Reply to Test my app without ADP membership
The OP wants to use the FamilyControl entitlement. The request page requires a purchased membership to access. I'm not familiar with this feature, but it doesn't sound like something that a developer could just turn on for debug builds. Maybe you could in the simulator? From said request page, it looks like one would have to have the app ready first and then request the entitlement. And most importantly, it's just a request. Judging from other people's experiences, these requests can take from 2 days to 4 months to be accepted, and possibly rejected.

Reply to Background service on MacOS
In the context of macOS when we say application (or app) we mean something that’s double clickable in the Finder, shows up in the Dock, has a menu bar, and so on. Your product doesn’t do that, so it’s not an app. How do you want to managed install and uninstall? I've made this Rust application being packed in to a PKG installer, which installs a valid terracotta.app bundle to Application dir. Therefore, Users can run this application by cdouble clicking the icon in Finder and it will show up in the dock. So, THIS IS A APPLICATION. What is the desired lifecycle of your program? I want to make my program being runned in background ONLY AFTER users manually launch the application. Therefore, their won't be much performance waste when my application hasn't being launched since the computer start. And the application will exit and no longer running in the background if certain condition is met, for example, there's no traffic for the application on the port-forward feature. (Of course, there will be a pop

It sounds like you’re hitting a local network privacy limit. See TN3179 Understanding local network privacy for more background on that. If so, I recommend that you retest with the iOS 18.6 release candidate. It contains a critical local network privacy fix.

Execution breakpoint when trying to play a music library file with AVAudioEngine
Hi all, I'm working on an audio visualizer app that plays files from the user's music library utilizing MediaPlayer and AVAudioEngine. I'm working on getting the music library functionality working before the visualizer aspect. After setting up the engine for file playback, my app inexplicably crashes with an EXC_BREAKPOINT with code = 1. Usually this means I'm unwrapping a nil value, but I think I'm handling the optionals correctly with guard statements. I'm not able to pinpoint where it's crashing. I think it's either in the play function or the setupAudioEngine function. I removed the processAudioBuffer function and my code still crashes the same way, so it's not that. The device that I'm testing this on is running iOS 26 beta 3, although my app is designed for iOS 18 and above. After commenting out code, it seems that the app crashes at the scheduleFile call in the play function, but I'm not fully sure. Here is the setupAudioEngine function: private func setupAudioEngine() { do { try AVAudioSessi

Strange behavior of Speakerbox (or CallKit) with headset operation
I've run Speakerbox(https://docs-assets.developer.apple.com/published/8e99045a90e2/MakingAndReceivingVoIPCallsWithCallKit.zip) to check the behavior of CallKit. When there was one active call and one on hold and another call was received, the behavior was defferent depending on whether I operated it from a headset or not. No headset or operated from CallKit screen When End & Accept tapped: the active call is hung up, and the received call is answered. When End Held & Accept tapped: the held call is hung up, the active call is held, and the received call is answered. Operated from headset Answer opeation cannot be performed for unknown reasons Disconnect operation caused that all calls other than the one on hold are hung up and the held call is unheld. Hold operation caused that the active call is held and the received call is answered. (Strangely, there are two held calls.) And when I toggle calls at this time, one of the two on hold is hung up for unknown reasons. I tried changing the settings of CXP

Reply to Strange behavior of Speakerbox (or CallKit) with headset operation
I've run Speakerbox(https://docs-assets.developer.apple.com/published/ 8e99045a90e2/MakingAndReceivingVoIPCallsWithCallKit.zip) to check the behavior of CallKit. When there was one active call and one on hold and another call was received, the behavior was different depending on whether I operated it from a headset or not. SO, the first thing to understand is that what CallKit is actually reacting to are specific commands being sent through the HFP (Hand Free Profile), the Bluetooth profile headsets (meaning, devices which can both play and record audio) use. The HFP profile is large and complicated enough that there can be significant differences in the commands headsets send. The behavior of most popular headsets has consolidated around a common set of behavior (which is why this works at all), but if you're testing with older or uncommon headsets, you may see weird behavior. *Note that age isn't reliable here because there are many headsets which are actually still using very old chips/implementat

Multiple Videos' Sound Overlapping Issue in Photos
Feedback:
 When playing videos in the Photos app, the sound doesn’t stop automatically when swiping to the next video. For example: Open a video—sound plays only after manually enabling it. Swipe to the second video—the first video’s sound continues playing. Swipe to the third video—both previous videos’ sounds keep playing, overlapping with the current video’s audio. Problem:
 Users must manually go back and pause each previous video to stop the sounds, otherwise, they loop indefinitely. This creates a frustrating and confusing experience. Request: 
Please fix this issue by automatically stopping the audio of previous videos when swiping to a new one.

IPCAUClient.cpp:139 IPCAUClient: can't connect to server (-66748) <0x104309130>
When using the AVSpeechSynthesizer() , I get an error after a couple of seconds :IPCAUClient.cpp:139 IPCAUClient: can't connect to server (-66748) <0x104309130>, and then it speaks the text. The second time I call speak, there is no delay and error and it speaks immediately. Where does this error and delay come from and how can I resolve it? Intialization code: self.audioSession = AVAudioSession.sharedInstance() // 2) handle audio session first, before trying to read the text do { try audioSession.setCategory(.playback, mode: .voicePrompt, options: .duckOthers) try audioSession.setActive(false) } catch let error { Logger.model.debug(❓(error.localizedDescription)) } speechSynthesizer = AVSpeechSynthesizer() speechSynthesizer.usesApplicationAudioSession = true Speak code: let utterance = AVSpeechUtterance(string: text) utterance.preUtteranceDelay = 0.1 utterance.rate = 0.5 utterance.pitchMultiplier = 0.75 utterance.prefersAssistiveTechnologySettings = false self.speechSynthesizer.speak(utterance)

iOS 26 Beta Personal Voice bug affecting AVSpeechSynthesizer
I have sent in a feedback report (FB18222398) but I have no idea if anyone has looked at it. I know from past experiences that Apple devs do look at these forums. This applies to each of the betas, 1, 2 and 3. I have created a new Personal Voice with each beta. I create a personal voice in English. When it's done processing, I tap Preview and it says in English what is expected. But after some time, an hour or a day, the language of the voice file changes languages and no longer works properly. If I press Preview it is no longer intelligible. I have a text to speech app and initially the created voice works but then when the language of the file changes, it no longer works. I have run an app on my iphone through Xcode that prints to the console the voices installed on the device with the language. Currently this is the voice file: Voice Identifier: com.apple.speech.personalvoice.AAA9C6F2-9125-475F-BA2F-22C63274991D Language: es-MX and on a second device the same personal voice is in a different language: Voic

with beta 4 out, i deleted the personal voice created with beta 3, restarted my iphone and updated to ios 26 beta 4. created a new personal voice in english. when i press preview in the settings app it doesn't say anything. in my text to speech app it doesn't use the personal voice created. it uses an asian sounding voice for english. i ran the voices app i created in xcode and got the following results for the personal voice created: Voice Identifier: com.apple.speech.personalvoice.B3D041B5-D3F1-49F5-8466-0284FE9AC342 Language: zh-CN issue persists. i'm updating feedback submission.

AlarmKit authorizationState is always notDetermined even if permission has been previously granted
I am using AlarmKit in my app. When I access: AlarmManager.shared.authorizationState It always returns notDetermined, even when I have previously granted the app permission to use alarms via: try await AlarmManager.shared.requestAuthorization() Calling this API again grants me the permission though, without showing the permission prompt to the user. This sounds like a bug - if the permission has been granted, accessing authorizationState should return .authorized. It shouldn't require me to call requestAuthorization() again to update the authorization status again? Environment: iOS 26 beta 3 Xcode 26 beta 3
