Sandbox Testing Issue: 'Submit for Review' Button Missing for Subscription IAPSubmit
Hello Developers! I am trying to run a test In-App Purchase (IAP) for a renewable subscription product in the sandbox environment. I have set up everything required for sandbox testing, but it’s unclear whether the subscription product needs to be pre-approved by Apple for testing. If approval is required, I have already added the necessary metadata, but the status still shows "Ready for Submit." Additionally, when I save the page, a "Submit for Review" button briefly appears for a fraction of a second on the subscription page before disappearing. Is this button missing, or is there a known issue with this process? This is my first time running this test, and I would appreciate any pointers or suggestions. Thanks!

Custom IPSec IKEv2 with Packet Tunnel Provider Extension on iOS
We’re looking to implement a custom IPSec IKEv2 VPN using the Packet Tunnel Provider network extension on iOS because we need to add extra information to EAP, which the built-in IKEv2 VPN configuration does not support. Is it possible to handle the full IKEv2 negotiation and IPSec tunneling within the Packet Tunnel Provider extension? Or are there limitations that would prevent implementing a full IKEv2 stack this way? Any insights or alternative approaches would be appreciated. Thanks!

The host app appears in Accessibility Permission
I'm learning XPC by inspecting the GitHub Copilot project. I figured out that the schema works as follows: The host app with a UI to manage settings A Service Extension that controls the Xcode Editor A communication bridge cli app that connects the first two As far as I understand an app appears in the Accessibility Permission when it calls the next method: let key = kAXTrustedCheckOptionPrompt.takeRetainedValue() as NSString AXIsProcessTrustedWithOptions([key: true] as CFDictionary) This method is only called by the Service Extension. However, when I run a release build from the /Application folder (where launch agents point to), there are two records appearing in the Accessibility Permission list: The host app The needed Service Extension I compared all metadata files from Copilot with my copy line-by-line, but still can't figure out why the host app record appears in the Accessibility Permission, since the host app does not call the AXIsProcessTrustedWithOptions() method at all. Could you give me any clue to help me wrap my head around it?

Can we create a bundled non-interactive macOS application which uses CFRunLoop only(instead of using NSApplicationMain to run NSRunLoop)?
I am developing a macOS non-interactive macOS application which does not show any ui. i want to block main thread and do all the work on worker thread . Once done with work in worker thread, want to unblock main thread by exiting event loop to terminate application. Because i dont want to show any UI or use any Foundation/Cocoa functionality, i am thinking of using CFRunLoop to block main thread from exiting until i finish my work in worker thread. When i tried this in a project, I am able to finish work in worker thread after block main thread using CFRunLoop. I also want this application to be a bundled application, which can be launched by double clicking on application bundle . But when i tried it in my xcode project by launching it using double clicking on application bundle, application keeps on toggling/bouncing in the dock menu with a status "Not responding". Although i am able to complete my work in worker thread. import Foundation let runLoop = CFRunLoopGetCurrent() func workerTask() { DispatchQueue.global().async { print("do its work") sleep(5) // do some work print("calling exit event loop") CFRunLoopStop(runLoop) print ("unblocking main thread") } } workerTask () // blocking main thread print ("blocked main thread") CFRunLoopRun() print ("exit") Why i am getting this application bouncing in doc menu behavior ? I tried by using NSApplicationMain instead of CFRunLoop in my project, in that case i didnt get this behavior . Does NSApplicationMain does some extra work before starting NSRunLoop which i am not doing while using CFRunLoop, which is showing this toggling/Bouncing application icon in Dock menu ? or Is this bouncing app icon issue is related to run loop i am using which is CFRunLoop ? Note : If i dont use a bundled application and use a commandline application then i am able to do all steps in worker thread and exit main thread as i wanted after finishing my work . But i need to do all this in application which can be launched using double clicking (bundled applcation). If not by using CFRunLoop, then how can i achive this ? - Create a application which shows no UI and do all work in worker thread while main thread is blocked. Once work is done unblock main thread and exit. And user should be able to launch application using double click the application icon.

CoreBluetooth and Swift strict concurrency checking
As of iOS 18.3 SDK, Core Bluetooth is still mostly an Objective-C framework: key objects like CBPeripheral inherit from NSObjectProtocol and does not conform to Sendable. CBCentralManager has a convenience initializer that allows the caller to provide a dispatch_queue for delegate callbacks. I want my Swift package that implements Core Bluetooth to conform to Swift 6 strict concurrency checking. It is unsafe to dispatch the delegate events onto my own actor, as the passed in objects are presumably not thread-safe. What is the recommended concurrency safe way to implement Core Bluetooth in Swift 6 with strict concurrency checking enabled?

Inconsistent BLE Extended Advertising Scanning on iOS
I'm developing an iOS 18 app using Core Bluetooth on an iPhone 16 Pro to scan for BLE Extended Advertising packets. However, scanning behavior is inconsistent. Sometimes, the app detects extended advertising packets correctly, but other times, it fails to find them even when the advertiser is active. I tested using nRF Connect on both my iPhone 16 Pro and another Android device that I'm also developing an app for. The Android device consistently detects the extended advertising packets, but my iPhone 16 Pro has inconsistent results. Legacy advertising packets are scanned without any issues. The same peripheral is consistently detected on Android and other BLE scanners. I've tested with different scan settings, restarted Bluetooth, and rebooted the device, but the issue persists. Does iOS 18 have any known limitations with BLE Extended Advertising? Any workarounds to improve scanning reliability?

Push Live Activity not showing up
This is in an iOS Simulator running iOS 18.2 I send a start live activity push notification from the Push Notifications Console on icloud.developer.apple.com. When checking the console.log output it seems to receive the message, yet the activity does not appear in the dynamic island. (the app is backgrounded when I test this) Can anyone tell me why it's not showing? Starting the same activity from within the app using Swift code works fine. Here is the console.app output: default 11:01:59.060954+0100 apsd <APSConnectionServer: 0x104207b80; development/com.apple.aps.sessioncore.PushNotifications.dev/liveactivitiesd 0>: Sending push to client.

SetFocusFilterIntent `perform()` method is not called on iOS 18 beta
I’ve set up a focus filter, but the perform() method in SetFocusFilterIntent isn't called when the focus mode is toggled on or off on my iPhone since I updated to iOS 18 beta (22A5326f). I can reproduce the issue for my app, but focus filters are also broken for any third-party apps installed on my phone, so I guess it's not specific to how I've implemented my filter intent. This used to work perfectly on iOS 17. I didn't change a single line of code, and it broke completely on the latest iOS 18 beta. I've filed a bug report including a sysdiagnose (FB14715113). To the developers out there, is this something you are also observing in your apps?

Old developer account still receiving payments after migration
Hi, I've migrated my app to another developer account more than half a year ago, but I'm still receiving a few transaction payments in the old developer account, which currently has no app. The payment date shown in the report is last month. I'm wondering how could this happen. Is it possible for users to initiate a transaction half a year ago and only successfully pay it now?

What is the point of thread-id/grouping in push notifications if grouping depends upon user preferences?
There's plenty of articles out there about programatically grouping push notifications. However I have tried setting the thread-id in the push payload when sending a push, or setting the threadIdentifier for a received push in a notification service extension to be the same for several pushes. But if within the iPhone Settings / Notifications the user selects to display pushes as List and turns off Notification Grouping, then each notification resulting from the push appears on its own separately. Is there something other than thread-id/threadidentifier that is used to programmatically group them? If not then whats the point of these as grouping and display is actually under the control of user.

DNS duration 4294893875545978
When I use NSURLSessionTaskTransactionMetrics property domainLookupStartDate and domainLookupEndDate to calculate the duration of DNS, sometimes I get 4294893875545978 or -4294893875545978 return method like this [NSNumber numberWithLongLong:[taskMetrics.domainLookupEndDate timeIntervalSinceDate:taskMetrics.domainLookupStartDate?]*1000000000] The hexadecimal value of 4294893875545978 is 0xF3F3F3F3F3F3A. Is 4294893875545978 a special value?

CNContact poster
Hi all, From what I’ve seen on forums and other sources, it appears that nothing can be done to set the contact poster programmatically. Setting the imageData property affects only the thumbnail image. Does anyone know if this is explicitly documented somewhere? I need this information for a POC document. I watched the iOS 17 keynote (where it was introduced), the Platform State of Union, and other WWDC videos, but I couldn’t find any mention of it. The Contacts framework documentation only explains what can be retrieved from this property and doesn’t mention any way to set the contact poster. If anyone has any information on this, please help! Thanks in advance!

SwiftData and async functions
Hello, I recently published an app that uses Swift Data as its primary data storage. The app uses concurrency, background threads, async await, and BLE communication. Sadly, I see my app incurs many fringe crashes, involving EXC_BAD_ACCESS, KERN_INVALID_ADDRESS, EXC_BREAKPOINT, etc. I followed these guidelines: One ModelContainer that is stored as a global variable and used throughout. ModelContexts are created separately for each task, changes are saved manually, and models are not passed around. Threads with different ModelContexts might manipulate and/or read the same data simultaneously. I was under the impression this meets the usage requirements. I suspect perhaps the issue lies in my usage of contexts in a single await function, that might be paused and resumed on a different thread (although same execution path). Is that the case? If so, how should SwiftData be used in async scopes? Is there anything else particularly wrong in my approach?

Notification Delivery Issues for Location Push Service Extension
We are currently testing the implementation of our Location Push Service Extension (LPSE) in both Ad Hoc and Release environments. We have encountered an issue where LPSE notifications, which were previously working correctly, suddenly fail to be delivered on some devices. After a period of several hours, the notifications resume arriving, but the issue remains intermittent. Notably, during these periods of suspected delivery restriction, regular push notifications (e.g., those using apns-push-type: alert) are delivered and displayed without any problem. [Detailed Situation] Test Environment and Scope We are testing LPSE after obtaining the necessary entitlements, in both Ad Hoc and Release environments. The issue is not observed on all test devices; only certain devices are affected. Observed Behavior Under normal circumstances, LPSE notifications are received and the extension is activated; however, on some devices the notifications suddenly stop arriving. During these periods, even when sending notifications with apns-push-type: location directly via the CloudKit Push Notification Console, no response is observed on the affected devices. The APNs server (api.push.apple.com) always returns a 200 OK response via HTTP/2, and our server-side logs and configurations (DNS resolution performed on every request, using the same JWT token for 59 minutes per session, communication via HTTP/2 with ALPN Protocol: h2) show no issues. Other app functionalities (network communication, UI responsiveness, etc.) work normally. Sending content When sending notifications from our server to APNs (api.push.apple.com), we use the following configuration (over HTTP/2): const payload = { aps: { 'content-available': 1 } }; const headers = { ':method': 'POST', ':path': /3/device/${apnsToken}, 'Authorization': bearer ${jwtToken}, 'apns-topic': 'ot.Here.location-query', 'apns-priority': '10', 'apns-push-type': 'location', 'Content-Type': 'application/json' }; We perform DNS resolution for every request, use the same JWT token for a 59-minute period per session, and communicate via HTTP/2 with ALPN Protocol: h2. Hypothesis on the Cause We suspect that due to an implementation issue, silent push notifications (using content-available: 1) were being sent every few minutes concurrently, which may have triggered an APNs delivery restriction (rate limiting). As a countermeasure, we have completely stopped sending silent pushes and any other background notifications aside from LPSE; however, the issue persists. Additionally, even after resetting affected devices, the delivery problem continues to occur. [Questions for Diagnosis] Given the above situation, is it reasonable to suspect that excessive silent push notifications have triggered an APNs delivery restriction? Does such a silent push restriction affect LPSE notifications (i.e., those sent with apns-push-type: location)? Do APNs delivery restrictions persist even after a device has been reset? Can a high volume of LPSE notifications alone (without silent pushes) also trigger a delivery restriction? → This is our primary concern since it poses a significant implementation challenge. Please let us know if any additional information is required for diagnosis.

Bluetooth
你好,有个问题想请教一下: 我们的app是一款与CGM实时血糖相关的app,app支持在后台通过蓝牙跟CGM血糖设备保持连接。 现在遇到一个问题: 首先,app在后台运行期间,蓝牙是开启状态的,跟CGM设备也是连接的状态。 某个时刻,监听到蓝牙的状态突然从 poweredOn 变为了 resetting ,然后蓝牙又恢复了,状态变为了 poweredOn 这时候,问题出现了:之前连接的那个CGM血糖设备一直无法扫描到了!! 我想问一下: 什么情况下,蓝牙状态会变为resetting 蓝牙状态恢复为poweredOn后,之前连接的那个CGM血糖设备一直无法扫描到了,为什么?我要怎么做才能恢复,重新扫描到之前连接的这个设备?

Gathering Required Information for Troubleshooting Wallet Issues
Hi, To ensure the issue is not caused by an error within your app or web service request, please review the following documentation: Wallet Passes Wallet Developer Guide If the resources above don’t help identify the cause of the error, please provide more information about your app or web services to get started. To prevent sending sensitive credentials in plain text, create a report in Feedback Assistant to share the details requested below. Additionally, if the error is something we need to investigate further, the appropriate engineering teams also have access to the same information and can communicate with you directly within Feedback Assistant for more information, as needed. Please follow the instructions below to submit your report. For issues occurring with your native app or web service, perform the following steps: Install the Wallet profile on your iOS or watchOS device. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS or watchOS device. Create a Feedback Assistant report with the following information: The serial number of the device. Open Settings > General > About > Serial Number (tap and hold to copy). The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string. Open Settings > General > About > SEID (tap and hold to copy). The sysdiagnose gathered after reproducing the issue. The .pkpass file(s), pass signing certificate(s) and pass type identiifier(s) (optional). The timestamp of when the issue was reproduced. Screenshots or videos of errors and unexpected behaviors (optional). Important: From the logs gathered above, you should be able to determine the cause of the failure from PassbookUIService, PassKit or PassKitCore, and by filtering for your SEID or pass type identifier in the Safari Web Inspector. See Inspecting Safari on macOS to learn more. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Wallet pass implementation. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your web implementation, a configuration issue within your developer account, or an underlying system bug. Cheers, Paris X Pinkney |  WWDR | DTS Engineer
