Is there an errors with SpatialAudioCLI?
Hi, everyone, I downloaded the source code EditingSpatialAudioWithAnAudioMix.zip from https://developer.apple.com/documentation/Cinematic/editing-spatial-audio-with-an-audio-mix, when I carried out one of the actions named process in command line the program crashed!! Form the source code, I found that the value of componentType is set to kAudioUnitType_FormatConverter: // The actual `AudioUnit`. public var auAudioMix = AVAudioUnitEffect() init() { // Generate a component description for the audio unit. let componentDescription = AudioComponentDescription( componentType: kAudioUnitType_FormatConverter, componentSubType: kAudioUnitSubType_AUAudioMix, componentManufacturer: kAudioUnitManufacturer_Apple, componentFlags: 0, componentFlagsMask: 0) auAudioMix=AVAudioUnitEffect(audioComponentDescription: componentDescription) } But in the document from https://developer.apple.com/documentation/avfaudio/avaudiouniteffect/init(audiocomponentdescription:), it seems that componentType can not

Testing Age Assurance in Sandbox Failed
According to Apple's documentation at https://developer.apple.com/documentation/storekit/testing-age-assurance-in-sandbox?language=objc, the testing steps and expected responses are outlined as follows: Test app consent revocation To test the notification when a parent or guardian revokes access to your app on behalf of their child, follow these steps: Start with a Sandbox account. From the Age Assurance settings, tap Revoke App Consent. Enter your app’s Bundle ID (for example, com.example.bundle). Tap Revoke Consent to simulate the revocation. Confirm that the system displays “Notification Triggered” with the message “A notification will be sent to the developer server soon.” I followed the steps exactly as described above, but during the fifth step, instead of seeing the prompt A notification will be sent to the developer server soon, a pop-up dialog with only a confirmation button appeared. After clicking it, there was no further response, and our server did not receive any notification (neither f

Reply to Wakes (CalendarDate), although related UI settings are off
Are you build a product for macOS where this is relevant? If so, can you explain more about the background to that. If not, I suspect that the Apple Developer Forums aren’t the right place for you, and I encourage you to pop on over to Apple Support Community, run by Apple Support.

Swift Playground preview issues
I am a high school teacher from China, currently teaching programming courses at my school. Several issues are preventing the course from being completed on schedule. As shown in the image, there are two problems: The preview issue has existed since updating to the latest software and system version; I don't know how to resolve it. After renaming a Swift file, this window keeps popping up, even after closing it. This problem didn't exist last year. How can I fix this? Thank you for your reply! 我是一名来自中国的高中教师,目前在学校开设编程课程,目前有几个问题导致课程无法如期完成。如图所示,存在两个问题: 一、自从更新了最新版本的软件和系统后,预览问题就存在,不知该如何处理 二、swift文件重命名后,一直跳出来这个窗口,关掉以后还是跳出来 去年的时候还没有存在这样的问题,请问我该如何处理,感谢您的回复!

[Core Bluetooth]The Application Playing a Notification Tone (AVAudioPlayer, System sounds) Should Automatically Route Audio to the Connected BLE accessory which uses HFP Profile
The iOS application is a Central Manager connected to a Bluetooth Low Energy (BLE) accessory that utilizes the Hands-Free Profile (HFP). When the application plays a notification tone (using AVAudioPlayer or System Sounds), the audio is incorrectly routed to the device's internal speaker instead of the active HFP headset. How do we programmatically ensure that these notification tones are automatically and reliably routed to the connected HFP headset

Reply to Spatial Audio on iOS 18 don't work as inteneded
For completeness, this is the view I'm experimenting with: import AVFoundation import SwiftUI class EngineerPlayer { let audioEngine = AVAudioEngine() let playerNode = AVAudioPlayerNode() let environmentNode = AVAudioEnvironmentNode() init(_ url: URL) throws { let audioFile = try AVAudioFile(forReading: url) let mono = AVAudioFormat(standardFormatWithSampleRate: audioFile.processingFormat.sampleRate, channels: 1) let stereo = AVAudioFormat(standardFormatWithSampleRate: audioFile.processingFormat.sampleRate, channels: 2) audioEngine.attach(playerNode) audioEngine.attach(environmentNode) audioEngine.connect(playerNode, to: environmentNode, format: mono) audioEngine.connect(environmentNode, to: audioEngine.mainMixerNode, format: stereo) audioEngine.prepare() try audioEngine.start() environmentNode.renderingAlgorithm = .HRTFHQ playerNode.pointSourceInHeadMode = .mono playerNode.position = AVAudio3DPoint(x: 0, y: 2, z: 10) playerNode.scheduleFile(audioFile, at: nil, completionHandler: nil) } func updatePosition(_

Reply to "Signing certificate" and post-installation assignment fail due to IOPCIPrimaryMatch
So, let me start with the causes of these failures: But when I do, the signing certificate status in Xcode shows as failed. Why is that? This post has more detail, but in basic terms, your app’s signing is created from two components: Your Entitlement.plist -> This is used to create the actual code-signature attached to your app bundle. The provisioning profile -> This is a file that we've signed and which is then embedded inside your app’s bundle. (Note: not all signed apps have/need one of these, but all DEXT do). The system validates the entitlement by comparing the entitlement values contained in those two files (your app’s code signature and its embedded provisioning profile). That's why the profile (#2) is signed by us - it proves we want your app to have the entitlement. Xcode checks that your app is properly signed by comparing the data in those values to ensure that they match, creating this failure when they don't match. What I wanted to convey in my previous post was that I think I should inc

Adopt watchface background for complication
On the California watchface (white) there are two complication slots. The upper one is seemingly not a standard slot and limited to a few Apple-owned apps (Calender, Time, …). It adopts the (default white) background of the watchface, so the date is neatly and cleanly displayed on the watchface backdrop. The other lower circular complication makes up for a fat black bubble now on the clean face, which doesn‘t look too pretty (of course depending on the complication…). I would like to create a complication with rather minimalistic content, and it would look great if it could also share the white background and just produce that content on top of it. While the documentation sounds like it would be possible to make the widget background adopt the context colors (which I would understand as using the same background color), for the life of me I can‘t get anything else than black for the circle. Has anyone achieved that? How would I do that? (Image below shows the temperature widget…mine would have way le

Reply to How to check if a sandboxed app already has the access permission to a URL
@Etresoft You can use the isReadable value from URLResourceValues. Thank you. This is exactly the API I was looking for. However, it sounds like you're not approaching this from the right direction. I'm not trying to open random files...; I just want to use it to prompt the user to obtain access permissions if they don't have them for the file they tried to open (the file linked by an alias).

Reply to CLLocationManager didVisit no longer invoked reliably after iOS 26 updates
This sounds like a regression our engineering teams need to investigate this issue, as this might indicate an issue with iOS 26.x We'd greatly appreciate it if you could open a bug report, include any logs and sample code or models that reproduce the issue, and post the FB number here once you do. We would also like a diagnostic log. It would be very helpful if you could please go to https://developer.apple.com/bug-reporting/profiles-and-logs/ and follow the instructions for Location Services for iOS to install a logging profile on your device. Then reproduce the issue, and follow the instructions at the above link to create a sysdiagnose. And attach that to the Feedback report as well. Bug Reporting: How and Why? has tips on creating a successful bug report. Important: For feedback related to a specific framework or API, select Developer Technologies & SDKs as your Topic, then select the specific technology and relevant OS. For feedback related to Xcode, App Store Connect, or other developer too

Need to fix audio auto-play for iPhone mobile users (specifically on safari and chrome)
Hi! My team and I are developing an education platform. One of our features is a auto-play flashcard feature where users can listen to their flashcards hands free. We are having an issue where the autoplay wont work for users with iPhone's. I think the rule is that user's are supposed to give consent to the auto-play. We do make the user hit play before it starts so that should be the constent but it's still not working. Anyone have ideas?

Core audio for using to record Multitrack audio.
Hello, I’ve looked at a video and have tons of research and I’m trying to see if there is a way core audio can be created in Xcode as an audio device? “keep in mind” I am totally new to apple’s developer forums and I do not know anything about Xcode nor on how to create an audio device of coreaudio on a Mac since there’s a lot stuff that has do with coding. Nor am I good with that type of technology.
