Reply to Safe areas ignored after navigating a WebView/WebPage back in a NavigationStack
Are you able to reproduce this problem using the following sample? https://github.com/WebKit/WebKit/blob/cb619a3e3f54e69f1b46d36645b46606f9d12c9c/Tools/SwiftBrowser/Source/Views/ContentView.swift#L29 If you are then our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. If you post the Feedback number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports. If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

Reply to Issue when creating Bookmark with security scope on macOS 26 RC
First off, on the bug front, these issues should be resolved in macOS 26.1, which we released to beta last week (25B5042k). Please test on that beta, and if you find any problem, file a new bug and post the bug number back here. Are we actually talking about the same bug though? Yes, I believe so. Coe 256 seems to be an issue only for the root drive of exFAT. The issue here was actually introduced as part of a security fix (r.151029665) and it affected exFAT, some SMB mounts, and the / AFPS mount. In both cases, the high-level issue is the same (basically, stat wasn't returning what it expected), but the underlying cause was different. In the case of exFAT, the file system is basically “too simple, so it's basically returning a synthetic (invented) value because the file system doesn't really have an alternative it can provide. In the case of APFS, the issue is that the way that data and system volumes are merged means that you can get different values for the same object, depending

Issue when creating Bookmark with security scope on macOS 26 RC
With the RC version of macOS 26, an issue persists when you try to create a bookmark with security scope for the root folder /. This leads to an error The file couldn’t be opened.. However, you can create bookmark for /Applications, /System, /Users... This is quite annoying for one of my app because a user can create a cartography of his disk usage, and the access to the root folder / is the only way to do so! Is there a workaround? PS: reported the issue with ID FB20186406 let openPanel = NSOpenPanel() openPanel.canChooseDirectories = true openPanel.canChooseFiles = false openPanel.beginSheetModal(for: self.view.window!) { (result) in guard result == .OK, let folderURL = openPanel.url else { return } openPanel.close() do { let data = try folderURL.bookmarkData(options: .withSecurityScope, includingResourceValuesForKeys: nil, relativeTo: nil) print(Bookmark data was created for (folderURL.path)) } catch (let error) { print(Error creating bookmark for (folderURL.path), with error: (error.localizedDesc

Reply to How to turn off background extension effect in UISplitViewController?
@DTS Engineer What's the point of filing a bug report? Will it actually get fixed? I'm asking a serious question because I've already filed several iOS/iPadOS 26 bug reports related to UISplitViewController and UIKit. Several were reported against beta 1. Those bug reports include trivial sample apps and step-by-step instructions demonstrating the issue. None have been fixed as of iOS/iPadOS 26.0 GM. I also have several outstanding bug reports for broken functionality about UISearchController/UISearchBar under iOS/iPadOS 26. Again, several since beta 1. All include trivial test apps that demonstrate the issue. Again, none have been fixed. All of these outstanding issues are impacting my app. I'm very frustrated and disappointed. I'm sorry but I no longer have the ambition to file more bug reports that will never be fixed. I truly hope Apple gets back to the days of it just works. That era seems to be lost at the moment. Every year iOS and others are updated with lots of new features

Can’t change Primary Language — blocked by “for each version” even after deleting all CPPs (8 weeks, 10+ replies)
For ~8 weeks (10+ support replies) I’ve been unable to switch my app’s Primary Language from en-CA to en-US. App Store Connect shows: “Primary Locale couldn’t be saved because you must first provide all the required screenshots for each version in this language.” State: Default product page has complete iPhone + iPad screenshots for en-US and en-CA (live/approved). Issue began before any CPP existed; I have since removed all CPPs. Error persists, which suggests a stale/ghost CPP localization still being validated, or other issues. Questions: What does “for each version” precisely validate (live / in-prep / historical; default vs CPP)? Can deleted/never-approved CPPs still be validated, and how can they be purged? Anyone seen this after CPP removal—what fixed it? Happy to DM an Apple Staffer the case ID, a HAR of the failed save, and a short screen recording. Thanks! P.S. This has been open for ~8 weeks; I’m seeking an engineering-owned view to identify the specific unmet validator requirement or confirm a pro

Reply to tvOS 26 file corruption issues?
Hi - thanks for asking. My app will download a JSON file which contains a list of image urls which are downloaded and stored in the NSCachesDirectory. I understand the NSCachesDirectory can get deleted by the OS when the app is not running, so on subsequent launch, the app will check for the presence of these files in NSCachesDirectory and will redownload them if they are not available. This has worked pretty reliably in production for nearly two years. With tvOS 26, there are now inconsistent and sporadic instances when the app exhibits behavior as if these files have been deleted. ie. the images are either missing from the playlist page, or the app uses an onboard backup failsafe JSON file to populate a playlist with temporary data if it cannot find or load the JSON file. I suspect something is getting corrupted because once this issue occurs, the only way to get the app to perform normally again is to delete and reinstall the app. Simply relaunching the app will

Reply to Instructions for debugging recent macos kernel versions?
Hello Kevin, uname -v on my local system shows: Darwin Kernel Version 24.6.0: Mon Jul 14 11:30:30 PDT 2025; root:xnu-11417.140.69~1/RELEASE_ARM64_T6020 so I've been using T6020 as the platform when building the kernel. The corresponding xnu source is this tag https://github.com/apple-oss-distributions/xnu/tree/xnu-11417.140.69 and the KDK is KDK_15.6_24G84.kdk. sw_vers shows me: sw_vers ProductName: macOS ProductVersion: 15.6 BuildVersion: 24G84 So I think that's the right KDK version for this system. I'm guessing the XCode version doesn't matter for these experiments (as long as the build succeeds), but for the record, I'm on XCode 16.4: xcodebuild -version Xcode 16.4 Build version 16F6 Apart from the other build instructions, the primary one I use to generate a DEVELOPMENT variant of the kernel is: export KDK=/Library/Developer/KDKs/KDK_15.6_24G84.kdk make SDKROOT=macosx KDKROOT=$KDK BUILD_WERROR=0 BUILD_JSON_COMPILATION_DATABASE=1 TARGET_CONFIGS=DEVELOPMENT ARM64 T6020 and then to generate a (bootable) kex

Reply to Crash in libquic.dylib when app is backgrounded and issues an HTTP/3 request on iOS 26
Thanks for the crash report. We collected the crash logs from users online. So, does that mean that you can’t reproduce this yourself? Because in your original post you had “Reproduction Steps”, which suggests that this is something you can reproduce. Based on thread 8, it looks like you’re using a third-party crash reporter. That makes things difficult, as I explain in Implementing Your Own Crash Reporter. My advice is that you remove this crash reporter from your app and try to get a Apple crash report for this crash. Still, it’s probably worthwhile filing a bug with the info that you currently have. Please do that, and then post your bug number here.

Reply to URL Filter - blocked web page behaviour
I recommend that you report both of these via Feedback Assistant: Your first issue seems like a reasonable enhancement request. Your second issue seems like a bug. See Bug Reporting: How and Why? for general advice on how to file bugs effectively. Please post your bug numbers, just for the record.

Template Project Entity Overlapping and Sticking Issues
Hello, There are three issues I am running into with a default template project + additional minimal code changes: the Sphere_Left entity always overlaps the Sphere_Right entity. when I release the Sphere_Left entity, it does not remain sticking to the Sphere_Right entity when I release the Sphere_Left entity, it distances itself from the Sphere_Right entity When I manipulate the Sphere_Right entity, these above 3 issues do not occur: I get a correct and expected behavior. These issues are simple to replicate: Create a new project in XCode Choose visionOS -> App, then click Next Name your project, and leave all other options as defaults: Initial Scene: Window, Immersive Space Renderer: RealityKit, Immersive Space: Mixed, then click Next Save you project anywhere... Replace the entire ImmersiveView.swift file with the below code. Run. Try to manipulate the left sphere, you should get the same issues I mentioned above If you restart the project, and manipulate only the right sphere, you should get t

Reply to When is Apple ever going to release an updated screensaver Xcode template?
I can’t answer why questions. See tip 3 in Quinn’s Top Ten DevForums Tips. My advice here is that you file an enhancement request for a better screen saver API, one based on app extension technology. While we’ve seen similar requests many times before, a fresh bug report will allow you to express your needs in your own terms, and allow Apple engineering to gauge the level of demand. Please post your bug number, just for the record. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to Symbolicating kernel backtraces on Apple Silicon
I am unsure if there has been any progress in this area. But I needed to resolve a recent Tahoe panic, so chatgpt cobbled together this: https://gist.github.com/lundman/54e633a850e7623aae5adab38a39f464 If we are allowed to share?
