We observed that the PHPicker is unable to load RAW images captured on an iPhone in some scenarios. And it is also somehow related to iCloud. Here is the setup: The PHPickerViewController is configured with preferredAssetRepresentationMode = .current to avoid transcoding. The image is loaded from the item provider like this: if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage) { itemProvider.loadFileRepresentation(forTypeIdentifier: kUTTypeImage) { url, error in // work } } This usually works, also for RAW images. However, when trying to load a RAW image that has just been captured with the iPhone, the loading fails with the following errors on the console: [claims] 43A5D3B2-84CD-488D-B9E4-19F9ED5F39EB grantAccessClaim reply is an error: Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application."

We think it is related to iCloud Photos: On the device that has iCloud Photos sync enabled, the picker is able to load the image right after it was synced to the cloud. On devices that don't sync the image, loading always fails. It seems that the sync process is doing some processing (?) of the image that will later enable the picker to load it successfully, but that's just guessing. Additional observations: This seems to only occur for images that were taken with the stock Camera app. When using Halide to capture RAW (either ProRAW or RAW), the Picker is able to load the image. When trying to load the image as kUTTypeRawImage instead of kUTTypeImage, it also fails. The picker also can't load RAW images that were AirDroped from another device, unless it synced to iCloud first. This is reproducable using the Selecting Photos and Videos in iOS sample code project. We observed this happening in other apps that use the PHPicker, not just ours. Is this a bug, or is there something that we are missing?

Hello, I am getting the following errors when building a Mac Camera Extension with web sockets. I am using URLSessionWebsocketTask as my web socket library. I built a test program for my code and in there I can see my web sockets are working properly, but when I run it from the System Extension I get the following errors. The socket opens for two - three messages then crashes. I couldnt find any documentation online for the following errors CMIOExtensionProvider.m:1975:-[CMIOExtensionProvider removeProviderContext:]_block_invoke Unregistered provider context <CMIOExtensionProviderContext: ->, don't be surprised if things go badly CMIOExtensionProviderContext.m:64:-[CMIOExtensionProviderContext initWithConnection:]_block_invoke [391] received Connection invalid``

I'm getting an error writing a ciImage as a heif image: // Create CIImage directly from pixel buffer let ciImage = CIImage(cvPixelBuffer: pixelBuffer, options: [CIImageOption.properties: combinedMetadata]) // Write HEIC synchronously do { try ciContext.writeHEIFRepresentation(of: ciImage, to: url, format: .RGBA8, colorSpace: colorSpace) The error I'm getting is: Error Domain=CINonLocalizedDescriptionKey Code=3 "(null)" UserInfo={CINonLocalizedDescriptionKey=failed to write HEIC data to file., NSUnderlyingError=0x11b1a1ec0 {Error Domain=CINonLocalizedDescriptionKey Code=10 "(null)" UserInfo={CINonLocalizedDescriptionKey=failed to add image to the PhotoCompressionSession.}}} Both try ciContext.writeJPEGRepresentation(of: copiedCIImage, to: url, colorSpace: colorSpace, options: options) and try ciContext.writePNGRepresentation(of: copiedCIImage, to: url, format: .RGBA8, colorSpace: colorSpace) work. I also verified that the code works with iOS 18. Is there something new we need to do for Heif images? Thanks in advance

Dear Sirs, I'd like to add an icon to my audio driver based on AudioDriverKit. This icon should show up left of my audio device in the audio devices dialog. For an Audio Server Plugin I managed to do this using the property kAudioDevicePropertyIcon and CFBundleCopyResourceURL(...) but how would you do this with AudioDriverKit? Should I use IOUserAudioCustomProperty or IOUserAudioControl and how would I refer to the Bundle? Is there an example available somewhere? Thanks and best regards, Johannes

Hi All I have some problem when I using the IOS 18.4.1 I have iphone16 pro and ipad Air, both are updated to IOS 18.4.1 I tried to following sample code. However, when I run the app around 30 seconds to 1 minutes, the application would be crashed When I using another Ipad with IOS 17, it would not have the same problem. https://developer.apple.com/documentation/createml/creating-an-action-classifier-model https://developer.apple.com/documentation/createml/detecting_human_actions_in_a_live_video_feed#overview%29,

Here is the demo from Apple's site This issues is specific to iOS 18. When running this demo, we are getting new text when we have a gap in speaking, the recognitionTask(with:resultHandler:) provides new text which is only spoken after the gap and not the concatenation of old text and the new spoken text.

So experimenting with the new SpeechTranscriber, if I do: let transcriber = SpeechTranscriber( locale: locale, transcriptionOptions: [], reportingOptions: [.volatileResults], attributeOptions: [.audioTimeRange] ) only the final result has audio time ranges, not the volatile results. Is this a performance consideration? If there is no performance problem, it would be nice to have the option to also get speech time ranges for volatile responses. I'm not presenting the volatile text at all in the UI, I was just trying to keep statistics about the non-speech and the speech noise level, this way I can determine when the noise level falls under the noisefloor for a while. The goal here was to finalize the recording automatically, when the noise level indicate that the user has finished speaking.

Hi, After updating to iOS 26, our app is facing playback failures with AVPlayer. The same code and streams work fine on iOS 18 and earlier. Error - Domain[CoreMediaErrorDomain]:Code[-15628]:Desc[The operation couldn’t be completed.]:Underlying Error Domain[(null)]:Code[0]:Desc[(null)] Environment: iOS version: ios 26 React Native: 0.69 Video library: react-native-video (AVPlayer under the hood) Stream type: HLS (m3u8) with segment (.ts) files Observed behaviour: Playback works initially on iOS 26. On iOS 26, the stream fails at runtime after a few seconds/minutes (not on first load). Network logs show 307 redirects on some segment requests. After this, AVPlayer throws the above error. Playback fails intermittently on slow/unstable networks.

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

We have implemented offline Fairplay playback and it works fine.But at times when trying to playback the offline downloaded content, we get the following error"An unknown error occured (-42650)"Tried looking up the error in the documentation but couldnt find anything relevant.What could possibly be creating this error?

Hello, I am wondering how one can play music videos (with the actual video playing) with the ApplicationMusicPlayer using MusicKit for Swift? There is not much documentation on this, so any help would be appreciated.

I am seeing a crash on iOS 18.0 in my app due to PHImageManager.default().requestImage. Same crash is seen even while using requestImageDataAndOrientation. Not sure why this is happening only on iOS 18.0. Any help on this would be appreciated.

Hello, As far as I know and in all of my testing there is no way for a user or a developer to change the frame rate of the video output on iPadOS. If you connect an iPad via a USB Hub or a USB to HDMI Adaptor and then connect it to an external monitor it will output at 59.94fps. I have a video app where a user monitors live video at 25fps and 30fps, they often output to an external display and there are times when the external display will stutter due to the mismatch in frame rate, ie. using 25fps and outputting at 59.94fps. I thought it was impossible to change the video output frame rate, then in V3.1 of the Blackmagic Camera App I saw an interesting change in their release notes: ‘Support for HDMI Monitoring at Sensor Rate and Resolution’ This means there is some way to modify it, not sure if this is done via a Private API that Apple has allowed Blackmagic to use. If so, how can we access this or is there a way to enable this that is undocumented? Thanks!

Hello everyone, I am looking for a solution to programmatically, e.g. using AppleScript to import photos into the Photos library on MacOS and also push them to the shared library, like it can be done using the standard GUI of the Photos application. Maybe it is not possible using AppleScript, but using a short Swift script and PhotoKit, I do not not know. Any help is appreciated! Thomas

i tried combine speech detector and speech transciber to anlayzer. but speech detector is not speech module. please help me

Hi, I'm working on an AUv3 project. The app itself displays my icon. However the Auv3 extension does not display any icon in any host app (AUM, Drambo, etc.0). I thought that the extension would inherit the host app icon but that it does not appear to be the case. I tried to add the icon as a 1024x1024 file to the extension target and the update my extension plist file withe a CFBundleIconFile key but no luck either. It must surely be really easy. What am I missing? Thanks in advance for your help!

I received my approval for FairPlay Streaming (FPS) and was getting things organized and then my computer crashed. So... Yes, I lost the 32 digit Account Security Key (ASk) that I was warned not to lose repeatedly... I understand that I can't query apple for the existing ASk. I don't see where I can delete the existing cert to request another one. So I assume I'll need to start from scratch either with another FPS approval process. Can someone please direct me on next steps for this boneheaded situation. Thank you

I am using https://developer.apple.com/documentation/applemusicapi/add-tracks-to-a-library-playlist to add tracks to playlists. This endpoint works fine for all playlists except for collaborative playlists. For collaborative playlist I get the following 500 error as a response: "errors": [ { "id": "<some id>", "title": "Upstream Service Error", "detail": "Unable to update tracks", "status": "500", "code": "50001" } ] } Steps to reproduce: Create a playlist in your library. Use the api to add a song. Confirm that it works. Make that same playlist collaborative. Update the playlist ID in your api request (as making a playlist collaborative changes its id) Confirm that you get the 500 error.

Hello, I have a problem generating a 2048-bit FairPlay Streaming certificate. I tried generating SDK v26.x certificate in two ways. (1) Use existing certificate (2) Create new certificate Though, in both ways, Apple gives me a certificate bundle of 1024-bit certificate. (fps_certificate.bin) I've uploaded 2048-bit CSR on creating a certificate. Just to note, I have created a SDK v4.x certificate few years ago. Have anyone bumped into a same issue? Or am I missing something?
