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.

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 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?

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?

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 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. I have notice that don't call this framework when iOS version less than iOS 18, my code control like API_AVAILABLE(ios(18.0)) or @available(iOS 18.0, *)). I try that set "Build Phases" -> Embed Framework -> Copy only when installing -> ON, it is okay on iOS 17.6, but it is not work on iOS 18. My framework in here: https://github.com/MingJieHan/HansTranslation My question that how to do? first way that change option for HansTranslation.framework, let it not link Translation_SwiftUI automatically, not success. second way that change my app option, let it not check library, I don't know how to do next step. please help me or give me some idea for those. Thanks.

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 am working with Selenium but after upgrading to Sequoia 1.0.1, my testing tool is not Lon get working for safari. I checked following file exits: /usr/bin/safaridriver and it is no there

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)

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.

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!

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.

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.

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.

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! 😊

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".

Setting bundle data(pList)is not displaying under our app after iPadOS 18 upgrade.  Before the iPadOS upgrade the settings was appearing in the app setting sections. Setting section is broken after the iPadOS 18 upgrade. Is this the known issue and how do we get the setting section back?

In the company that I work we have a huge app and we have implemented an image annotation feature using the QLPreviewController but there is a bug where even with an OOTB implementation of the QLPreviewController, when I add a text, change the colour of that text and then double click on the text to edit it, it reverts back to black. I tried the same implementation in a sample app but I couldn't reproduce the bug hence it is not a bug with the library but something with the app interacting with the library. I was wondering if anyone can provide any suggestion with what the reason may be, as sadly I cannot provide any code examples as that would break company code. From my research what I found strange is that when I double click the coloured text and it goes to black, then undo it its as if that was not a recorded event as the undo goes back to the step before the text was coloured meaning it replaces the colour changing event rather than recording it as a new event that can be undone. If any has any suggestion please help me as I am quite stuck. 🙏
