Crash in NetConnection::dequeue When Spawning URLSessionTasks in Loop
I'm encountering a null pointer dereference crash pointing to the internals of CFNetwork library code on iOS. I'm spawning URLSessionTasks at a decently fast rate (~1-5 per second), with the goal being to generate application layer network traffic. I can reliably encounter this crash pointing to NetConnection::dequeue right after a new task has been spawned and had the resume method called. I suspect that this is perhaps a race condition or some delegate/session object lifecycle bug. The crash appears to be more easily reproduced with a higher rate of spawning URLSessionTasks. I've included the JSON crash file, the lldb stack trace, and the source code of my URLSession(Task) usage. urlsession_stuff_stacktrace.txt urlsession_stuff_source.txt urlsession_crash_report.txt

Reply to HealthKit Background Health Data Collection, Emergency Contacts, and Automated Alerting Feasibility
An iOS app can't continuously run in the background. For more information about iOS background execution limits, see here. For using HealthKit in background, see here. (The latter is about HealthKit in watchOS, but the situation is pretty much the same in iOS.) Emergency Contacts is a user feature. For privacy reason, there is no API to access the information. Given that the answer to your question 1 and 2 is no, you can't achieve the automated alerting either. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Developer Program payment never processed, support does not reply
Hi everyone, I am an iOS developer from Ecuador and I am writing to ask if there's any way to fix my issue. After some initial struggling with my phone number not being able to receive Apple verification messages, I was able to register an Apple ID and use that Apple ID to enroll into the Apple Developer Program. Currently, I am stuck at the step of paying the subscription fee. When I try to pay for the 99$ enrollment fee, I receive an Order Acknowledgement e-mail from Apple but the payment is never processed. I have tried with multiple debit cards: 2 times with my main crypto debit card emitted from a Hong Kong bank 1 time with a debit card emitted from a local Ecuadorian bank 1 time with a debit card emitted from a US bank In all these cases the result is the same: the same order acknowledgement e-mail but nothing more happens. I even tried asking the support via e-mail (the only method that is supported in my country), but no one replies. Does anyone have any tip on how to overcome this situation?

Clipboard Bug within simulator 26.4
After updating to Xcode 26.4 and also the update on the simulator the copy paste feature in the simulators doesn't work anymore and i can't build my app without it because the user has to copy and paste api keys in it. Is there an solution for it I have tried to install an other simulator ios version but then the simulator doesn't work on the the new xcode. Have someone already found an solution?

Increased crash occurrence in iOS 26.4
Hello. Our application performs encoding and decoding of large json files which sometimes may take up to 1,5GB of RAM memory. We understand that this may be a problem for devices with low RAM memory (3GB). But before iOS 26.4 we didn't have much occurrences (3 for the last 90 days). Starting from iOS 26.4 it started to crash a lot. Can the reason be that iOS 26.4 occupies more RAM memory so there is less memory left for our app? Or maybe starting from iOS 26.4 there is less RAM memory allocated per app? The crash message is Fatal error: failed to allocate 392 bytes of memory with alignment 8

Reply to TKTokenDriverConfiguration becomes permanently unusable after ctkd process restart
[quote='882312022, dopey, /thread/820940?answerId=882312022#882312022, /profile/dopey'] We are actually seeing seeing this happen in practice. [/quote] OK.

It’s hard to say what’s going on without more logging, but the most likely cause is a memory pressure exit, and that’s very non-deterministic. [quote='882312022, dopey, /thread/820940?answerId=882312022#882312022, /profile/dopey'] I will open a bug and post the bug number. [/quote] Much appreciated. Ideally this would include a sysdiagnose log taken: On a device with extra CryptoTokenKit logging enabled (see below) Shortly after seeing the problem But that might be hard to get, so you should feel free to file a bug with only your ‘kill ctkd’ step as evidence. On the logging front, our Bug Reporting > Profiles and Logs only has a CryptoTokenKit profile for iOS. However, you can install that profile on macOS, and I think

AccessoryTransport Extensions not launching on iOS 26.5 beta — missing entitlements not available in provisioning
Environment Xcode 26.5 beta iOS 26.5 beta Using AccessorySetupKit + AccessoryTransportExtension framework Three extensions: AccessoryTransportAppExtension, AccessoryTransportSecurityExtension, AccessoryDataProviderExtension Background Everything worked correctly on iOS 26.4 beta. All three extensions shared the entitlement com.apple.developer.accessory-transport-extension, and the system launched them as expected. After upgrading to iOS 26.5 beta (both Xcode and device), the app compiles and runs, the accessory pairs and connects successfully (state = authorized, BLE connected, notification forwarding = allow), but none of the extensions are launched by the system. Investigation Captured system Console logs from the device and found these errors from deviceaccessd: error deviceaccessd ### Extension 'com.huami.NotificationForwardingDemo.AccessoryDataProviderExtension' is missing entitlement: com.apple.developer.accessory-data-provider for com.apple.accessory-data-provider error devic

I tested Xcode 26.5 beta 1 (build 17F5012f), released on 2026-03-30, and the issue remains unchanged: app-hosted unit tests still fail on the same physical iOS 16 device with Logic Testing Unavailable.
