i0S26 issue with CarPlay
I just upgraded to iOS 26.0 Now when I use car play, the text messages do not show up, only the notification tone on my phone alarms. So now when I get texts while driving, I need to read my phone to read the text. I tried all the solutions within settings but this is a BIG DRAWBACK compared to the old iOS.

No calls history after downgrading from iOS 26
Hi, I made backup as Apple suggested. Then I updated to iOS 26 developer beta. Because it was slow and laggy I downgraded back to 18.5 with iTunes on MacBook. After restoring backup I cannot get history (recent calls) working. I tried to change region, airplane mode, reset network settings, change date and time, reboot (3x). Basically I guess I tried everything I cloud find online. Still call history doesn't work. Is there any fix for this? Before restoring backup I reinstalled everything in restore mode.

WWDC26 beta cellular issues
So recently, last week, ive updated to the Dev Beta of ios 26. This began the very issue of my cellular data. I woke up to a warning symbol where my cellular bars should be, telling me there was something wrong with my antenna or carrier when in reality there was no problem with any of those problems and took up about 53% of my storage. This is absolutely insane and unacceptable.

3rd party camera hardware with API
I hope questions about third party APIs are allowed. If not I guess a delete is in order. That said.... I am looking to do an app for dog owners, trainers and enterprises such as shelters & boarding, and a couple of features require access to one or more cameras in real time. So I have been looking for hardware that provides an API and coming up empty. So far as I can tell none of the major pet cam companies, like Furbo, Petcube or Eufy. Even security cameras like the TP-Link Tapo doesn't seem to. Am I just failing epically in my search formulation, or are all these companies playing the printer game and selling the camera cheap and making all their money in the monthly subscription to actually be able to use the hardware, and keeping that to themselves? And, can anyone recommend decent to good third party hardware that does provide a Swift API? Or am I better off just targeting the use of iPhone & iPad and Mac cameras? It's not ideal, but it's better than nothing.

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!

USB Audio Input Blocked When Screen Mirroring via AirPlay
Hello Apple Developers, I am experiencing an issue where USB audio input (e.g., external USB microphone) is blocked when using AirPlay screen mirroring from my iPhone to a Mac or Apple TV. However, the built-in microphone continues to work without any problem. Issue Details: I am using an iPhone 15 (or latest device) running iOS [your iOS version]. I connect a USB audio interface/microphone via a USB-C adapter or Lightning adapter. The USB microphone works perfectly for audio input before starting AirPlay. The moment I enable AirPlay screen mirroring, the USB microphone stops working, and it disappears from available audio input sources. The built-in microphone continues to function, but I cannot use the USB microphone while mirroring. When I stop screen mirroring, the USB microphone immediately becomes available again. Expected Behavior: I would expect iOS to allow me to continue using an external USB microphone while mirroring my screen, just like it allows the built-in microphone to work. Questions: Is this an intentional restriction in iOS? Is there any workaround to enable USB audio input while using AirPlay screen mirroring? Is there a way to request a feature or configuration option to allow external USB microphones during AirPlay? I appreciate any insights or guidance from the Apple team or fellow developers. Thanks in advance! Best regards,

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 ?

macOS 26 Beta 1 on MacPro7,1 – WindowServer crash when opening Finder
I’m running macOS 26 Beta 1 (build 25A5279m) on a 2019 Mac Pro (MacPro7,1) with a single 4K display connected via HDMI. Whenever I attempt to launch Finder, WindowServer immediately aborts and the machine reboots. Crash details: Process: WindowServer (PID 1441) Exception: EXC_CRASH (SIGABRT) triggered in thread 0 (ws_main_thread) Termination Reason: Abort trap: 6 Backtrace highlights: CA::OGL::MetalContext::draw(MTLPrimitiveType, …) hits an internal __assert_rtn in libsystem_c.dylib Subsequent calls all stem from QuartzCore’s OpenGL/Metal bridge (CA::OGL::render_layers, LayerNode::apply, etc.) Related threads: Thread 2 (com.apple.coreanimation.render-server) idle in mach_msg_overwrite Thread 1 shows AmbientDisplay and ColorSync callbacks running Hardware/Software: MacPro7,1 (2019) macOS 26.0 Beta 1 (25A5279m) 4K monitor via HDMI System Integrity Protection enabled What I’ve tried so far: Safe-boot (crash still occurs) Switching display profiles in System Settings → Displays → Color (no effect) Happy to provide any additional logs or verbose console output. Let me know if there’s any other data that would help diagnose the Metal/OpenGL integration issue in this beta.

Question regarding ethernet over USB-C
Hello, I have a question regarding the ethernet-over-USB-C stack within iOS/iPadOS. It seems that when manually assigning an IP on this interface within iOS, the IP is stored. Therefore, when disconnecting (the USB-C cable) and reconnecting to another device for a subsequent ethernet connection, the iOS device will always default to the previously assigned IP address (obviously, this isn't the case if the other end is a DHCP server). So, within the iPhone's Ethernet-over-USB-C driver, I was curious if iOS just keeps the assignment based on the MAC of the local USB-C interface, or is stored information tied to some other identifier? Is there a way to override this behavior? Thank you

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?

iPhone 13 Pro stuck in DFU/Recovery after failed flash.
Installed the iOS 26 Beta on my iPhone 13 Pro last night, hated it. I wasn't aware that there is a supported way of restoring back to iOS18.5, so I (foolishly) opted to flash the iOS18.5 ispw file onto my device using a 3rd party tool. Now, my device is stuck in a state between. Unable to flash, unable to use itunes to restore, randomly gives error codes during restoration attempts. Worries my device may be lost permanently! Please advise.
