For iOS17 we've had no problem playing Apple Fairplay encrypted content with keys delivered from our key server running on FairPlay Streaming Server SDK 5.1 and subsequently FairPlay Streaming Server SDK 26. It's built and deployed using Xcode Version 26.1.1 (17B100) with no changes to the code and - as expected - the content continued to be successfully decrypted and played (so far so good). However, as soon as a device was updated to iOS26, that device would no longer play the encrypted content. Devices remaining on iOS17 continue to work normally and the debugging logs are a sanity-check that proves that. Is anyone else experiencing this issue? Here's the code (you should be able to drop it into a fresh iOS Xcode project and provide a server url, content url and certificate).

Hi folks - I'm having trouble finding specific documentation about Audio Unit MIDI plugins - as in MIDI -only. Any suggestions welcome as searches aren't returning much. (too niche? user error?)

Hello, I requested Fairplay credentials a week ago. Where can I check the status of my request? Thank you very much. The team ID is: 6WZ8SVRYV9

I'm using this library: https://github.com/Yummypets/YPImagePicker to capture photos. I've modified it slightly, and I'm using an older version. When testing on my iPhone 16e, ios 26, whenever I take a photo, I get the following two error messages: <<<< FigXPCUtilities >>>> signalled err=-17281 at <>:302 <<<< FigCaptureSourceRemote >>>> Fig assert: "err == 0 " at bail (FigCaptureSourceRemote.m:569) - (err=-17281) These error messages appear, but as far as I can tell, the photo comes through OK, and I can save the data no problem. I've even removed all my handling code to see if it was something I was doing. I don't really want to ship with these errors showing, but I also have no idea what can be causing this error to appear. chatgpt was not helpful diagnosing this. Does anyone know what can cause this error Is there a way I can see the source code to figure out if there's something I'm doing wrong here? It really seems like this is an internal apple error, or else I would have expected more details on the error relating to the code I've written. Any clues would be appreciated!

Avplayer encapsulates a player. After connecting to an Apple Bluetooth headset, it immediately reports an error. Non-Apple Bluetooth headsets can be played, but currently the issue is that the player works normally in one app but not in another. We are an educational app.

Hi Is it possible to have a playlist where I have a indication of a stream in clear, but then, someone started a DRM encrypted period and then someone turns it off. Can I just do the following (I've removed the video segments part, I'm just interested in the parts where I want notify the new drm region )? #EXT-X-MAP:URI="video_2_10000000_t17586401730000000_init.mp4" #EXT-X-KEY:METHOD=NONE ... #EXT-X-MAP:URI="video_2_10000000_t17587374640000000_init.mp4" #EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://5df0b36ac4bb4d0ff954a73b502ac332",KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1" ... #EXT-X-MAP:URI="video_2_10000000_t17587376740000000_init.mp4?" #EXT-X-KEY:METHOD=NONE Should I insert discontinuity tags or something else? Right now what I can observe is that I got some audio drops when I try to do this.

Device: iPhone 17 Pro iOS Version: iOS 26.1 Camera: Ultra-wide (0.5x) using AVCaptureSession Our camera app freezes on iPhone 17 when switching frame rates (30fps ↔ 60fps). This works fine on iPhone 16 Pro and earlier. What We've Observed: Freeze happens on frame rate change - particularly when stabilization was enabled Thread.sleep is used - to allow camera hardware to settle before re-enabling stabilization Works on older iPhones - only iPhone 17 exhibits this behavior Console shows these errors before freeze: 17281 <<<< FigXPCUtilities >>>> signalled err=18446744073709534335 <<<< FigCaptureSourceRemote >>>> err=-17281 Is Thread.sleep on the main thread causing the freeze? Should all camera configuration be on a background queue? Is there something specific about iPhone 17 ultra-wide camera that requires different handling? Should we use session.beginConfiguration() / session.commitConfiguration() instead of direct device configuration? Is calling setFrameRate from a property's didSet (which runs synchronously) problematic? Are the FigCaptureSourceRemote errors (-17281) indicative of the problem, and what do they mean?

quotes are displayed incorrectly in subtitles of AVPlayerViewController when streaming VOD content using HLS. single quote ' (escaped ') is displayed as apos; double quotes " (escaped ") is displayed as quot; following the vtt specification. The same stream works fine in VLC player, showing quotes correctly in subtitles. subtitle vtt files use Content-Type: text/vtt WEBVTT X-TIMESTAMP-MAP=LOCAL:490014:06:04.000,MPEGTS:158764568760056 example line: 490014:05:46.000 --> 490014:05:50.440 align:start line:83% position:14% and the playlist has: #EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",LANGUAGE="da",NAME="Dansk",AUTOSELECT=YES,CHARACTERISTICS="public.accessibility.transcribes-spoken-dialog,public.accessibility.describes-music-and-sound",URI="subs/dan_5/playlist.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=780000,CODECS="mp4a.40.5,avc1.42c01e",RESOLUTION=256x144,AUDIO="audio-aac",SUBTITLES="subs" lære dig endnu bedre at kende." adding 'wvtt' to CODECS list in playlist does not make a difference. Is this a known bug? Is there a workaround? I guess the AVResourceLoaderDelegate can be used to intercept and parse the subtitle files, but it seems like quite a hack and not really intended to be used for this.

I'm trying to benchmark a Core Image filter chains memory footprint and notice a weird quirk in instruments. On a real device, even with a simple Core Image chain, the memory balloons each time I ran the filter. See attached screen shots. Running on iPhone 17 Pro: Running on simulator (M2 Macbook Pro) As you can see there's a huge build up of 4MB "VM: IOSurface" memory on the real device, but the simulator seems to clean it up correctly. Here's my basic code: func processImage() { guard let inputImage = ContentViewModel.loadImageFromBundle(name: "kitty.HEIC") else { print("Failed to load sample_image from bundle") return } var outputImage = inputImage outputImage = outputImage.applyingFilter("CIBloom", parameters: [ kCIInputRadiusKey: 20, kCIInputIntensityKey: 0.8 ]) DispatchQueue.global(qos: .userInitiated).async { let data = self.context.jpegRepresentation(of: outputImage, colorSpace: CGColorSpace(name: CGColorSpace.sRGB)!) if let data = data, let uiImage = UIImage(data: data) { DispatchQueue.main.async { self.displayImage = Image(uiImage: uiImage) } } } } Why is this happening? Seems like a bug to me or I need to release an object. At the very least makes it challenging to measure memory usage. Any help is greatly appreciated. Alex

Hi, We identified massive amounts of leaked memory with the tvOS 26 standard player user interface as soon as chapters (navigation markers) are involved. Artwork images associated with chapters are not correctly released anymore, leaking memory in chunks of several MiBs. Over time apps will be terminated by the system due to excessive memory consumption. The issue was reported to Apple as tvOS 26 regression: Huge memory leaks associated with navigation marker artworks displayed in the tvOS standard user interface, filed under FB21160665.

hi all, as soon an audio is played in a whatever app, coreaudiod inserts a sleep prevent assertion for both, the system AND the display. can i somehow stop the insertion of the display sleep assertion? pid 223(coreaudiod): [0x00004e9e00058dc2] 00:03:18 PreventUserIdleDisplaySleep named: "com.apple.audio.AppleGFXHDAEngineOutputDP:10001:0:{B31A-08C6-00000000}.context.preventuseridledisplaysleep" Created for PID: 4145. where PID 4145 is spotify. but it doesn't matter which app is playing the audio. any help would be appreciated thanks

I want to confirm if this is a bug or a programming error. Very easy to reproduce it by modifying AVCam sample code. Steps to reproduce: Add AVCaptureVideoDataOutput to AVCaptureSession, no need to set delegate in AVCam sample code (CaptureService actor) private let videoDataOutput = AVCaptureVideoDataOutput() and then in configureSession method, add the following line try addOutput(videoDataOutput) if videoDataOutput.availableVideoPixelFormatTypes.contains(kCVPixelFormatType_420YpCbCr8BiPlanarFullRange) { videoDataOutput.videoSettings = [kCVPixelBufferPixelFormatTypeKey as AnyHashable as! String : kCVPixelFormatType_420YpCbCr8BiPlanarFullRange] } And next modify set HDR method: /// Sets whether the app captures HDR video. func setHDRVideoEnabled(_ isEnabled: Bool) { // Bracket the following configuration in a begin/commit configuration pair. captureSession.beginConfiguration() defer { captureSession.commitConfiguration() } do { // If the current device provides a 10-bit HDR format, enable it for use. if isEnabled, let format = currentDevice.activeFormat10BitVariant { try currentDevice.lockForConfiguration() currentDevice.activeFormat = format currentDevice.unlockForConfiguration() isHDRVideoEnabled = true if videoDataOutput.availableVideoPixelFormatTypes.contains(kCVPixelFormatType_420YpCbCr10BiPlanarVideoRange) { videoDataOutput.videoSettings = [kCVPixelBufferPixelFormatTypeKey as AnyHashable as! String : kCVPixelFormatType_420YpCbCr10BiPlanarVideoRange] } } else { captureSession.sessionPreset = .high isHDRVideoEnabled = false if videoDataOutput.availableVideoPixelFormatTypes.contains(kCVPixelFormatType_32BGRA) { print("Setting sdr pixel format \(kCVPixelFormatType_32BGRA)") videoDataOutput.videoSettings = [kCVPixelBufferPixelFormatTypeKey as AnyHashable as! String : kCVPixelFormatType_32BGRA] } try currentDevice.lockForConfiguration() currentDevice.activeColorSpace = .sRGB currentDevice.unlockForConfiguration() } } catch { logger.error("Unable to obtain lock on device and can't enable HDR video capture.") } The problem now is toggling HDR on and off no longer works in video mode. If after setting HDR on, you set HDR to off, active format of device does not change (setting sessionPreset has no effect). This does not happen if video data output is not added to session. Is there any workaround available?

Hello, We are experiencing on some occasions a wrong behavior with PDFDocument method: func page(at index: Int) -> PDFPage? With certain PDF files, this method returns the wrong PDFPage. This occurs on iOS 18.3, 18.5 and 18.6.2 (an maybe on other versions). Try this PDF for instance (page 81 is returned when index = 2): https://drive.google.com/open?id=1MHm2wjfsbWB8OiRmARUMmvODYxp4DIqP&usp=drive_fs Also, I mention that this doesn't occur systematically with this PDF. When making a copy of this file we don't observe the issue. Could this be linked some kind of internal cache issue ?

Hello, I'm investigating an issue with LL-HLS playback using AVPlayer, specifically during DVR Live seeking (seeking to a past time). I noticed that in certain seeking scenarios, AVPlayer sends a Blocking Playlist Reload request that includes the _HLS_msn parameter but is missing the _HLS_part parameter. While I understand this is compliant with the HLS spec, I would like to know the specific criteria AVPlayer uses to decide when to drop the _HLS_part parameter. Does AVPlayer intentionally omit the part info when it determines that loading a specific partial segment is unnecessary during a seek operation? Clarification on this behavior would help us greatly in debugging our stream delivery. Thanks in advance.

Hey Swift community! I'm exploring building a macOS app that needs to monitor what's currently playing in music apps like Spotify and Apple Music (track info, playback position, play/pause state). I'm trying to figure out the most efficient architecture before diving in. The Goal: Monitor playback state across multiple music players to react to changes in real-time, ideally with minimal CPU overhead since this would run continuously in the background. Approaches I'm Considering AppleScript / ScriptingBridge Distributed Notifications Native Frameworks (Apple Music only) What's the recommended way to do this on macOS? Are distributed notifications reliable enough to avoid polling entirely? Is there a performance difference between AppleScript and ScriptingBridge for IPC? For Apple Music specifically, should I use MusicKit, MediaPlayer, or stick with AppleScript? Are there other approaches I'm missing?

I believe this should work: CFMutableDictionaryRef attrs = CFDictionaryCreateMutable(kCFAllocatorDefault, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionaryAddValue(attrs, kCVImageBufferColorPrimariesKey, kCVImageBufferColorPrimaries_ITU_R_709_2); CFDictionaryAddValue(attrs, kCVImageBufferTransferFunctionKey, kCVImageBufferTransferFunction_ITU_R_709_2); CFDictionaryAddValue(attrs, kCVImageBufferYCbCrMatrixKey, kCVImageBufferYCbCrMatrix_ITU_R_709_2); CVPixelBufferRef pixelBuffer = NULL; CVPixelBufferCreate(kCFAllocatorDefault, width, height, kCVPixelFormatType_32ARGB, attrs, &pixelBuffer); assert(CFDictionaryGetCount(CVBufferGetAttachments(pixelBuffer, kCVAttachmentMode_ShouldPropagate)) > 0); But that last assert fails, so it appears the color info does not get attached. kCVImageBufferColorPrimariesKey and the others are not one of the keys listed under BufferAttributeKeys, but I think they're supposed to be allowed because they're listed by CMVideoFormatDescriptionGetExtensionKeysCommonWithImageBuffers(). I'm hoping that putting the color matrix info in there will control how AVAssetWriter converts the RGB to YCbCr.

Hi, I'm trying to create a FairPlay Streaming Certificate for the SDK 26.x version. Worth to mention that we already have 2 (1024 and 2048) and we only have the possibility to use our previous 1024-bit certificate (which we do not want because we want a 2048 cert) Our main issue is that when I upload a new "CSR" file, the "Continue" button is still on "gray" and cannot move forward on the process. The CSR file has been created with this command: openssl req -out csr_2048.csr -new -newkey rsa:2048 -keyout priv_key_2048.pem -subj /CN=SubjectName/OU=OrganizationalUnit/O=Organization/C=US Some help will be appreciated. Thanks in advance Best,
