Hi, I'm posting a boot crash here. Environment Hardware: Macbook M5 Pro OS Version: macOS 26.3.1 (25D2128) and matching version of KDK from official apple download page Kernel Version: Darwin Kernel Version 25.3.0 Reproducibility: Consistent Here is my panic log --- I truncated one field "SOCDNandContainer" as the original log is too long to post, hitting the size limit. I followed a blog post to boot the development kernel as the ReadMe file from KDK only contains instructions for Intel Macs. https://jaitechwriteups.blogspot.com/2025/10/boot-custom-macos-kernel-on-macos-apple.html I've tried a few 26.2 KDKs before 26.3.1 public launch, and they all showed same errors (26.1 and 26.0 KDKs don't have any development kernel for T8142 chip). Also, I own two fresh M5 Pro, and it is consistent across the machines. The highlight is panic(cpu 8 caller 0xfffffe0050e18010): [Exclaves] $JgOSLogServerComponent.RedactedLogServer.init(logServerNotific:OSLogServerComponent\/OSLogServerComponent_Swift.swift:815: Fatal error: invalid rawValue for TightbeamComponents.RedactedLogSer at PC ... Is this a genuine bug or am I following a wrong guide to boot the development kernel? I don't think the blog is wrong because I'm able to boot the "release" kernel included in the KDK on the same M5 Pro, and the "development" kernel on M4 Mac Mini, using the same routine. Just to be clear, I'm not compiling XNU myself, but am using the ones included in the kit.

I currently have a schema in production (cloudKit and local files) containing non-optional transformable values, e.g. @Attribute(.transformable(by: TestTransformer.self)) var number: TestTransformable = TestTransformable.init(value: 100) Unfortunately, this is preventing any migration from succeeding (documented at length in FB22151570). Briefly summarized, any migration from a Schema containing non-optional transformable values fails between willMigrate and didMigrate with the error "Can't find model for source store". This occurs for all migrations, including lightweight with a migration plan, lightweight without a plan, and custom migrations. Worst of all, this also prevents migration to optional transformable values, or the elimination of the transformable value entirely, leaving us completely stuck. (note: optional transformable values only work when they have a default value set to nil, otherwise even these have issues migrating) We already have features being blocked by this issue, and would like to preserve user-data while restoring our ability to move forwards with database. Are there any known workarounds for using SwiftData (+CloudKit) when schema migration is non-operational?

Hey! We discovered an unexpected side-effect of enabling enforceRoutes in our iOS VPN application - video airplay from iOS to tvOS stopped working (Unable to Connect popup appears instead). Our flags combination is: includeAllNetworks = false enforceRoutes = true excludeLocalNetworks = true Interestingly, music content can be AirPlayed with the same conditions. Also, video AirPlay from iOS device to the macOS works flawlessly. Do you know if this is a known issue? Do you have any advice if we can fix this problem on our side, while keeping enforcRoutes flag enabled?

Hi Everyone, We are currently migrating a mature legacy KEXT to DriverKit for our PCIe SCSI storage controller (connected via Thunderbolt 3). During the DEXT load sequence, we have observed that the system automatically triggers a power state transition from State 0 (Off) to State 2 (On). However, this process results in a Kernel Panic due to a timeout after approximately 21 seconds. We have verified that our implementation of Start_Impl, UserInitializeController_Impl, and SetPowerState_Impl executes extremely fast, with a total execution time of less than one second. Specifically, SetPowerState_Impl returns kIOReturnSuccess immediately upon being called. Furthermore, our current Info.plist does not contain any IOPowerManagement dictionary or related keys. Despite the fast execution and the absence of explicit power management declarations in the plist, the kernel power management state machine (IOServicePM) still generates a 21-second timeout, leading to the following panic: Panic Log: panic(cpu 7 caller 0xfffffe0020be8fec): MySCSIDriver::setPowerState(0xfffffe2fb1a65c00 : 0xfffffe0020bfed88, 0 -> 2) timed out after 21257 ms @IOServicePM.cpp:5609 com.example.driver.dext: ( id: com.example.driver.dext; path: /Library/SystemExtensions/[UUID]/com.example.driver.dext; state: loaded ) Note on Previous Discussion: I would like to express my gratitude to Kevin from Apple DTS for the helpful discussion regarding the implementation of BundleParallelTask on the forums. Since then, we have shifted our development focus toward completing the overall management ecosystem, delivering a comprehensive operational interface for users, and handling specific user environments and behaviors. Our current priority is ensuring system stability—specifically resolving these Thunderbolt-related power management issues (sleep/wake)—to prepare the product for upcoming testing. I remain very grateful for the guidance provided on batch task optimization and intend to resume those optimizations once this critical stability baseline is secured. Technical Guidance Needed for PM Migration In our legacy KEXT, we utilized PMinit(), registerPowerDriver(), and joinPMtree() to precisely control the timing of power management registration. In transitioning to the DriverKit SDK, we have not found clear guidance on several key points: Standardized Migration Path: What is the recommended way to implement equivalent power management initialization (formerly PMinit) within a DriverKit subclass? In DriverKit, how should we replicate the behavior of manually calling registerPowerDriver and joinPMtree to ensure the driver is only monitored once the hardware is ready? Implicit Power Registration: Why does the system enforce a setPowerState(0 -> 2) transition on a subclass of IOUserSCSIParallelInterfaceController even when no IOPowerManagement dictionary is defined in the Info.plist? Is this a default behavior of the SCSI or PCI transport framework? Thunderbolt Specifics: Are there specific power proxying requirements or configurations for PCIe devices over Thunderbolt to avoid conflicts with the default IOPCIFamily power policies? Best Regards, Charles

Hi Apple Pay Team, We are building a QR-based payment platform and planning to integrate Apple Pay on the Web as a Payment Platform Integrator. Our setup: We operate a single domain (e.g., pay.example.com) where all Apple Pay transactions take place When a customer scans a merchant's QR code, our hosted page opens with the Apple Pay button We process payments on behalf of multiple merchants (receivers), each with a separate merchant ID at our payment processor We want to use a single Payment Platform Integrator ID with one set of certificates (Merchant Identity + Payment Processing) The payment processor handles sub-merchant identification and settlement to the correct receiver via card network (Visa/Mastercard) sub-merchant fields Our question: Since all transactions happen on our single domain, is it mandatory to register each sub-merchant via the Apple Pay Web Merchant Registration API (/paymentservices/registerMerchant) and use their partnerInternalMerchantIdentifier in the payment session request? Or is it acceptable to use our Platform Integrator's own merchant identifier for all payment sessions, given that: Only one domain is involved Sub-merchant identification is handled at the payment processor / card network level Our domain verification file is already hosted and verified We would appreciate clarity on the correct approach before we proceed with our integration. Thank you.

Hello everyone, I’m an iOS developer working on a real-time communication app that supports VoIP calls using CallKit. The app has been in production for more than 5 years. Over the years, some users have occasionally reported that they do not receive incoming call pushes. We have tried multiple optimizations on both the client and server side, but the improvement has been limited. From Apple documentation and discussions online, I understand that iOS may restrict VoIP pushes if the system detects violations of VoIP push usage rules (for example, not presenting a CallKit call after receiving a VoIP push). However, the exact rules and thresholds for these violations are not clearly documented, so I’d like to ask a few questions to better understand the expected behavior. Below is a simplified description of our current call flow. Call Flow Caller When the user initiates a call: We do not use CallKit The call is handled entirely using a custom in-app call UI Callee When the user receives a call: Device locked or app in background A VoIP push wakes the app The app presents the CallKit incoming call UI App in foreground The server still sends a VoIP push The app first reports the call to CallKit After a very short delay, the app programmatically ends the CallKit call Then a custom in-app call UI is presented via the app's long connection The reason we always send a VoIP push (even when the app is in the foreground) is that we want to maximize call delivery reliability.

I display the BackgroundLocationIndicator (blue/white bubble in status bar) in all my apps, that use background location service. Up to iOS 18 it allowed the user to tap on the bubble from within any other non fullscreen app and bring the app using the background location service to the foreground. In iOS26 this only works from the home screen. Is this intended behaviour or a bug ? If intended, please provide us with an option to allow the user to keep the pre iOS26 behavour. This was a quite convenient shortcut to jump directly to the locationservice using app.

Hello, I am currently testing In-App Purchases for my app in the Sandbox environment. Our app has two types of products: Auto-renewable subscriptions Non-renewing subscriptions When testing auto-renewable subscriptions, I can see the subscription in the Sandbox account management screen, and I can perform actions such as: Viewing the active subscription Cancelling the subscription Upgrading or downgrading the subscription However, when testing non-renewing subscriptions, I cannot find the purchase history anywhere in the Sandbox account management screen. Because of this, I cannot verify whether the non-renewing subscription purchase was recorded correctly. My question is: Where can I check the purchase history for Non-Renewing Subscriptions in the Sandbox environment? Is there a specific place in: App Store Connect Sandbox account settings Or somewhere else where these purchases can be reviewed? Thank you in advance for your help.

The developer payment page is returning a 503 error, preventing me from making the payment. Why is this happening? I need to complete this payment urgently.

Hello, I’m working on an iOS app where we have integrated ActivityKit to support Live Activities. Our app currently supports iOS 16.x and above, and we do not have an Apple Watch app or watchOS support. However, we noticed that when a Live Activity starts on the iPhone, it automatically appears on the Apple Watch as well. Since our app is not designed for Apple Watch, we would like to prevent the Live Activity UI from appearing on the watch. My questions: Is there any way to disable or prevent Live Activities from showing on Apple Watch via code? Are there any configuration options in ActivityKit or Widget configuration that can restrict Live Activities to iPhone only? Our current setup: Minimum iOS version: 16.x Using ActivityKit for Live Activities No watchOS target in the app Any guidance or recommended approach would be greatly appreciated. Thanks

We’ve been implementing LiveCallerId using OHTTP and have hit a wall with the production environment. The setup works perfectly in TestFlight, but the release version of the app is consistently being rejected by the Apple OHTTP Relay when trying to tunnel traffic to our gateway. Timeline & Status: Applied via the form in September 2025. Received confirmation in November 2025 that our /.well-known/ohttp-keys endpoint was correctly configured. Since then, we've struggled to get a dialogue with Apple to confirm the final production whitelisting. Technical Observations: Our ohttp-keys endpoint is being polled frequently (every few minutes). Based on the traffic, this is clearly the Apple Relay infrastructure fetching/refreshing the keys, not the devices themselves. This suggests the Relay "sees" our configuration, yet it still refuses to tunnel traffic to our gateway in the production environment. Since everything is functional in TestFlight, our implementation seems correct. It feels like there is a configuration mismatch or a missing "production flip" on the Relay side for our Bundle ID. If anyone from the Apple engineering team could verify the status for this Bundle ID, it would be a huge help. We've been stuck in this "TestFlight-only" state for quite a while now.

When my app tries to access a subscription, StoreKit's products(for:) always returns zero results. Similarly, SubscriptionStoreView always shows "Subscription Unavailable" followed by "The subscription is unavailable in the current storefront". The app is a watch-only app (no iPhone companion app). The app and the subscription product were each approved in App Store Connect over two weeks ago. The problem occurs when the app is installed from TestFlight, when the app is installed from the App Store (production), and when run in the Xcode debugger. The only time the app successfully accesses the subscription when simulating it in Xcode with a .storekit file. How should my app access the subscription? Repro: App Store bundle ID: com.toolsay.hoopref Phone app target (unused) bundle ID: com.toolsay.hoopref Watch app bundle ID: com.toolsay.hoopref.watchapp Subscription product ID: com.toolsay.hoopref.pro.annual Subscription availability: All countries and regions App Store listing let products = try await Product.products(for: ["com.toolsay.hoopref.pro.annual"]) products.count is 0.

Hey everyone, I'm developing an iOS only app and want to make sure it can not be installed on iPads. Using Xcode 26, Targets/Appname/General/Supported Destination - I have iPhone only as destination and in the Info.plist I have this: UIDeviceFamily 1 UIRequiredDeviceCapabilities telephony Is there anything else need to do to make sure it can't be installed on iPads? Thanks in advance

Issue: MapKit Snapshot API returning blank dark blue images instead of satellite tiles as of March 4, 2026. This is affecting production and we need urgent assistance. Endpoint: snapshot.apple-mapkit.com/api/v1/snapshot Symptoms: HTTP 200 response with a valid image file, but image is a solid dark navy frame with only the Apple Maps watermark — no satellite data. Occasionally a correct satellite image is returned, but the vast majority are blank. Parameters: t=satellite, 640x640. Confirmed not caused by code changes (none made), auth errors or rate limiting (status is 200), or an invalid image format (image is well-formed, just blank). API keys have been rotated and the issue persists. The intermittent correct responses suggest a backend tile-serving issue on Apple's side rather than anything client-related. Started: March 4, 2026. Same requests that worked prior to this date now consistently fail. Please see the attached sample images for reference. ASAP resolution is appreciated as this is actively impacting production. Thanks, Tristan

Hello Apple Developer Support, We are seeing a payment issue affecting users on iOS 26.3 and 26.4. Many users report that after a successful purchase flow, the purchased content is not delivered in-game. After investigation, we found that storeController?.ConfirmPurchase(pendingOrder); does not always effectively complete the transaction. As a result, the same receipt is sent to the client again on the next purchase attempt or after app restart. This causes repeated pending transactions and prevents users from purchasing the item again. Some affected users requested refunds from Apple, but those requests were rejected. Among 19 reported users: 11 users are on iOS 26.4 (recently upgraded) The remaining users are on iOS 26.3 We also received similar reports on earlier iOS 26 versions. Development environment: Unity Unity In-App Purchasing (IAP) 4.13.0 Could you please help confirm whether there are known StoreKit / transaction completion issues on iOS 26.3+ and suggest the recommended handling for this case? Thank you.

I am using Network framework for connecting two iPad devices that are connected through LAN and has Wifi enabled. I have enabled peerToPeerIncluded. I would like to understand how the framework chooses the interface types for browsing and discovering devices. When I start a browser with browser.run or listener.run, does the browser and advertiser browse and listen on all available interface types? My concern is that if it does in only one interface, Is there a chance that the browser is browsing in one interface(Lets say WiredEthernet) and the listener is listening on another interface(Lets say AWDL) and they dont discover?

We are observing unexpected behavior in Apple Wallet for transactions processed via an online delivery platform. Here is the specific flow: Initial Authorization: The original order was placed for $22.30. Order Amendment: The user added an item 10 minutes later for $6.20, bringing the total to $28.50. The Issue: Apple Wallet only displays the $6.20 transaction. The initial $22.30 amount is not visible in the transaction list. Technical Verification: We confirmed that both backend authorization messages for the original amount and the add-on were approved. We verified that the final settlement amounts correctly reflect the sum of both charges ($28.50). We have confirmed the transaction lifecycle completed successfully on our end. Despite this, the customer only sees the $6.20 entry in their Wallet history, which creates confusion as it doesn't reflect the total spent. Has anyone encountered this sync issue between settlement totals and Wallet display, or is there a specific way we should be linking these related authorizations? Thanks!

We’re evaluating a Bluetooth device that supports Hands Free Profile (HFP) as the “Hands-Free Unit”. You can think of this as a Bluetooth telephone headset. This device interacts with our iOS application. We observed the following. The iPhone 17 HFP Wide-Band Speech (WBS) mSBC decoder requires the WBS packet (H2 header + mSBC frame) to be sent aligned. Aligned meaning, the H2 header must be first in every packet. The WBS packet cannot span multiple eSCO packets or else the iPhone will discard the audio. This is a different implementation than the iPad (iPad Pro 11-inch M4) , presumably due to Apple’s new N1 chip. In other words, we’ve identified that older iPhones and iPads do not require this alignment. They have implemented a stateful parser/decoder of the HFP WBS audio. A quick picture to help illustrate. The iPhone 17 requires: | Frame | Frame | Frame | Frame | However, a Bluetooth implementation we are evaluating does: | me Fra | me Fra | me Fra | me Fra | Does Apple intend to keep this implementation and continue discarding audio frames that are not aligned? Page 115 of the Bluetooth HFP 1.8 specification mentions at the bottom that this behavior is “left up to the implementation” but that the “synchronization header enables unaligned codec audio frames to be recovered by the receiving side.” We understand and acknowledge that one whole frame per eSCO packet is the intended, optimal method for delivering WBS mSBC audio for reduced jitter, latency, and memory usage. However, the more robust solution would be to maintain a stateful receiver as previously implemented. Any input would be appreciated.

We’re having an iPad issue accessing the local network with iPadOS 26.3. We have an automation system that tests our app on an iPad using accessibility tags. the XCTest test code sends messages from the iPad via TCP/IP to setup external test equipment. The messages abruptly stopped transmitting across the iPad blood-brain barrier with iPadOS 26.3 (26.2.1 and earlier works fine). The technique that worked involved installing a helper app with the same bundleID as our app, allowing the helper app to access the network, and when our app runs it has network access through the helper. It’s clever and kludgey. Forums that we referenced in the past: https://developer.apple.com/forums/thread/663858 TN3179: Understanding local network privacy | Apple Developer Documentation I suspect that something was changed in 26.3 that closed our window. I need two things: ID what is different in 26.3 and fix the automation system. If there’s a new way for XCUITest code to access the local network I’m happy to try it out.

Hello Apple Developer Technical Support Team, I’m working on an iOS banking/security SDK and we’re trying to match an Android feature that reads payment cards via NFC (EMV). On Android, this is implemented using an NFC scanning screen (e.g., “NfcScanActivity”) that can read EMV data from contactless credit/debit cards. Could you please clarify the current iOS capabilities and App Store policy around this? On iOS, is it currently possible for a third-party App Store app to read contactless credit/debit cards using Core NFC (i.e., accessing EMV application data/AIDs from payment cards)? If this is possible, what are the supported APIs/frameworks and any entitlement requirements (if applicable)? If this is not possible for App Store apps, could you recommend the closest acceptable alternatives for achieving a similar user outcome? For example: Using Apple Pay / PassKit flows for payment-related experiences Card scanning alternatives (camera-based OCR) for capturing card details (if allowed) Using an external certified card reader accessory (MFi) and required approach/entitlements Any other Apple-recommended approach for “card verification / identification” without reading EMV NFC data Our goal is not to bypass security restrictions, but to provide a compliant solution on iOS comparable to Android’s NFC-based card reading, or to adopt an Apple-approved alternative if direct EMV reading is not supported. If helpful, I can share a brief technical summary of the Android behavior and the exact data we need to obtain (e.g., whether it’s card presence verification vs. reading specific EMV tags). Thank you for your guidance. Best regards, Anis
