It has been approximately three weeks since we submitted our app for review via App Store Connect, but it remains "In Review" and the review process has not been completed. For this reason, we also requested an expedited app review to the App Review Team last week. Will the review proceed if we simply wait? Is there any way to check the detailed status of this app review?

Dear Sir/Madam, Thank you for your support. I have reviewed the documentation for Local Push Connectivity (see URL below) and, following the instruction in the "Important" section to "Request this entitlement from the Entitlement Request Page," I completed the application process for this Entitlement on March 11, 2026. [Local push connectivity] https://developer.apple.com/documentation/networkextension/local-push-connectivity?language=objc#Supporting-APNs-and-local-push-connectivity-in-one-app Subsequently, on March 13, 2026, I received the following reply from Apple: Sub : Re: Requesting Network Extension App Push Entitlement From: Local Push Review Sent: Friday, March 13, 2026 4:09 AM Hi, Thank you for your interest in the Local Push Connectivity entitlement. Your entitlement request has been approved for: Team ID: NWKYYYYYYY Technical documentation on this API is available here: -(Omission) - Best Regards, Apple Developer Relations My understanding is that upon approval of this application, an "Entitlements" field should be added to the input fields for creating provisioning profiles. However, as of today(March 18, 2026), it has not yet been added. Will the Entitlements field be added if I simply wait? My account (Apple ID), which submitted the application, belongs to three Team IDs. For convenience, I will refer to them as Team ID SV3XXXXXXX, Team ID NWKYYYYYYY, and Team ID WEJZZZZZZZ. The application status for Entitlements for each Team ID is as follows: Team ID SV3XXXXXXX Entitlements: Present. Applied for Entitlements on February 6, 2021. (Received "Re: Requesting Network Extension App Push Entitlement" email on February 6, 2021) Team ID NWKYYYYYYY Entitlements: Not present. Applied for Entitlements on March 13, 2026. (Received "Re: Requesting Network Extension App Push Entitlement" email on March 13, 2026) Team ID WEJZZZZZZZ Entitlements: Present. No record (email) of applying for Entitlements. Because of this, I am concerned that the Entitlements applied for Team ID NWKYYYYYYY may have been mistakenly granted to Team ID WEJZZZZZZZ, and I am inquiring about this. Will the Entitlements field for Team ID NWKYYYYYYY be added if I simply wait? Thank you in advance.

I am developing an application that uses NetworkExtension (Local PUSH function) And VoIP(APNs) PUSH. Nowadays, I found a problem on this app doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an APNs PUSH. My confimation result of my app and server log is below. 11:00 AM: my server(PBX) requests a VoIP(APNs) PUSH notification to the APNs. But my app does not receive the VoIP(APNs) PUSH. At this time, my app is running on LAN (Wi-Fi without internet connection), as a result, NetworkExtension was running. so I think this is normal behaviour. 14:55:11 PM: There is an incoming call from the my server(PBX) via local net, and NetworkExtension calls iOS API(API name is reportIncomingCall). However, iOS does not call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall. 14:55:11 PM: At almost the same time, iOS calls the delegate cdidReceiveIncomingPushWithPayload of VoIP PUSH. (instead of call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall?) And the content of this VoIP(APNs) PUSH was the incoming call at "11:00 AM". In other words, the VoIP(APNs) PUSH at 11:00 AM is stuck inside iOS, and at 14:55:11 PM, from NetworkExtension reports it. I feel there is a problem on iOS doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an VoIP(APNs) PUSH. Would you tell me Apple's opioion about this? If this is known problem, Please tell me about it.

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.

Hello, I am developing an internal phone application using CallKit. I am experiencing an issue with the behavior of remoteHandle settings in iOS 26 and would appreciate any insights you can provide towards a solution. 1. Problem Description When an iPhone running iOS 26 is in a sleep state and receives a VoIP incoming call where remoteHandle is set to nil or an empty string (@""), we are unable to transition to our application (the UIExtension provided by the provider) from the CallKit UI's "More" (…) button after answering the call. 2. Conditions and Symptoms OS Version: iOS 26 Initial State: iPhone is in a sleep state Call Type: An unsolicited(unknown number) VoIP incoming call where the CXCallUpdate's remoteHandle is set to either nil or [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""] Symptoms: After answering the VoIP call by sliding the button, selecting the "More" (…) button displayed on the CallKit screen does not launch our application's UIExtension (custom UI), and the iPhone instead stay to the CallKit screen. 3. Previous Behavior (Up to iOS 18) Up to iOS 18, even when remoteHandle was set to an empty string using the following code, the application would transition normally from "More" after answering an incoming call from a sleep state. CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""]; [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 4. Unsuccessful Attempts to Resolve The issue remained unresolved after changing the handling for unsolicited(unknown number) incoming calls as follows: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = nil; // Set remoteHandle to nil [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 5. Workaround (Temporary) The problem can be resolved, and the application can transition successfully, by setting a dummy numerical value (e.g., "0") for the value in remoteHandle using the following code: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@"0"]; // Set a dummy numerical value [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 6. Additional Information If remoteHandle is correctly set with the caller's number (i.e., not an unsolicited(unknown number) call; e.g., value:@"1234567890"), the application transitions normally from the "More" button after answering an incoming call from a sleep state, even in iOS 26. The above issue does not occur when answering incoming calls while the iPhone is in an active state (not sleeping). 7. Questions Have there been any other reports of similar behavior? Should this be considered a bug in CallKit for iOS 26? Should I make file a new Feedback report? Is there a suitable method to resolve this issue when the caller ID is unsolicited (nil or an empty string)? This problem significantly impacts user operations as end-users are unable to perform essential in-app actions such as hold or transfer after answering an unsolicited(unknown number) call from a sleep state. We are eager to find an urgent solution and would appreciate any information or advice you can provide. Thank you for your assistance.

My iPhone VoIP app, which I'm developing, uses Apple Push Notification service (APNs). I have a question regarding the following statement found in "[Overview of app transfer > Apps using push notifications]" Overview of app transfer You must manually reestablish push notification services if transferring an app that uses the Apple Push Notifications service (APNs). The recipient must create a new client SSL certificate using their developer account, as associated client SSL certificates, TLS certificates, and authentication tokens aren’t transferred. Question Let's say the recipient of the app transfer creates a "new SSL certificates, TLS certificates, and authentication tokens." Afterward, we need to verify that the Apple Push Notification service (APNs) works correctly when combining the transferred app with this "new SSL certificates, TLS certificates, and authentication tokens." However, until the recipient finishes verifying that it works correctly, the transferor want to keep the app available for download as before and be able to use the Apple Push Notification service. Is this possible? More specifically, can the recipient test the app to be transferred on TestFlight "before the transfer is completed"? I want to combine it with the "new SSL certificates, TLS certificates, and authentication tokens." and test it on TestFlight. Reading "[Initiate an app transfer]," it mentions the existence of a "Pending App Transfer" status. During this "Pending App Transfer" status, can the recipient test the app on TestFlight? Initiate an app transfer After you initiate the transfer, the app stays in its previous status, with the Pending App Transfer status added, until the recipient accepts it or the transfer expires after 60 days. Also, if there are any documents describing these procedures, I would appreciate it if you could share them. Thank you very much.

We are encountering the following issue with our VoIP application for iPhone, published on the App Store, and would appreciate your guidance on possible countermeasures. The VoIP application (callee side) utilizes a Wi-Fi network. The sequence leading to the issue is as follows: VoIP App (callee): Launches iPhone (callee): Locks (e.g., by short-pressing the power button) VoIP App (callee): Transitions to a suspended state VoIP App (caller): Initiates a VoIP call VoIP App (callee): Receives a local push notification VoIP App (callee): Answers the incoming call VoIP App (callee): Executes performAnswerCallAction() After this, the VoIP App (callee) uses "NSTimer scheduledTimerWithTimeInterval" to manage internal processing timing. However, the processing sometimes takes longer than the specified waiting time. Specifically, delays of several seconds can occur. We understood that if the user is interacting with the screen and both the iPhone and the VoIP app are in an active state, the VoIP app's processing would not be delayed. However, can significant delays (several seconds) in application processing still occur even when the iPhone is in an active state (i.e., the user is interacting with the screen)?"

(of course The VoIP app itself does not close the sockets in this timing) Given that the user has performed an answer operation, the iPhone is in an active state, and the VoIP app is running, what could be the possible reasons why the sockets suddenly become unusable? Could you please provide guidance on how to avoid such socket closures? Our VoIP app uses SCNetworkReachabilitySetCallback to receive network change notifications, but no notifications regarding network changes were received at the time errno = 57 occurred. Is it possible for sockets used by an application to be closed without any notification to the application itself?

I investigated what network interface names are assigned to carrier networks on a dual SIM iPhone by examining the output of getifaddrs(). (An part of the program used for this is provided below.) ////////////// struct ifaddrs *interfaces = NULL; struct ifaddrs *an_interface = NULL; if (0 == getifaddrs(&interfaces)) { an_interface = interfaces; while (an_interface != NULL) { if( an_interface->ifa_addr->sa_family == AF_INET) { NSString* name = [NSString stringWithUTF8String:an_interface->ifa_name]; NSLog(@"Interface name is: %@", name); } an_interface = an_interface->ifa_next; } } freeifaddrs(interfaces); In this investigation, it appeared that the interface name for the sXGP SIM selected under "iPhone > Settings > Cellular > Cellular Data" was always "pdp_ip0". (A screenshot of "Cellular Data" is provided below. this is sample of sXGP selected )" [QUESTION] Is the SIM selected in Settings of iPhone always assigned to "pdp_ip0"? [BACKGROUND] I am developing a VoIP application and opening sockets by specifying IP addresses for communication. On a dual SIM iPhone, multiple networks (IP addresses) are visible. Therefore, I need to determine which network to use. My question is whether I can reliably make this decision based on the network interface name. If the SIM selected in Settings is always assigned to "pdp_ip0", I intend to open the socket using the IP address of "pdp_ip0". Alternatively, should I use a different method to select the appropriate network interface?

We are currently developing a VoIP application that supports Local Push extention. We discovered an issue with this app where the performEndCallAction response to reportCallWithUUID is occasionally slow.(See below for detail) It usually works without any issues, so we believe there is no problem with the app's processing flow. This issue only occurs very rarely, but each time it does there is a delay of about 60 seconds, which leads us to suspect that there is some kind of problem on the iOS side, and that fail-safe processing is occurring after 60 seconds. Do you know of a workaround for this issue?

I am developing a VoIP application that uses NetworkExtension (Local PUSH function) And VoIP(APNs) PUSH. Since iPhone X, iPhones have supported eSIM, allowing for the simultaneous use of a physical SIM and an eSIM. Consequently, users of our VoIP app have requested the ability to lock the network used by the VoIP app to either the eSIM or the physical SIM. Our VoIP app utilizes the network through the socket API. Is there an API in the iOS SDK to lock the network used via sockets to either the eSIM or the physical SIM? In other words, we would like to be able to retrieve the IP address assigned to the eSIM or the physical SIM in advance, and know which IP address is assigned to which SIM. Are there any such APIs available (that are not "Deprecated")

We are currently developing a VoIP application that supports Local Push extention. I would like to ask for your advice on how the extension works when the iPhone goes into sleep mode. Our App are using GCD (Grand Central Dispatch) to perform periodic processing within the extension, creating a cycle by it. [sample of an our source] class LocalPushProvider: NEAppPushProvider { let activeQueue: DispatchQueue = DispatchQueue(label: "com.myapp.LocalPushProvider.ActiveQueue", autoreleaseFrequency: .workItem) var activeSchecule: Cancellable? override func start(completionHandler: @escaping (Error?) -> Void) { : self.activeSchecule = self.activeQueue.schedule( after: .init(.now() + .seconds(10)), // start schedule after 10sec interval: .seconds(10) // interval 10sec ) { self.activeTimerProc() } completionHandler(nil) } } However In this App that we are confirming that when the iPhone goes into sleep mode, self.activeTimerProc() is not called at 10-second intervals, but is significantly delayed (approximately 30 to 180 seconds). What factors could be causing the timer processing using GCD not to be executed at the specified interval when the iPhone is in sleep mode? Also, please let us know if there are any implementation errors or points to note. I apologize for bothering you during your busy schedule, but I would appreciate your response.

I am developing a VoIP phone application(Our Phoneapp) using APNs VoIP push. I have a question regarding a behavior I discovered during testing of this application. When performing the following operations using an iPhoneSE3 with an sXGP-NW SIM inserted, 0xBAADCA11 occurs upon receiving an APNs VoIP PUSH. Do you have any information regarding this issue? 0xBAADCA11 occurs in operation 8. However, since there were no problems in operation 4 (the app works when Wi-Fi is off), I think there is no issue with the Our Phoneapp. [Configuration of system components] [VoIP Telephone] --Call to iPhone(Phoneapp)--> [Our VoIP PBX Server] -- VoIP PUSH request --> [Apple APNs Server] -- VoIP PUSH --> [Our Phoneapp (iPhoneSE3(with sXGP SIM)] [Operations] (The issue is reproducible 100% by following oparation) iPhoneSE3: Power on (iPhoneSE3 with sXGP SIM) iPhoneSE3: Wi-Fi off, connect to the internet via SIM. VoIP Telephone: Call to Our Phoneapp iPhoneSE3: Receives VoIP PUSH and Phoneapp launches. Successfully answers the call and communication is possible. (Receives VoIP push notification from APNs via sXGP SIM) iPhoneSE3: Wi-Fi is turned ON, connect to the internet via Wi-Fi. iPhoneSE3: Task kill Our Phoneapp. VoIP Telephone: Call to Our Phoneapp iPhoneSE3: iOS does not call the push notification delegate (didReceiveIncomingPushWithPayload). As a result our Phoneapp is unable to detect the incoming call, However, an ips log with 0xBAADCA11 is output. in other words, iOS received the VoIP PUSH, but Our Phoneapp dose not call CallKit, so Our Phoneapp was terminated by iOS.

I am developing "local push" VoIP application. I have a question about issues I found while testing this app. After repeating a test for 24 hours in which a incoming call followed by an immediate disconnect 0.1 seconds later, the iPhone of incommig call side encountered a 0xBAADCA11 error, causing iOS to force-close the app. (The incidence is low, occurring three times in 17280 times incoming call(24 hours.)) This problem found on iOS17.6.1 (iPhone11Pro). When the same test was performed on iOS18.2 (iPhoneSE3), the problem did not occur. Did iOS take something measures against the 0xBAADCA11 error between iOS17.6.1 and iOS18.2? If yes, I want to encourage customers to upgrade to the latest iOS version, please tell me about it? ※I have attached an ips files and sysdiagnose file of the 0xBAADCA11 error occurring. (please refer sysdiagnose also if you need.)

I tried below at 2:00 PM on 21/01/2025(JST). Apple Push Notification service server certificate update I followed above, a new server certificate: "SHA-2 Root : USERTrust RSA Certification Authority certificate" was added to my push server, but a certificate error occurred and push notifications could not be sent. So I refered this article,Instead of connecting via DNS name resolution at api.development.push.apple.com, I fixed api.development.push.apple.com to "17.188.143.34" in /etc/hosts, I could push notifications with the new server certificate. (I got this IP(17.188.143.34) from this airtcle) From this, I suspect that Apple had not yet updated the APNs certificate (CA) for the Sandbox environment as of 2:00 PM on January 21, 2025 (JST). Was the update published as scheduled?
