Please excuse my lack of understanding of what are probably fundamental concepts in iOS/iPadOS development but I have searched far and wide for documentation and haven't had much luck so far. I am not sure that what I want to do is even possible with an iPad iPadOS app. Goals: Develop a Swift iPadOS app that can digitally sign a file using a PIV SmartCard/Token (Personal Identity Verification Card): Insert a PIV SmartCard/Token (such as a Yubikey 5Ci) into the lightning port of an iPadOS device iPad (NOT MacOS) Interface with the SmartCard/Token to access the user's PIV certificate/signature and "use it" to sign a file Question 1: How to get the PIV Certificate from SmartCard/Token/Yubikey into iPadOS keychain?   * Do we need to get the PIV certificate into the iOS keychain? Is there another way to interact with a SmartCard directly?   * This should prompt the user for their PIN? Question 2: How to get our Swift app to hook into the event that the SmartCard/Token is inserted into the device and then interface with the user's certificate?   * When is the user prompted to enter their PIN for SmartCard/Token/Yubikey?   * Do we need to use CyrptoTokenKit to interface with a smartcard inserted into the lightning port of an iOS device?

After porting code to Swift 6 (Xcode 16.4), I get a consistent crash (on simulator) when using UNUserNotificationServiceConnection It seems (searching on the web) that others have met the same issue. Is it a known Swift6 bug ? Or am I misusing UNUserNotification ? I do not have the crash when compiling on Xcode 26 ß5, which hints at an issue in Xcode 16.4. Crash log: Thread 10 Queue : com.apple.usernotifications.UNUserNotificationServiceConnection.call-out (serial) As far as I can tell, it seems error is when calling nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) I had to declare non isolated to solve a compiler error. Main actor-isolated instance method 'userNotificationCenter(_:didReceive:withCompletionHandler:)' cannot be used to satisfy nonisolated requirement from protocol 'UNUserNotificationCenterDelegate' I was advised to: Add 'nonisolated' to 'userNotificationCenter(_:didReceive:withCompletionHandler:)' to make this instance method not isolated to the actor I filed a bug report: Aug 10, 2025 at 2:43 PM – FB19519575

Hello everyone, I'm working on an app that uses WKWebView. My app uses a custom menu and we disable the default menu by overriding with: WKWebAction.canPerformAction() However, with the new iOS 18.2 release, I am no longer able to override the "Copy Link with Highlight" option that pops up when highlighting a selection as can be seen from the screenshot: Has anyone found a work around/bypass for this? Environment iOS Version: iOS 18.2 Device: iPhone 13 Pro App platform: iOS Xcode version: 16.1 MacOS: 14.5

Dear Apple Support, We are encountering an issue with deep linking on iOS 26 when using Safari and App Store redirection. Below are the detailed steps to reproduce the problem: The app is not installed on the device. User clicks on a Branch link: For example:- https://qewed.app.link/99u88ef9f?uuid=88dbwh5ubd4b Safari opens and displays the fallback page. User taps on “Get the App”, which navigates to the App Store. User installs and opens the app. Expected Behavior:
The app should receive the Branch link parameters (in this case, uuid=88dbwh5ubd4b) upon first open. Actual Behavior:
The app opens successfully, but the uuid parameter is not passed to the app. This issue seems specific to the Safari → App Store → App flow on iOS 26, as other flows behave correctly. Could you please advise whether this is a known issue or if there are recommended adjustments on our side to ensure parameters are consistently delivered after App Store redirection? Note: We are using Branch SDK version 3.11.0 (Cocoapods dependency) Thank you for your assistance.

Hello, Environment macOS 15.6.1 / Xcode 26 beta 7 / iOS 26 Beta 9 In a simple AVFoundation video-playback sample, I’m seeing different behavior between iOS 18 and iOS 26 regarding AVPlayerItem.didPlayToEndTimeNotification. I’ve attached a minimal sample below. Please replace videoURL with a valid short video URL. Repro steps Tap “Play” to start playback and let the video finish. The AVPlayerItem.didPlayToEndTimeNotification registered with NotificationCenter should fire, and you should see Play finished. in the console. Without relaunching, tap “Play” again. This is where the issue arises. Observed behavior On iOS 18 and earlier: The video does not play again (it does not restart from the beginning), but AVPlayerItem.didPlayToEndTimeNotification is posted and Play finished. appears in the console. The same happens every time you press “Play”. On iOS 26: Pressing “Play” does not post AVPlayerItem.didPlayToEndTimeNotification. The code path that prints Play finished. is never called (the callback enclosing that line is not invoked again). Building the same program with Xcode 16.4 and running it on an iOS 26 beta device shows the same phenomenon, which suggests there has been a behavioral change for AVPlayerItem.didPlayToEndTimeNotification on iOS 26. I couldn’t find any mention of this in the release notes or API Reference. Because the semantics around AVPlayerItem.didPlayToEndTimeNotification appear to differ, we’re forced to adjust our logic. If there is a way to achieve the iOS 18–style behavior on iOS 26, I would appreciate guidance. Alternatively, if this change is intentional, could you share the reasoning? Is iOS 26 the correct behavior from Apple’s perspective and iOS 18 (and earlier) behavior considered incorrect? Any official clarification would be extremely helpful. import UIKit import AVFoundation final class ViewController: UIViewController { private let videoURL = URL(string: "https://......mp4")! private var player: AVPlayer? private var playerItem: AVPlayerItem? private var playerLayer: AVPlayerLayer? private var observeForComplete: NSObjectProtocol? // UI private let playerContainerView = UIView() private let playButton = UIButton(type: .system) private let stopButton = UIButton(type: .system) private let replayButton = UIButton(type: .system) deinit { if let observeForComplete { NotificationCenter.default.removeObserver(observeForComplete) } } override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .systemBackground setupUI() setupPlayer() } override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() playerLayer?.frame = playerContainerView.bounds } // MARK: - Setup private func setupUI() { playerContainerView.translatesAutoresizingMaskIntoConstraints = false playerContainerView.backgroundColor = .black view.addSubview(playerContainerView) // Buttons playButton.setTitle("Play", for: .normal) stopButton.setTitle("Pause", for: .normal) replayButton.setTitle("RePlay", for: .normal) [playButton, stopButton, replayButton].forEach { $0.titleLabel?.font = .systemFont(ofSize: 16, weight: .semibold) $0.translatesAutoresizingMaskIntoConstraints = false $0.contentEdgeInsets = UIEdgeInsets(top: 10, left: 16, bottom: 10, right: 16) } let stack = UIStackView(arrangedSubviews: [playButton, stopButton, replayButton]) stack.axis = .horizontal stack.spacing = 16 stack.alignment = .center stack.distribution = .equalCentering stack.translatesAutoresizingMaskIntoConstraints = false view.addSubview(stack) NSLayoutConstraint.activate([ playerContainerView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 20), playerContainerView.leadingAnchor.constraint(equalTo: view.leadingAnchor), playerContainerView.trailingAnchor.constraint(equalTo: view.trailingAnchor), playerContainerView.heightAnchor.constraint(equalToConstant: 200), stack.topAnchor.constraint(equalTo: playerContainerView.bottomAnchor, constant: 20), stack.centerXAnchor.constraint(equalTo: view.centerXAnchor) ]) // Action playButton.addTarget(self, action: #selector(didTapPlay), for: .touchUpInside) stopButton.addTarget(self, action: #selector(didTapStop), for: .touchUpInside) replayButton.addTarget(self, action: #selector(didTapReplayFromStart), for: .touchUpInside) } private func setupPlayer() { // AVURLAsset -> AVPlayerItem → AVPlayer let asset = AVURLAsset(url: videoURL) let item = AVPlayerItem(asset: asset) self.playerItem = item let player = AVPlayer(playerItem: item) player.automaticallyWaitsToMinimizeStalling = true self.player = player let layer = AVPlayerLayer(player: player) layer.videoGravity = .resizeAspect playerContainerView.layer.addSublayer(layer) layer.frame = playerContainerView.bounds self.playerLayer = layer // Notification if let observeForComplete { NotificationCenter.default.removeObserver(observeForComplete) } if let playerItem { observeForComplete = NotificationCenter.default.addObserver( forName: AVPlayerItem.didPlayToEndTimeNotification, object: playerItem, queue: .main ) { [weak self] _ in guard self != nil else { return } Task { @MainActor in print("Play finished.") } } } } // MARK: - Actions @objc private func didTapPlay() { player?.play() } @objc private func didTapStop() { player?.pause() } // RePlay @objc private func didTapReplayFromStart() { player?.seek(to: .zero, toleranceBefore: .zero, toleranceAfter: .zero) { [weak self] _ in self?.player?.play() } } } I would greatly appreciate an official response from Apple engineering on whether this is an intentional change, a regression, or an API contract clarification, and what the recommended approach is going forward. Thank you.

(Sorry if this is not the right place to post...) I upgraded my iPad / macOS to 26 yesterday. Soon, I noticed that the two buttons in the toolbar would sometimes not appear: Note that they should be visible at all times. I played a little more to see if there was any pattern, but I could not find any. Has anyone experienced something similar...? Is this an iPadOS26 bug? (I haven't checked with an iPhone yet.) Thanks.

Hello I want to implement customisation to swift argumentparser, Here are following changes want to do it in my cli changing default footer present in help command output currently help command output coming like this OVERVIEW: clisample USAGE: clisample <subcommand> OPTIONS: --version show the version. -h, --help show the help. SUBCOMMANDS: logs (default) Export logs for clisample processes. See 'clisample --help' for more information.' so instead of See 'clisample --help' for more information.' I want my own string For more details, run 'clisample help <subcommand>' customise error string getting from validation error Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> See 'clisample logs --help' for more information. so I want error output with example and customised footer, like this Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> Example: clisample logs -t 5m For more details, run 'clisample help <subcommand>' Is this changes possible from anyway?

In WWDC25 video 284: Build a UIKit app with the new design, there is mention of a cornerConfiguration property on UIVisualEffectView. But this properly isn't documented and Xcode 26 isn't aware of any such property. I'm trying to replicate the results of that video in the section titled Custom Elements starting at the 19:15 point. There is a lot of missing details and typos in the code associated with that video. My attempts with UIGlassEffect and UIViewEffectView do not result in any capsule shapes. I just get rectangles with no rounded corners at all. As an experiment, I am trying to recreate the capsule with the layers/location buttons in the iOS 26 version of the Maps app. I put the following code in a view controller's viewDidLoad method let imgCfgLayer = UIImage.SymbolConfiguration(hierarchicalColor: .systemGray) let imgLayer = UIImage(systemName: "square.2.layers.3d.fill", withConfiguration: imgCfgLayer) var cfgLayer = UIButton.Configuration.plain() cfgLayer.image = imgLayer let btnLayer = UIButton(configuration: cfgLayer, primaryAction: UIAction(handler: { _ in print("layer") })) var cfgLoc = UIButton.Configuration.plain() let imgLoc = UIImage(systemName: "location") cfgLoc.image = imgLoc let btnLoc = UIButton(configuration: cfgLoc, primaryAction: UIAction(handler: { _ in print("location") })) let bgEffect = UIGlassEffect() bgEffect.isInteractive = true let bg = UIVisualEffectView(effect: bgEffect) bg.contentView.addSubview(btnLayer) bg.contentView.addSubview(btnLoc) view.addSubview(bg) btnLayer.translatesAutoresizingMaskIntoConstraints = false btnLoc.translatesAutoresizingMaskIntoConstraints = false bg.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ btnLayer.leadingAnchor.constraint(equalTo: bg.contentView.leadingAnchor), btnLayer.trailingAnchor.constraint(equalTo: bg.contentView.trailingAnchor), btnLayer.topAnchor.constraint(equalTo: bg.contentView.topAnchor), btnLoc.centerXAnchor.constraint(equalTo: bg.contentView.centerXAnchor), btnLoc.topAnchor.constraint(equalTo: btnLayer.bottomAnchor, constant: 15), btnLoc.bottomAnchor.constraint(equalTo: bg.contentView.bottomAnchor), bg.centerXAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerXAnchor), bg.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 40), ]) The result is pretty close other than the complete lack of capsule shape. What changes would be needed to get the capsule shape? Is this even the proper approach?

I have some logic which requires NFC support on the device. This is what I'm using to make sure that it's available: isNFCMissing = !NFCNDEFReaderSession.readingAvailable && !NFCTagReaderSession.readingAvailable && !NFCVASReaderSession.readingAvailable Is it possible for isNFCMissing to be true even if the device has an NFC chip. The minimum iOS version for the application is 16 which is only supported on devices with an NFC chip to begin with.

I downloaded the file through Scoot, and when I remove VisionPro, the app will call the StreamDelegate method and return ". endEncountered". How can I solve this problem? Thank you！

I am an SDK provider working with Swift Package Manager (SPM) to deliver libraries for iOS developers. My SDK currently uses SPM targets to modularize functionality. However, SPM enforces strict resource bundling, which prevents me from efficiently offering multiple targets—each with a different set of localization files—in a single package. Current Limitation: When multiple SPM targets share the same source and resource directory but require distinct sets of .lproj localization folders (for app size or client requirements), SPM raises “overlapping sources” errors. The only workaround is to manually split resource directories or have clients prune localizations post-build, which is inefficient and error-prone. Feature Request: Please consider adding native support in Swift Package Manager for: Defining multiple targets within a single package that can process overlapping source/resource directories, Each target specifying a distinct subset of localization resource files via the exclude or a new designated parameter, Enabling efficient modular delivery of SDKs to clients needing different localization payloads, without redundant resource duplication or error-prone manual pruning. Support for this feature would greatly ease SDK distribution, lower app sizes, and improve package maintainability for iOS and all Swift platforms.

I have been banging my head against this problem for a bit now. I am trying to build a bidirectional, infinitely scrolling list that implements these core requirements: Loads data up/down on the fly as the user scrolls Preserves scroll velocity as the list is updated Restores the scroll to the exact visual location after data has changed Ensures no flicker when restoring scroll position - the user cannot know the list has updated and should continue scrolling as normal Because LazyVStack does not play well with animations, I am opting to go with VStack and am implementing my own sliding window for data. This means that data can be removed as well as added, and a simple application of a height delta is not enough when restoring position. So far I have tried many things: Relying on ScrollPosition - simply does not work by itself as described (swift UI trying to keep the position stable with ID's) Relying on ScrollPosition.scrollTo - only kind of works with ID, no way to restore position with pixel perfect accuracy Intercepting the UIKit scrollView instance, using it to record and access the top row's position, mutating data and then queuing a scroll restoration using CATransaction.setCompletionBlock - this is the closest I've come, and it satisfies the top 3 requirements but sometimes I get a flicker on slightly heavier lists What I would really like, is a way of using ScrollView and granularly hooking into the lifecycle of the view after layout, and just before draw. At this point I would update the relevant scroll positions, and allow draw to continue. Is this possible? My knowledge is very limited at this point, but I believe I may be able to achieve something of the sort by swizzling layerWillDraw? Does this make sense, and is it prudent? In general, I'm very interesting in hearing what people have to say about the above, as well as this problem in general.

I’m trying to keep a specific row visually stable while the data backing a ScrollView changes. Goal 1. Before updating model.items, capture the top row’s offset relative to the scroll view. 2. Mutate the observable state so SwiftUI recomputes layout — but don’t draw yet. 3. Read the new layout, compute the delta, and adjust the scroll position so the previously visible row stays put. 4. Only then draw the new frame. Reduced example @Observable final class SomeModel { var items: [SomeItem] = [/* ... */] } struct MyBox: View { @Environment(SomeModel.self) private var model var body: some View { ScrollView { VStack { ForEach(model.items, id: \.id) { item in Color.red.frame(height: randomStableHeight(for: item.id)) } } } } } // Elsewhere: let oldRow = recordOldRow() // capture the row to stabilize model.items = generateNewItems() // mutate model (invalidates layout) let newPos = capturePreviousRowNewPosition(oldRow) // read new layout? restoreScrollPosition() // adjust so oldRow stays visually fixed // draw now Is that pipeline achievable in SwiftUI? If not, what’s the supported way to keep a row visually stable while the list updates?

iOS Development environment Xcode 16.4, macOS 15.6.1 (24G90) Run-time configuration: iOS 17.2+ Short Description After having successfully established an NWConnection (either as UDP or TCP), and subsequently receiving the error code: UDP Connection failed: 57 The operation couldn't be completed. (Network.NWError error 57 - Socket is not connected), available Interfaces: [enO] via NWConnection.stateUpdateHandler = { (newState) in ... } while newState == .failed the data connection does not restart by itself once cellular (RF) telephony coverage is established again. Detailed Description Context: my app has a continuous cellular data connection while in use. Either a UDP or a TCP connection is established depending on the user settings. The setup data connection works fine until the data connection gets disconnected by loss of connection to a available cellular phone base station. This disconnection simply occurs in very poor UMTS or GSM cellular phone coverage. This is totally normal behavior in bad reception areas like in mountains with signal loss. STEPS TO REPRODUCE Pre-condition App is running with active data connection. Action iPhone does loss the cellular data connection previously setup. Typically reported as network error code 57. Observed The programmed connection.stateUpdateHandler() is called in network connection state '.failed' (OK). The self-programmed data re-connection includes: a call to self.connection.cancel() a call to self.setupUDPConnection() or self.setupConnection() depending on the user settings to re-establish an operative data connection. However, the iPhone's UMTS/GSM network data (re-)connection state is not properly identified/notified via NWConnection API. There's no further network state notification by means of NWConnection even though the iPhone has recovered a cellular data network. Expected The iPhone or any other means automatically reconnects the interrupted data connection on its own. The connection.stateUpdateHandler() is called at time of the device's networking data connection (RF) recovering, subsequently to a connection state failed with error code 57, as the RF module is continuously (independently from the app) for available telephony networks. QUESTION How to systematically/properly detect a cellular phone data network reconnection readiness in order to causally reinitialize the NWConnection data connection available used in app. Relevant code extract Setup UDP connection (or similarly setup a TCP connection) func setupUDPConnection() { let udp = NWProtocolUDP.Options.init() udp.preferNoChecksum = false let params = NWParameters.init(dtls: nil, udp: udp) params.serviceClass = .responsiveData // service type for medium-delay tolerant, elastic and inelastic flow, bursty, and long-lived connections connection = NWConnection(host: NWEndpoint.Host.name(AppConstant.Web.urlWebSafeSky, nil), port: NWEndpoint.Port(rawValue: AppConstant.Web.urlWebSafeSkyPort)!, using: params) connection.stateUpdateHandler = { (newState) in switch (newState) { case .ready: //print("UDP Socket State: Ready") self.receiveUDPConnection(). // data reception works fine until network loss break case .setup: //print("UDP Socket State: Setup") break case .cancelled: //print("UDP Socket State: Cancelled") break case .preparing: //print("UDP Socket State: Preparing") break case .waiting(let error): Logger.logMessage(message: "UDP Connection waiting: "+error.errorCode.description+" \(error.localizedDescription), available Interfaces: \(self.connection.currentPath!.availableInterfaces.description)", LoggerLevels.Error) break case .failed(let error): Logger.logMessage(message: "UDP Connection failed: "+error.errorCode.description+" \(error.localizedDescription), available Interfaces: \(self.connection.currentPath!.availableInterfaces.description)", LoggerLevels.Error) // data connection retry (expecting network transport layer to be available) self.reConnectionServer() break default: //print("UDP Socket State: Waiting or Failed") break } self.handleStateChange() } connection.start(queue: queue) } Handling of network data connection loss private func reConnectionServer() { self.connection.cancel() // Re Init Connection - Give a little time to network recovery let delayInSec = 30.0. // expecting actually a notification for network data connection availability, instead of a time-triggered retry self.queue.asyncAfter(deadline: .now() + delayInSec) { switch NetworkConnectionType { case 1: self.setupUDPConnection() // UDP break case 2: self.setupConnection() // TCP break default: break } } } Does it necessarily require the use of CoreTelephony class CTTelephonyNetworkInfo or class CTCellularData to get notifications of changes to the user’s cellular service provider?

Hello everyone, I am experiencing a persistent authentication error when querying a custom user profile record, and the error message seems to be a red herring. My Setup: I have a custom CKRecord type called ColaboradorProfile. When a new user signs up, I create this record and store their hashed password, salt, nickname, and a custom field called loginIdentifier (which is just their lowercase username). In the CloudKit Dashboard, I have manually added an index for loginIdentifier and set it to Queryable and Searchable. I have deployed this schema to Production. The Problem: During login, I run an async function to find the user's profile using this indexed loginIdentifier. Here is the relevant authentication code: func autenticar() async { // ... setup code (isLoading, etc.) let lowercasedUsername = username.lowercased() // My predicate ONLY filters on 'loginIdentifier' let predicate = NSPredicate(format: "loginIdentifier == %@", lowercasedUsername) let query = CKQuery(recordType: "ColaboradorProfile", predicate: predicate) // I only need these specific keys let desiredKeys = ["password", "passwordSalt", "nickname", "isAdmin", "isSubAdmin", "username"] let database = CKContainer.default().publicCloudDatabase do { // This is the line that throws the error let result = try await database.records(matching: query, desiredKeys: desiredKeys, resultsLimit: 1) // ... (rest of the password verification logic) } catch { // The error always lands here logDebug("Error authenticating with CloudKit: \(error.localizedDescription)") await MainActor.run { self.errorMessage = "Connection Error: \(error.localizedDescription)" self.isLoading = false self.showAlert = true } } } The Error: Even though my query predicate only references loginIdentifier, the catch block consistently reports this error: Error authenticating with CloudKit: Field 'createdBy' is not marked queryable. I know createdBy (the system creatorUserRecordID) is not queryable by default, but my query isn't touching that field. I already tried indexing createdBy just in case, but the error persists. It seems CloudKit cannot find or use my index for loginIdentifier and is incorrectly reporting a fallback error related to a system field. Has anyone seen this behavior? Why would CloudKit report an error about createdBy when the query is explicitly on an indexed, custom field? I'm new to Swift and I'm struggling quite a bit. Thank you,

(Using macOS 26 Beta 9 and Xcode 26 Beta 7) I am trying to support basic onDrop from a source app to my app. I am trying to get the closest "source" representation of a drag-and-drop, e.g. a JPEG file being dropped into my app shouldn't be converted, but stored as a JPEG in Data. Otherwise, everything gets converted into TIFFs and modern iPhone photos get huge. I also try to be a good app, and provide asynchronous support. Alas, I've been running around for days now, where I can now support Drag-and-Drop from the Finder, from uncached iCloud files with Progress bar, but so far, drag and dropping from Safari eludes me. My code is as follows for the onDrop support: Image(nsImage: data.image).onDrop(of: Self.supportedDropItemUTIs, delegate: self) The UTIs are as follows: public static let supportedDropItemUTIs: [UTType] = [ .image, .heif, .rawImage, .png, .tiff, .svg, .heic, .jpegxl, .bmp, .gif, .jpeg, .webP, ] Finally, the code is as follows: public func performDrop(info: DropInfo) -> Bool { let itemProviders = info.itemProviders(for: Self.supportedDropItemUTIs) guard let itemProvider = itemProviders.first else { return false } let registeredContentTypes = itemProvider.registeredContentTypes guard let contentType = registeredContentTypes.first else { return false } var suggestedName = itemProvider.suggestedName if suggestedName == nil { switch contentType { case UTType.bmp: suggestedName = "image.bmp" case UTType.gif: suggestedName = "image.gif" case UTType.heic: suggestedName = "image.heic" case UTType.jpeg: suggestedName = "image.jpeg" case UTType.jpegxl: suggestedName = "image.jxl" case UTType.png: suggestedName = "image.png" case UTType.rawImage: suggestedName = "image.raw" case UTType.svg: suggestedName = "image.svg" case UTType.tiff: suggestedName = "image.tiff" case UTType.webP: suggestedName = "image.webp" default: break } } let progress = itemProvider.loadInPlaceFileRepresentation(forTypeIdentifier: contentType.identifier) { url, _, error in if let error { print("Failed to get URL from dropped file: \(error)") return } guard let url else { print("Failed to get URL from dropped file!") return } let queue = OperationQueue() queue.underlyingQueue = .global(qos: .utility) let intent = NSFileAccessIntent.readingIntent(with: url, options: .withoutChanges) let coordinator = NSFileCoordinator() coordinator.coordinate(with: [intent], queue: queue) { error in if let error { print("Failed to coordinate data from dropped file: \(error)") return } do { // Load file contents into Data object let data = try Data(contentsOf: intent.url) Dispatch.DispatchQueue.main.async { self.data.data = data self.data.fileName = suggestedName } } catch { print("Failed to load coordinated data from dropped file: \(error)") } } } DispatchQueue.main.async { self.progress = progress } return true } For your information, this code is at the state where I gave up and sent it here, because I cannot find a solution to my issue. Now, this code works everywhere, except for dragging and dropping from Safari. Let's pretend I go to this web site: https://commons.wikimedia.org/wiki/File:Tulip_Tulipa_clusiana_%27Lady_Jane%27_Rock_Ledge_Flower_Edit_2000px.jpg and I try to drag-and-drop the image, it will fail with the following error: URL https://upload.wikimedia.org/wikipedia/commons/c/cf/Tulip_Tulipa_clusiana_%27Lady_Jane%27_Rock_Ledge_Flower_Edit_2000px.jpg is not a file:// URL. And then, fail with the dreaded Failed to get URL from dropped file: Error Domain=NSItemProviderErrorDomain Code=-1000 As far as I can tell, the problem lies in the opaque NSItemProvider receiving a web site URL from Safari. I tried most solutions, I couldn't retrieve that URL. The error happens in the callback of loadInPlaceFileRepresentation, but also fails in loadFileRepresentation. I tried hard-requesting a loadObject of type URL, but there's only one representation for the JPEG file. I tried only putting .url in the requests, but it would not transfer it. Anyone solved this mystery?

Hi, My app was recently rejected with the following message: The app references non-public symbols in App: _BIO_s_socket, _OPENSSL_cleanse The confusing part is that these symbols do not come from iOS system libraries. They are defined inside a third-party static library (gRPC/OpenSSL) that my app links. I am not calling any Apple private API, only linking against the third-party code where those symbols are defined. Questions: Why does App Review treat these symbols as “non-public” when they are provided by my own bundled third-party library, not by the system? What is Apple’s recommended approach in this situation — should I rebuild the third-party library with symbol renaming / hidden visibility, or is there another supported method? It would help to understand the official reasoning here, because it seems strange that a vendor-namespaced or self-built OpenSSL would cause a rejection even though I am not using Apple’s internal/private APIs. Thanks for any clarification.

My app controls the cursor movement in a text view on iPhone and iPads. On screen touch, the IOS cursor position is out of sync with the app cursor position. Is there a way to find out, on screen touch, where the ios cursor positition is and update the app cursor to the ios cursor position? When they are out of sync, the user has to move the cursor to the startIndex and navigate from there. Frustating! I have looked at many programming books, forums, and internet search with nothing to no avail. Any help will be greatly appreciated. The app names are SummaGramPhonex and SummaGramIPAD11 and SummaGramIPAD13. Thanks. Charlie 3Sep25
