URLSession question

The AppIntent feature is available on tvOS since OS 16. https://developer.apple.com/documentation/appintents I tried a real basic integration where I just want simply open a specific tab in my tabbar. But the perform action gets never called. Is it really possible already to use AppIntent on tvOS? Or is this feature still mostly targeted for mobile devices? Also, the documentaiton says so often something about shortcuts app and features, that are not available on tvOS, that I started doubting that the AppIntent is really usable on tvOS. If AppIntents are available and usable for tvOS, what could be wrong, so that I do not see the expected results?

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

Hello team, We are using below example https://github.com/apple/pir-service-example as a starting point to setup PIR server for our backend, but I am not really understanding what else we need in this example to configure OHTTP gateway. Any help will be appreciated.

We're developing a Mac App Store application that embeds the V8 JavaScript engine (via Electron). The application has shipped successfully on macOS 15.x with the following entitlements: com.apple.security.app-sandbox = true com.apple.security.cs.allow-jit = true com.apple.security.cs.allow-unsigned-executable-memory = true com.apple.security.cs.disable-library-validation = true On macOS 26 Tahoe, the exact same signed binary crashes deterministically within ~1.5 seconds on Apple Silicon with EXC_BREAKPOINT (SIGTRAP), ESR 0xf2000000. The crash is in V8's background JIT compilation thread when it attempts to manage memory page protections (transitioning pages between Read-Write and Read-Execute states via mprotect). The crash does not occur in these configurations: macOS 26 + App Sandbox + Intel x86_64 — works macOS 26 + Hardened Runtime (no sandbox) + ARM64 — works macOS 15.x + App Sandbox + ARM64 — works This appears to be a regression in how the XNU kernel handles mprotect calls for sandboxed processes on ARM64 under macOS 26, specifically in the context of the allow-jit entitlement. Has the behavior of allow-jit changed in macOS 26 with respect to runtime code generation memory management on ARM64? Is there a new API or entitlement that V8-style JIT engines should use instead of mprotect-based RW↔RX page transitions?

I'm relatively new to socket networking, and am migrating an older project from CocoaAsyncSocket to Swift's native Network. The project utilises GCDAsyncUdpSocket.enableBroadcast(_ flag: Bool), but I don't know how to replicate this in Network. How do I enable UDP Broadcast on NWConnection?

I've looked around quite a bit at the EventKit documentation and done all the searching I could think of, as well as examining the EKCalendar and EKEventStore types. Trying to find out how to view, modify, and create groups of reminders lists.

I am trying to provide my clients with subscribable calendar link so they can see their schedules from an App I have. I've got the basics working on building out the various fields for the VEVENT, however no matter what I have tried the LOCATION is always showing up as a text and not a location within Apple Maps that I can have them click on from the event. Any idea what the best way to go about this would be, and feeding the ICS an address, Apple Maps URL, GPS coordinates either in the location, Geo or the X-APPLE-STRUCTURED-LOCATION or combinations haven't been working. I am using/hosting on Google Scripts.

StoreKit2 Repro Notes: the latest renewal appears in Transaction.unfinished after restore (2026-04-05) 1. Issue Summary In the current project, during a normal cold launch: Transaction.latest(for:) returns a value for the weekly subscription Transaction.all returns the full subscription history chain Transaction.unfinished is empty However, after tapping Restore Purchases and calling AppStore.sync(), one "latest renewal" transaction appears in Transaction.unfinished. This behavior looks more like a system-side replay triggered by AppStore.sync() than a consistently unfinished transaction during a normal launch. 2. Affected Product Product: do.i.iapc.vip.week Transaction chain characteristics: All transactions belong to the same auto-renewable subscription chain originalTransactionID = 2000001143446796 The transaction that appears in unfinished is usually the latest or last renewal in the chain 3. Current Code Path During app startup: loadProducts() Debug snapshot for Transaction.latest(for:) Debug snapshot for Transaction.all Scan Transaction.unfinished refreshEntitlements() During restore purchases: Call AppStore.sync() Scan Transaction.unfinished refreshEntitlements() 4. Preconditions A Sandbox test account is used The weekly subscription do.i.iapc.vip.week already has multiple historical renewal transactions The subscription is already expired, so entitlements = 0 during a normal launch The issue is easier to reproduce on an iOS 26.4 device The issue was not consistently reproduced on another iOS 18.2 device 5. Reproduction Steps Path A: Normal cold launch Launch the app Observe the logs: LatestTransaction snapshot AllTransaction snapshot summary unfinished processing result Observed result: latest has a value all contains the full history chain unfinishedHandledCount = 0 Path B: Tap Restore Purchases Launch the app Tap Restore Purchases Trigger AppStore.sync() Observe the logs: restore started unfinished processing started unfinished transaction received Observed result: After restore, one "latest renewal" transaction appears in unfinished That same transaction does not necessarily appear during a normal cold launch 6. Expected Result If a transaction has already been successfully finished in the past, it should not appear again as unfinished after Restore Purchases. A stricter expectation is: During a normal cold launch, unfinished = 0 After tapping Restore Purchases, unfinished should still remain 0 7. Actual Result Actual behavior: Normal cold launch: unfinished = 0 After Restore Purchases: one "latest renewal" transaction appears again in unfinished This suggests that AppStore.sync() may replay the most recent historical subscription transaction. 8. Current Assessment Based on the current logs, the issue is more likely to be: Related to AppStore.sync() / StoreKit / Sandbox replay behavior on the system side Easier to reproduce on iOS 26.4 Less likely to be caused by a persistent app-side bug where finish() is missed during a normal startup flow Reasons: During a normal launch, unfinished = 0 The behavior is inconsistent across devices and OS versions, even with the same Sandbox account latest, all, and unfinished can be clearly separated during a normal cold launch 9. Suggested Engineering Position Suggested wording for internal or external communication: In the iOS 26.4 + Sandbox environment, calling AppStore.sync() may cause StoreKit to replay the latest historical subscription transaction into Transaction.unfinished. Since the same transaction does not necessarily appear during a normal cold launch, the issue currently looks more like a system/environment-specific behavior difference than an app-side bug where finish() is consistently missed during the regular startup path. 10. Additional Evidence That Can Be Collected If this needs to be escalated to the team or to Apple, the following would strengthen the report: Full log comparison before and after tapping Restore Purchases The same transactionId compared between normal launch and post-restore behavior Cross-device comparison on different iOS versions A minimal reproducible sample project and Sandbox test record

The most recent KDK for MacOS Sequoia that appears in the Downloads is for MacOS 15.5 (24F74), but the current version of MacOS Sequoia is 15.6 (24G84) and 15.7 (24G207) is in RC. Is there an ETA for the KDKs for 15.6 (24G84) and 15.7 (24G207) to be made available to download? Many thanks for any help.

Hi everyone! I’m building Delta — an app designed to rethink time, because time is literally our most valuable currency. So the core mechanic involves earning time in useful apps and then spending it on apps that are a distraction. I already have a prototype that’s being actively tested in a closed beta, but I’ve started noticing that more and more testers are reporting the same bug. “Time is being counted even when I'm not in the app I marked as useful.” I suspect that Screen Time is also tracking background time, although this behavior isn't correct for my app. Does anyone know how to track specifically those moments when an app marked as useful and used for “time-earning” is in the foreground? Additionally, I hit a wall with Screen Time and had to accept that I can’t force a user away from another app if they’re active there, nor redirect them to my app to trigger the lock screen. Because of this, I had to resort to a penalty system, which is equal to the time the user spent additionally after their time ran out. And here, I run into the same problem I described at the beginning of the post. I can’t track the background status of another app, even though I’m trying really hard... Can anyone suggest any ways I can get out of this situation, or should I keep looking for a solution, or shift toward explaining this to the user?.. (However, I’m holding out until the very end before giving up on finding a solution)

Hi all, I’m trying to determine whether the loudness gap I’m seeing between AlarmKit alert playback and normal app-managed playback is expected behavior, a sound-asset issue, or something that should be reported as a bug. Observed behavior When an alarm fires through AlarmKit while the device is locked, the alarm sound is significantly quieter than playback of the same or very similar audio once the app is active and using its own audio session. The difference is large enough that it does not feel like a small mastering difference. It feels like the AlarmKit / system alerting path is using a meaningfully lower effective output level than normal app playback. Test scenario My repro is roughly: Schedule an alarm with AlarmKit. Lock the device. Let the alarm fire and listen during the system alerting phase. Enter the app / continue into the app-driven alarm experience. Play the same or equivalent alarm asset via app-managed playback. Result: AlarmKit / lock-screen alerting phase sounds much quieter. In-app playback sounds noticeably louder and fuller on the same device. Current implementation Alarm flow is currently split into two paths: 1) System alarm path Alarm scheduling and alert surfacing via AlarmKit Device may be locked No attempt to manipulate system volume No private APIs 2) In-app playback path After app activation, playback uses: AVAudioSession category .playback AVAudioPlayer Audio is routed as normal app playback This path sounds substantially louder than the AlarmKit path Important detail I am not asking how to override system volume. I understand that AlarmKit appears to follow the system ringer / alert volume model and does not expose a public API for custom alarm loudness. My question is narrower: Is it expected that the same asset or an equivalent asset will sound materially quieter during the AlarmKit alerting phase than during ordinary app playback with AVAudioSession(category: .playback)? Questions Is the lower perceived loudness during AlarmKit alerting an expected property of the framework / system alarm path? Does AlarmKit playback use a different output path, gain policy, processing chain, or speaker treatment than normal app playback with .playback? Are there recommended authoring constraints for AlarmKit alarm sounds to maximize perceived loudness on iPhone speakers? transient-heavy mix stronger mids reduced low-end different LUFS / peak strategy shorter attack, etc. Has anyone measured this directly with: the same WAV / CAF file same device same system volume locked AlarmKit playback vs unlocked in-app playback If this is not expected, would Apple want this reported as a bug with: sample project exact iOS version device model screen recording / audio recording What I’m trying to figure out For alarm-app UX, this matters a lot because: AlarmKit is the most reliable lock-screen/system path. But if AlarmKit playback is substantially quieter than normal app playback, the alarm experience is inconsistent depending on device/app state. That makes it hard to know whether to treat this as: expected system behavior, a framework limitation, an asset/mastering problem, or a bug. If anyone has tested this in a controlled way or received guidance from Apple/DTS, I’d appreciate any technical detail. Thanks.

noticed something here, dont underasand why. but here in Retrieve the registrations for a device in Apple Developer Documentation in Retrieve the registrations for a device. There is no Authorization in the header to include, however, other endpoints support that? Is this header will be sent from Walle? meaning that it has been missed in the documentation ? https://developer.apple.com/documentation/walletorders/retrieve-the-registrations-for-a-device

I cannot find anywhere in the documentation how to invalidate an FSItem. It seems to be cached indefinitely or am I missing something?

Hello, I am currently developing a headless macOS daemon (HarmonBridge) that requires extremely low-latency, high-bandwidth UDP video streaming between a Mac and a Linux host over a dedicated 2.5GbE/5GbE local network link. We are utilizing widely available Realtek RTL8156 / RTL8156B based USB 2.5G network adapters. Under macOS, these adapters default to the generic com.apple.DriverKit.AppleUserECM driver. The hardware itself natively supports Jumbo Frames (MTU 9000), but the DriverKit implementation artificially restricts the MTU cap to 1500 bytes. Because we are forced through MTU 1500, we are incurring significant performance penalties: Excessive IP fragmentation for our large UDP video payloads. Unnecessary CPU overhead due to increased hardware interrupts and header processing at 2.5Gbps speeds. For a latency-critical application like ours, reducing CPU interrupts and utilizing true hardware-level Jumbo Frames is essential. My Questions: Is there an undocumented boot-arg or network sysctl parameter that permits overriding the AppleUserECM 1500 MTU hard-limit for 2.5G USB adapters on Apple Silicon? Are there any roadmap plans from the DriverKit/Networking team to re-enable standard Jumbo Frame negotiation for RTL8156 hardware using the generic ECM driver? If the answer to both is no, does Apple grant NetworkingDriverKit Entitlements to independent developers specifically for the purpose of writing custom hardware overrides to patch missing MTU features in the default ECM stack? Because AppleUserECM effectively acts as a gatekeeper to the underlying MAC/PHY capabilities of these modern USB NICs, any guidance on achieving wire-native MTU 9000 under the current DriverKit paradigm would be hugely appreciated. Thank you!

I’m experiencing a confusing issue with App Store Server Notifications (Version 2) in the Sandbox environment. I've configured my Sandbox URL, but I'm not receiving any notifications despite successful API responses. App Details: App ID: 6753059790 Bundle ID: com.xmojong.widgetTest Sandbox URL: https://webhook.site/97938287-07e8-4482-a053-b6ccfca76634 The Problem: I am calling the requestTestNotification endpoint via the App Store Server API. The API call is successful and consistently returns a 200 OK status code. However, no notification (Type: TEST) is ever delivered to my Webhook.site endpoint. What I've verified: Endpoint Accessibility: I tested the Webhook URL by sending a manual POST request directly from my iOS app; it was received instantly. Configuration: The URL is correctly entered in the Sandbox Server URL field (not Production) in App Store Connect. Notification Version: It is set to Version 2. Propagation Time: It has been over 3 hours since I updated the URL and saved the changes in App Store Connect. JWT Token: The JWT for the API call is valid (verified by the 200 response from Apple). My Question: If the requestTestNotification API returns a 200, doesn't that mean the App Store server has successfully queued the notification for my specific URL? Is there a known delay for Sandbox notification delivery or URL propagation recently? Or are there any hidden requirements for the Sandbox environment that I might have missed? Any help or insights would be greatly appreciated! Thanks in advance!

Hello, I am developing a macOS Launch Daemon (packaged as a bundle) that acts as an XPC server. For debugging purposes, I am trying to run the daemon's executable directly from the terminal via sudo ./mydaemon.app/Contents/MacOS/myexecutable. Initially, I added the com.apple.security.application-groups entitlement to the daemon. However, when starting the process, it failed to create the XPC service with the following errors: Unsatisfied entitlements: com.apple.security.application-groups Soft-restriction provisioning profile validation failure: Error Domain=AppleMobileFileIntegrityError Code=-413 "No matching profile found" UserInfo={NSURL=, unsatisfiedEntitlements=, NSLocalizedDescription=No matching profile found} listener failed to activate: xpc_error=[1: Operation not permitted] To resolve the profile validation failure, I registered a new App Group in the Apple Developer Portal, generated a new provisioning profile for the daemon that includes this group, and embedded it into the bundle (Contents/embedded.provisionprofile). Now, the previous profile error is gone, but I am getting a new identity conflict error, and the XPC listener still fails: Two equal instances have unequal identities. <anon<myproc_name>(501) pid=2818 AUID=501> and <anon<myproc_name>(501)(262) pid=2818 AUID=262> listener failed to activate: xpc_error=[1: Operation not permitted] My questions are: What exactly causes the Two equal instances have unequal identities error? I noticed the Audit UID difference (AUID=501 vs AUID=262). Why does NSXPCListener still fail with Operation not permitted? What is the recommended workflow for debugging a Launch Daemon that requires an App Group provisioning profile for XPC communication? Thank you in advance!

I'm implementing a NEDNSProxyProvider on macOS 15.x and macOS 26.x. The flow works correctly up to the last step — returning the DNS response to the client via writeDatagrams. Environment: macOS 15.x, 26.x Xcode 26.x NEDNSProxyProvider with NEAppProxyUDPFlow What I'm doing: override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool { guard let udpFlow = flow as? NEAppProxyUDPFlow else { return false } udpFlow.readDatagrams { datagrams, endpoints, error in // 1. Read DNS request from client // 2. Forward to upstream DNS server via TCP // 3. Receive response from upstream // 4. Try to return response to client: udpFlow.writeDatagrams([responseData], sentBy: [endpoints.first!]) { error in // Always fails: "The datagram was too large" // responseData is 50-200 bytes — well within UDP limits } } return true } Investigation: I added logging to check the type of endpoints.first : // On macOS 15.0 and 26.3.1: // type(of: endpoints.first) → NWAddressEndpoint // Not NWHostEndpoint as expected On both macOS 15.4 and 26.3.1, readDatagrams returns [NWEndpoint] where each endpoint appears to be NWAddressEndpoint — a type that is not publicly documented. When I try to create NWHostEndpoint manually from hostname and port, and pass it to writeDatagrams, the error "The datagram was too large" still occurs in some cases. Questions: What is the correct endpoint type to pass to writeDatagrams on macOS 15.x, 26.x? Should we pass the exact same NWEndpoint objects returned by readDatagrams, or create new ones? NWEndpoint, NWHostEndpoint, and writeDatagrams are all deprecated in macOS 15. Is there a replacement API for NEAppProxyUDPFlow that works with nw_endpoint_t from the Network framework? Is the error "The datagram was too large" actually about the endpoint type rather than the data size? Any guidance would be appreciated. :-))
