Lost 32 digit ASk
I received my approval for FairPlay Streaming (FPS) and was getting things organized and then my computer crashed. So... Yes, I lost the 32 digit Account Security Key (ASk) that I was warned not to lose repeatedly... I understand that I can't query apple for the existing ASk. I don't see where I can delete the existing cert to request another one. So I assume I'll need to start from scratch either with another FPS approval process. Can someone please direct me on next steps for this boneheaded situation. Thank you

safeArea access in XCode 26, iOS 26
Hi. In my project, I use the following property to access the safe area via UIApplication: UIApplication .shared .connectedScenes .flatMap { ($0 as? UIWindowScene)?.windows ?? [] } .first { $0.isKeyWindow }?.safeAreaInsets However, in Xcode 26 and iOS 26, this no longer works, and in some cases the app crashes. Views that rely on this property stop behaving as expected. For example, if it’s a sheet, it does not appear. The same app built with Xcode 16 and distributed via TestFlight runs on iOS 26 without any issues. What is the correct and safe way to obtain safeAreaInsets outside of a View now?

Reply to app crashes
launch failed, RBSProcessExitContext voluntary I assume that you've discovered this message in the system log. Before going further, double check that it pertains to your app's process so that you don't go chasing down something that doesn't pertain to your app. Now, assuming that you've confirmed that, voluntary is the key word in that message — the most straight-forward explanation for when this happens is that a code path run by your app chose to call exit, ending your app’s process gracefully. This isn’t a crash, so there is no crash report that would backtrace right to the code path that made this call. As a starting point to locating any code paths in your app that call exit() directly, search your app’s entire source code for any calls to the system exit function, including any third-party libraries you use, and see what turns up. I sometimes like to use grep to find issues like these, should they turn up in unexpected corners, or potentially inside pre-compiled libraries that you can

Crash when trying to get originatingRecipient
According to the documentation (https://developer.apple.com/documentation/avfoundation/avcontentkeyrequest/originatingrecipient?changes=_3&language=objc), starting with ios 18.4, I can get AVContentKeyRecipient from AVContentKeyRequest. But when I try to get it, I get a crash. What could be the issue? I want to note that I add the asset to the AVContentKeySession using the addContentKeyRecipient method (https://developer.apple.com/documentation/avfoundation/avcontentkeysession/addcontentkeyrecipient(_:)?changes=_3&language=objc).

You mean that the compiler crashes? If so, that’s probably something best addressed over in Swift Forums > Using Swift. And speaking generally, to improve your chances of getting traction: Be clear about what version of the compiler you’re testing with. Isolate the code into a small test project that reproduces the issue. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Spatial Audio on Mac - When and how to render using Audio Units?
I'm working on adding Spatial Audio support to a game on the Mac. I'm looking at the SpatialAudioRenderer sample but having some issues. It's unclear to me when a device is compatible with Spatial Audio and when I should attempt to render Spatial Audio. There is no property that I can find on the Mac that advertises Spatial Audio compatibility on a device. The sample crashes when the output device is a USB device. This includes the Apple Studio Display. The Apple Studio Display is supposed to be capable of rendering Spatial Audio. The device doesn't work with the sample - do I still need to render down the 7.1.4 source on this device? The sample always renders down to Stereo, but the Apple Studio Display is not a Stereo device. I'm a bit confused by the sample and when/how I should configure the mixing unit.

This is a successor to: https://developer.apple.com/forums/thread/814231 I went into a slightly different direction. I generated more AI slop that use NSLock.

Reply to Crash/Exception thrown in UITableView initialization stack
Thanks for the post. I love crash files and you came to the correct place as they are better developers here that can help you with a crash. The interesting issue is that is crashing on swift core lib? However will be a great idea you follow this recommendations to post a crash file with all the information that can help them figure it out. Kindly submit a comprehensive crash report, adhering to the guidelines outlined in Posting a Crash Report. https://developer.apple.com/forums/thread/688669 Have you test it with iOS 26.2? In my modest opinion and without code nor much besides the header, the crash you're encountering, suggests that there might be an attempt to access memory that's either invalid or no longer valid. Ensure that the object or table or table items managing the isn't being deallocated prematurely. Any strong reference cycles or unintentional over-release could lead to accessing a dangling pointer.

Help with visionOS pushWindow issues requested
I first started using the SwiftUI pushWindow API in visionOS 26.2, and I've reported several bugs I discovered, listed below. Under certain circumstances, pushed window relationships may break, and this behavior affects all other apps, not just the app that caused the problem, until the next device reboot. In other cases, the system may crash and restart. (FB21287011) When a window presented with pushWindow is dismissed, its parent window reappears in the wrong location (FB21294645) Pinning a pushed window to a wall breaks pushWindow for all other apps on the system (FB21594646) pushWindow interacts poorly with the window bar close app option (FB21652261) If a window locked to a wall calls pushWindow, the original window becomes unlocked (FB21652271) If a window locked in place calls pushWindow and the pushed window is closed, the system freezes (FB21828413) pushWindow, UIApplication.open, and a dismissed immersive space result in multiple failures that require a device reboot (FB21840747) visionOS r

Reply to Launchscreen issues on iPadOS 26
I can confirm there is something crashing my Apps that only have Launchscreen storyboards. I use Autoresizing and not Autolayout. And guys please, make a real effort to build a Launchscreen component in SwiftUI. It makes no sense in 2026, always ten years after and we still have a storyboard file messing/crashing our Apps in Swift.

Assert error breaking previews
A foundation models bug I keep running into when in the preview phase of the testing. The error never seems to occur or break the app when I am testing on the simulator or on a device but sometimes I am running into this error when in a longer session while being in preview. The error breaks the preview and crashes it and the waring on it is labeled as : Assert in LanguageModelFeedback.swift This is something I keep running into, where I have been using foundation models for my project
