Overview

I was able to confirm with a customer of mine that calling copyfile with a source file that is a symbolic link on a NTFS partition always causes the error NSPOSIXErrorDomain 12 Cannot allocate memory They use NTFS drivers from Paragon. They tried copying a symbolic link from NTFS to both APFS and NTFS with the same result. Is this an issue with macOS, or with the NTFS driver? Copying regular files on the other hand always works. Copying manually from the Finder also seems to always work, both with regular files and symbolic links, so I'm wondering how the Finder does it. Here is the sample app that they used to reproduce the issue. The first open panel allows to select the source directory and the second one the destination directory. The variable filename holds the name of the symbolic link to be copied from the source to the destination. Apparently it's not possible to select a symbolic link directly in NSOpenPanel, as it always resolves to the linked file. @main class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ notification: Notification) { let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true openPanel.canChooseFiles = false openPanel.runModal() let filename = "Modules" let source = openPanel.urls[0].appendingPathComponent(filename) openPanel.runModal() let destination = openPanel.urls[0].appendingPathComponent(filename) do { let state = copyfile_state_alloc() defer { copyfile_state_free(state) } var bsize = UInt32(16_777_216) if copyfile_state_set(state, UInt32(COPYFILE_STATE_BSIZE), &bsize) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } if copyfile_state_set(state, UInt32(COPYFILE_STATE_STATUS_CB), unsafeBitCast(copyfileCallback, to: UnsafeRawPointer.self)) != 0 || copyfile_state_set(state, UInt32(COPYFILE_STATE_STATUS_CTX), unsafeBitCast(self, to: UnsafeRawPointer.self)) != 0 || copyfile(source.path, destination.path, state, copyfile_flags_t(COPYFILE_NOFOLLOW)) != 0 { throw NSError(domain: NSPOSIXErrorDomain, code: Int(errno)) } } catch { let error = error as NSError let alert = NSAlert() alert.messageText = "\(error.localizedDescription)\n\(error.domain) \(error.code)" alert.runModal() } } private let copyfileCallback: copyfile_callback_t = { what, stage, state, src, dst, ctx in if what == COPYFILE_COPY_DATA { if stage == COPYFILE_ERR { return COPYFILE_QUIT } var size: off_t = 0 copyfile_state_get(state, UInt32(COPYFILE_STATE_COPIED), &size) } return COPYFILE_CONTINUE } }

When I try to connect to a Wi-Fi network with iPhone16 (iOS18), the following pop-up appears. Please tell me the conditions under which this pop-up appears. Additionally, upon investigating the surrounding wireless signals, there were no other wireless devices on the same channel band." [Pop-up] Unable to join the network "〇〇〇〇" This network is operating on Wi-Fi channels in use by several other nearby networks. Restarting your wireless router may allow it to automatically choose the best channel to use, and may resolve this problem. Also, I can connect to a Wi-Fi network without any problems with iPhoneSE2 (iOS18). However, after displaying the above pop-up on iPhone16 (iOS18), when I try to connect to a Wi-Fi network with iPhoneSE2 (iOS18), the following pop-up appears.

I have a CALayer and I'd like to animate a property on it. But, the property that triggers the animation change is different to the one that is being changed. A basic example of what I'm trying to do is below. I'm trying to create an animation on count by changing triggerProperty. This example is simplified (in my project, the triggerProperty is not an Int, but a more complex non-animatable type. So, I'm trying to animate it by creating animations for some of it's properties that can be matched to CABasicAnimation - and rendering a version of that class based on the interpolated values). @objc class AnimatableLayer: CALayer { @NSManaged var triggerProperty: Int @NSManaged var count: Int override init() { super.init() triggerProperty = 1 setNeedsDisplay() } override init(layer: Any) { super.init(layer: layer) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override class func needsDisplay(forKey key: String) -> Bool { return key == String(keypath: \AnimatableLayer.triggerProperty) || super.needsDisplay(forKey: key) } override func action(forKey event: String) -> (any CAAction)? { if event == String(keypath: \AnimatableLayer.triggerProperty) { if let presentation = self.presentation() { let keyPath = String(keypath: \AnimatableLayer.count) let animation = CABasicAnimation(keyPath: keyPath) animation.duration = 2.0 animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear) animation.fromValue = presentation.count animation.toValue = 10 return animation } } return super.action(forKey: event) } override func draw(in ctx: CGContext) { print("draw") NSGraphicsContext.saveGraphicsState() let nsctx = NSGraphicsContext(cgContext: ctx, flipped: true) // create NSGraphicsContext NSGraphicsContext.current = nsctx // set current context let renderText = NSAttributedString(string: "\(self.presentation()?.count ?? self.count)", attributes: [.font: NSFont.systemFont(ofSize: 30)]) renderText.draw(in: bounds) NSGraphicsContext.restoreGraphicsState() } func animate() { print("animate") self.triggerProperty = 10 } } With this code, the animation isn't triggered. It seems to get triggered only if the animation's keypath matches the one on the event (in the action func). Is it possible to do something like this?

The update to IOS 18.1 broke my VPN app. It was still working with 18.0.1. First analysis indicates that packets are not received through packetflow. Postings like this also indicates that there has something changed about the routing: https://developer.apple.com/forums/thread/767315 So what is going on here? I am using the following NEPacketTunnelNetworkSettings: static private func buildSettings() -> NEPacketTunnelNetworkSettings { let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "127.0.0.1") let ipv4Settings = NEIPv4Settings(addresses: ["10.42.0.1"], subnetMasks: ["255.255.0.0"]) ipv4Settings.includedRoutes = [NEIPv4Route.default()] ipv4Settings.excludedRoutes = [] settings.ipv4Settings = ipv4Settings settings.mtu = 1500 let dnsSettings = NEDNSSettings(servers: ["10.42.0.1"]) settings.dnsSettings = dnsSettings let ipv6Settings = NEIPv6Settings.init(addresses: ["fdb2:d970:8536:8dc6:0000:0000:0000:0001"], networkPrefixLengths: [64]) ipv6Settings.includedRoutes = [NEIPv6Route.default()] settings.ipv6Settings = ipv6Settings return settings } Any help would be greatly appreciated.

I'm trying to add Cloud Kit integration to SwiftData app (that is already in the App Store, btw). When the app is installed on devices that are directly connected to Xcode, it works (a bit slow, but pretty well). But when the app is distributed to Testflight internal testers, the synchronization doesn't happen at all. So, is this situation normal and how can I test apps with iCloud integration properly?

Dear Apple Team, As an MDM (Mobile Device Management) service provider, we are writing to bring attention to an issue that is affecting many of our customers who manage large fleets of iOS devices. Specifically, we have encountered challenges with the app update process via MDM, which is impacting both kiosk devices and non-kiosk devices in a variety of use cases. Issue 1: App Updates Delayed on Kiosk Devices Many of our customers are deploying kiosk devices that are used 24/7 independently with no attendants. In these cases, when an app update is sent through MDM via the installApplication command, the installation does not begin immediately. Instead, the update starts only after the device is locked. However, since these kiosk devices are running continuously, they are rarely locked, preventing the app update from occurring. To force the update, administrators need to manually remote lock or physically lock the device, which is a time-consuming process. This becomes even more challenging for devices like Apple TV, where remotely locking and unlocking the device to complete app updates is especially difficult, making it hard to keep the apps up to date in a timely manner. Issue 2: User Cancellations of Critical Updates on Non-Kiosk Devices In the case of non-kiosk devices, customers are encountering another challenge: when a critical update is pushed during business hours, users are often prompted to install the update. However, many users tend to cancel the update, leaving devices unpatched and potentially vulnerable. This behavior can delay the deployment of important security patches, which is a critical concern for organizations managing sensitive data or business-critical apps. Request for a Solution Our customers have expressed the need for a more reliable and forceful app update mechanism. Specifically, we are requesting the following features to improve the app update experience: Scheduled app updates: The ability to schedule app updates, similar to the way OS updates are handled. If the user does not install the update within a specified timeframe, the update should begin automatically or prompt the user with a stronger reminder. Force install option: A feature that would allow MDM administrators to force an app update immediately, without relying on user intervention. This would ensure that critical updates are installed promptly, improving security and system stability across all devices. These features are essential for many of our customers who rely on timely and consistent app updates to maintain security, functionality, and compliance across their managed devices. Without these options, they face challenges in ensuring devices are kept up-to-date, which can result in security vulnerabilities and operational disruptions. We kindly request that Apple consider adding these functionalities to improve the MDM app update process and provide a more reliable experience for both kiosk and non-kiosk device management. Thank you for your attention to this matter. We look forward to your feedback and any potential improvements in future iOS updates. Raised in the same manner as feedback: FB15910292

This is Saeid from Drion.ai Ag company in Germany. We are s marketing startup and we are developing a marketing platform we need to give opportunity to our users to sign in using Apple ID. I have sent all of the company documents, my ID card, and all documents that we have in our company just to activate the AppID login API and it is nothing after more than 2 months. I had a call from Apple support and she told me to send some documents I did it, but nothing yet. Is this Apple company's suport for developers?!

I am currently working on a Visual Basic .NET project and aim to integrate an internal application with the Apple Business Manager API to access DEP (Device Enrollment Program) device data. Specifically, I would like to request any guidance on the following aspects: Generating a Valid Access Token: I am aware that JSON tokens are required to interact with the API, but I am unsure of the correct procedure to create a valid token for accessing the Apple Business Manager data. How to set permissions for accessing DEP Device Data: What steps do I need to follow to obtain the necessary permissions to read DEP device data from Apple Buiness Manager? Are there specific configurations or approval processes that need to be completed within Apple Developer Account oder Apple Business Manager account (which both uses same Apple ID)? API Endpoints and Documentation to access Business Manager by API: Could you please point me to the relevant APIs and endpoints for interacting with the DEP data? Which web requests to send where? Any documentation that outlines the API structure fur Business Manager access and how and where to obtain access tokens for it. Thanks for any assistance as I stuck here since it is ma first project accessing Apple APIs.

I am trying to port SceneKit projects to Swift 6, and I just can't figure out how that's possible. I even start thinking SceneKit and Swift 6 concurrency just don't match together, and SceneKit projects should - hopefully for the time being only - stick to Swift 5. The SCNSceneRendererDelegate methods are called in the SceneKit Thread. If the delegate is a ViewController: class GameViewController: UIViewController { let aNode = SCNNode() func renderer(_ renderer: any SCNSceneRenderer, updateAtTime time: TimeInterval) { aNode.position.x = 10 } } Then the compiler generates the error "Main actor-isolated instance method 'renderer(_:updateAtTime:)' cannot be used to satisfy nonisolated protocol requirement" Which is fully understandable. The compiler even tells you those methods can't be used for protocol conformance, unless: Conformance is declare as @preconcurrency SCNSceneRendererDelegate like this: class GameViewController: UIViewController, @preconcurrency SCNSceneRendererDelegate { But that just delays the check to runtime, and therefore, crash in the SceneKit Thread happens at runtime... Again, fully understandable. or the delegate method is declared nonisolated like this: nonisolated func renderer(_ renderer: any SCNSceneRenderer, updateAtTime time: TimeInterval) { aNode.position.x = 10 } Which generates the compiler error: "Main actor-isolated property 'position' can not be mutated from a nonisolated context". Again fully understandable. If the delegate is not a ViewController but a nonisolated class, we also have the problem that SCNNode can't be used. Nearly 100% of the SCNSceneRendererDelegate I've seen do use SCNNode or similar MainActor bound types, because they are meant for that. So, where am I wrong ? What is the solution to use SceneKit SCNSceneRendererDelegate methods with full Swift 6 compilation ? Is that even possible for now ?

Hi, Our team uses Xcode Cloud to run unit tests, and since around November, we’ve been frequently experiencing timeouts with the following type of process: @Test func hogeTest() async { // do something hoge.do() // wait until done await wait(condition: { hoge.isDone }) // test result #expect(hoge.isSucceeded) } private func wait(condition: () async -> Bool, timeout: TimeInterval = 0.5, pollingInterval: TimeInterval = 0.01) async throws { let deadline = Date().addingTimeInterval(timeout) while Date() < deadline { if await condition() { return } try await Task.sleep(nanoseconds: UInt64(round(pollingInterval * TimeInterval(NSEC_PER_SEC)))) } Issue.record("timeout") } Although sleep is supposed to wait for only a few milliseconds, there are cases where it takes more than 10 seconds, leading to a timeout. What could be causing this instability in the sleep duration? Additionally, if there are other recommended ways to implement polling and waiting in Swift Testing, I would appreciate it if you could share them. A feedback report (FB15899163) has already been submitted. Best regards,

Our app monitors device usage and applies a shield when the set time limit is reached. Multiple DeviceActivitySchedules can be present, each with different time limits. To display notifications at 50% of the total limit for each DeviceActivitySchedule, we set a warning time at half of the total time. However, we occasionally receive premature event callbacks. For example, consider a schedule from 13:00 to 13:30 with a single event threshold at 10 minutes and a warning time of 5 minutes. The 'eventDidReachThreshold' callback is delivered prematurely, along with the 'eventWillReachThresholdWarning' callback, at 13:10. Additionally, in some cases, when one DeviceActivitySchedule ends and the next begins immediately, DeviceActivityEvents registered for the new DeviceActivitySchedule are delivered prematurely along with the schedule start callback. For example, consider there are two DeviceActivitySchedules from 12:00 to 13:00 and from 13:00 to 14:00, each with a limit of 10 minutes and a warning time of 5 minutes. When the first schedule ends and the next begins at 13:00, the 'eventDidReachThreshold' callbacks for the events registered in the second schedule are delivered prematurely, along with the 'intervalDidStart' callback.

Hi, How to customize tables in SwiftUI its color background for example, the background modifier doesn't work ? how to change separator lines ? rows background colors ? give header row different colors to its text and background color ? Kind Regards

Hi, It seems that on M4 devices any virtual machine with macOS version older than 13.4 fail to boot, they stuck with a black screen. This is regardless of the virtualization software used (UTM, VirtualBuddy, Viable, etc...). After talking to many people everyone experiences the same. At least for me, this is a massive limitation of the platform, I really hope this is a bug which can be fixed. Thanks, Csaba

Hi, I found when continuously predicting with the same Core ML model in 120 FPS will be faster than in 60 FPS. I use Macbook Pro M2 and turn on ProMotion to run Core ML model prediction with a 120 FPS video, the average prediction time is 7.46ms as below: But when I turn off ProMotion, set 60 Hz refresh rate, and run Core ML model prediction with a 60 FPS video, the average prediction time is 10.91ms as below: What could be the technical explanation for these results? Is there any documentation or technical literature that addresses this behavior?

Hello Apple Developer Team, I am facing an issue with remote notifications in my iOS app. When the app is in a terminated (kill) state, notifications are successfully received by the device, but none of the app's handlers (like _firebaseMessagingBackgroundHandler in Flutter) are invoked. This is impacting our ability to process silent notifications or perform background tasks reliably when the app is not running. Steps to reproduce: Send a remote notification with content-available: 1 in the payload. Confirm the notification is received by the device while the app is in kill mode. Observe that no background or foreground notification methods are triggered in the app. Expected Behavior: The app should invoke the background handler to process the notification payload, even in a terminated state. Observed Behavior: The notification is delivered to the device, but no app-level processing occurs because none of the methods are triggered. Can you please confirm if this is the intended behavior due to iOS limitations, or if there is a configuration or alternative solution to allow background handlers to execute in such scenarios? Any guidance or clarification would be highly appreciated. Thank you!

I have followed https://apple.github.io/coremltools/docs-guides/source/installing-coremltools.html but failed. Looks like the doc is too outdated.

I have an app with the following model: @Model class TaskList { @Attribute(.unique) var name: String // Relationships var parentList: TaskList? @Relationship(deleteRule: .cascade, inverse: \TaskList.parentList) var taskLists: [TaskList]? init(name: String, parentTaskList: TaskList? = nil) { self.name = name self.parentList = parentTaskList self.taskLists = [] } } If I run the following test, I get the expected results - Parent has it's taskLists array updated to include the Child list created. I don't explicitly add the child to the parent array - the parentList relationship property on the child causes SwiftData to automatically perform the append into the parent array: @Test("TaskList with children with independent saves are in the database") func test_savingRootTaskIndependentOfChildren_SavesAllTaskLists() async throws { let modelContext = TestHelperUtility.createModelContext(useInMemory: false) let parentList = TaskList(name: "Parent") modelContext.insert(parentList) try modelContext.save() let childList = TaskList(name: "Child") childList.parentList = parentList modelContext.insert(childList) try modelContext.save() let fetchedResults = try modelContext.fetch(FetchDescriptor<TaskList>()) let fetchedParent = fetchedResults.first(where: { $0.name == "Parent"}) let fetchedChild = fetchedResults.first(where: { $0.name == "Child" }) #expect(fetchedResults.count == 2) #expect(fetchedParent?.taskLists.count == 1) #expect(fetchedChild?.parentList?.name == "Parent") #expect(fetchedChild?.parentList?.taskLists.count == 1) } I have a subsequent test that deletes the child and shows the parent array being updated accordingly. With this context in mind, I'm not seeing these relationship updates being observed within SwiftUI. This is an app that reproduces the issue. In this example, I am trying to move "Finance" from under the "Work" parent and into the "Home" list. I have a List that loops through a @Query var taskList: [TaskList] array. It creates a series of children views and passes the current TaskList element down into the view as a binding. When I perform the operation below the "Finance" element is removed from the "Work" item's taskLists array automatically and the view updates to show the removal within the List. In addition to that, the "Home" item also shows "Finance" within it's taskLists array - showing me that SwiftData is acting how it is supposed to - removed the record from one array and added it to the other. The View does not reflect this however. While the view does update and show "Finance" being removed from the "Work" list, it does not show the item being added to the "Home" list. If I kill the app and relaunch I can then see the "Finance" list within the "Home" list. From looking at the data in the debugger and in the database, I've confirmed that SwiftData is working as intended. SwiftUI however does not seem to observe the change. ToolbarItem { Button("Save") { list.name = viewModel.name list.parentList = viewModel.parentTaskList try! modelContext.save() dismiss() } } To troubleshoot this, I modified the above code so that I explicitly add the "Finance" list to the "Home" items taskLists array. ToolbarItem { Button("Save") { list.name = viewModel.name list.parentList = viewModel.parentTaskList if let newParent = viewModel.parentTaskList { // MARK: Bug - This resolves relationship not being reflected in the View newParent.taskLists?.append(list) } try! modelContext.save() dismiss() } } Why does my explicit append call solve for this? My original approach (not manually updating the arrays) works fine in every unit/integration test I run but I can't get SwiftUI to observe the array changes. Even more strange is that when I look at viewModel.parentTaskList.taskLists in this context, I can see that the list item already exists in it. So my code effectively tries to add it a second time, which SwiftData is smart enough to prevent from happening. When I do this though, SwiftUI observes a change in the array and the UI reflects the desired state. In addition to this, if I replace my custom list rows with an OutlineGroup this issue doesn't manifest itself. SwiftUI stays updated to match SwiftData when I remove my explicit array addition. I don't understand why my views, which is passing the TaskList all the way down the stack via Bindable is not updating while an OutlineGroup does. I have a complete reproducible ContentView file that demonstrates this as a Gist. I tried to provide the source here but it was to much for the post. One other anecdote. When I navigate to the TaskListEditorScreen and open the TaskListPickerScreen I get the following series of errors: error: the replacement path doesn't exist: "/var/folders/07/3px_03md30v9n105yh3rqzvw0000gn/T/swift-generated-sources/@_swiftmacro_09SwiftDataA22UIChangeDetectionIssue20TaskListPickerScreenV9taskLists33_A40669FFFCF66BB4EEA5302BB5ED59CELL5QueryfMa.swift" I saw another post regarding these and I'm wondering if my issue is related to this. So my question is, do I need to handle observation of SwiftData models containing arrays differently in my custom views? Why do bindings not observe changes made by SwiftData but they observe changes made explicitly by me?
