support Thread Additionally, a feedback report (ID: FB15166022) related to this issue with Notes has been previously filed, but the bug remains unresolved. This bug severely impacts the usability of PencilKit-enabled apps, especially during tasks that involve frequent, precise pencil strokes, such as writing mathematical expressions. We kindly request the development team investigate this issue promptly to ensure a smooth, stable experience with the iPad's "More Space" display mode and Apple Pencil hover interaction.

Hi everyone, I'm working with the CarPlay TabBar template in my app. Is there a way to programmatically switch between tabs, or is this only possible through user interaction? Any guidance or clarification would be appreciated. Thanks!

Hi everyone, I'm working with the CarPlay TabBar template in my app. Is there a way to programmatically switch between tabs, or is this only possible through user interaction? Any guidance or clarification would be appreciated. Thanks!

Is it possible to disable user interaction for items in a CarPlay template? Based on my research, it seems that touch interaction is controlled by the system UI, and there isn't an API available to disable it.

Steps to reproduce: From my UINavigationController, call setViewControllers([vc1], animated: true) Then later call setViewControllers([vc2], animated: true) Results: In iOS 17, this behaves fine. In iOS 18, it crashes the UINavigationController. Both log: Attempt to present * on * which is already presenting * Workaround: use setViewControllers(...animated: false)

I’m trying to use the Link Presentation app in my SwiftUI app. When I try to fetch metadata, I get quite a few errors in the console. Here’s a stripped down version of the code that causes errors: public struct URLMetadataLoader { public static func metadata(for url: URL) async -> LPLinkMetadata? { let metadataProvider = LPMetadataProvider() do { let metadata = try await metadataProvider.startFetchingMetadata(for: url) return metadata } catch { print("Failed to get metadata for URL: \(error.localizedDescription)") return nil } } } The errors I get on every call to fetch metadata are below.

I have build a framework name is HansTranslation.framework for iOS 18 only, because it is include Translation. My app is okay when I call this framework on iOS 18 device, but it is crash on iOS 17.6. below is error info: Symbol not found: _$s7SwiftUI4ViewP013_Translation_aB0E15translationTask_6actionQr0D00D7SessionC13C onfigurationVSg_yAIYactF Referenced from: <4E09A66F-7D9E-3793-A2D6-1BE167EAD3F5> /private/var/containers/Bundle/Application/90A1EF03-09DA-43B5-8946-8186CF9CC804/B uild SRT.app/Frameworks/HansTranslation.framework/HansTranslation (built for ios 18.0 which is newer than running OS) <8F146BA4-EBE8-32C5-9CD8-E30077AD8088> /System/Library/Frameworks/_Translation_SwiftUI. framework/_Translation_SwiftUI I known that iOS 17.6 is NOT include "Translation_SwiftUI. framework", so there is crash.

Thanks.

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() } }

I don't know what triggered this in a previously-running application I'm developing: When I have the build target set to "My Mac (designed for iPad)," I now must delete all the app's build materials under DerivedData to get the app to build and run exactly once. Cleaning isn't enough; I have to delete everything. On second launch, it will crash without even getting to the instantiation of the application class. None of my code executes. Also: If I then set my iPhone as the build target, the app will build and run repeatedly. If I then return to "My Mac (designed for iPad)," the app will again launch once and then crash on every subsequent launch. The crash is the same every time: dyld[3875]: Symbol not found: _OBJC_CLASS_$_AVPlayerView Referenced from: <D566512D-CAB4-3EA6-9B87-DBD15C6E71B3> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Debugger/libViewDebuggerSupport.dylib Expected in: <4C34313C-03AD-32EB-8722-8A77C64AB959> /System/iOSSupport/System/Library/Frameworks/AVKit.framework/Versions/A/AVKit Interestingly, I haven't found any similar online reports that mention this symbol. Has anyone seen this behavior before, where the crash only happens after the first run... and gets reset when you toggle the target type?

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?

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!

I want to simulate the pressing of Fn (Globe) + Control + arrow keys combo, but I’m encountering an issue where the Fn modifier seems to be ignored, and the system behaves as if only Control + arrow keys are pressed. In macOS, the combination of Fn + Right Arrow (key code 124) is treated as End (key code 119), and even that didn’t have expected behavior. Instead of moving the window to the right edge of the screen on Sequoia, it switches to the next space, which is the default behavior for Control + Right Arrow. Demo: (I included Fn + Control + C to show that centering the window works for example.) import SwiftUI @main struct LittleKeypressDemo: App { var body: some Scene { Window("Keypress Demo", id: "keypress-demo") { ContentView() } .windowStyle(.hiddenTitleBar) .windowResizability(.contentSize) .windowBackgroundDragBehavior(.enabled) } } struct ContentView: View { var body: some View { VStack(spacing: 20) { KeyPressButton(icon: "arrowtriangle.right.fill", keyCode: 124) KeyPressButton(icon: "arrow.down.to.line", keyCode: 119) KeyPressButton(label: "C", keyCode: 8) } .padding() } } struct KeyPressButton: View { let icon: String? let label: String? let keyCode: CGKeyCode init(icon: String? = nil, label: String? = nil, keyCode: CGKeyCode) { self.icon = icon self.label = label self.keyCode = keyCode } var body: some View { Button(action: { simulateKeyPress(keyCode) }) { HStack { Image(systemName: "globe") Image(systemName: "control") if let icon = icon { Image(systemName: icon) } else if let label = label { Text(label) } } } .buttonStyle(.bordered) .controlSize(.large) } } func simulateKeyPress(_ keyCode: CGKeyCode) { let fnKey = VirtualKey(keyCode: 63, flags: .maskSecondaryFn) let controlKey = VirtualKey(keyCode: 59, flags: [.maskControl, .maskSecondaryFn]) let targetKey = VirtualKey(keyCode: keyCode, flags: [.maskControl, .maskSecondaryFn]) [fnKey, controlKey, targetKey].forEach { $0.pressAndRelease() } } struct VirtualKey { let keyCode: CGKeyCode let flags: CGEventFlags func pressAndRelease() { postKeyEvent(keyDown: true) postKeyEvent(keyDown: false) } private func postKeyEvent(keyDown: Bool) { guard let event = CGEvent(keyboardEventSource: nil, virtualKey: keyCode, keyDown: keyDown) else { return } event.flags = flags event.post(tap: .cghidEventTap) } } Expected behavior: Simulating the key combo Fn + Control + Right Arrow on macOS Sequoia should move the current window to the right half of the screen, instead of switching to the next desktop space. Questions: Is CGEventFlags.maskSecondaryFn enough to simulate the Fn key in combination with Control and the arrow keys? Are there alternative approaches or workarounds to correctly simulate this behavior? What’s the obvious thing I missing? (Btw., window management is completely irrelevant here. I’m specifically asking about simulating these key presses.) Any insights or suggestions would be greatly appreciated. Thank you.

A very common use case in our iOS app is that users take a large number of pictures (about 30) in low-light conditions using the camera app, and immediately after, they try to upload them to our servers. We measured the time to load photos from the PHPickerResult. For most photos, it takes less than 100 milliseconds, but for some of them, it takes several seconds—we even saw minutes in some extreme cases. We believe this started happening with iOS 17, when deferred photo processing was introduced. If users take the pictures using our in-app camera experience, the options to customize the camera are enough to avoid the long waiting times. However, the majority of our users still prefer to take the photos with the camera app, and there is little we can do about that. In the past few weeks, we tried many combinations: Without asking for permissions, we tried loadFileRepresentation, loadData, and loadObject. We explored the PHImageManager route, asking permissions and with different options for deliveryMode, resizeMode, version, isSynchronous, and allowSecondaryDegradedImage. We also tried fetching the photos in parallel, with very bad results. In summary, nothing helped the long waiting times—minutes in some cases. The first question is then, is there anything we can do to ignore the post-processing of the photos and get them fast? We could accept the unprocessed images. At a minimum, we would like to show our users what we are doing and why we are taking so much time. We tried to load thumbnails with loadPreviewImage and put a progress indicator on top. This method consistently gives us an error for all photos: (lldb) p error.localizedDescription (String) "Cannot load preview." We can load thumbnails with the PHImageManager option, but it seems excessive to need to get permissions only for that. Second question would be then, what can we do to load thumbnails without asking for permission? I created a feedback report with a video and sample code to reproduce -> FB15493683

Dear Senior Developer, I come to you at a time where I am lost. Over the last 2-3 months, I have noticed a series of crashes occuring on my app. This all started randomly and has now been a regular occurence. Usually, I would receive some detail as it relates to some class or view that is causing this error but now the only details I have is it relates to a UiViewController dealloc even though I am using SwiftUI. Below I have attached the stack trace from firebase crash analytics. I have spent months on this and I am asking for the help of someone much more senior and knowledable to assist me in this regard. Thanks again for your help and I await your response. I am also willing to share my screen LIVE to help you help me identify this issue. manny.GoblinTools_issue_bfd18ee65a92b459d4ecef3475a9ec34_crash_session_032166c28b8c4764b13a6fdca636d2d6_DNE_0_v2_stacktrace.txt

We have widgets in our app. We're now working on a Live Activitiy with a button calling an app intent. This app intent needs to update our Widgets, and we're seeing semi-great results. When we're updating the widgets from within the app, it works great. Also from geofence triggers it usually works, so we're thinking it might have to do with the "widget update budget"? According to the docs: Cases in which WidgetKit doesn’t count reloads against your widget’s budget include when: The widget performs an app intent, such as when the user taps a button or toggles a switch. But we're not really seeing that. When I run our app from within Xcode, everything runs great all the time and the widget gets updated within milliseconds, but when running the TestFlight version is more spotty. To be clear: This is a button in a live activity, calling an app intent, and in turn, the app intent is calling reloadAllTimelines for our "regular" widgets. The live activity itself always gets updated properly. My question is basically, am I doing something wrong and can I do something to increase the consistency of the widget updating on time? Abbreviated example: final class UserEventIntent: NSObject, LiveActivityIntent { @MainActor func perform() async throws -> some IntentResult { do { let newStatus: (stat: Status, wasSame: Bool) = try await eventHelper.performEvent(status: status) WidgetCenter.shared.reloadAllTimelines() }catch { await WidgetCenterBridge.updateLiveActivityForInProgress(false) } return .result() }
