Overview

I’m updating a legacy application that used Apple Pay v1 token format, and in my new revamped version I’m now receiving the newer Apple Pay v2 format. The old (v1) payload looked like this: php { "version": "EC_v1", "data": "...", "signature": "...", "header": { "ephemeralPublicKey": "...", "publicKeyHash": "...", "transactionId": "..." } } In the new revamp (v2), Apple Pay returns this instead: php { "signedTransactionInfo": "eyJhbGciOiJFUzI1NiIsIng1YyI6WyJNSUlF..." } From what I understand: v1 tokens were elliptic-curve encrypted JSON objects containing a header and signature. v2 tokens seem to be JWS (JSON Web Signature) strings using the ES256 algorithm, possibly containing transaction and subscription details inside. Questions Is there any official Apple documentation or migration note explaining the move from EC_v1 → signedTransactionInfo? How should I verify or decode the new signedTransactionInfo payload? Should the verification now use Apple’s public keys instead of the legacy Merchant ID certificate? Are there any example implementations or SDKs that can handle both v1 and v2 formats during migration? Is there a recommended way to maintain backward compatibility while transitioning existing users? Goal Ensure that my revamped app can handle Apple Pay v2 tokens securely while keeping the legacy v1 integration functional until all users are migrated.

Hi everyone, I’m trying to reproduce the layout Apple Music uses for playlists, where there is header content above the table (artwork, title, buttons), and when you scroll, everything scrolls together—the header and table rows move as a single scrollable region. Here’s an example of what I’m trying to achieve: I’m using SwiftUI’s Table view and I haven’t found a clean way to place custom content above the table while keeping everything inside the same scroll view. Is there currently a recommended way to achieve Apple Music–style scrollable header + table content using SwiftUI? Thanks!

A functioning Multiplatform app, which includes use of Continuity Camera on an M1MacMini running Sequoia 15.5, works correctly capturing photos with AVCapturePhoto. However, that app (and a test app just for Continuity Camera) crashes at delegate callback when run on a 2017 MacBookPro under MacOS 13.7.5. The app was created with Xcode 16 (various releases) and using Swift 6 (but tried with 5). Compiling and running the test app with Xcode 15.2 on the 13.7.5 machine also crashes at delegate callback. The iPhone 15 Continuity Camera gets detected and set up correctly, and preview video works correctly. It's when the CapturePhoto code is run that the crash occurs. The relevant capture code is: func capturePhoto() { let captureSettings = AVCapturePhotoSettings() captureSettings.flashMode = .auto photoOutput.maxPhotoQualityPrioritization = .quality photoOutput.capturePhoto(with: captureSettings, delegate: PhotoDelegate.shared) print("**** CameraManager: capturePhoto") } and the delegate callbacks are: class PhotoDelegate: NSObject, AVCapturePhotoCaptureDelegate { nonisolated(unsafe) static let shared = PhotoDelegate() // MARK: - Delegate callbacks func photoOutput( _ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)? ) { print("**** CameraManager: didFinishProcessingPhoto") guard let pData = photo.fileDataRepresentation() else { print("**** photoOutput is empty") return } print("**** photoOutput data is \(pData.count) bytes") } func photoOutput( _ output: AVCapturePhotoOutput, willBeginCaptureFor resolvedSettings: AVCaptureResolvedPhotoSettings ) { print("**** CameraManager: willBeginCaptureFor") } func photoOutput(_ output: AVCapturePhotoOutput, willCapturePhotoFor resolvedSettings: AVCaptureResolvedPhotoSettings) { print("**** CameraManager: willCaptureCapturePhotoFor") } } The crash report significant parts are.....

Since updating to Tahoe and Xcode 26 I have found that the UISplitViewController.showDetailViewController() is not working in the iPhone version of my app (it is a universal app). I'm just trying to show a detail view after a tap on a UITableView item. The iPad versions are all working correctly. Has anyone else experienced this or have any advice about what may have changed? Thanks in advance.

I am running some experiments with WebGPU using the wgpu crate in rust. I have some Buffers already allocated in the GPU. Is it possible to use those already existing buffers directly as inputs to a predict call in CoreML? I want to prevent gpu to cpu download time as much as possible. Or are there any other ways to do something like this. Is this only possible using the latest Tensor object which came out with Metal 4 ?

i'm trying to understand which entitlements i need to ask for in order to be able to read the credit card via NFC. I work for the bank and i'd like the read our card in order to verify there are the bank's credit card. The goal is to be able to use the card as a physical token to verify the user identity. on android we manage to do this without limitation if (await NfcManager.isSupported()) { await NfcManager.requestTechnology(NfcTech.IsoDep) const tag = await NfcManager.getTag() if (tag) toast.success("NFC Tag read successfully", { cancel: undefined, description: tag.id, id }) else toast.error("No NFC Tag found", { cancel: undefined, id }) const ppse = await NfcManager.isoDepHandler.transceive([ 0x00, 0xa4, 0x04, 0x00, 0x0e, 0x32, 0x50, 0x41, 0x59, 0x2e, 0x53, 0x59, 0x53, 0x2e, 0x44, 0x44, 0x46, 0x30, 0x31, 0x00, ]) logger.info("PPSE", ppse.map((c) => fromBase10ToHex(c, 2)).join(" ")) const select = await NfcManager.isoDepHandler.transceive([ 0x00, 0xa4, 0x04, 0x00, 0x07, 0xa0, 0x00, 0x00, 0x00, 0x04, 0x10, 0x10, 0x00, ]) logger.info("Select AID", select.map((c) => fromBase10ToHex(c, 2)).join(" ")) const gpo = await NfcManager.isoDepHandler.transceive([0x80, 0xa8, 0x00, 0x00, 0x02, 0x83, 0x00, 0x00]) logger.info("GPO", gpo.map((c) => fromBase10ToHex(c, 2)).join(" ")) const record = await NfcManager.isoDepHandler.transceive([0x00, 0xb2, 0x01, 0x14, 0x00]) logger.info("record: ", record.map((c) => fromBase10ToHex(c, 2)).join(" ")) logger.info("PAN", findTag(record, [0x5a])) logger.info("expiry", findTag(record, [0x5f, 0x24])?.reverse()) } but on ios we have restricted access and the ppse doesn't work but i can't find which entitlement i need to ask for, since HCE is to make the iphone into a nfc tag himself and the tap to pay is to pay with the iphone, both of those doesn't match my needs and i wouldn't be able to valid the requirement to get them into production. So i am wondering which entitlement i needs to ask for in order to be able to scan the card inside the bank app. We only care about our card

Hello, I’m seeking help regarding an App Review situation that has become increasingly difficult to resolve. Our app has been in review since July 29, and despite multiple rounds of communication, detailed explanations, updated builds, and full implementation of all required changes, the review process continues to stall without clear feedback. Most recently, we received new review questions regarding the External Purchase entitlement and the “Notify Me When Open” feature. We provided a detailed explanation addressing each point, including clarification that: All digital purchases, including Online Groups, use the StoreKit External Purchase API. The External Purchase Modal Sheet appears before every purchase flow. The “Notify Me When Open” feature does not initiate or bypass a payment flow; it only notifies users when a time-scheduled course becomes available, after which the user proceeds through the standard StoreKit External Purchase Modal Sheet. After submitting these explanations, our app returned to the “In Review” state. However, it has now remained there for five consecutive days, again with no further questions or updates. When combined with the previous review cycles, the total delay is approaching five months. This extended review period is causing significant challenges for our service, as users have been unable to access essential updates and continue facing issues in the outdated version of the app. Has anyone experienced a similar situation where the review remains stuck even after addressing all feedback and providing the required materials? Is there any additional way to escalate or request deeper assistance beyond the standard channels? Any guidance or shared experience would be greatly appreciated. Thank you.

Issue Summary: iOS 26 UI components are not visible in the Expo app when installed via TestFlight. All components render correctly in local builds or when running with expo run:ios. Details: The app is built using Expo managed workflow. iOS 26-specific UI components do not appear in TestFlight builds. The same components display correctly in local builds and simulators. Test device: iPhone running iOS 26.1. There are no crashes or runtime errors; only the components are missing. This issue occurs only in TestFlight/release builds. Expected Behavior: All iOS 26 UI components should render in TestFlight builds the same way they do in local builds. Actual Behavior: Components fail to render or are completely missing. Device Information: Device: iPhone iOS Version: 26.1 Distribution: TestFlight Local Build: Working correctly Additional Notes: This may be related to Expo release build optimization or iOS 26 SDK compatibility.

When an iOS device is connected to a Bluetooth accessory that utilizes the Hands-Free Profile (HFP), we are encountering an incorrect audio routing behavior specifically for system notification tones. Accessory Connected: The iOS device is successfully connected to a Bluetooth accessory (specifically, a WM500 device) using the HFP profile for voice communication. Voice Audio: Audio streams related to phone calls or voice communication (using the HFP/SCO link) are correctly routed to the WM500. Notification Tones Issue: System notification tones, which are played using the tonetype.systemsounds API, are not being routed to the connected HFP accessory (WM500). Instead, they are incorrectly played through the iOS device's built-in speaker. This causes a poor user experience, as critical application alerts and system notifications are missed when the user is relying on the connected HFP accessory for all audio output.

We are currently implementing a custom iCloud sync for our macOS and iOS apps using CloudKit. Syncing works fine as long as the number of record sends is relatively small. But when we test with a large number of changes ( 80,000+ CKRecords ) we start running into problems. Our sending strategy is very conservative to avoid rate limits: We send records sequentially in batches of 250 records With about 2 seconds pause between operations Records are small and contain no assets (assets are uploaded separately) At some point we start receiving: “Database commit size exceeds limit” After that, CloudKit begins returning rate-limit errors with retryAfter-Information in the error. We wait for the retry time and try again, but from this moment on, nothing progresses anymore. Every subsequent attempt fails. We could not find anything in the official documentation regarding such a “commit size” limit or what triggers this failure state. So my questions are: Are there undocumented limits on the total number of records that can exist in an iCloud database (private or shared)? Is there a maximum volume of record modifications a container can accept within a certain timeframe, even if operations are split into small batches with pauses? Is it possible that sending large numbers of records in a row can temporarily or permanently “stall” a CloudKit container? Any insights or experiences would be greatly appreciated. Thank you!

Currently Xcode has iOS simulators that allow easily testing apps on older versions of iOS. It would be helpful if there was also a macOS simulator for testing apps on older versions of macOS. FB21229682 https://github.com/feedback-assistant/reports/issues/724

I am trying to implement a common UX/UI pattern: one view with rounded corners transitioning to a view that fills the screen (N.B. having the display's corner radius). I got this to work if both corner radiuses are equal to that of the display (see first GIF). However, I cannot seem to get it to work for arbitrary corner radiuses of the smaller view (i.e., the one that does not fill the screen). I expected the be able to combine ContainerRelativeShape with .containerShape (see code), but this left me with a broken transition animation (see second GIF). import SwiftUI struct ContentView: View { @Namespace private var animation @State private var selectedIndex: Int? var body: some View { ZStack { if let selectedIndex = selectedIndex { ContainerRelativeShape() .fill(Color(uiColor: .systemGray3)) .matchedGeometryEffect(id: "square-\(selectedIndex)", in: animation) .ignoresSafeArea() .onTapGesture { withAnimation() { self.selectedIndex = nil } } .zIndex(1) } ScrollView { VStack(spacing: 16) { ForEach(0..<20, id: \.self) { index in if selectedIndex != index { ContainerRelativeShape() // But what if I want some other corner radius to start with? .fill(Color(uiColor: .systemGray5)) .matchedGeometryEffect(id: "square-\(index)", in: animation) .aspectRatio(1, contentMode: .fit) .padding(.horizontal, 12) .onTapGesture { withAnimation() { selectedIndex = index } } // .containerShape(RoundedRectangle(cornerRadius: 20)) // I can add this to change the corner radius, but this breaks the transition of the corners } else { Color.clear .aspectRatio(1, contentMode: .fit) .padding(.horizontal, 12) } } } .padding(.vertical, 16) } } } } #Preview { ContentView() } What am I missing here? How can I get this to work? And where is the mistake in my reasoning?

I'm looking for a way to make the following possible in Xcode (26.0 or later): I select one or more lines of code. I then enter a hotkey (or select a menu item) that results in adding the line: #ifdef SOME_MACRO before the selection and adding the line: #endif after the selection. Example: Start with the following lines of code: BOOL x = NO; int y = 4; NSString *str = @"Hello"; If I then highlight the int y = 4; line and use the proper hotkey or menu, the result would be: BOOL x = NO; #ifdef SOME_MACRO int y = 4; #endif NSString *str = @"Hello"; Is something like this possible in Xcode? I looked at code snippets but that doesn't seem to support wrapping existing code. I looked at the Xcode Settings under Editor and Shortcuts and didn't see a way to add such a custom shortcut.

When I try to validate my app I get the following error: Invalid bundle. Because your app supports Multitasking on iPad, you need to include the LaunchScreen.storyboard launch storyboard file in your com.augmentedReality.virtualTags bundle. Use UlLaunchScreen instead if the app's MinimumOSVersion is 14 or higher and you prefer to configure the launch screen without storyboards. For details, see: https:// developer.apple.com/documentation/bundleresources/information_property_list/ uilaunchstoryboardname (ID: 236f630a-a014-48e8-910a-77d9c0ff6f51) What should I do to fix it? In the previous Xcode version and on another app it did not appear. MacBook Pro M5, Tahow 26.1, Xcode 26.1.1

​ My app has been rejected multiple times during the last few weeks because Apple reviewer is unable to complete the purchase on revenue cat paywall. They gave this error message: Guideline 2.1 - Performance - App Completeness We were still unable to purchase the subscription successfully. Review device details: Device type: iPad Air 11-inch (M2) OS version: iPadOS 26.1 Next Steps When validating receipts on your server, your server needs to be able to handle a production-signed app getting its receipts from Apple’s test environment. The recommended approach is for your production server to always validate receipts against the production App Store first. If validation fails with the error code "Sandbox receipt used in production," you should validate against the test environment instead.

I think issue might be because my subscriptions on App Store are not approved but I’m not sure. I heard you are supposed to submit them same time when you submit your build. I submitted both but Apple also rejected my subscriptions saying the images were duplicate.

Hello, I requested Fairplay credentials a week ago. Where can I check the status of my request? Thank you very much. The team ID is: 6WZ8SVRYV9

Hi, I'm stuck in a loop with my app submission: Created auto-renewable subscriptions in App Store Connect Status: "Waiting for Verification" App gets rejected: "in-app purchases don't display" But they can't display because they're not approved yet Question: Do I need to attach the subscriptions to my app version BEFORE submitting? If so, where? I've done: Created subscription group with metadata Configured pricing and localizations Set up RevenueCat integration What am I missing to get out of "Waiting for Verification"? Thanks!
