Overview

Hi, To ensure the issue is not caused by an error within your app or web service request, please review the Apple Pay Merchant Integration Guide. Additionally, please review the following technotes on Apple Pay: TN3173: Troubleshooting issues with your Apple Pay merchant identifier configuration TN3174: Diagnosing issues with the Apple Pay payment sheet on your website TN3175: Diagnosing issues with displaying the Apple Pay button on your website TN3176: Troubleshooting Apple Pay payment processing issues TN3206: Updating Apple Pay certificates If the resources above don’t help identify the cause of the error, please provide more information about your app or web services to get started. To prevent sending sensitive credentials in plain text, create a report in Feedback Assistant to share the details requested below. Additionally, if the error is something we need to investigate further, the appropriate engineering teams also have access to the same information and can communicate with you directly within Feedback Assistant for more information, as needed. Please follow the instructions below to submit your report. For issues occurring with your native app or web service, perform the following steps: Install the Apple Pay profile on your iOS or watchOS device. If the issue occurs on Mac, continue to Step 2. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS or watchOS device, or on macOS. Create a Feedback Assistant report with the following information: The serial number of the device. For iOS and watchOS: Open Settings > General > About > Serial Number (tap and hold to copy). For macOS: Open the Apple () menu > About This Mac > Serial Number. The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string. For iOS and watchOS: open Settings > General > About > SEID (tap and hold to copy). For macOS: Open the Apple () menu > About This Mac > System Report > NVMExpress > Serial Number. The sysdiagnose gathered after reproducing the issue. The timestamp of when the issue was reproduced. Screenshots or videos of errors and unexpected behaviors (optional). Important: From the logs gathered above, you should be able to determine the cause of the failure from PassbookUIService, PassKit or PassKitCore, and by filtering for your SEID or merchant domain in the Safari Web Inspector. See Inspecting Safari on macOS to learn more. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Apple Pay website. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your web implementation, a configuration issue within your developer account, or an underlying system bug.

We're developing a service that requires webtransport support in the browser. Currently, the only browser that doesn't provide support is the IOS version of Safari. Our current way forward for client use is to flag iphone and ipad as non compliant and recommend either desktop use or android. Is there any ballpark date as to when WebTransport will be included in IOS Safari (- webkit supports webtransport)?

Hello, I am using the prf extension for passkeys that is available since ios 18 and macos15. I am using a fixed, hardcoded prf input when creating or geting the credentials. After creating a passkey, i try to get the credentials and retrieve the prf output, which works great, but i am getting different prf outputs for the same credential and same prf input used in the following scenarios: Logging in directly (platform authenticator) on my macbook/iphone/ipad i get "prf output X" consistently for the 3 devices When i use my iphone/ipad to scan the qr code on my macbook (cross-platform authenticator) i get "prf output Y" consistently with both my ipad and iphone. Is this intended? Is there a way to get deterministic prf output for both platform and cross-platform auth attachements while using the same credential and prf input?

Same scenario described here: https://forums.developer.apple.com/forums/thread/738942 User clicked accept for an internal tester invitation sent to their work apple id on their personal device which was signed in with their personal apple id. This seems to have redeemed the code to the users personal account. However, the user has removed themselves from testing the app and we're trying to get their work apple id registered but the invite code that keeps being sent is coming back saying invalid. Things we've tried: We located the last build the user installed on their device and expired the builds deleted / readded the work apple id to internal testing group It's still sending the same invitation code from TestFlight and saying that the code cannot be redeemed.

Hello. My developer membership is expired. I cannot renew because the renewal option/button does not appears in any device. A banner tells me: "Any apps you had on the App Store are no longer available for download and you can no longer access membership benefits. If you’d like to renew your membership to reinstate your apps and membership benefits, open the Apple Developer app on your iPhone, iPad, or Mac. Sign in to your account, tap/click Renew, and follow the prompts.If you agreed to the Paid Applications Agreement, you’ll need to agree to it again after renewal in the Agreements, Tax and Banking section of App Store Connect." However, there's no "Renew" to tap or click anywhere in the app nor in the web. Any ideas? Thanks a lot.

Hello, I used AVPlayer in my project to play network movie. Most movie could play normally, but I found the sound will disappear sometimes if I play specified 4K video network stream. The video will continue playing but audio stops after video is played for a while. If I pause player and then resume, the sound will be back but disappeared again after several seconds Check AVPlayerItem status: isPlaybackLikelyToKeepUp` == true isPlaybackBufferEmpty` = false player.volume > 0 According the value above, it seems not cause by empty playback buffer or volume issue. I am so confused for this situation. Movie information Video Format : AVC Format/Info : Advanced Video Codec Format profile : High L5.1 Codec ID : avc1 Codec ID/Info : Advanced Video Coding Bit rate mode : Variable Bit rate : 100.0 Mb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 29.970 (30000/1001) FPS Audio Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : mp4a-40-2 Duration : 5 min 19 s Bit rate mode : Constant Bit rate : 192 kb/s Nominal bit rate : 48.0 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF) Does anyone know if AVPlayer has this limitations when playing high-bitrate movie streams, and are there any solutions?

When an app is trying to access identities put in the keychain by cryptotokenkit extension, the user gets asked a permission pop-up which reads 'Token Access Request" would like access a token provided by: " with 2 options 'Don't allow' and 'OK' I accidently clicked "Don't allow" and now can't access identities put in crypto token kit. How can I reset the preference?

I'm running a macOS 15.2 guest on a macOS 15.1.1 host with UTM. I'm trying to install Xcode from within the App Store but cannot login to the App Store. When I enter credentials and click 'Sign In' I get the Error 'An unknown error occurred'.

NavigationTitle does not change when the app language changes. It works well in iOS 17.5 but does not in iOS 18.x

I'm facing an issue with Swift Playgrounds and files created in Xcode 16. It seems that Swift Playgrounds does not support Swift 6, but even when I create files specifically with Swift 5, Swift Playgrounds still reports that the files are unsupported. This creates a significant problem because macOS Sequoia does not allow me to revert to Xcode 15, which might have offered better compatibility. As it stands, I can't find a solution to work seamlessly between Xcode and Swift Playgrounds. Has anyone else encountered this issue? Are there any workarounds or updates planned to address this compatibility gap? Any advice would be greatly appreciated!

Hello My app got rejected with the message "We noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences." In short, my app is a vpn app built entirely by me. In Russia almost all vpn protocols are blocked: wireguard, openvpn etc. And the only protocol they could not block was vless. It was hard to implement it, i spent like 3 weeks on it writing my own package on flutter. The app first was uploaded to android and shared through testflight with some of my friends. And everyone switched to my app, because it works perfect for their needs: accessing instagram, twitter etc. Those apps are blocked here. So on my first attempt publishing i got 2 errors: Vpn should be published on the account that is organization Spam rejection I registered a company and switched from individual account to a company. I also changed the ui of the app (although i agree most vpns share the same concept design). I got rejected again with only "Guideline 4.3(a) - Design - Spam". I appealed with a question why was it it rejected, explaining that the app was built by me, and of course, i use some libraries. I got the same roboting response. After that i added some features: Built in private browser Network connection speed Today submitted the new version hoping it would pass, but yet again got "Guideline 4.3(a) - Design - Spam". I'm really frustrated, because i spent 3 months developing the app. I understand there are dozens of vpns. But vpn is not exactly the simple feature app. Some are bad, some are good, and some doesn't work at all. My app doesn't have any ads and paid subscriptions. I also renamed my app to "Incognito - Browser, VPN". But can't get pass. Would like to get some advices. Please help P.S. Sorry for my bad grammar

Hello. I have a few questions about the implementation of Apple Pay payments on websites. Could you help me From the documentation: Apple Pay issues an Apple Pay Merchant Token if the user’s payment network supports merchant-specific payment tokens. Otherwise, Apple Pay issues a device token for the payment request. How can we determine whether a token is a merchant token or a device token? Is it possible to determine this by any of the token fields? https://developer.apple.com/documentation/passkit/payment-token-format-reference Is it possible to understand this in other ways? Can I make recurring payments with the device token if it was issued instead of the merchant token? Is it necessary to include the tokenNotificationURL when generating a merchant token, or can we generate one without specifying it? What does the applicationExpirationDate field in the merchant token represent? Is this the date when the device token or merchant token expires and payments cannot be made with it?

I added a Content Filter to my app, and when running it in Xcode (Debug/Release), I get the expected permission prompt: "Would like to filter network content (Allow / Don't Allow)". However, when I install the app via TestFlight, this prompt doesn’t appear at all, and the feature doesn’t work. Is there a special configuration required for TestFlight? Has anyone encountered this issue before? Thanks!

Does anyone know if there will be a Swift 6 version of "The Swift Programming Language" book and if so, when it will be released for Apple Books?

Hi everyone, I've recently implemented CKSyncEngine in my app, and I have two questions regarding its behavior: Duplicate FetchedRecordZoneChanges After Sending Changes: I’ve noticed that the engine sometimes receives a FetchedRecordZoneChanges event containing modifications and deletions that were just sent by the same device a few moments earlier. This event arrives after the SentRecordZoneChanges event, and both events share the same recordChangeTag, which results in double-handling the record. Is this expected behavior? I’d like to confirm if this is how CKSyncEngine works or if I might be overlooking something. Handling Initial Sync with a "Sync Screen": When a user opens the app for the first time and already has data stored in iCloud, I need to display a "Sync Screen" temporarily to prevent showing partial data or triggering abrupt, rapid UI changes. I’ve found that canceling current operations, then awaiting sendChanges() and fetchChanges() works well to ensure data is fully synced before dismissing the sync screen: displaySyncScreen = true await syncEngine.cancelOperations() try await syncEngine.sendChanges() try await syncEngine.fetchChanges() displaySyncScreen = false However, I’m unsure if canceling operations like this could lead to data loss or other issues. Is this a safe approach, or would you recommend a better strategy for handling this initial sync state?

Trying to use IOLog to print out a message from a dext. When I try to use IOLog, I get , though I did not or thought I did not tag it as private. I have tried to update the info.plist file for the dext according to https://developer.apple.com/forums/thread/705810, but that has not helped, or perhaps I am not defining it correctly since it's a dext. Anyone else had this issue, and how did you fix it?
