Reply to Xcode Version 26.0.1 (17A400) Model assets are unavailable
I do not think it is related to China as I live in Europe and get the same problem on my work MacBook Pro. The weird thing is that I get mixed results from a playground in Xcode (see attached pictures). Both ready to go and Model assets are unavailable. My managed macBook Pro has a profile that blocks only two things from Apple Intelligence: Allow integration with external intelligence services (macOS 15.2 or later) Allow Apple Intelligence: external intelligence workspace IDs (macOS 15.3 or later) I'm on Tahoe 26.0.1 and Apple M2 Pro. Any suggestion to allow me to run Foundation Models on my Mac? (At home, on my private MacBook Pro, everything works as expected)

Reply to Potential Structural Swift Concurrency Issue: unsafeForcedSync called from Swift Concurrent context
interferon, It’s better to reply as a reply, rather than in the comments; see Quinn’s Top Ten DevForums Tips for this and other titbits. You wrote: How much should I worry about this error? That depends on what the backtrace looks like. If the backtrace leads to your code, that’s something you should worry about. If the backtrace only shows system code, that makes this log noise, as defined here. [quote='860615022, pi80223, /thread/802423?answerId=860615022#860615022, /profile/pi80223'] I've seen this error message too when running a very simple SwiftUI app [/quote] I tried that here in my office and didn’t see the log. Specifically: Using Xcode 26.0.1 on macOS 15.6.1, I created a new project from the macOS > App target, choosing SwiftUI as the language. I ran that on my iOS 26.0 (23A341) test device (by a strange coincidence, it’s also an iPhone 16). I waited for 10 seconds. Then swiped up from bottom to send it to the background. And it’s a bummer I can’t reproduce it because I might be

Reply to What is the memory limit for a network extension?
[quote='856112022, Evozi, /thread/73148?answerId=856112022#856112022, /profile/Evozi'] How about iOS 26? [/quote] AFAICT the limits are unchanged on iOS 26. If you’d like to see bigger limits, the best way to get that feedback in front of the folks who have the power to enact change is file it in Feedback Assistant. Make sure include details about what you’re trying to do and why the current limits are negatively affecting your users. Please post your bug number, just for the record. Also, keep in mind that iOS 26 runs on old devices which are significantly more memory constrained than the shiny new hardware you might be using. My daughter may one day have to give up her iPhone SE (2nd generation), and thus accepted the new reality of Face ID, but today is not that day (-: Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to SSL certificate failure
[quote='860505022, jameseasylog, /thread/799838?answerId=860505022#860505022, /profile/jameseasylog'] I would guess this is because iOS 16 and earlier doesn't have Sectigo root certificates loaded [/quote] It’d be better to check rather than guess. Which brings me back to this comment: [quote='857543022, DTS Engineer, /thread/799838?answerId=857543022#857543022'] There’s a bunch of links … in Networking Resources. [/quote] Networking Resources include various links to the Apple Support articles that explain which root certificates are installed on which versions of iOS. I’m not able to speak for Sectigo, obviously, but a quick ’net search for Sectigo Public Server Authentication Root R46 suggests that they are in the process of transitioning from one root to another. If iOS 16 compatibility is important to you, I recommend that you discuss this with them. It’s possible that they might have some advice for how to tweak your server to be compatible.

AsyncRenderer causes crashes in ForEach when in Swift 6 language mode
Hi! We've recently done a big migration to Swift 6 language mode in our app and are now getting reports of crashes occurring due to closures in our SwiftUI code (most often the view builder in ForEach) not running on the main queue but instead running on the queue com.apple.SwiftUI.AsyncRenderer. One example of a call stack (ScheduleListView is our view that is in Swift 6 mode): Thread 16 #0 (null) in _dispatch_assert_queue_fail () #1 (null) in dispatch_assert_queue$V2.cold.1 () #2 (null) in dispatch_assert_queue () #3 (null) in swift_task_isCurrentExecutorWithFlagsImpl(swift::SerialExecutorRef, swift::swift_task_is_current_executor_flag) () #4 (null) in closure #2 in closure #1 in closure #1 in ScheduleListView.body.getter () #5 (null) in closure #1 in ForEachState.item(at:offset:) () #6 (null) in partial apply for closure #1 in ForEachState.item(at:offset:) () #8 (null) in partial apply for closure #1 in _withObservation(do:) () ....

MDM Profile Installation Issue on iPhone 17 - Suspected Parameter Transmission Error
Issue Description: We are experiencing MDM profile installation failures specifically on iPhone 17 devices. After extensive testing and comparison between affected and working devices, we suspect this appears to be a parameter transmission error rather than device settings. Technical Analysis: Device Settings Comparison: No differences found between problematic and working devices in system settings, indicating this is not a configuration issue. Suspected Parameter Transmission Error: • Device model information appears to be restricted or blocked during profile download • User ID and phone number parameters are not being transmitted to the server • Installation logs show missing login ID and phone number entries Symptoms: • During MDM profile installation, the Apps & Restrictions section that should appear is missing • Profile download parameters are suspected to not be properly transmitted to the server • Installation process fails at the profile configuration stage Critical Fi

Reply to iPadOS 26 - TableView auto scrolling bug
Although the code may not be using the best or latest practices, that is not the main concern. It seems that most methods that modify the layout of the tableView, either directly or indirectly, results in the strange auto scrolling behavior. Or maybe the issue is triggered when the tableView does not fill the entire view. The mechanics of the bug are not fully known. The conditions behind this do not seem to make sense. navigationControllerWithVC.navigationBar.isTranslucent = false for example, may not be using best practices, but why does that cause the table to start auto scrolling when being reloaded? The same can be asked for the safeArea top anchor scenario in the original code. Disregarding all of the navigation bar stuff, consider another case where we may want to present a label or some other content above the tableView. If the setupTableView() function is replaced with the code below, this will also trigger the auto scrolling issue: func setupTableViewWithLabelAbove() { tableView.delegate = self tabl

[Regression] Core Location underground positioning inaccurate on iOS 26.1 beta (23B5044i)
Summary While parallel testing Core Location on the new iOS 26.1 beta (23B5044i), I observed what I believe to be a regression of the issue described here: https://developer.apple.com/forums/thread/779192 Specifically, user positioning underground subway stations is noticeably inaccurate on the beta, whereas the same scenarios remain accurate on the unupgraded device below. I work with the MTA (New York City) and work with the OP of that thread. Happy to provide additional testing or details if helpful. Please let me know what else you need. Test Info Riding NYCT from Wall St to 34th St Penn Station on the 2 train carrying two iphones Recording: https://limewire.com/d/dpTWi#pDC3GRYIdE Expected: Consistent underground positioning comparable to prior releases. Actual: Degraded/inaccurate underground positioning on iOS 26.1 beta. Test Devices Left Screen: iPhone 15 Pro Max - iOS 26.1 beta (23B5044i) Right Screen: iPhone 11 - iOS 18.6.2 (22G100) Blue dots show location set by C

Multiple-frames BlendShape (failed) Animation in Reality Composer Pro
Goal: To render in an apple vision pro app, the solid-mechanics 3D simulation results coming form an FEA code. Starting point: I have surface vtks with deformations on each node. Each time step has a a mesh with the nodal coordinates. This is straighforward translatable to a usd MeshSequence. Unfortunately, the results cannot be simplified to a scaling o linear transformation as you would do with other game-oriented animations. Tools: Right now, I am using Xcode and reality composer pro (RCP) to build the scenes. Technical limitations: I am aware that RCP can do animations with BlendMesh and skeletons and that MeshSequence is not a problem. Progress: Coverting to the sequence of vtk meshes to a usd MeshSequence is straighforward. This animates correctly in Preview and Blender (see screenshot). I managed to convert from MeshSequence to multiple keys and BlendMesh. This also animates correctly in Blender and preview. Unfortunately, the BlendMesh of multiple blended meshes shows a zero animatio

Xcode 26 gets stuck frequently
Hi, Ever since I updated to macOS Tahoe and started using Xcode 26 daily, I've run into an issue where it gets stuck very frequently when launching and running my app in the simulator. It happens with the main app target as well as when running unit tests. If I restart Xcode and the simulator app, it works fine again for a while, but after some use, it goes back to the same situation. In Activity Monitor, Xcode ends up at 1000% CPU utilization for a minute or more, basically rendering the simulator and the debugger stuck. If I untick the Debug Executable option in the scheme editor, it works fine as well. Anyone else run into the same situation, or are there any tips I can follow to fix this issue? It makes it really tedious to make changes and then be stalled for a minute or more to see the app run. I've restarted the Mac, erased the booted simulator as well. I'm on a MacBook Pro M4 Pro. Everything used to run fine before macOS Tahoe / Xcode 26 on my main device. In fact, I used to run macO

xcodebuild -exportLocalizations Fails Due to Cross-Platform Dependencies
I'm working on a large multi-platform iOS project (iOS, iPadOS, watchOS, tvOS, visionOS) and have successfully migrated from legacy .strings files to modern String Catalogs (.xcstrings).

Error executing program on simulator
Hi Team, I am getting following error when executing a program on the simulator. Warning: CocoaPods is installed but broken. Skipping pod install. You appear to have CocoaPods installed but it is not working. This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it. This can usually be fixed by re-installing CocoaPods. For re-installation instructions, see https://guides.cocoapods.org/using/getting-started.html#installation CocoaPods not installed or not in valid state. Error launching application on iPhone 17. I tried to install cocoapods using below command which gave me another error. gem install cocoapods This gave me below error.

Reply to Potential Structural Swift Concurrency Issue: unsafeForcedSync called from Swift Concurrent context
I've seen this error message too when running a very simple SwiftUI app (built using Xcode 26.0 (17A324)) on my device (iPhone 16 running iOS 26.0 (23A341)): Start the app Wait 10 seconds Send the app to the background. No other user interaction is necessary. The LLDB statement you provided does catch the location of the error message. But the stack trace is not helpful, as non of my code is involved. But what I've seen is that the error message is written to the console when the app is sent for the first time to the background. It doesn't appear anymore afterwards. The call stack I've captured is: #0 0x00000001a74e1280 in os_log () #1 0x00000001914d4218 in ___lldb_unnamed_symbol7481 () #2 0x000000018b2855c0 in ___lldb_unnamed_symbol14749 () #3 0x00000001914dc944 in ___lldb_unnamed_symbol7669 () #4 0x00000001914dce24 in ___lldb_unnamed_symbol7677 () #5 0x00000001de688520 in partial apply forwarder for closure #1 (Swift.UnsafeMutablePointer>) -> τ_0_0 in Observation.generateAccessList&l
