I have an app (currently in development stage) which needs to use ffmpeg, so I tried searching how to embed ffmpeg in apple apps and found this article https://doc.qt.io/qt-6/qtmultimedia-building-ffmpeg-ios.html
It is working correctly for iOS but not for macOS ( I have made changes macOS specific using chatgpt and traditional web searching)
Drive link for the file and instructions which I'm following: https://drive.google.com/drive/folders/11wqlvb8SU2thMSfII4_Xm3Kc2fPSCZed?usp=share_link
Please can someone from apple or in general help me to figure out what I'm doing wrong?
It's been an ask for a few years and I'm wondering if there are any plans, or whether the '26 SDKs/Tools allow Apple Music to work in the simulator? I develop for the Vision Pro so the usual 'fix' of running on the device is a bit of a hard ask.
At the very least a small sample library that works in the simulator would be welcome (similar to how photos works)
Cheers
In iOS 26, AVSpeechSynthesizer read Mandarin into Cantonese pronunciation.
No matter how you set the language, and change the settings of my phone system, it doesn't work.
let utterance = AVSpeechUtterance(string: "你好啊")
//let voice = AVSpeechSynthesisVoice(language: "zh-CN") // not work
let voice = AVSpeechSynthesisVoice(language: "zh-Hans") // not work too
utterance.voice = voice
et synth = AVSpeechSynthesizer()
synth.speak(utterance)

Hi,
In the iOS13 and macOS Catalina release notes it says:
Metal CIKernel instances now support arguments with arbitrarily structured data.
I've been trying to use this functionality in a CIKernel with mixed results. I'm particularly interested in passing data in the form of a dynamically sized array. It seems to work up to a certain size. Beyond the threshold excessive data is discarded and the kernel becomes unstable. I assume there is some kind of memory alignment issue going on, but I've tried various types in my array and always get a similar result.
I have not found any documentation or sample code regarding this. It would be great to know how this is intended to work and what the limitations are.
In the forums there are two similar unanswered questions about data arguments, so I'm sure there are a few out there with similar issues.
Thanks!

Hi folks:
I've been creating .reality files out of Reality Composer for over a year. Some of the files are up to 500 mB and, prior to the last month they opened fine as AR projected experiences on even basic iPhones and iPads. Now, I think since iOS 18, a 64Mb file will open as an AR experience but files it seems from about 350MB up don't open. Files just opens a window displaying the name of the file, that it's a .reality file and the file size. But it no longer opens into either an AR or Object display of the .reality scene. Has there been a new file size limit put on .reality files that Files will open or what else is going on here. Have a client who was about to launch and experience based on the .Reality file I can no longer open. Please help.
I am attempting to do batch Transcription of audio files exported from Voice Memos, and I am running into an interesting issue. If I only transcribe a single file it works every time, but if I try to batch it, only the last one works, and the others fail with No speech detected. I assumed it must be something about concurrency, so I implemented what I think should remove any chance of transcriptions running in parallel. And with a mocked up unit of work, everything looked good. So I added the transcription back in, and
1: It still fails on all but the last file. This happens if I am processing 10 files or just 2.
2: It no longer processes in order, any file can be the last one that succeeds. And it seems to not be related to file size. I have had paragraph sized notes finish last, but also a single short sentence that finishes last.
I left the mocked processFiles() for reference.
Any insights would be greatly appreciated.

Hi,
I am in need to get the total number of parquet files that are present in the apple music feed api for songs, artists. As there is option for limit and offset. But limit is limited to 200 records and offset is uncertain.
How to get total number of parquet files number without quering apple music feed api mulitple times?
Need help regarding this. Thanks!
We develop a video playback app on Apple TV which has the two following features:
Its content browsing screen has installed a gesture recognizer for presses on the PlayPause Siri remote button in order to directly launch a playback. The gesture recognizer is attached to the content browsing UIViewController view.
It presents its own custom playback UI with an AVPlayerLayer for the video and supports MPNowPlayingSession in order to publish current playback information and respond to remote commands. It also supports switching between fullscreen and Picture in Picture playback.
Both features work fine, ie. the playback is launched when pressing the PlayPause Siri remote button and, during playback, the playback info are properly advertised on other devices and remote commands are also triggered as expected.
However, when pressing the PlayPause Siri remote button while the video is playing in PiP, the "pause" remote command is sometimes triggered instead of the .playPause gesture recognizer. The issue may not occur the first time but for subsequent PlayPause presses. Navigating a bit in the app UI seems to help preventing the issue to occur.
Finally, the issue only occurs if the video is playing. If the video is paused, the PlayPause Siri remote button gesture is always recognized instead of the remote command.
Please note that, before using MPNowPlayingSession (and the corresponding MPRemoteCommandCenter), the app was using the default MPRemoteCommandCenter to support remote commands and the issue did not occur.
We don't reproduce this issue with the Apple TV app so there's probably something we are not doing right. Has someone any clue?

Hi,
I am trying to enable the default MIDINetworkSession in a Catalyst app on MacOS like this:
MIDINetworkSession.default().isEnabled = true
MIDINetworkSession.default().connectionPolicy = .anyone
In the AppSandbox I have both incoming and outgoing network connections enabled. And I also added the NSLocalNetworkUsageDescription key to the info.plist. Bonjour services are also added to the info.plist:
NSBonjourServices
_apple-midi._udp.
Nevertheless the session stays disabled. Running the same code works just fine on iOS.
Is there any special setup I need to make on MacOS to enable the MIDINetworkSession?
Thanks!
I'm building a camera app that does some post processing after the photo has been taken. With 12MP the processing is pretty good, but larger images 24MP is very slow.
I created a very simple example to demonstrate the issue, which is loading an image and the rendering it to data.
let context = CIContext()
let imageUrl = Bundle.main.url(forResource: "12mp", withExtension: "jpg")!
let data = try! Data(contentsOf: imageUrl)
let ciImage = CIImage(data: data)!
let start = CFAbsoluteTimeGetCurrent()
let data = context.jpegRepresentation(of: ciImage, colorSpace: context.workingColorSpace!)
print(data?.count)
print("Resize Completed: " + String(CFAbsoluteTimeGetCurrent() - start))
Running this code on an iPhone 16 Pro with different images produces these benchmarks:
12MP => 0.03s
24MP => 1.22s
48MP => 2.98s
I understand that processing time will increase with resolution but it doesn't seem linear. I have tried setting different CiContext options such as .useSoftwareRenderer: false but it has made no difference.
From profiling the process it looks like the JPEG decoding is the bottle neck. This is for a 48MP Image:
Is there any way this can be improved?
I've been working with MusicKit without enrolling for a developer account and I haven't run into any issues until I noticed nil on the SysteyMusicPlayer item for some songs and I don't understand why. Are some songs blocked from the framework? Or is it somehow a limitation to not having registered MusicKit to the bundle ID? I am planning on using MusicKit properly in prod and this is just a test app for a package I'm working on.
These are the nil songs which I got from the Discovery Station: https://music.apple.com/ca/album/okay/950816298?i=950816304

I am developing an iOS application that supports screen mirroring to Google TV (or Chromecast with Google TV). My goal is to mirror the iPhone/iPad screen in real time to a Google TV device.
What I Have Tried So Far
I have explored multiple approaches but haven't found a direct way to achieve low-latency screen mirroring. Here are some of my findings:
Google Cast SDK:
Google Cast SDK is primarily designed for casting media (videos, images, audio) rather than real-time mirroring. It supports custom receiver applications, but there are no direct APIs for full screen mirroring. Casting a recorded video is possible, but it introduces latency and is not real-time.
ReplayKit for Screen Capture:
RPScreenRecorder.shared().startCapture(handler: ...) allows capturing the iPhone screen as a video stream. However, sending this stream to Google TV in real time is a challenge. I could potentially encode the video as HLS and stream it, but the delay is significant.
RTSP/UDP Streaming:
Some third-party libraries support RTSP/UDP streaming for real-time screen sharing. Google TV does not natively support RTSP, making this approach difficult.
My Questions:
Is it possible to achieve real-time screen mirroring on Google TV using Google Cast SDK? Does Google TV support WebRTC or any low-latency streaming protocol that can be used from iOS? Are there any alternative approaches to mirror an iOS screen to Google TV with minimal latency? I would appreciate any guidance, code examples, or references to relevant documentation.
For some users in production, there's a high probability that after launching the App, using AVPlayer to play any local audio resources results in the following error. Restarting the App doesn't help.
issue:
[error: Error Domain=AVFoundationErrorDomain Code=-11800 "这项操作无法完成" UserInfo={NSLocalizedFailureReason=发生未知错误(24), NSLocalizedDescription=这项操作无法完成, NSUnderlyingError=0x30311f270 {Error Domain=NSPOSIXErrorDomain Code=24 "Too many open files"}}
I've checked the code, and there aren't actually multiple AVPlayers playing simultaneously. What could be causing this?
We are planning to develop an application using the Apple Music API.
We would like to design our system based on the details of the rate limits mentioned below and have a few questions:
https://developer.apple.com/documentation/applemusicapi/generating-developer-tokens#Request-Rate-Limiting
Regarding the Catalog API (/v1/catalog/*), we understand that server-side caching is enabled, making it less likely to reach the rate limit. Is this understanding correct? (Excluding the search API)
For APIs like the Library API (/v1/me/library/*), where responses vary by user, we assume they are more likely to reach the rate limit. Is this correct?
We plan to implement optimizations to minimize unnecessary API calls. Given this, would the current Music API be able to handle a significant increase in users? (Assuming a DAU of around 100,000 to 1,000,000)
If the API cannot support this scale, would it be allowed under Apple’s policy to cache responses from the Catalog API (/v1/catalog/*) via our proxy server to avoid hitting the rate limit?
The third question is the one we most want to confirm.
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.
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.
