In rare VoIP calls, B can’t hear A, but A can hear B — audio input issue on iOS?
Hi everyone, We’re seeing a rare but frustrating issue in our iOS VoIP app and would appreciate any advice. What’s happening: In some VoIP calls between two users (let’s say A and B), B can’t hear A’s voice, but A can still hear B just fine. It doesn’t happen often, but once it does, the issue persists until the device is restarted. Users who experience this issue typically have other voice or conferencing apps installed and actively use them. They report that when our app runs into this problem, those other apps continue to work normally. ⸻ What we’ve ruled out: • AVAudioSession has microphone permission, and audio input works under normal conditions • Network conditions are stable • App-side logic seems solid — the issue occurs extremely rarely (e.g., 1 out of several thousand calls), making it unlikely to be caused by a consistent bug in our call flow ⸻ What we’ve tried to fix it (all ineffective): Restarting the call — no effect Force-quitting and relaunching the app — no effect Toggling Bluetooth: disconnecting and reconnecting audio route, or switching back to built-in mic — no effect Replugging wired headphones or switching to the default iPhone audio input — no effect ⸻ What actually works (so far): • Restarting the device — this is the only action that reliably fixes the issue ⸻ What we’re looking for help with: 1. Does this sound like an iOS-level AVAudioSession routing or audio stack issue? 2. Is there any way to recover from this state without rebooting the device — either through iOS system settings or programmatically? 3. Are there any known audio routing or input bugs in iOS that match this behavior? Thanks in advance — any suggestions or pointers would be greatly appreciated!

Making music….
Maybe a bit of a simplistic question, but…. Best ways to create music - programmatically - within an app? I have a few small, simple games that I would like to add some background music to. I’ve fiddled with AVAudio, SKAudio, and now AudioKit. I’m just not quite finding the holy grail of music generation. I don’t know if it’s more technique or tool. So I thought I’d hit up the pool of minds here for some suggestions…?

Problem with deleting the MinimaList app
A question from an ordinary user for developers: The essence of the problem: I installed the To Do List by MinimaList app on both my MacBook and iPhone. After installing it, I decided not to use it and deleted the application. https://apps.apple.com/us/app/minimalist-to-do-list-widget/id993066159 However, it turned out that not everything was removed. Specifically: • In the “Allow Others to Find Me” section on both my MacBook and iPhone, these apps still appear. No matter what I do—whether I delete or clear them—they continue to be displayed there. • This app continues to appear in the section located at: Settings → Apple ID → iCloud → Stored in iCloud → See All → Allow Finding Me – To Do List and one more item. • It cannot be deleted. • It won’t delete on my MacBook, and it won’t delete on my iPhone. • It also appeared in iCloud itself under the Email Search section. P.S. The official Apple support (without violating any internal regulations) advised me to post on the forum to get in touch with Apple developers. In hope, I am posting this question here.

Unexpected high mobile data usage when travelling in Europe using an ESIM on iPhone 16 Pro Max
The iPhone mobile data usage skyrocketed to use 1GB per day whereas I am normally a 5GB a month data user. the culprit was Apple System Services General there is currently no iPhone functionality to turn off System Services Genera. the solution was to block updates.cdn-apple.com using data sniffer called Proxyman. Tip hat to the person who posted “High mobile data usage on iOS 18 and how to solve it” on Reddit.com This is something apple developers maybe should look at

iOS 26 : iPhone 16 Pro not charging via USB-C
Hello, I installed iOS 26 beta 1 yesterday when it came off but now, when I plug my iPhone, it just do nothing. I can charge it via the induction charger but I can't via USB-C port. The other way I can charge it is by turning my iPhone off and plugging it so it starts and then it charges via USB-C Port even when it starts. The thing is that when I unplug the cable and try to plug it back in, it doesn't charge anymore... I tried to put the restore mode (with the Mac and the cable on the screen) and even the DFU Mode but the iPhone is not detected by my Macbook and it's the same thing for my Windows PC : not detected... I also tried to erase the settings and content but same issue... Not charging Apple Store can do nothing because it's a dev beta... Am I the only one to have that issue ?

CarPlay Turn-By-Turn Entitlements
Hello Devs, I wanted to bring this up to display the frustration that I have obtaining the CarPlay entitlements. First and foremost they don't give you a set timeline and there is no contact number to speak to someone about this. When you call developer support they go on and say it is a different department. There is an email but all I have received is an automated response back to me. Has anyone received the navigation entitlements and if so what was the timeline of you receiving it?

CoreAudio: Audio Output Device Stopped Error since macOS 15
Hello! I used the Apple CA Playthrough example code that pipes audio between devices. It uses AudioUnit callbacks to pipe the input to an output device, and I created a system equalizer with it - however users reported it stopped working in macOS 15. I am getting the error HALPlugIn.cpp:552 HALPlugIn::DeviceGetCurrentTime: got an error from the plug-in routine, Error: 1937010544 (stop) for the output device and no sound coming out of the speakers. The error only occurs when using a virtual device as an input, not using the microphone. First I thought the problem was in the loopback driver, but it also does not work with other loopback drivers like Blackhole. STEPS TO REPRODUCE Install a virtual device, for example "brew install blackhole-2ch" and run the CAPlayThrough example code (you need to add Mic Permission in the info.plist). Then set your system audio output to the virtual device, select the device as input in CAPlayThrough and hit start. You should see the error in console. My question: What did change in macOS 15 that could cause this? Is it something with the new permission handling maybe?

Pilot Comms/headsets
Based a quick research, comfort and fit, noise cancellation issues and durability seems to be the most consistent issues with pilot headsets. I wouldn’t say there is a problem here, because you can easily throw out the faulty headset and spend another $1000 on a new one. However, what if apple can profit by introducing their version of pilot headsets? Besides, most airlines use Apple iPads for Navigation, crew scheduling etc. Make it a one stop shop. Apple already has the framework for music headsets, why not use it as a base for pilot headsets? Disrupt an already stagnant market and give pilots a great alternative. Tap into the interests of a new generation of pilots again most which already uses Apple products. Come up with a new fresh look of ‘pilot comms.’ A good idea is to pitch to the GA (general aviation) industry maybe include Apple headsets with the purchase of a new aircraft.

How can I create a shortcut to toggle macro control in iPhone settings?
I’d like to create a button on my iPhone Home Screen that changes settings if I am using an external lens mounted to my phone. This is what I have along with notes on what I hope to do. But it does not work. I am only able to open either the camera settings or the camera preserve settings but nothing will toggle macro controls. There is an additional step within the camera app as well but it can be skipped for brevity. Name: Telephoto and macro lenses Check if macro settings are already enabled or not. (Settings > Camera > Macro Control toggle) as well as (Settings > Camera > Preserve Settings > Macro Control toggle) Non-working shortcut code: Verification question: "Are you using an external lens?" If yes, Notification: "Turning on Macro Control and preserve settings for macro control." (Run below immediately) prefs:root=CAMERA&path=Turn%20On%20Macro_Control And prefs:root=CAMERA&path=CameraPreserveSettingsSwitch&path=Turn%20On%20Macro_Control If no, Notification: "Turning off Macro Control and Preserve Settings for macro control." (Run below immediately) prefs:root=CAMERA&path=Turn%20Off%20Macro_Control And prefs:root=CAMERA&path=CameraPreserveSettingsSwitch&path=Turn%20Off%20Macro_Control
