Team-scoped keys introduce the ability to restrict your token authentication keys to either development or production environments. Topic-specific keys in addition to environment isolation allow you to associate each key with a specific Bundle ID streamlining key management. For detailed instructions on accessing these features, read our updated documentation on establishing a token-based connection to APNs.

macOS 26 "Tahoe" is allocating much more memory for apps than former macOS versions: A customer contacted me with my app's Thumbnail extension allocating so much memory that her 48 GB RAM Mac Mini ran into "out of application memory" state. I couldn't identify any memory leak in my extension's code nor reproduce the issue, but found the main app allocating as much as 5 times the memory compared to running on macOS 15 or lower. This productive app is explicitly using "Liquid Glass" views as well as implicitly e.g. for an inspector pane. So I created a sample app, just based on Xcode's template of a document-based app, and the issue is still showing (although less dramatically): This sample app allocates 22 MB according to Tahoe's Activity Monitor, while Sequoia only requires 16 MB: macOS 15.6.1 macOS 26.2 Is anyone experiencing similar issues? I suspect some massive leak in Tahoe's memory management, and just filed a corresponding feedback (FB21967167).

We have an app that controls InDesign Desktop and InDesignServer via hundreds of AppleScripts. Some macOS security updates a while back dictated that we start communicating with other apps via ScriptingBridge. We couldn't afford to convert the hundreds of AppleScripts into direct ScriptingBridge nomenclature, so we opted to keep them as is and instead tell the external apps to: [app doScript:<the script text> language:InDesignScLgApplescriptLanguage withArguments:nil undoMode:InDesignESUMScriptRequest undoName:@"blah"] There are a handful of scripts that we did convert to direct ScriptingBridge. There are times (and under the right circumstances, it's repeatable) when a certain script will have run perfectly dozens of times, and then it will throw errOSAInternalTableOverflow. We create a new SBApplication for every job (which could be a single instance of Desktop or the multiple instances of Server). Why is this error happening seemingly randomly? Is there anything we can do to work around or prevent this?

We create custom VPN tunnel by overriding PacketTunnelProvider on MacOS. Normal VPN connection works seamlessly. But if we enable onDemand rules on VPN manager, intemittently during tunnel creation via OnDemand, internet goes away on machine leading to a connection stuck state. Why does internet goes away during tunnel creation?

Hey! Wa are developing a VPN app for iOS and whenever we enable enforceRoutes we see 20% to 30% download and upload speed drop. Here are example results from our environment: | Upload | Download | ------------------------------------------ enforceRoutes off | 337.65 | 485.38 | ------------------------------------------ enforceRoutes on | 236.75 | 357.80 | ------------------------------------------ Is this behavior known and expected? Is there anything we can do to mitigate the effect of enforceRoutes in our application? Test were performed on iOS 26.2.1.

I'm experiencing an issue with the Analytics Reports API. Since last week, no data is being returned from the following endpoint: https://api.appstoreconnect.apple.com/v1/analyticsReports/r2-ac29debd-e528-406d-bdfa-fab6d4403ee2/instances The endpoint responds successfully but returns empty data for the date range where data should exist. Other report endpoints for the same app work correctly. Please investigate why this report stopped delivering data.

In an ObjC framework I'm developing (a dylib) that is loaded into JRE to be used via JNI (Zulu, Graal, or "native image" from Graal+ a JAR) I implemented a naive method that collects current memory footprint of the host process: It collects 5 numbers into a simple NSDictionary with NSString keys (physical footprint, default zone bytes used and allocated, and sums for used and allocated bytes for all zones. The code ran for some time, but at certain point my process started crashing horribly in this method -- at the last line, accessing the dictionary. Here's the code: -(NSDictionary *)memoryState { NSMutableDictionary *memoryState = [NSMutableDictionary dictionaryWithCapacity:8]; // obtain process current physical memory footprint, in bytes. task_vm_info_data_t info; mach_msg_type_number_t count = TASK_VM_INFO_COUNT; kern_return_t kr = task_info(mach_task_self(), TASK_VM_INFO, (task_info_t)&info, &count); [memoryState setObject:(kr == KERN_SUCCESS) ? @(info.phys_footprint) : [NSNull null] forKey:@"physical"]; // obtain process default zone's allocated memory, in bytes. malloc_zone_t *zone = malloc_default_zone(); if (zone!=nil) { malloc_statistics_t st; malloc_zone_statistics(zone, &st); [memoryState setObject:@(st.size_in_use) forKey:@"bytesInUseDefaultZone"]; [memoryState setObject:@(st.size_allocated) forKey:@"bytesAllocatedDefaultZone"]; } uint64_t zone_count = 0, size_in_use =0, size_allocated = 0; vm_address_t *zones = NULL; unsigned int zones_count = 0; kr = malloc_get_all_zones(mach_task_self(), NULL, &zones, &zones_count); if (kr == KERN_SUCCESS && zones != NULL && zones_count > 0) { for (unsigned int i = 0; i < zones_count; i++) { malloc_zone_t *zone = (malloc_zone_t *)zones[i]; if (!zone) continue; malloc_statistics_t st; malloc_zone_statistics(zone, &st); zone_count++; size_in_use += (uint64_t)st.size_in_use; size_allocated += (uint64_t)st.size_allocated; } [memoryState setObject:@(size_in_use) forKey:@"bytesInUseAllZones"]; [memoryState setObject:@(size_allocated) forKey:@"bytesAllocatedAllZones"]; } if (zones != NULL) { vm_deallocate(mach_task_self(), (vm_address_t)zones, zones_count * sizeof(vm_address_t)); } return [memoryState copy]; } my (JRE) process started crashing badly, at the last [memoryState copy]; with crash report I could not understand (looks like an infinite recursion or loop). Any debug log messages (os_log) for this memoryState, its items or its copy would crash the same. Finally I found that commenting out the vm_deallocate() call removes the crash. Sorry to say - I could NOT find anywhere in the documentation anything about malloc_get_all_zones() returned data, and whether I need to deallocate it after use. Some darn AI analyzer pointed out I "had a leak" and that "Apple documentation" which it didn't provide, requires that I thus release this data. 1 ) Do I really have to deallocate the returned "zones" ?? even if I do, something here is strange - zones is a malloc_zone_t ** -- how can it be casted to (vm_address_t)zones Where can I read actual documentation about these low level APIs and the correct use? Thanks!

I have this code in my Virutalization application let process = Process() process.executableURL = URL(fileURLWithPath: "/usr/sbin/diskutil") process.arguments = ["image", "create", "blank", "--fs", "none", "--format", "ASIF", "--size", "2GiB", url.path ] try process.run() process.waitUntilExit() if process.terminationStatus == 0 { print("✅ Disk image creation succeeded.") } else { print("❌ Disk image creation failed with exit code \(process.terminationStatus)") } } catch { print("Process failed to launch: \(error.localizedDescription)") return } this code was working fine until Tahoe 26.2. with the update of 26.3 the system freezes at process.waitUntilExit() The code never exits and i get beech balls. This is working fine with intel macs. i am getting the problem in apple silicon m4 mac mini. Any help would be appreciated.

I see this in Tahoe Beta release notes macOS now supports the Apple Sparse Image Format (ASIF). These space-efficient images can be created with the diskutil image command-line tool or the Disk Utility application and are suitable for various uses, including as a backing store for virtual machines storage via the Virtualization framework. See VZDiskImageStorageDeviceAttachment. (152040832) I'm developing a macOS app using the Virtualization framework and need to create disk images in the ASIF (Apple Sparse Image Format) to make use of the new feature in Tahoe Is there an official way to create/resize ASIF images programmatically using Swift? I couldn’t find any public API that supports this directly. Any guidance or recommendations would be appreciated. Thanks!

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!!

Hi! I recently had an idea to build an iOS app that allows users to create a system-level block of specified web domains by curating a "blacklist" on their device. If the user, for instance, inputs "*example.com" to their list, their iPhone would be blocked from relaying that network traffic to their ISP/DNS, and hence return an error message ("iPhone can't open the page because the address is invalid") instead of successfully fetching the response from example.com's servers. The overarching goal of this app would be to allow users to time-block their use of specified websites/apps and grant them greater agency over their technology consumption, and I thought that an app that blocks traffic at the network level, combined with the ability to control when to/not to allow access, would be a powerful alternative to the existing implementations out there that work more on the browser-level (eg. via Safari extension, which is isolated to the scope of user's Safari browser) or via Screen Time (which can be easy to bypass by inputting one's passcode). Another thing to mention is that since the app would serve as a local DNS proxy (instead of relying on a third party DNS resolver), none of their internet activity will be collected/transmitted off-device and be used for commercial purposes. I feel particularly driven to create a privacy-centered app in this way, since no user data needs to be harvested to implement this kind of filtering. I'd also love to get suggestions for a transparent privacy policy that respects users control over their device. With all this said, I found that the Network Extension APIs may be the only way that an app like this could be built on iOS and, I wanted to ask if the above-mentioned use case of Network Extension would be eligible to be granted access to its entitlement before I go ahead and purchase the $99/year Apple Developer Program membership. Happy to provide further information, and I'd also particularly be open to any mentions of existing solutions out there (since I might have missed some in my search). Maybe something like this already exists, in which case it'd be great to know in any case! :). Thank you so much in advance!

Hello, We are implementing a Transparent Proxy using NETransparentProxyProvider and configuring NETransparentProxyNetworkSettings with NENetworkRule. Currently, NENetworkRule requires: NENetworkRule( destinationHost: NWHostEndpoint(hostname: String, port: String), protocol: .TCP / .UDP / .any ) NWHostEndpoint.port accepts only a single port value (as a String) or an empty string for all ports. At present, we are creating a separate NENetworkRule for each port in the range (ex for range 49152–65535 approximately 16,384 rules). After deploying this configuration, we observe the following behavior: nesessionmanager starts consuming very high CPU (near 100%) The system becomes unresponsive The device eventually hangs and restarts automatically The behavior resembles a kernel panic scenario This strongly suggests that creating thousands of NENetworkRule entries may not be a supported or scalable approach. Questions: Is there any officially supported way to specify a port range in NENetworkRule? Is creating thousands of rules (one per port) considered acceptable or supported? Is the recommended design to intercept broadly (e.g., port = "") and filter port ranges inside handleNewTCPFlow / handleNewUDPFlow instead? Are there documented system limits for the number of NENetworkRule entries allowed in NETransparentProxyNetworkSettings?

Dear Apple Support Team, Thank you for your continued support. I would like to inquire about the behavior of CallKit. Our company provides an office PBX extension phone application (iPhone app). When the iPhone is placed into sleep mode (screen off) and our app receives an incoming call, the following sequence sometimes results in an audio playback panel appearing at the bottom of the lock screen for a few seconds after the call ends(See attachment file for detail). Sequence to reproduce the issue: Put the iPhone into sleep mode (screen off). Receive an incoming call to our extension phone app. CallKit incoming call screen appears. Answer the call. Conduct the call. End the call from the peer. iOS versions with confirmed behavior: iOS 26.0: Not observed. iOS 26.2: Observed. iOS 26.3: Not observed. This behavior does not affect the call functionality itself; however, some users report that the temporary appearance of the audio playback panel feels unusual. If there is any known reason for this behavior or any recommended workaround, we would greatly appreciate your guidance. Additionally, if this is a known issue that was addressed in iOS 26.3, we would appreciate any information you can provide regarding that as well. Thank you very much for your assistance.

I am getting bug reports from users that occasionally the AlarmKit alarms scheduled by my app are going off exactly at midnight. In my app, users can set recurring alarms for sunrise/sunset etc. I implement this as fixed schedule alarms over the next 2-3 days with correct dates pre-computed at schedule time. I have a background task which is scheduled to run at noon every day to update the alarms for the next 2-3 days. Are there any limitations to the fixed schedule which might be causing this unintended behavior of going off at midnight?

Hi, Submitted Family Controls entitlement request a month ago for my main focus app, got approved within a day. Submitted 3 more requests for my extensions, and it has been 16 days without any word. Saw advice to file a code-level support with DTS in this similar forum: https://developer.apple.com/forums/thread/812934 Is there anything else I can do before filing a code-level support? Any extra info to provide? If not, can a DTS engineer please refer me for the code-level support? Thanks!

Hi :) I'm new to app store connect, and I just want to verify what does it take to be able to test subscription for a new app that isn't approved yet using sandbox? Or is this not possible that the app has to be approved first? More context below: My app is a new app, I only submitted for review and I linked the subscription from the app’s In-App Purchases and Subscriptions section on the version page when submit it for review. It got rejected for now. When the app review status is both in-review and rejected, I've tried to test my subscription, where there is a button (like "subscribe"/"become a member") in my app that user can click on, which it calls ios's IAPProvider.startMembershipPurchase, I just get Error: [IAPService] Product not found: [<my_subscription_id>]. I ensured my subscription's product id in app store connect matches with the one in my code. I can see the "rejected" status both on my app and the subscription. So can anyone help clarify if the app has to be approved first in order to test subscription? Or am I missing any other setup? Or it might just be my code? Thanks in advance! Any info is super helpful!

Hello, I am using CLLocationManager to monitor multiple CLBeaconRegion instances (up to 20). When the app is terminated by the system (not force-quit) and a region enter event occurs, the app is relaunched in the background. I have two questions: What is the expected execution time window after relaunch before the app is suspended again? Is it supported to start short CoreBluetooth operations (e.g., scanning or connecting briefly) within this window? I understand that force-quitting the app disables background relaunch, so this question applies only to system-terminated apps.

Hello, thanks for your effort! I found that when showsUserLocation is set to true (by default), the pulsing blue dot user location annotation is shown, which is cool and beautiful. However, it will automatically and periodically attempt to call the Apple Server API GET https://api.apple-mapkit.com/v1/reverseGeocode within userLocationDidChange() and updateUserLocationAnnotation() to display, I assume, the user's current address when single-tapping on the blue dot. It will significantly use the MapKit service calls quota since the user location is automatically updated. It almost runs out of quota even though the map initialization is plenty enough. Is there any way to disable the bubble behavior but preserve the user location blue dot, which is lovely and better than drawing my own user location dot? It seems I can only turn off all user location features. Many thanks!

Not quite but maybe sorta related to the errOSAInternalTableOverflow problem I asked about in a different thread, this one deals with crashes our app gets (and much more frequently lately after recent OS updates (15.7.3) are OK'd by our IT department). Our app can run multiple jobs concurrently, each in their own NSOperation. Each op creates its own SBApplication instance that controls unique instances of InDesignServer. What I'm seeing recently is lots of crashes happening while multiple ops are calling into ScriptingBridge. Shown at the bottom is one of the stack crawls from one of the threads. I've trimmed all but the last of our code. Other threads have a similar stack crawl. In searching for answers, Google's AI overview mentions "If you must use multiple threads, ensure that each thread creates its own SBApplication instance…" Which is what we do. No thread can reach another thread's SBApplication instance. Is that statement a lie? Do I need to lock around every ScriptingBridge call (which is going to severely slow things down)? 0 AE 0x1a7dba8d4 0x1a7d80000 + 239828 1 AE 0x1a7d826d8 AEProcessMessage + 3496 2 AE 0x1a7d8f210 0x1a7d80000 + 61968 3 AE 0x1a7d91978 0x1a7d80000 + 72056 4 AE 0x1a7d91764 0x1a7d80000 + 71524 5 CoreFoundation 0x1a0396a64 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 6 CoreFoundation 0x1a03969f8 __CFRunLoopDoSource0 + 172 7 CoreFoundation 0x1a0396764 __CFRunLoopDoSources0 + 232 8 CoreFoundation 0x1a03953b8 __CFRunLoopRun + 840 9 CoreFoundation 0x1a03949e8 CFRunLoopRunSpecific + 572 10 AE 0x1a7dbc108 0x1a7d80000 + 246024 11 AE 0x1a7d988fc AESendMessage + 4724 12 ScriptingBridge 0x1ecb652ac -[SBAppContext sendEvent:error:] + 80 13 ScriptingBridge 0x1ecb5eb4c -[SBObject sendEvent:id:keys:values:count:] + 216 14 ScriptingBridge 0x1ecb6890c -[SBCommandThunk invoke:] + 376 15 CoreFoundation 0x1a037594c ___forwarding___ + 956 16 CoreFoundation 0x1a03754d0 _CF_forwarding_prep_0 + 96 17 RRD 0x1027fca18 -[AppleScriptHelper runAppleScript:withSubstitutionValues:usingSBApp:] + 1036
