Reply to Xcode 26.1 RC issue
Same problem here with ReportCrash. But I see it even with the iOS 26.0 Simulator. It started in Xcode 26.1. I didn't have this issue in Xcode 26.0. Reported yesterday via Feedback Assistant: FB20918609 I can't work like this. My MacBook is getting extremely hot in seconds.

Reply to Installer packages are failing to install on macOS26.1
Is this only affecting new versions of your product? Or are you seeing it with old versions? That is, if you take a version of your product built, say, 6 months ago and try to install it on macOS 26.0 and macOS 26.1, do you still see it work on the former and fail on the latter? If so, you should file a bug about that, making sure to include: A copy of the installer package A sysdiagnose log taken shortly after seeing the failure Once you’re done, please post your bug number.

Reply to Notary service down again?
When the notary service actually goes down, DevForums tends to light up with complaints. I suspect that this issue in something specific to your product. Looking at your older thread, it shows that notary responded, but with an error complaining about the format of your submission. Is that case again now? If so, please post your notary log again and I’ll see what I can figured out. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to Provisioning profile entitlements
[quote='806186021, binarytwist, /thread/806186, /profile/binarytwist'] How can I get a provisioning profile that only has the entitlements that I actually need? [/quote] You shouldn’t need to do this. The entitlements in a provisioning profile act as an allowlist. For an in-depth explanation of that, see TN3125 Inside Code Signing: Provisioning Profiles. When you enable the NE capability on an App ID and generate a profile for that App ID, the Developer website includes all NE types supported by the target platform. Hence the presence of url-filter-provider value. However, this is just an allowlist. The entitlements you claim are those in your code signature, and that’s what the Validate App should be checking. [quote='806186021, binarytwist, /thread/806186, /profile/binarytwist'] My entitlement file has [/quote] Your .entitlements file isn’t the source of truth here. It’s source code that acts as an input to the Xcode build system. So you need to check the entitlements on your built binary. Do this: In the X

Reply to Correct SwiftData Concurrency Logic for UI and Extensions
Hi Ziqiao, Your previous guidance to use a ModelActor and PersistentIdentifiers has successfully resolved all my data race crashes. However, I'm left with one persistent UI-level race condition, specifically related to deletion. My View Structure My setup is a standard master-detail pattern, which on iPhone (where I'm seeing this bug) acts like a NavigationStack: ScheduleView (Master): Uses @Query to fetch and display all events in a List. Each row is a NavigationLink. This view also has a swipe-to-delete action on its rows. EventDetailsView (Detail): The destination of the NavigationLink. It contains a Delete button. The Problem: A dismiss() vs. @Query Race When I tap the Delete button in EventDetailsView, I call my actor (e.g., await databaseManager.deleteEvent(id: event.persistentModelID)) and then immediately call dismiss() to pop the view. The Bug: When the app returns to ScheduleView, the row for the just-deleted event is still visibly active in the list for at least 5 seconds before it finally

Reply to UIManagedDocument and Swift 6
iOS 26.1 is released, iOS 26.2 beta appeared, but no signs that UIManagedDocument loses @MainActor. Does anybody have the same concern? Anybody uses UIManagedDocument and wants to transition to Swift 6? Or, perhaps, already use it?

UIManagedDocument and Swift 6
I open this post to bring attention to overlooked UIManagedDocument. It still marked with @MainActor despite the fact that UIDocument is gonna be nonisolated in iOS 26.1. Here is what we will have with iOS 26.1 (the fix was there since, at least, beta 2): UIDocument was incorrectly annotated to be main actor only. This has been corrected. As a result you might see new warnings or errors show up in your Swift code using UIDocument. (149990945) Seems that UIManagedDocument should also have to be corrected the same way. Otherwise, in Swift 6 we will have crashes. Feedback report for this issue is FB20555456.

Reply to How to change the system timezone
There isn’t an API to change the system time zone. If you’d like to see that change, I encourage you to file an enhancement request that outlines what you want to do and why. And if you do file an ER, please post your bug number, just for the record. Regarding the systemsetup tool, that tool is aimed at system admins. It’s not intended to be a substitute for an API. You can attempt to use it as such, but in my experience such attempts are usually less than satisfactory.

How to change the system timezone
Hello, I would like to change the system timezone in macOS, given a timezone identifier in the IANA timezone database. is 'systemsetup -settimezone' the only available tool or API that can be used to change the timezone? I have observed that TimeZone(identifier:) can initialize a TimeZone from any identifier in the tz database, but many identifiers are missing from the list accepted by systemsetup. For example, if the user has set the timezone to Mumbai - India in system settings, the timezone identifier returned by 'systemsetup -gettimezone' is Asia/Kolkata, which is not in the list printed by 'systemsetup -listtimezones'. What is the recommended way to map a IANA timezone name (or a TimeZone object) to one of the timezone names accepted by 'systemsetup'?

Reply to WiFi aware demo paring issue
It sounds like you’re building an accessory and you want to use Wi-Fi Aware to talk to that accessory from iOS. If so, go to Developer > Accessories, download Accessory Design Guidelines for Apple Devices, and review the Wi-Fi Aware chapter.

Reply to How to use the WebAssembly (wasm) binary module in macos App
Oh, you’re a system extension. That changes things. System extensions, due to their privileges position on the system, are not allow to use entitlements to disable the additional security measures imposed by the hardened runtime. The only exception that that rule is that macOS platform extensions [1] are allowed to use JIT via the com.apple.security.cs.allow-jit entitlement. Sadly this isn’t documented on the Hardened Runtime page, and I’ve filed a bug to get that fixed (r. 164078299). So, if you want to use JIT in your sysex, you can’t lean on the com.apple.security.cs.allow-unsigned-executable-memory compatibility crutch. You’ll have to do the right thing and use com.apple.security.cs.allow-jit, as explained in Porting just-in-time compilers to Apple silicon.

Reply to App Packaging: bundle format unrecognized, invalid, or unsuitable
I recommend that you seek help from your third-party vendor here. It seems likely that they’ll have a well-trodden path that you can follow for this. If you decide to debug this yourself, I have some general hints. To start, dont use --deep when signing code. For an explanation as to why not, see --deep Considered Harmful. Rather, sign each code item separately, from the inside out. Creating distribution-signed code for macOS explains that process in detail. I think that’ll reveal that there’s an issue with FMWrapper.framework. If so, that’s good, because gives you something to focus on. One of the most common causes of weird problems signing frameworks is that folks copy the framework without preserving symlinks. You should check that’s not the case here.

Creating an URL bookmark in macOS 26.1 of a Windows NTFS fileshare returns a bookmark with access to the local drive
Since macOS 26.1, creating bookmark data based on a NSOpenPanel URL, does not return the expected bookmark data when the selected source concerns a Windows NTFS fileshare. When the returned data is being resolved, the returned URL points to the local drive of the current Mac. Which is of course super confusing for the user. This issue did not occur in macOS 26.0 and older. In essence, the following code line with 'url' based on an URL from a NSOpenPanel after selecting the root of a Windows NTFS share, creates an incorrect bookmark in macOS 26.1: let bookmark = try url.bookmarkData(options: .withSecurityScope, includingResourceValuesForKeys: nil, relativeTo: nil) I have tested this on two different Macs with macOS 26.1 with two different Windows PC both hosting NTFS files shares via SMB. My questions: Have anyone else encountered this issue in macOS 26? Perhaps even with other fileshare types? Is there a workaround or some new project configuration needed in Xcode to get this working?

PDF links in WKWebView not clickable on iOS 26 (working on pre-iOS 26)
Hello Apple Developer Community, I'm experiencing an issue with PDF link interaction in WKWebView that appears to be specific to iOS 26. Problem Description: I'm loading a PDF in WKWebView.The links may vary widely and are not necessarily DPF, so I need to load them using WKWebView. On iOS versions prior to 26, links within the PDF are clickable and work correctly. On iOS 26, the same links are not clickable (no response when tapped). Expected Behavior: PDF links should remain clickable and functional across all iOS versions. What I've Tried: Tested opening the PDF directly in Safari on iOS 26 - links still not clickable This suggests the issue might be related to changes in the system's PDF rendering engine Reproduction Steps: Load the PDF URL in WKWebView Navigate to page 12 Attempt to tap the link Environment: Test Devices: iPhone 15(26.0 ) / iPhone 16 Pro Max(18.0.1 ) Xcode: 16.2 Questions: Is this an intentional change in iOS
