I have the following code that is attempting to set up Hotspot 2.0 using an EAP-TLS configuration. I am importing a pk12 file and using those certificates. I have tried all manner of permutations for the configuration, and have narrowed down all the errors I was getting and now I am just getting a generic: Error: invalid EAP settings. I have tried adding the identity separately and either get an entitlements issue which I can't figure out why since I have added the required network extension sharing groups, or a duplicate item error, meaning it was already correctly added. The certificate and configuration are correctly working through an Android app already. static let accessGroup: String? = { guard let prefix = Bundle.main.object(forInfoDictionaryKey: "AppIdentifierPrefix") as? String else { print("Could not load group") return nil } return "\(prefix)com.apple.networkextensionsharing" }() static func setupHotspot(data: CertificateData) { let h20 = NEHotspotHS20Settings(domainName: data.realm, roamingEnabled: false) h20.naiRealmNames = [data.realm] var result: CFArray? let options: [CFString: Any] = [ kSecImportExportPassphrase: "**********", kSecAttrLabel: "ident:\(data.user)", kSecAttrAccessGroup: accessGroup!, kSecReturnPersistentRef: true ] let status = SecPKCS12Import(data.p12 as CFData, options as CFDictionary, &result) guard status == errSecSuccess, let importResult = result as?

I'm trying to implement Unwanted SMS and Calls reporting in an app I'm doing in my idle time. If I place a UITextField or UITextView inside a ILClassificationUIExtensionViewController, every time I select on such control the extension crashes without any logs. The closet idea I have on why it crashes it has something to do with iOS requesting the dictation feature. I'm using the latest (beta 8 at the time) iOS 16.0 beta on my iPhone 13 pro. Attaching my code here if you want to try for yourself: github

Hello dear Apple Platform Engineers, I'm working on an iOS App that connects to a Bluetooth Low Energy Peripheral in the foreground. Whenever the App moves into Background, we want to continue syncing data & therefore implemented State Restoration to be informed about Discovery, Connect, Disconnect or Characteristic changes in the Background in order to wake the App up whenever it was "Terminated due to memory issue". I consulted https://developer.apple.com/library/archive/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html#//apple_ref/doc/uid/TP40013257-CH7-SW1 for this & assigned: CBCentralManagerOptionRestoreIdentifierKey Reinstantiate the dedicated CentralManager & implemented the centralManager(_ central: CBCentralManager, willRestoreState dict: [String : Any]) Delegate Additionally, I assigned the following keys on connect(_ peripheral: CBPeripheral, options: [String : Any]? = nil) CBConnectPeripheralOptionNotifyOnConnectionKey CBConnectPeripheralOptionNotifyOnDisconnectionKey CBConnectPeripheralOptionNotifyOnNotificationKey However, from my experience the App gets woken up, but neither the willRestoreState nor the didDiscover, didConnect or didDisconnectPeripheral is called even though launchOptions?[UIApplication.LaunchOptionsKey.bluetoothCentrals] as? [String] is not empty. What might I be missing when trying to make this approach work? Thanks a lot for any insights & support!

The production macOS build is showing severe performance problems, while Mac_Dev performs normally. Observed behavior in production Mac build: Issue board scrolling becomes inconsistent or nearly unusable Changing an issue status in detail view is very slow Scrolling the status menu/options can be slow Typing in issue description/notes fields becomes sluggish Dragging issues between milestones/statuses on the board can lag badly Observed behavior in Mac_Dev: Board scrolling is smooth Status changes are immediate Typing in description fields is responsive Drag/drop between milestones works well Important comparison: Mac_Dev appears to run against an isolated local SwiftData store Production Mac app uses the normal CloudKit-backed store Because the same UI is fast in Mac_Dev, this does not look like a pure rendering problem Most likely cause is production store / CloudKit sync churn amplifying existing SwiftUI invalidation and save behavior Current hypothesis: The production app is saving or observing live Issue mutations too aggressively Detail view edits and some quick actions may be causing repeated saves / broad view invalidation Cloud-backed persistence likely makes the problem much worse than the isolated dev store The UI architecture may still need cleanup, but the production data lane is likely a major factor Any help in understanding how best to address this would be helpful.

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. :-))

Problem description Since macOS Sequoia, our users have experienced issues with multicast traffic in our macOS app. Regularly, the app starts but cannot receive multicast, or multicast eventually stops mid-execution. The app sometimes asks again for Local Network permission, while it was already allowed so. Several versions of our app on a single machine are sometimes (but not always) shown as different instances in the System Settings > Privacy & Security > Local Network list. And when several instances are shown in that list, disabling one disables all of them, but it does not actually forbids the app from receiving multicast traffic. All of those issues are experienced by an increasing number of users after they update their system from macOS 14 to macOS 15 or 26, and many of them have reported networking issues during production-critical moments. We haven't been able to find the root cause of those issues, so we built a simple test app, called "FM Mac App Test", that can reproduce multicast issues. This app creates a GCDAsyncUdpSocket socket to receive multicast packets from a piece of hardware we also develop, and displays a simple UI showing if such packets are received. The app is entitled with "Custom Network Protocol", is built against x86_64 and arm64, and is archived (signed and notarized). We can share the source code if requested. Out of the many issues our main app exhibits, the test app showcases some: The app asks several times for Local Network permission, even after being allowed so previously. After allowing the app's Local Network and rebooting the machine, the System Settings > Privacy & Security > Local Network does not show the app, and the app asks again for Local Network access. The app shows a different Local Network Usage Description than in the project's plist. Several versions of the app appear as different instances in the Privacy list, and behave strangely. Toggling on or off one instance toggles the others. Only one version of the app seems affected by the setting, the other versions always seem to have access to Local Network even when the toggle is set to off. We even did see messages from different app versions in different user accounts. This seems to contradicts Apple's documentation that states user accounts have independent Privacy settings. Can you help us understand what we are missing (in terms of build settings, entitlements, proper archiving...) so our app conforms to what macOS expects for proper Local Network behavior? Related material Local Network Privacy breaks Application: this issue seemed related to ours, but the fix was to ensure different versions of the app have different UUIDs. We ensured that ourselves, to no improvement. Local Network FAQ Technote TN3179 Steps to Reproduce Test App is developed on Xcode 15.4 (15F31d) on macOS 14.5 (23F79), and runs on macOS 26.0.1 (25A362). We can share the source code if requested. On a clean install of macOS Tahoe (our test setup used macOS 26.0.1 on a Mac mini M2 8GB), we upload the app (version 5.1). We run the app, make sure the selected NIC is the proper one, and open the multicast socket. The app asks us to allow Local Network, we allow it. The alert shows a different Local Network Usage Description than the one we set in our project's plist. The app properly shows packets are received from the console on our LAN. We check the list in System Settings > Privacy & Security > Local Network, it includes our app properly allowed. We then reboot the machine. After reboot, the same list does not show the app anymore. We run the app, it asks again about Local Network access (still with incorrect Usage Description). We allow it again, but no console packet is received yet. Only after closing and reopening the socket are the console packets received. After a 2nd reboot, the System Settings > Privacy & Security > Local Network list shows correctly the app. The app seems to now run fine. We then upload an updated version of the same app (5.2), also built and notarized. The 2nd version is simulating when we send different versions of our main app to our users. The updated version has a different UUID than the 1st version. The updated version also asks for Local Network access, this time with proper Usage Description. A 3rd updated version of the app (5.3, also with unique UUID) behaves the same. The System Settings > Privacy & Security > Local Network list shows three instances of the app. We toggle off one of the app, all of them toggle off. The 1st version of the app (5.1) does not have local network access anymore, but both 2nd and 3rd versions do, while their toggle button seems off. We toggle on one of the app, all of them toggle on. All 3 versions have local network access.

Development environment: Xcode 26.4, macOS 26.3.1 Run-time configuration: iOS 18.7.6 and higher We have an application running on supervised devices, with an MDM profile typically deployed via jamf. The profile enables a Content Filter, with the two flags "Socket Filter" and "Browser Filter" set to true. On the device side, we implement the content filter as a network extension via: a class FilterDataProvider extending NEFilterDataProvider, a class FilterControlProvider extending NEFilerControlProvider. For the record, the FilterDataProvider overrides the handle*() methods to allow all traffic; the handleNewFlow() simply reports the new connection to FilterControlProvider for analysis. Problem: some customers reported that after a reboot of their device, they would not get access to the internet for up to 60s/90s. We have not been able to reproduce the problem on our own devices. What we see is that, even with our app uninstalled, without any Content Filter, it takes roughly 20s to 25s for a device to have internet access, so we can probably consider this 20s delay as a baseline. But would you be aware of a reason that would explain the delay observed by these customers? More details: We have conducted some tests on our devices, with extended logging. In particular: we have added an internet probe in the app that is triggered when the app starts up: it will try to connect to apple.com every 2s and report success or failure, we also have a network monitor (nw_path_monitor_set_update_handler) that reacts to network stack status updates and logs the said status. A typical boot up sequence shows the following: the boot time is 7:59:05, the app starts up at 7:59:30 (manually launched when the device is ready), the probe fails and keeps failing, the content filter is initialized/started up 7:59:53 and is ready at 7:59:55, the network monitor shows that the network stack is connected (status = nw_path_status_satisfied) right after that, and the probe succeeds in connecting 2s later. In other words, internet is available about 50s after boot time, 25s after app startup (i.e. after the device is actually ready). For some customers, this 25s delay can go up to 60/90s.

I’m working on an iOS Network Extension where a NEPacketTunnelProviderconfigures a local HTTP/HTTPS proxy usingNEPacketTunnelNetworkSettings.proxySettings. Per NEProxySettings.exceptionList docs: If the destination host name of an HTTP connection matches one of these patterns then the proxy settings will not be used for the connection. However, I’m seeing two distinct issues: Issue A (exception bypass not working): HTTPS traffic to a host that matches exceptionList still reaches the proxy. Issue B (domain-scoped proxy not applied): When matchDomains is set to match a specific domain (example: ["googlevideo.com"]), I still observe its traffic in some apps is not proxied. If I remove the domain from matchDomains, the same traffic is proxied. Environment OS: iOS (reproduced with 26.4 and other versions) Devices: Reproduced with several iPhones (likely iPads as well) Xcode: 26.3 Extension: NEPacketTunnelProvider Minimal Repro (code) This is the minimal configuration. Toggle between CONFIG A / CONFIG B to reproduce each issue. import NetworkExtension final class PacketTunnelProvider: NEPacketTunnelProvider { override func startTunnel( options: [String : NSObject]? = nil, completionHandler: @escaping (Error?) -> Void ) { let proxyPort = 12345 // proxy listening port let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "8.8.8.8") let proxySettings = NEProxySettings() proxySettings.httpEnabled = true proxySettings.httpsEnabled = true proxySettings.httpServer = NEProxyServer(address: "1.2.3.4", port: proxyPort) // proxy listening address proxySettings.httpsServer = NEProxyServer(address: "1.2.3.4", port: proxyPort) // proxy listening address // CONFIG A: proxy all domains, but exclude some domains // proxySettings.matchDomains can be set to match all domains // proxySettings.exceptionList = ["*.cdninstagram.com", "cdninstagram.com"] // CONFIG B: proxy only a specific domain // proxySettings.matchDomains = ["googlevideo.com"] settings.proxySettings = proxySettings setTunnelNetworkSettings(settings) { error in completionHandler(error) } } } Repro steps Issue A (exceptionList bypass not working) Enable the VPN configuration and start the tunnel with CONFIG A (exceptionList = ["*.cdninstagram.com", "cdninstagram.com"]). Open the Instagram app to trigger HTTPS connections to *.cdninstagram.com Inspect proxy logs: cdninstagram.com traffic is still received by the proxy. Safari comparison: If I access URLs that trigger the same *.cdninstagram.com hosts from Safari, it can behave as expected. When the traffic is triggered from the Instagram app, the excluded host still reaches the proxy as CONNECT, which is unexpected. Issue B (matchDomains not applied for YouTube traffic) Start the tunnel with CONFIG B (matchDomains = ["googlevideo.com"]). Open the YouTube app and start playing a video (traffic typically targets *.googlevideo.com). Inspect proxy logs: googlevideo.com traffic is not received by the proxy. Remove the host from matchDomains and observe that googlevideo.com traffic is received by the proxy. Safari comparison: If I access a googlevideo.com host from Safari while matchDomains = ["googlevideo.com"], it behaves as expected (proxied). In contrast, the YouTube app’s googlevideo.com traffic is not proxied unless I match all domains. Expected Issue A Connections to *.cdninstagram.com in the Instagram app should not use the proxy and should not reach the local proxy server. Issue B With matchDomains = ["googlevideo.com"], traffic to *.googlevideo.com (YouTube video traffic) should be proxied and therefore reach the local proxy. Actual Issue A The local proxy still receives the request as: CONNECT scontent-mad1-1.cdninstagram.com:443 HTTP/1.1 So the bypass does not happen. Issue B With matchDomains = ["googlevideo.com"], I still observe googlevideo.com traffic in the YouTube app that is not delivered to the proxy. When all traffic is proxied, the same traffic is delivered to the proxy.

I've been working on an app. It uses iCloud syncing. 48 hours ago everything was working 100%. Make a change on the iPhone it immediately changed on the Mac. Change on the Mac, it immediately changed on the iPhone. I didn't work on it yesterday. I updated to iOS26.4 on the iPhone and 26.4 on the Mac yesterday instead. Today, I pull up the project again. I made NO changes to the code or settings. Make a change on the iPhone it immediately updates on the Mac. Make a change on the Mac, nothing happens on the iPhone. I've waited an hour, and the change never happens. If you leave the iPhone app, then return, it updates as it should. It appears that iCloud's silent notification is to being received by the iPhone. Anyone else having the issue? Is there something new with iOS 26.4 that needs to be adjusted to get this to work? Again, works flawlessly with the Mac, just not with the iPhone.

System-wide deadlock in removexattr from revisiond / APFS We're experiencing a deadlock on certains systems when our software is installed, which is causing side effects in our process (and likely others) such as blocked queues and increased memory usage.

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!!

I have a FetchDescriptor that uses starts(with:) which works fine in debug builds but crashes in TestFlight and archive. For background information I'm using iCloud and model inheritance where the property being used in fetch descriptor is defined on the superclass, the fetch descriptor is for the subclass. Implementation: static func fetchDescriptor(nameStartingWith prefix: String) -> FetchDescriptor<ColorAsset> { let predicate = #Predicate<ColorAsset> { asset in asset.name.starts(with: prefix) } return FetchDescriptor<ColorAsset>(predicate: predicate) } @Model public class Asset: Identifiable { // MARK: - Properties var name: String = "" .... } @available(macOS 26.0, *) @Model public class ColorAsset: Asset { ... }

Are there some requirements to use Notification Content Extensions other than including the target to my iOS app? I have done it, configured it to match a certain category of notifications, but my custom interface doesn’t show up. is there anything I need to configure on my main app? Is that anything that should be changed there, such as disabking its botifications handling? is there any requirement concerning the payload? I tried to disable time sensitive and content-available notifications, but it didn’t help.

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?

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.

Hello, I have an app that is using iOS 26 Network Framework APIs. It is using QUIC, TLS 1.3 and Bonjour. For TLS I am using a PKCS#12 identity. All works well and as expected if the devices (iPhone with no cellular, iPhone with cellular, and iPad no cellular) are all on the same wifi network. If I turn off my router (ie no more wifi network) and leave on the wifi toggle on the iOS devices - only the non cellular iPhone and iPad are able to discovery and connect to each other. My iPhone with cellular is not able to. By sharing my logs with Cursor AI it was determined that the connection between the two problematic peers (iPad with no cellular and iPhone with cellular) never even makes it to the TLS step because I never see the logs where I print out the certs I compare. I tried doing "builder.requiredInterfaceType(.wifi)" but doing that blocked the two non cellular devices from working. I also tried "builder.prohibitedInterfaceTypes([.cellular])" but that also did not work. Is AWDL on it's way out? Should I focus my energy on Wi-Fi Aware? Regards, Captadoh

Hi there, Starting with iOS 26.2 RC, all my DeviceActivityMonitor.eventDidReachThreshold get activated immediately as I pick up my iPhone for the first time, two nights in a row. Feedback: FB21267341 There's always a chance something odd is happening to my device in particular (although I can't recall making any changes here and the debug logs point to the issue), but just getting this out there ASAP in case others are seeing this (or haven't tried!), and it's critical as this is the RC. DeviceActivityMonitor.eventDidReachThreshold issues also mentioned here: https://developer.apple.com/forums/thread/793747; but I believe they are different and were potentially fixed in iOS 26.1, but it points to this part of the technology having issues and maybe someone from Apple has been tweaking it.

I’m trying to submit the first release of my iOS app together with the app’s first consumable in-app purchases, and I’m stuck in what looks like an App Store Connect state issue. My app was already rejected by App Review because the in-app purchases did not appear inside the app when the reviewer opened the paywall. Current setup: First app release Current app version page: iOS App Version 1.0.2 Current attached build: 5 App has never been released before 4 consumable IAPs: com.glowup.credits.100 com.glowup.credits.500 com.glowup.credits.1000 com.glowup.credits.2500 What I see in App Store Connect: All 4 IAPs show Waiting for Review On the iOS App Version 1.0.2 page, the In-App Purchases and Subscriptions section does not appear at all Because of that, I cannot explicitly select or attach the IAPs from the version page What I’ve already done: Uploaded a new build and attached build 5 to version 1.0.2 Removed my local StoreKit configuration file so the app now uses live App Store / StoreKit only Confirmed RevenueCat is configured correctly and sees the offering/packages RevenueCat logs show the products exist remotely, but StoreKit cannot fetch any live products and returns an “offerings empty / none of the products could be fetched” type error RevenueCat also reports the products are still in WAITING_FOR_REVIEW My questions: If the IAPs already show Waiting for Review, are they automatically linked to the current app submission? Is it expected that the In-App Purchases and Subscriptions section can disappear from the app version page in this state? For a first-release app that was already rejected, is attaching a new build and clicking Update Review enough, or is there another step required to associate the IAPs with the resubmission? Has anyone seen App Review reject an app for missing IAPs while the IAPs were still pending review and not yet fetchable from StoreKit? Any guidance from someone who has dealt with this exact first-release + first-IAP submission flow would help a lot.

I am working on a large-scale e-commerce application and we are trying to solve a specific issue regarding push notifications and user experience. We have a use case where we need to send a standard push notification to the user, but under certain local conditions on the device, we want to intercept that notification via a Notification Service Extension and suppress/drop it so it does not alert the user. We understand that the com.apple.developer.usernotifications.filtering entitlement allows a Notification Service Extension to drop notifications. However, looking at the entitlement request form, the categories seem strictly limited to: End-to-end encrypted messaging Earthquake warnings Education/learning platforms Enterprise healthcare apps My questions for the community and Apple staff: Is it possible for an e-commerce or retail app to be approved for this entitlement if we have a highly specific, valid use case that improves user experience. If this entitlement is strictly off-limits for our domain, what is the Apple-recommended architecture to achieve this? Thank you in advance for any insights or guidance!

Hi everyone, I’m currently reviewing the app transfer criteria in Apple’s official documentation and came across the following statement: “Mac apps that have used the sandbox environment and share the Application Group Container Directory with other Mac apps can't be transferred.” We are planning to add Widget support to our iOS app before initiating an app transfer. As part of this, the app would likely: Enable App Sandbox Use App Groups to share data between the main app and the Widget Given this, I have a couple of questions: Although the documentation explicitly mentions Mac apps, would the same restriction for app transfer apply to iOS apps that use App Groups (e.g., for Widgets)? If iOS apps are not subject to this restriction, will the Widget extension and its associated App Group data transfer correctly along with the main app during the transfer process? We want to make sure we don’t introduce any blockers before proceeding with the transfer. Any clarification or related experience would be greatly appreciated. Thanks in advance!
