I am playing the protected HLS streams and the authorization token expires in 3 minutes. I am trying to achieve this with 'AVAssetResourceLoaderDelegate'. I can refresh the token and play it, but the problem is in between the session, the player stalls for a small time, LIKE 1 SECOND.

Hello, We are developing a real-time speech recognition application and are utilizing AVAudioEngine with voice processing enabled on the input node. However, we have observed that enabling this mode interferes with the built-in iOS screen recording feature - specifically, the recorded video does not capture any audio when this mode is active. Since we want users to be able to record their experience within our app, this issue significantly impacts our functionality. Is there a known workaround or recommended approach to ensure that both voice processing and screen recording can function simultaneously? Any guidance would be greatly appreciated. Thank you!

I found some documentation about Kext, but I heard they have now moved to Dext. So I was wondering if Dext could completely imitate the previous Kext. https://developer.apple.com/documentation/kernel/implementing_drivers_system_extensions_and_kexts This page is written like this Important In macOS 11 and later, the kernel doesn’t load a kext if an equivalent DriverKit solution exists. You may continue to use kexts in macOS 10.15 and earlier.

Mobile app - Ellie's Gift https://apps.apple.com/gb/app/ellies-gift/id1617597875 Using AVFoundation to play audio tracks within the app. Has always been working fine across apple and android, but iphone 14 and newer devices are unable to play audio. Any idea's or suggestions?

We are getting reports from customers that they are not able to play videos in our app after updating their phones to iOS18.3.1. (Further checking indicates that it happens on all iOS18 versions. It suddenly started occurring from February 18th, 2025) When checking logs we see that playback is failing due to CoreMediaErrorDomain error -42709. This is an undocumented error code and hence we do not know the cause of the playback issue. Does anyone know what this error code means and how the app should handle it? Reported as FB16638501.

We are using AVAssetDownloadURLSession to download content with multiple audio tracks. Still, we are facing an issue where only one audio language is being downloaded, despite explicitly requesting multiple audio languages. However, all subtitle variants are being downloaded successfully. Issue Details: Observed Behaviour: When initiating a download using AVAssetDownloadURLSession, only one audio track (Hindi, in this case) is downloaded, even though the content contains multiple audio tracks. Expected Behaviour: All requested audio tracks should be downloaded, similar to how subtitle variants are successfully downloaded.

Hi, I am recording a video at 240 FPS within my application and saving it to the Photos app. The recorded video retains 240 FPS in the Photos app. However, after trimming the video using the Photos app and importing it back into my app, the FPS is reduced to 30 FPS. Steps to Reproduce: Record a video inside the application at 240 FPS. Save the recorded video to the Photos app. Verify that the video retains 240 FPS in the Photos app. Trim the video using the built-in Photos app editor. Import the trimmed video back into the application. The FPS of the imported video is now reduced to 30 FPS. Code Used for Importing Video: I am using the following code to fetch the video from the Photos app: let options: PHVideoRequestOptions = PHVideoRequestOptions() options.version = .current // Using `.original` preserves FPS, but I need `.current` for other changes options.deliveryMode = .highQualityFormat options.isNetworkAccessAllowed = true PHImageManager.default().requestAVAsset(forVideo: self, options: options) { (avAsset, audioMix, info) in if let urlAsset = avAsset as? AVURLAsset { completionHandler(urlAsset.url, self) } else { self.askForOriginal(completionHandler: completionHandler) } } Observations: The original video retains 240 FPS until it is trimmed in the Photos app. After trimming, the FPS automatically drops to 30 FPS when imported back into the app. If I use options.version = .original, the FPS is preserved, but I need .current to apply other modifications. Questions: Is this an expected behavior of PHImageManager when requesting a video with options.version = .current? Is there a way to preserve the original FPS while still using .current? Are there any workarounds to extract the trimmed video without FPS reduction? Any insights or solutions would be greatly appreciated. Thanks in advance!

I found that when the development tool above Xcode16 ran my app, I opened the suspended inscription function, and then opened the system camera, the content in the suspended window would not be displayed, and the suspended window would have a black screen. However, this phenomenon does not appear on Xcode15.4 development tools, it is the same code, I do not know why

Hi There, I have an app which access the media library, to save and load files. Since the IOS 18.2, the access to the media library stopped working. Now, I've noticed that our App doesn't show in the List of apps with access to Files ( Privacy & Security -> Files & Folders). Weird behavior is that, one iPhone with iOS 18.3.1 can access to the Files but others no, same iOS version 18.3.1. Test on Simulators (MAC) and works fine also. My info.plist file have the keys to access media library for long time and hasn't changed (at least in the las 4 years) including the key "Privacy - Media Library Usage Description". Also, I've noticed, that the message (popup) that request access to the media library, when using the app for the first time, doesn't show up anymore. We request access to the network (wifi) and this message still showing up but no the media library. I'm using Visual Studio with Xamarin on a MAC. I really appreciate any help you can because is very odd behavior and this started from the iOS 18.2.

Hello Apple, i've been using ios for many years and never had any issues with urdu language keyboard, but since the new 18.4 beta update some words are not working correctly as it should like a name of my friend who's name is "راعنیہ" but the new updated version cannot type is together and keep seperating like "راعنی ہ" its so frustrating to use like that and its not just one but so many other words that it just cannot do properly also the new font and no gap concept its hurting my eyes so much while reading or even typing.. i hope apple fixes that asap.. thankyou

The presentation "create audio drivers with DriverKit" from WWDC 2021 demonstrates how to use a dext to implement a virtual audio driver. It also says " If a virtual audio driver or device is all that is needed, the audio server plug-in driver model should continue to be used". Indeed, in AudioDriverKit/AudioDriverKitTypes.h, there is no IOUserAudioTransportType Virtual, although CoreAudio/AudioHardwareBase.h includes kAudioDeviceTransportTypeVirtual. For one of our products, we require virtual devices to implement a software loopback "cable". We've implemented this using the "traditional" HAL plugin, and as a proof-of-concept, also using a dext. In the dext, I tried setting the transport type to 'virt', which seems to only have the effect of changing the icon shown in Audio Midi Setup. HAL plugins require an installer, and the installer has to kill coreaudiod in a post-install script. You have to turn off SIP to debug them. Just like AudioDriverKit drivers, they are out-of-process and run in a process not owned by the hosting app. Our HAL plugin's interface is property based; we had to write a lot of boiler-plate code to implement required properties. Writing an AudioDriverKit driver is in most respects easier - a lot of the scaffolding is implemented in the base driver, which we only alter where required. Debugging and installation is much easier. The dext works just fine, as far as we can ascertain, just as well as a HAL plugin. So, my question is - is the advice to use a HAL plugin for a virtual device still correct in 2025? And if so, what's the objection? We'd really prefer to ship the AudioDriverKit virtual audio device.

Bug Report: ScreenCaptureKit System Audio Capture Crashes with EXC_BAD_ACCESS Summary When using ScreenCaptureKit to capture system audio for extended periods, the application crashes with EXC_BAD_ACCESS in Swift's error handling runtime. The crash occurs in swift_getErrorValue when trying to process an error from the SCStream delegate method didStopWithError. This appears to be a framework-level issue in ScreenCaptureKit or its underlying ReplayKit implementation. Environment macOS Sonoma 14.6.1 Swift 5.8 ScreenCaptureKit framework Detailed Description Our application captures system audio using ScreenCaptureKit's audio capture capabilities. After successfully capturing for several minutes (typically after 3-4 segments of 60-second recordings), the application crashes with an EXC_BAD_ACCESS error. The crash happens when the Swift runtime attempts to process an error in the SCStreamDelegate.stream(_:didStopWithError:) method. The crash consistently occurs in swift_getErrorValue when attempting to access the class of what appears to be a null object. This suggests that the error being passed from the system framework to our delegate method is malformed or contains invalid memory. Steps to Reproduce Create an SCStream with audio capture enabled Add audio output to the stream Start capture and write audio data to disk Allow the capture to run for several minutes (3-5 minutes typically triggers the issue) The app will crash with EXC_BAD_ACCESS in swift_getErrorValue Code Sample func stream(_ stream: SCStream, didStopWithError error: Error) { print("Stream stopped with error: \(error)") // Crash occurs before this line executes } func stream(_ stream: SCStream, didOutputSampleBuffer sampleBuffer: CMSampleBuffer, of type: SCStreamOutputType) { guard type == .audio, sampleBuffer.isValid else { return } // Process audio data... } Expected Behavior The error should be properly propagated to the delegate method, allowing for graceful error handling and recovery. Actual Behavior The application crashes with EXC_BAD_ACCESS when the Swift runtime attempts to process the error in swift_getErrorValue.

Impact This issue prevents reliable long-duration audio capture using ScreenCaptureKit. This bug significantly limits the usefulness of ScreenCaptureKit for any application requiring continuous system audio capture for more than a few minutes. Perhaps this issue might be related to a macOS bug where the system dialog indicates that the screen is being shared, even though nothing is actually being shared. Moreover, when attempting to stop sharing, nothing happens.

Is it possible to use the AVExternalStorageDevice to access external storage from a connected camera or usb drive (via USB C or Lightning connector) on an iPad/iPhone. I have tested the following code on an iPhone 14 (iOS 18.1.1) and an iPad Gen 10 (18.3.1), and both return false for: // returns false on iPhone 14, iPad gen 10 print(AVExternalStorageDeviceDiscoverySession.isSupported) The following code returns null, when I try to access the external storage discovery session. // returns null on iOS devices print(AVExternalStorageDeviceDiscoverySession.shared) The following returns false, without displaying a permission dialog: AVExternalStorageDevice.requestAccess(completionHandler: { (granted: Bool) in // returns false with no permission dialog print(granted); What type of iOS devices are supported by AVExternalStorageDeviceDiscoverySession? What situations has it been used for (e.g. connecting to Camera via the external storage protocol, accessing photos from a SD card with an adapter, accessing photos from usb drive). Is there are sample code for using the AV External Storage api?

Hello All, I am looking for assistance with our FairPlay Streaming (FPS) certificates. We are in the process of migrating to a new video streaming vendor and need to create a new FPS certificate using SDK 4. However, we have reached the limit of allowed FPS certificates in our account and cannot create a new one. Issue Details: • We currently have two FPS certificates active in our developer account. • One of these was created using SDK 5, but our new vendor (Mux) requires an FPS certificate based on SDK 4. • Since Apple does not allow deleting FPS certificates from the developer portal, we are unable to create a new SDK 4 certificate. • We kindly request Apple to revoke one of our existing FPS certificates to allow us to generate a new SDK 4 certificate. Request: We would greatly appreciate it if you could assist us on how to delete one of our existing FPS certificates so that we can proceed with creating a new SDK 4 certificate for our vendor integration. Thank you for your support.
