}
Doesn't have any issues on accessing the values but seen the below console error:
Couldn't read values in CFPrefsPlistSource<0x103eedb00> (Domain: group.com.kodiak.InstaPoC, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd
Does it require any action here ?

We're currently migrating from AppDelegate to UISceneDelegate due to console warnings .
Our application's UI, which is built on a single webpage, functions correctly when launched in the foreground after this migration.
However, we've encountered an issue with partial rendered UI components when launching the application from the background, such as upon receiving a VoIP call.
During a background launch, the following delegate calls occur before the client attempts to load a local webpage:
[08/07 16:25:49:037][ 0x101ea3910]<ALA_SIGNAL>: [OS-PLT] Exit -[AppDelegate application:didFinishLaunchingWithOptions:]
[08/07 16:25:49:084][ 0x10c0c4140]<PushToTalk> [Pushnotif] [] <ALA_SIGNAL>: [OS-CCF] Enter -[PushNotificationManager pushRegistry:didReceiveIncomingPushWithPayload:forType:withCompletionHandler:]
[08/07 16:25:49:098][ 0x101ea3910]Begin -[SceneDelegate scene:willConnectToSession:options:]
[08/07 16:25:49:098][ 0x101ea3910]Exit -[SceneDelegate scene:willConnectToSession:options:]
As part of client login process we load the index page in WebKit here:
[08/07 16:25:50:977][ 0x101ea3910]<ALA_SIGNAL>: [PLT-OS] Enter -[SceneDelegate loadUI:] [UI Launch Reason = 1]
Code:
NSString *path = [[NSBundle mainBundle]pathForResource:@"index" ofType:@"html" inDirectory:@"www"];
NSURL *urlReq = [NSURL fileURLWithPath:path];
[webView loadFileURL:urlReq allowingReadAccessToURL:urlReq];
The problem we're observing is that the webpage is only partially rendering in this background launch scenario (Seen after brought to FG).
Any insights or assistance you can provide would be greatly appreciated.
The application is placed into the idle state. Subsequently, the device enters a sleep state.
While the device is in sleep, App start background task within the application successfully receives its expirationHandler callback.
App received the expiration callback and App called the end BGtask
OS did not released the Assertion.
Resulting in App getting terminated by the OS for exceeding the BG task

Applicaiton is built with WebKit and native camera view controller .
Issue is seen always when presenting a UIVideoEditorController class on top of MainVC(webKit).
Please refer the attached image
Code:
self.videoEditor.modalPresentationStyle = UIModalPresentationFullScreen;
[viewController presentViewController:self.videoEditor animated: YES completion:nil];
Observed few times that providerDidBegin(_:) delegate never called for the complete app session after app init(as part of this CXProvider registered) which was built with SDK 26 and running on iOS 26.
This issue observed multiple times with our testing. Since there is no providerDidBegin:, client is marking CallKit as not ready and never report any calls for VoIP APNS and ended up in app crash due to "[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes]"
Please refer for sysdiagnose logs : FB19778306
For call reported in lockscreen, after updating the CXCallUpdate for an active callkit reported call with reportCallWithUUID:updated:. The display namer in the callkit UI is not getting updated.
This issue exists from iOS 18 and later. Issue is always seen.
Feedback updated with iOS 26 beta logs:
FB13969440
We've observed an issue where the video button on the CallKit UI is disabled during Video VoIP calls.
This issue appears to be specific to notch devices running SDK 26 and iOS 26 beta 7, specifically on iPhone 11. We have not seen this behavior on devices with Dynamic Island or on older iOS versions.
For further details, please refer to the attached video and sysdiagnose file. : FB19827793
Our experimentation suggests this issue is exclusively present on non-Dynamic Island devices with iOS 26 beta.
The crash log, an IPS file, indicates a crash occurred at a specific time, with the exception backtrace pointing to _terminateAppIfThereAreUnhandledVoIPPushes. However, cross-reference with the SysDiagnose logs, there is no corresponding process or activity for the application at the reported crash time. The app was not active, nor was it woken up by any event.
IPS file and SysDiagnose logs have been attached in the Feedback.

There consistent build failure in Xcode Beta 26.0 (Build 24112) on a project targeting iOS. The build process fails with an error indicating that the actool utility is unable to decode its own version information, leading to the overall build failure.
error: Failed to decode version info for '/Applications/Xcode26.0.app/Contents/Developer/usr/bin/actool': The data couldn’t be read because it is missing.

Application has specified the bluetooth-central background mode.
Peripheral Device(BLE) is connected to the iPhone.
Application will initiate a request 'retrieveConnectedPeripheralsWithServices' along with list of services to scan for.
Application will receive a list of peripherals connected to the system whose service UUID's match.
From the list of peripherals, application will initiate a request 'connectPeripheral' with the interested peripheral along with the option set to 'CBConnectPeripheralOptionEnableAutoReconnect'. This option is available from iOS 17+.
CBConnectPeripheralOptionEnableAutoReconnect - This option will help in reconnect back to peripheral when peripheral becomes available. (Turn OFF and Turn ON)
How do we achieve the same thing in earlier IOS version
We have an application WAVE PTT(Push to talk) and
Application is in foreground state, When a user receives a cellular call and it is in the "ringing" state and application receives a VoIP APNS(video call) which is reported to CallKit.
User rejects the Cellular call from CallKit UI, application Video call is also getting rejected (separate feedback - 19017978) and Here the issue is observed that an Application moved to background(OS26 beta 9).
Issue is not observed in iOS 18 and older versions.
Frequency : 1 out of 3.
Please refer the sysdiagnose logs in below reported feedback ID.

default 2025-09-10 12:30:06.991950 +0530 WAVE PTX 0x10e078100 - ApplicationStateTracker: UISceneDidEnterBackground
Steps To reproduce:
Login to application and App has joined the PTC channel.
Push the application to background and Lock the device.
From the System UI press the talk button which will start transmit.
Audio Session has been activated and Audio unit has been initialised properly.
On terminator side no media is being played out.
Issue observed consistently on specific models which has configured audio codec with Stereo type.

We require assistance in resolving a critical audio design conflict within our Push-to-Talk (PTT) application. Our current volume amplification strategy—which relies on applying a GAIN factor to PCM samples in conjunction with setting the AVAudioSession category to Playback—is working successfully when PTT is used independently. However, upon integrating and reporting the same PTT call through the CallKit framework, this amplification effect is lost. The CallKit integration appears to be forcing a different, non-amplifying audio session category or configuration, negatively impacting the user's perceived call volume. We need guidance on how to maintain the AVAudioSessionCategoryPlayback setting, or an equivalent high-volume configuration, while operating under the control of CallKit.
The iOS application is a Central Manager connected to a Bluetooth Low Energy (BLE) accessory that utilizes the Hands-Free Profile (HFP).
When the application plays a notification tone (using AVAudioPlayer or System Sounds), the audio is incorrectly routed to the device's internal speaker instead of the active HFP headset.
How do we programmatically ensure that these notification tones are automatically and reliably routed to the connected HFP headset
