I am reaching out regarding an issue with my Apple FairPlay Streaming Certificate. To generate the certificate signing request (CSR), I used the following OpenSSL commands: openssl genrsa -out private_key.pem 1024 openssl req -new -key private_key.pem -out request.csr However, according to the guide provided by Apple and instructions from my DRM provider, I should have used: openssl genrsa -aes256 -out privatekey.pem 1024 openssl req -new -sha1 -key privatekey.pem -out certreq.csr -subj "/CN=SubjectName /OU=OrganizationalUnit /O=Organization /C=US" I suspect this discrepancy might be causing the issue with my FairPlay certificate. After obtaining the fairplay.cer file and importing it into Keychain Access, I noticed the following: When I expand the certificate in Keychain Access, I can only see a public key and no private key. As a result, I am unable to export the certificate as a .p12 file, as this option is disabled. As per my DRM provider's instructions, I need to export the certificate along with the corresponding private key as a .p12 file with a password. Since the private key is not visible in Keychain Access, I am unable to proceed further. I have read the FairPlay Streaming Overview but could not find any reasons as to why this issue is occurring or guidance on the procedure to revoke a certificate. Additionally, I came across the terms and conditions which mentioned reaching out to product-security at Apple for assistance in revoking corrupt certificates. However, despite reaching out, I have not received a response. Any help on how to proceed will be great!

Can anyone explain how AVAssetExportSession works in iOS 18 and earlier versions?

Hello everyone, I need some help about this things. If you also know, pls comment. Overview We are planning to develop an app using the “Support external cameras in your iPadOS app” feature introduced in iPadOS 17. Before implementing this feature, it is necessary for the iPad to recognize external cameras. However, among the iPad models compatible with iPadOS 17, we have found that some of the iPads owned by our development team can recognize external cameras, while others cannot. If you have any reports regarding compatibility issues or information on how to resolve these problems, please share them with us. Detailed Explanation: The results of our investigation are as follows: External Camera Used: A 360-degree camera Devices Firmware RICOH Theta X 2.61.0（2024/12/26Latest） RICOH Theta Z1 Tested iPad Devices Firmware Status 12.9インチiPad Pro（第3世代） IOS 17.5.1 OK 11インチiPad Pro（M4） IOS 18.2 NG Verification Method Step 1: Power on the iPad and the external camera, ensuring both are ready for connection. Step 2: Connect the iPad and the external camera using a USB-C cable. Step 3: Launch FaceTime on the iPad and check the displayed camera feed. If the external camera is recognized, the feed from the external camera will be displayed.

I've got a web app built with MusicKit that displays a list of songs. I have player controls for play, pause, skip next, skip, previous, toggle shuffle and set repeat mode. All of these work by using music. The play button, when nothing is playing and nothing is in the queue, will enqueue all the tracks and start playing with the below, for example: await music.setQueue({ songs, startPlaying: true }); I've implemented a progress slider based on feedback from the "playbackProgressDidChange" listener. Now, how in the world can I set the volume? This seems like it should be simple, but I am at a complete loss here. The docs say: "The volume of audio playback, which is set directly on the HTMLMediaElement as the HTMLMediaElement.volume property. This value ranges between 0, which would be muting the audio, and 1, which would be the loudest possible." Given that all my controls work off the music instance, I don't understand how I can do that. In this video from WWDC 2022, music web components are touched on briefly. These are also documented very sparsely. The volume docs are here. For the life of me, I can't even get the volume web component to display in the UI. It appears that MusicKit Web is hobbled compared to the native implementation, but surely adjusting volume shouldn't be that hard right? I'd appreciate any insight on how to do this, including how to get web components to work (in a Next JS app). Thanks.

Hi everyone, I wanted to bring up a question about Core Audio and its potential for future updates or improvements, specifically regarding latency optimization. As someone who relies on Core Audio for real-time audio processing, any enhancements in this area would be incredibly beneficial for professionals in the industry. Does anyone know if Apple has shared any plans or updates regarding Core Audio’s performance, particularly for low-latency applications? I’d appreciate any insights or advice from the community! Thanks so much! Best, Michael

If I call AudioDeviceStart on an AudioDevice in my application then "Hey Siri!" will not wake Siri up. Our users have complained that Siri does not get activated with my application is running. We found that calling AudioDeviceStart is causing the issue. How should we handle this?

Hey everyone😊, I am building an app that includes a live camera feed preview. That's all I need to do along side identifying the images with createML's image classification. I don't need to capture images at all. I've seen some very complicated tutorials. I just want to use a couple of lines of code.

How do we export a spatial video at a higher resolution than 2200 x 2200? For example, I want to export a video that I edited in a spatial timeline as 4096 x 4096 resolution with spatial metadata to output as an MV-HEVC file. I looked under both Final Cut and Compressor export settings, but couldn't find a way to do this. Thanks for your help!

Our app filters the photo library to a certain date range for ease of picking photos. However, to do this, we have to require full permissions to the photo library. We would like to use the PHPickerViewController and have it filter the results by the assets creation date? This would allow us to use it. I see other filter options, but not this one. And if it isn't there, is this something that is being thought about or on a roadmap?

Hello, I am experiencing slow image retrieval when using the requestImageForAsset:targetSize:contentMode:options:resultHandler: method in my application. The delay is significantly impacting the performance of my app. Here are the details of my implementation: for (PHAsset *asset in assets) { @autoreleasepool { PHImageManager *imageManager = [PHImageManager defaultManager]; PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init]; options.synchronous = YES; options.deliveryMode = PHImageRequestOptionsDeliveryModeFastFormat; options.resizeMode = PHImageRequestOptionsResizeModeNone; [imageManager requestImageForAsset:asset targetSize:CGSizeMake(100, 100) contentMode:PHImageContentModeAspectFill options:options resultHandler:^(UIImage *thumbnail, NSDictionary *info) { CameraRollCellDto *cellDto = [[CameraRollCellDto alloc] init]; cellDto.index = index; cellDto.thumbnail = thumbnail; cellDto.propertyDate = asset.creationDate; if (self.segmentedTorikomi.selectedSegmentIndex == SEG_INDEX_IKKATSU) { cellDto.isSelected = YES; } else { cellDto.isSelected = NO; } [list addObject:cellDto]; }]; index++; } } Has anyone else encountered this issue? Are there any known solutions or optimizations that can help improve the speed of image retrieval using this method? Thank you for your assistance.

I'd like to add a share extension to my app (an Action app extension, I think). The extension would appear when users share a photo in the Photos app (and, ideally, Safari). If you tapped my app icon on the share sheet, iOS would pass the photo to my app and switch the user from Photos or Safari to my full app, with the shared photo(s) available for my app to work with. I know this is possible, because Instagram (a third-party app) works exactly like this. If you look at an image in the Photos app, tap Share and then tap Instagram, iOS will background the Photos app, activate the Instagram app and let you edit and post your photo in the main Instagram app. It seems like NSExtensionContext#open(_:completionHandler:) might do this if I add a custom URL to my main app, but the documentation for that says: Each extension point determines whether to support this method, or under which conditions to support this method. In iOS, the Today and iMessage app extension points support this method. That would rule out an Action, Photo Editing or Share extension. But then how does Instagram do this, and how can I achieve the same in my app? I know that it's possible for an Action, Photo Editing or Share extension to open as a mini-app on top of the app providing the content. But coordinating the IPC for that is much, much more work (for my particular app) than just switching the user over to the app, with full access to all the functionality and data that my main app usually has access to.

I'm unable to play music using Musickit.js in the Chrome or Firefox browsers. Even using the apple guide here: https://js-cdn.music.apple.com/musickit/v1/index.html - I've added my Music Developer Token and song/album url, but it only works in Safari and not in Chrome or Firefox. I'm unsure if this is a global issue, or if there is something I need to do to enable playback in other browsers, but as it stands it's not working for me. Thanks for any help in advance!

Hello, I work on a video streaming app, and I have been working on this crash that we are seeing quite frequently (it is our #2 crasher at the moment). The stack trace indicates that an AVPictureInPictureController is being deallocated on a background thread. This leads to dangling AutoLayout constraints getting cleaned up, further resulting in an exception being thrown from the framework about the layout engine being accessed from a background thread. We have internal analytics which indicate that the crash occurs after the user comes back to the app after putting it in the background, and switches playback from Picture in Picture mode back to the app's regular playback UI. What has me puzzled here is that, as I'm sure you know, we have no control over the PIP UI. It is entirely system-provided, and there is none of our app's code in the stack trace. The whole process is even initiated by a KVO on an AVPlayerController property, and our app doesn't use that class directly anywhere. So how did we manage to cause this process to happen on a background thread? Add to this the fact that the bug only appeared once we switched to compiling with Xcode 16, and is overwhelmingly present only on devices running iOS 18. These factors lead me to believe that this is probably an OS issue. But before I go to file a feedback, I thought I would post here in case anyone has any ideas. I have attached an instance of the crash log to this post. 2025-01-08_17-32-45.7003_-0800-ea8d5c3323e0f1fc059cf83f6ec86377bdae1788.crash

Hello, I’m experiencing an issue with video playback in my Javascript (SvelteKit) application using Capacitor. The video plays and loops correctly on Android and web browsers (including Safari) but stops unexpectedly after a few iterations on iOS native App. <video src={videoPath} autoplay muted loop playsinline class="h-auto w-full max-w-full object-cover"></video> Has anyone encountered a similar issue or have insights into what might be causing this behavior on iOS? Any suggestions or workarounds would be greatly appreciated. Maybe it has something to do with the iOS power saving policy? Thank you in advance for your help!

I'm working with modern Core Audio API introduced in macOS Sequoia. I have an AudioHadwareDevice which has several controls of type AudioHardwareControl. I figured out to filter only volume controls I can use classID == kAudioVolumeControlClassID condition. Some devices have volume controls for both input and output. How I can determine the direction of the control? Streams, i.e. AudioHardwareStream object have direction, but I didn't found a way to map controls to streams. There are kAudioObjectPropertyScopeInput and kAudioObjectPropertyScopeOutput property scopes, but no matter what I tried controls always return false to any control.hasProperty(address: whatever). Any other ideas?

How can I use my RGB Curve points: let redCurve = [CIVector(x: 0, y: 0), CIVector(x: 0.235, y: 0.152), CIVector(x: 0.5, y: 0.5), CIVector(x: 1, y: 1)] let greenCurve = [CIVector(x: 0, y: 0), CIVector(x: 0.247, y: 0.196), CIVector(x: 0.5, y: 0.5), CIVector(x: 1, y: 1)] let blueCurve = [CIVector(x: 0, y: 0), CIVector(x: 0.235, y: 0.184), CIVector(x: 0.466, y: 0.466), CIVector(x: 1, y: 1)] in colorCurvesFilter which I've found in Apple Docs: func colorCurves(inputImage: CIImage) -> CIImage { let colorCurvesEffect = CIFilter.colorCurves() colorCurvesEffect.inputImage = inputImage colorCurvesEffect.curvesDomain = CIVector(x: 0, y: 1) colorCurvesEffect.curvesData = Data( bytes: [Float32]([ 0.0,0.0,0.0, 0.8,0.8,0.8, 1.0,1.0,1.0 ]), count: 36) colorCurvesEffect.colorSpace = CGColorSpaceCreateDeviceRGB() return colorCurvesEffect.outputImage! }

Hello everyone, I have a SwiftUI app using WKWebView to load a website that includes a form with a file input ().
