Overview

We integrated DeviceCheck framework into our app to prevent fraudulent call to our app service around one year ago. Recently, we received a few cases related to this function over Christmas Eve period. Based on the logs we have, it indicated both the following two functions returned errors. But we don't have the exactly errors logged and now we cannot replicate. DCAppAttestService.shared.attestKey() DCAppAttestService.shared.generateAssertion() The other finding we have is some users reporting this issue recently upgraded their devices from iOS 18 to iOS 26. So we are suspecting it's due to either the OS upgrading, or Apple's app attest service degrading. Anyone encountered the similar issues before, or have any idea regarding the root cause? Thanks!

Hi all, I’m building an iOS app that uses CoreNFC to communicate with a YubiKey 5C NFC over ISO14443 / ISO7816 and send APDUs (e.g. select an applet by AID). Environment • Device: iPhone 13 Pro Max • iOS: 18.6.2 • Xcode: 26.1.1 (17B100) • API: NFCTagReaderSession(pollingOption: .iso14443) using NFCTag.iso7816 What I’m trying to do 1. Start NFCTagReaderSession(.iso14443) 2. Detect tag → connect 3. Send ISO7816 APDUs (SELECT AID, etc.) Issue A — Entitlements / signing If I add ISO7816-related NFC entitlements, Xcode fails signing with an error like: • “Provisioning profile … doesn’t match entitlements file value for com.apple.developer.nfc.readersession.formats” When I inspect the generated .mobileprovision, I only see something like: • com.apple.developer.nfc.readersession.formats = [NDEF, TAG, PACE] …and I do not see an ISO7816 / select-identifiers entitlement (and the Developer portal UI doesn’t appear to let me enable it). Questions: 1. Is ISO7816 access under com.apple.developer.nfc.readersession.formats restricted and requires Apple approval? If yes, what’s the correct request process? 2. Is com.apple.developer.nfc.readersession.iso7816.select-identifiers required for sending ISO7816 APDUs? If yes, how do developers obtain it / enable it for an App ID + provisioning profiles? 3. What is the Apple-supported way to configure entitlements/profiles for CoreNFC ISO7816 APDU communication with a token like a YubiKey? Issue B — Runtime NFC error Separately (even when I can run), I intermittently/consistently get: • NFCError Code=104 (“Tag is not connected”) This occurs after the tag is detected/connected when trying to establish a session or send APDUs. I’ve verified: • No phone case interference • Correct placement • Consistent detection “tick” from the phone for "Ready to Scan" prompt after tapping YubiKey 5C NFC device. If helpful, I can share: • A minimal sample project • The exact entitlements I tried • Console logs around the Code 104 failure Thanks!

I've made my first app and encountered an unexpected (potentially existential) issue. The Manager app is designed to tag 3rd party "plugins" used by a DAW, storing metadata in a local SQLite database, and move them between Active and Inactive folders. This allows management of the plugin collection - the DAW only uses what's in the Active folder. Permissions are obtained via security-scoped bookmarks on first launch. The app functions as intended: plugin bundles move correctly and the database tracks everything. No information is written to the plugins themselves. The Problem:
When moving plugins using fs.rename() , the MAS sandbox automatically adds the com.apple.quarantine extended attribute to moved files. When the DAW subsequently rebuilds its plugin cache, it interprets quarantined plugins as "corrupt" or potentially malicious and refuses to load them. Technical Details: Moving files with NSFileManager or Node.js fs APIs within sandbox triggers quarantine Sandboxed apps cannot call xattr -d com.apple.quarantine or use removexattr() The entitlement com.apple.security.files.user-selected.read-write doesn't grant xattr removal rights User workaround: run xattr -cr /path/to/plugins in Terminal - not acceptable for professional users Question:
Is there any MAS-compliant way to move files without triggering quarantine, or to remove the quarantine attribute within the sandbox? The hardened-runtime DMG build works perfectly (no sandbox = no quarantine added). Any insight appreciated!

Hello, I am new application developer that has been developing several applications in the productivity and finance sections concurrently for about 1 year. One of my applications is nearly ready to be submitted to the App Store. I have received a lot of discouragement from people who have submitted apps in regards to putting submitting as a paid app, however due to all of the upfront and ongoing investment I've made, I do not wish to release my application for free initially. (I am learning how to best integrate storekit and in-app purchases and subscriptions, but I'm not ready to implement that yet) QUESTION: When releasing an app as a paid app and then converting to a FREE app with subscription later on, is there anything I need to be aware of technically or in regards to guidelines so I don't shoot myself in the foot when changing pricing? Any advice is greatly appreciated. Thank you.

Is there a setting in Settings for None, Ask, or Always for Declared Age? I cannot find anything in iOS 26.2 Settings app, nothing comes up in a search for "age" in Settings. I managed to setup a sandbox apple account (after creating a new email address) and I was able to go to Settings->Developer, login to the sandbox account, and try the various settings for age there, so that much is working. When I call AgeRangeService.shared.requestAgeRange(ageGates: 18, in: presenter) I get "The operation couldn’t be completed. (DeclaredAgeRange.AgeRangeService.Error error 0.)" Is there a way to test this with my regular personal apple unpaid developer account, my work apple developer account with MS SSO, or with the sandbox user? Should I be using requestAgeRange or isEligibleForAgeFeatures? We just have a regular app on the store, it doesn't have chat or anything like that, it's used by licensed truck drivers mostly CDL holders who are 99.99% 18+ in age, possibly some exceptions for 16+ farm drivers. And we would like to stay compliant. Other caveats are that only iOS 26.2 and up are supported, and a judge has blocked the Texas law. Is Apple still supporting the Declared Age Framework or has there been a change?

Hello, I have noticed a performance drop on SpriteKit-based projects running on iOS 26.0 (23A341). Below is a SpriteKit scene used to test framerate on different devices: import SpriteKit import SwiftUI class BareboneScene: SKScene { override func didMove(to view: SKView) { size = view.bounds.size anchorPoint = CGPoint(x: 0.5, y: 0.5) backgroundColor = .darkGray let roundedSquare = SKShapeNode(rectOf: CGSize(width: 150, height: 75), cornerRadius: 12) roundedSquare.fillColor = .systemRed roundedSquare.strokeColor = .black roundedSquare.lineWidth = 3 addChild(roundedSquare) let action = SKAction.rotate(byAngle: .pi, duration: 1) roundedSquare.run(.repeatForever(action)) } } struct BareboneSceneView: View { var body: some View { SpriteView( scene: BareboneScene(), debugOptions: [.showsFPS] ) .ignoresSafeArea() } } #Preview { BareboneSceneView() } The scene is very simple, yet framerate drops to ~40 fps as shown by the Metal HUD. Tested on: iPhone 13, iOS 26.0: framerate drops to 40 fps. Sometimes it runs at near 60fps. But if the screen is touched repeatedly, the framerate drops to 40-50 fps again. iPhone 11 Pro, iOS 26.0: ~40fps. iPad 9th Gen, iOS 18.6.2: 60fps, no issues. See screenshots attached. These numbers were observed by me and members of our beloved SpriteKit Discord server. Thank you for your attention.

Hey there, We've been using App Store Connect API to manage (create/update) Advanced App Clip Experiences via App Store Connect API. Everything has worked fine, we've been able to successfully manage hundreds of app clips but all of a sudden starting on December 15th the API started returning the following error: "id" => "1e15b36b-5347-4af0-9bab-7f6626ffec65" "status" => "409" "code" => "ENTITY_ERROR.INCLUDED.INVALID_ID" "title" => "The provided entity id is invalid" "detail" => "The provided included entity id 'EN' has invalid format" "source" => array:1 [▼ "pointer" => "/included/0/id" ] It does seem to be an API bug considering it has always worked fine and we didn't change anything on our side, the /included/0/id value has always been EN and never changed. Moreover, EN still seems to be a valid value according to the API docs and there are no changes reported of that field in the API release notes. Here's the request ID: 1e15b36b-5347-4af0-9bab-7f6626ffec65 I've tried using different values through trial and error (en, EN, EN-US, ...) and none of them worked.

We've often observed connectivity issues from our VPN app that can only be remedied by removing the VPN profile. It happens to a small but significant amount of our users, this often happens more when the app is updated, but the VPN profile corruption can happen without that too. The behavior we're observing is that any socket opened by the packet tunnel process just fails to send any data whatsoever. Stopping and restarting the packet tunnel does not help. The only solution is to remove the profile and create a new one. We believe our app is not the only one suffering from this issue as other VPN apps have added a specific button to refresh their VPN profile, which seemingly deletes and re-created the VPN configuration profile. Previously, we've caught glimpses of this in a sysdiagnose, but that was a while ago and we found nothing of interest. Alas, the sysdiagnose was not captured on a device with the network extension diagnostic profile (it was not a developer device). I would love to get technical support with this, as our bug reports have gone unanswered for long enough, yet we are still struggling with this issue. But of course, there is no minimum viable xcodeproject that reproduces this. Is there anything we can feasibly do to help with this issue? Is it even an acknowledged issue?

I know this post isn't going to give a lot of details, but what I experienced tonight was so completely weird that I wanted to get it posted here in case others run into it: FIRST: All was well until I made a trivial change to a large Objective-C++ module. I suddenly got the idea to look at that line in the code review pane, to see if that area of code had ever had recent modifications. But, the entire module showed up as modified -- one giant change bar, with nothing on the right side of the code review pane, no matter what commit I selected. Then I noticed that the two lines of code which had all of 4 characters edited were no longer showing any change bars. Yet, the file showed up as "modified". Still, the exact line changes were not showing in the source code navigator, even though other files showed their changes. Note I'm connected to our remote repo on github. I did some command line git checks of the local repo, and the changes were there (as yet unstaged). So -- I figured, I'm gonna ask the Apple Coding Assistant what's up. And it gave some fantastic advice, especially on how to confirm the changes really were in the repo ready to stage and commit and push. Which I did. But despite following a couple hours of wonderful suggestions, I could never get the change bars back -- for this one specific file! (yes, the file was in the repo, and in the project -- everything seemed OK with the file itself -- nothing had changed in the project, which compiled and ran perfectly with my changes). SECOND -- suddenly, the AI assistant seemed to crash Xcode. When I went to re-run Xcode, it just crashed exactly the same. The crash log indicated "Xcode is crashing inside the IDEIntelligenceChat plugin while it’s trying to “apply changes” to a Source Editor buffer". Ultimately, I needed to restart Xcode holding down the SHIFT key. I could open other projects, but not the one I had been working on. So I turned OFF apple Intelligence (thanks, ChatGPT). That allowed me to launch. It sounds like some sort of corrupt Apple Intelligence chat logs and/or caches, which ChatGPT has given me extensive suggestions for deleting. I don't have the energy to attack that tonight -- I did an additional Time Machine backup and hope to take a closer look tomorrow. Ideally -- I'd rather NOT lose all my on-going coding assistant chats for this project -- I had some ongoing suggestions I was working on. But more concerning is the weirdness with changebars affecting this one 7,000 line .mm file. It doesn't seem like there's anything that should affect those change bars for ONE FILE that is in the repo and where changes can be seen from a git diff command line operation. If it's a bug -- I can live with it. But it's worrisome. Other than that, Xcode 26.2 has been running great! Unlike 26.1, which insisted on re-compiling all 600 files in my project every time I ran/debugged, 26.2 just does the 2-6 modified files -- a perfect incremental compile. I've saved HOURS of wasted unnecessary compilation since 26.2 was released.

Hi everyone 👋 I’m fairly new to iOS development and I’ve been stuck on a SwiftUI issue for a while now, so I’m hoping someone here can spot what I’m doing wrong. I’m using navigationTransition(.zoom) together with matchedTransitionSource to animate navigation between views. The UI consists of a grid of items (currently a LazyVGrid, though the issue seems unrelated to laziness). Tapping an item zooms it into its detail view, which is structurally the same view type and can contain further items. All good expect that interactive swipe-back sometimes causes the item to disappear from the grid once the parent view is revealed. This only happens when dismissing via the drag gesture; it does not occur when using the back button. I’ve attached a short demo showing the issue and the Swift file containing the relevant view code. Is there something obvious I’m doing wrong with navigationTransition / matchedTransitionSource, or is this a known limitation or bug with interactive swipe-back? Thanks in advance. import SwiftUI struct TestFileView: View { @Namespace private var ns: Namespace.ID let nodeName: String let children: [String] let pathPrefix: String private func transitionID(for childName: String) -> String { "Zoom-\(pathPrefix)->\(childName)" } private let columns = Array(repeating: GridItem(.flexible(), spacing: 12), count: 3) var body: some View { ScrollView { VStack(alignment: .leading, spacing: 12) { Text(nodeName) .font(.title.bold()) .padding(.bottom, 6) LazyVGrid(columns: columns, spacing: 12) { ForEach(children, id: \.self) { childName in let id = transitionID(for: childName) NavigationLink { TestFileView( nodeName: childName, children: childrenFor(childName), pathPrefix: "\(pathPrefix)/\(childName)" ) .navigationTransition(.zoom(sourceID: id, in: ns)) } label: { TestFileCard(title: childName) .matchedTransitionSource(id: id, in: ns) } .buttonStyle(.plain) } } } .padding() } } private func childrenFor(_ name: String) -> [String] { switch name { case "Lorem": return ["Ipsum", "Dolor", "Sit"] case "Ipsum": return ["Amet", "Consectetur"] case "Dolor": return ["Adipiscing", "Elit", "Sed"] case "Sit": return ["Do", "Eiusmod"] case "Amet": return ["Tempor", "Incididunt", "Labore"] case "Adipiscing": return ["Magna", "Aliqua"] case "Elit": return ["Ut", "Enim", "Minim"] case "Tempor": return ["Veniam", "Quis"] case "Magna": return ["Nostrud", "Exercitation"] default: return [] } } } struct TestFileCard: View { let title: String var body: some View { VStack(alignment: .leading, spacing: 8) { Image(systemName: "square.stack.3d.up") .symbolRenderingMode(.hierarchical) .font(.headline) Text(title) .font(.subheadline.weight(.semibold)) .lineLimit(2) .minimumScaleFactor(0.85) Spacer(minLength: 0) } .padding(12) .frame(maxWidth: .infinity, minHeight: 90, alignment: .topLeading) .background(.thinMaterial, in: RoundedRectangle(cornerRadius: 14, style: .continuous)) } } private struct TestRoot: View { var body: some View { NavigationStack { TestFileView( nodeName: "Lorem", children: ["Ipsum", "Dolor", "Sit"], pathPrefix: "Lorem" ) } } } #Preview { TestRoot() }

Approx Dec 13th 2025 til now (Dec 29th) I noticed my APNS dropped off to nothing daily. When I try to send APNS alerts on the developer site tool it always returns "discarded as device was offline" for multiple devices which I know are online. When I try pushing through my VPS (as I always have without any code changes for months) I get status codes of 400 and 403 mostly and a few 200's without it delivering also. I created a new sandbox certificate just in case it was that but still no luck, I get the same results. Ive checked for any firewall issues and I see the following on my VPS: nslookup gateway.push.apple.com Server: 1.1.1.1 Address: 1.1.1.1#53 ** server can't find gateway.push.apple.com: NXDOMAIN This seems like a second issue but not the primary issue that the portal is reporting. Any ideas what to check? Im at a loss as to why its not working at all through apples test notification portal on my developer account. It seems thats the initial issue I need to solve. Thank you for any ideas/help

I am building a macOS utility using SwiftUI and Swift that records and displays keyboard shortcuts (like Cmd+C, Cmd+V) in the UI. To achieve this, I am using NSEvent.addGlobalMonitorForEvents(matching: [.keyDown]). I am aware that global monitoring usually requires the app to be non-sandboxed. However, I am seeing some behavior I don't quite understand during development: I started with a fresh SwiftUI project and disabled the App Sandbox. I requested Accessibility permissions using AXIsProcessTrustedWithOptions, manually enabled it in System Settings, and the global monitor worked perfectly. I then re-enabled the App Sandbox in "Signing & Capabilities." To my surprise, the app still records global events from other applications, even though the Sandbox is now active. Is this expected behavior? Does macOS "remember" the trust because the Bundle ID was previously authorized while non-sandboxed, or is there a specific reason a Sandboxed app can still use addGlobalMonitor if the user has manually granted Accessibility access? My app's core feature is displaying these shortcuts for the user's own reference (productivity tracking). If the user is the one explicitly granting permission via the Accessibility privacy pane, will Apple still reject the app for using global event monitors within a Sandboxed environment? Code snippet of my monitor: // This is still firing even after re-enabling Sandbox eventMonitor = NSEvent.addGlobalMonitorForEvents(matching: [.keyDown]) { event in print("Captured: \(event.charactersIgnoringModifiers ?? "")") } I've tried cleaning the build folder and restarting the app, removing the app from accessibility permission, but the events keep coming through. I want to make sure I'm not relying on a "development glitch" before I commit to the App Store path. Here is the full code anyone can use to try this :- import SwiftUI import Cocoa import Combine struct ShortcutEvent: Identifiable { let id = UUID() let displayString: String let timestamp: Date } class KeyboardManager: ObservableObject { @Published var isCapturing = false @Published var capturedShortcuts: [ShortcutEvent] = [] private var eventMonitor: Any? // 1. Check & Request Permissions func checkAccessibilityPermissions() -> Bool { let options: NSDictionary = [kAXTrustedCheckOptionPrompt.takeUnretainedValue() as String: true] let accessEnabled = AXIsProcessTrustedWithOptions(options) return accessEnabled } // 2. Start Capture func startCapture() { guard checkAccessibilityPermissions() else { print("Permission denied") return } isCapturing = true let mask: NSEvent.EventTypeMask = [.keyDown, .keyUp] eventMonitor = NSEvent.addGlobalMonitorForEvents(matching: mask) { [weak self] event in self?.processEvent(event) } } // 3. Stop Capture func stopCapture() { if let monitor = eventMonitor { NSEvent.removeMonitor(monitor) eventMonitor = nil } isCapturing = false } private func processEvent(_ event: NSEvent) { // Only log keyDown to avoid double-counting the UI display guard event.type == .keyDown else { return } var modifiers: [String] = [] var symbols: [String] = [] // Map symbols for the UI if event.modifierFlags.contains(.command) { modifiers.append("command") symbols.append("⌘") } if event.modifierFlags.contains(.shift) { modifiers.append("shift") symbols.append("⇧") } if event.modifierFlags.contains(.option) { modifiers.append("option") symbols.append("⌥") } if event.modifierFlags.contains(.control) { modifiers.append("control") symbols.append("⌃") } let key = event.charactersIgnoringModifiers?.uppercased() ?? "" // Only display if a modifier is active (to capture "shortcuts" vs regular typing) if !symbols.isEmpty && !key.isEmpty { let shortcutString = "\(symbols.joined(separator: " ")) + \(key)" DispatchQueue.main.async { // Insert at the top so the newest shortcut is visible self.capturedShortcuts.insert(ShortcutEvent(displayString: shortcutString, timestamp: Date()), at: 0) } } } } PS :- I just did another test by creating a fresh new project with the default App Sandbox enabled, and tried and there also it worked!! Can I consider this a go to for MacOs app store than?

I'm getting reports that my application is creating hidden files with names starting with .f and having 9 or 10 numbers after that. For example: .f678501541 .f1858565508 AFAIK I don't create any files with names like that! So how to determine a) if I am creating those files and b) exactly where in my code this is happening? Unless of course someone knows what creates files like this... Thanks, David

We're building a parental control app using FamilyControls (.child authorization). Our architecture: Parent sends pause command → Firestore + FCM Child receives push → NotificationService Extension triggers main app Main app sets ManagedSettings Shields Problem: If child disables Notifications in Settings and force-quits the app, we cannot enforce Shields. What we've tried: Firestore Realtime Listener (works only when app is running) DeviceActivityMonitor (intervalDidStart/End only triggers at schedule boundaries, eventDidReachThreshold requires explicit app selection via FamilyActivityPicker) Question: Is there a recommended approach for parental control apps to reliably enforce Shields when the child has disabled notifications? Or is this a known limitation?

Hello, Im not sure why this happens.This is frustrating to see that despite paying the heavy amounts to join developer programme.The account is not getting confirmed surpassing way more than 48 hours of the payment. I paid the amount on 26th of December. and today is 29th. will you be compensating on the days we lost in this review process ?

各位大神有没有人知道苹果手机玩法隐藏技巧？

Hello, I am trying to find out the best way to move my app from Base 44 to the App Store. I know its a process but I want to do it the best way possible to avoid any issues with the migration.

I am porting my app to SwiftUI and I am hitting a wall when using ScrollView. In my application, I have nested scrollViews to represent a scheduler. outer vertical scroll view inner horizontal scroll view that allows to horizontally scroll multiple columns in the scheduler each column in the inner scroll view is a view that needs to allow for a drag to initiate the creation of a new appointment on macOS, I do a mouse-down drag, so it does not affect the scroll view and works fine on iOS, if I add a drag gesture to the column, it short circuits the scroll view and scrolling becomes disabled. To initiate the drag, there is a long-press, and that gesture is fine, only the subsequent drag gesture is problematic. I have attached URL to a test app. The UI allows you to toggle the drag gesture. Hopefully, someone can help to get it to work since I would eventually like to port the macOS target to Catalyst.

Hello All, I've been finally able to finish my so called Quantumsort implementation, which is basically only slightly modified Radix Sort at the basis, but utilizes the somewhat newish Apple Metal SIMD commands heavily. Or rather rather renders the threadgroup shared memory void altogether with those SIMD sharing options available. The sorting itself works "well enough" for my needs here on these Github shared main.swift and sort.metal files already, and the question relates more on it that - can someone spot would it be possible to get rid of the "sorted_temp" array memory too and use one "sorted" list only at all times..? Here's the related repository and copilots I prefer you and you and you more for haha tho : https://guthib.com/roger-more-fi/quantumsort Cheers, make it to the perfection those good last ones of '25 'aights Apple soldiers!

As the title says, I am enrolled in the small business program but Apple still takes about 30% of my sales. Most of my sales are from Swedish customers, not sure if this matters. For instance I have an app with sales of: $109 After apples cut I am left with: $74 74/109 = 0.68. Why is this? I have non consumable IAP in my app.
