“Visual Studio Maui IOS”

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 ou

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.

Hi team: I recently update to Xcode 26.4, and I encountered crash when running to < iOS 26.4 both for physical device and Simulator with this log: dyld[1257]: Symbol not found: _$s9MetricKit10mxSignpost_3dso3log4name10signpostID__ySo03os_H7_type_ta_SVSo03OS_j1_F0Cs12StaticStringV0J0010OSSignpostI0VALSays7CVarArg_pGtF Referenced from: <164CCEB0-E1F8-3CE2-A934-2096C19C0A9A> /private/var/containers/Bundle/Application/EA709A68-F76F-4D97-85C6-B71D61D68389/xxx.app/xxx.debug.dylib Expected in: <9E5EC9BB-5828-329C-A2BC-038B67060298> /System/Library/Frameworks/MetricKit.framework/MetricKit Symbol not found: _$s9MetricKit10mxSignpost_3dso3log4name10signpostID__ySo03os_H7_type_ta_SVSo03OS_j1_F0Cs12StaticStringV0J0010OSSignpostI0VALSays7CVarArg_pGtF Referenced from: <164CCEB0-E1F8-3CE2-A934-2096C19C0A9A>x /private/var/containers/Bundle/Application/EA709A68-F76F-4D97-85C6-B71D61D68389/xxx.app/xxx.debug.dylib Expected in: <9E5EC9BB-5828-329C-A2BC-038B67060298> /System/Library/Frameworks/

I'm experiencing an issue where the App Group shared container appears to be recreated (with a new creation date) during an app update, resulting in complete loss of locally stored data. Background My app uses UserDefaults, Realm, Core Data, and CloudKit, with all local data stored in the App Group container (FileManager.containerURL(forSecurityApplicationGroupIdentifier:)). The app has been available since 2016 and has a stable user base. Starting last year, I began receiving occasional reports from users saying all their data in the app had disappeared. To investigate, I added diagnostic logging that detects when an existing user's data appears to have been reset — specifically by checking the App Group container's file system creation date, and the existence and values of expected files. What the diagnostics revealed When the issue occurs, I observe the following: The App Group container has a recent creation date, far newer than the user's first launch date The Core Data store file's creation date is also

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

We have an application that capture audio and video. App captures audio PCM on internal or external microphone and displays audio level on the screen. App was working fine for many years but after iOS 26.4 upgrade, averagePowerLevel and peakHoldLevel are stuck to -120 values. Any suggestion?

Hi, We're having problems starting an Ad Hoc ipa on an iPad with iOS 12.7.7 and 12.7.8, probably iOS 12 in general. The iPad's UUID is added to the certificate.

We are encountering an issue in an iOS application where functionality works correctly in Debug builds but fails in Release builds distributed via TestFlight. Details Debug (No Optimization -Onone): Works correctly Release (Optimize for Speed -O): Fails Release with -Onone: Works, but app size nearly doubles Context The issue is related to integration with the Microsoft ONNX runtime library. It appears that the Swift/Clang compiler is aggressively optimizing certain parts of the code in Release builds, possibly removing or altering required logic. Observations The issue started appearing with recent iOS/Xcode updates. No code changes affecting this logic were made recently. Behavior strongly suggests optimization-related side effects. Questions Are there known issues with aggressive optimization (-O) affecting third-party libraries? Are there recommended flags to selectively disable optimization for specific modules or functions? Any tools or diagnostics to identify what is being optimized o

Hello All, I have a app which has a WKWebview loading some code from a remote origin - https://my-company.example.com When WKWebview loads remote origin, that page does load some of the sub-resources from in-app localhost server (GCDWebserver), i.e. reach out to a loopback based in-app GCDWebserver, now to provide a secure context I had an existing setup with self signed cert, CORS and everything needed for https on localhost. And the sub-resources used to load fine from https localhost till 26.4 Starting with iOS 26.4 it started breaking with TLSv1_ALERT_UNKNOWN_CA Is there any known guidance for this? Technically as per w3c spec, localhost is considered secure context by default right? and no special things need to be done. But ios/Webkit seem to be different in this regard. Is this a known issue, and is there any mitigation here? I'll try to provide a sample app soon if possible.

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?
