Hi everyone, I’m experiencing a persistent issue when trying to download the iOS Simulator Runtime 26.1 on Xcode (version 26.1). The download always fails with the following error Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 I’m located in Brazil, so I initially thought it might be region-related, but I’ve already tried several attempts to fix it, including: Using VPNs for the US and Europe Installing the Xcode 26.2 beta Downgrading Xcode to earlier versions Reinstalling the same version of Xcode Restarting Xcode and my Mac Switching networks Clearing simulator support/device files Unfortunately, nothing has resolved the issue. Is anyone else facing this problem? Does anyone know a workaround or a manual way to download/install the iOS 26.1 simulator runtime? Thanks in advance!

Xcode Cloud builds are hanging forever at the final step, Prepare Build for App Store Connect. This is a common issue that requires some fix in Cupertino. Reporting this in the afternoon of Jan 13, Pacific Time.

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

Hi, Problem When playing videos on the Developer app on the Mac, there is no full screen button for the video. So it is not possible to play the video in full screen. Note I am not referring to the app going into full screen, the issue is with there is no option to play the video in full screen. Environment OS: macOS 26.2 (25C56) Developer app: Version 10.8.3 (1083.3.1) Feedback FB21343934 Recording Question Are others also facing this issue? Is there a workaround? Suggestion This seems to be recurring problem that seems get broken with app / OS releases. Please write some UI tests to ensure the full screen button is present. Would really appreciate if this gets fixed.

Hi there, We’re encountering this error in all of our builds when using the latest Xcode and macOS: The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again. In short, all builds are failing. I’ve tried fixing this by installing Metal and applying other solutions, but none of them worked reliably. Is there a way to ensure that the Metal Toolchain is installed on the CI machine?

Simply opening Simulator app (26.0) causes high CPU usage on macOS Tahoe (26.1). ReportCrash process usage is very high throughout and causes the system to heat up pretty soon. Looking into Console app for the logs found MercuryPosterExtension process is keep on crashing. (Check under Crash Reports) simctl Diagnose https://download.developer.apple.com/OS_X/OS_X_Logs/simctl_Diagnose_Logging_Instructions.pdf Share the Simulator Diagnose report while reporting, Thanks. I have raised a ticket/feedback with Apple. I request all of you to raise one too so this gets fixed soon. Apple Feedback Assistant - FB20985249

It seems like, by default, the preview pane tries to align to 50% of the editor pane's width. I prefer to shrink the preview pane to around ~30% of the screen so I have more space for code. This used to work fine—at least until I restarted Xcode. I never understood why the setting wouldn’t persist across sessions, but fine, that was a tradeoff I was willing to live with. However, with Xcode 16.3, it seems like Xcode forgets the manually adjusted preview pane width as soon as I switch to a different file. This has definitely impacted my productivity, as I now find myself readjusting the pane size dozens of times in a single session. Am I holding it wrong? Is anyone else experiencing this? And while we’re at it—why not make this a persistent setting so everyone can tweak the width to their liking?

Body: I am writing to report an ongoing issue with the Apple Developer Program enrollment process specifically affecting developers in India, along with significant concerns about Apple's support responsiveness in this region. Issue Summary: I have been attempting to enroll in the paid Apple Developer Program ($99/year) using the Apple Developer app on my iPhone for the past 4 days. Every enrollment attempt results in the following errors: "Unknown Error - Please try again" "Invalid Request - Service mapping to the requested URL is not available" My Setup (All Verified Correct): Apple ID Region: India Trusted Phone Number: +91 (India country code, matching my Apple ID region) Two-Factor Authentication: Enabled (genuine 2FA, not two-step verification) 2FA Devices: iPhone, MacBook Pro devices, and trusted phone number all verified Account Information: Legal name, address, date of birth, and email all updated and verified on account.apple.com Device: iPhone 17 Pro running latest iOS Troubleshooting Attempted: I have completed every troubleshooting step suggested by the community and by Apple Support myself: ✅ Verified genuine Two-Factor Authentication is enabled ✅ Confirmed Apple ID region matches trusted phone number region (+91) ✅ Updated all personal information (legal name, address, email) on account.apple.com ✅ Force restarted iPhone multiple times ✅ Uninstalled and reinstalled Apple Developer app ✅ Signed out and signed back in with correct Apple ID ✅ Tested on both WiFi and cellular data ✅ Waited 48+ hours between attempts None of these steps resolved the issue. Support Response Issues: This is where my frustration peaks. I have attempted to contact Apple Support multiple ways: Phone Support: Shows "Phone support is currently unavailable" (though it was available last week) Email Support: Submitted via developer.apple.com/support → No response for 4 days Previous Contact: Had contacted support last week, but the troubleshooting steps provided did not resolve the issue Current Status: No follow-up communication or resolution path from Apple Known Issue in India - Why This Matters: I have researched this extensively and found multiple threads in this forum (dating back months) with developers in India reporting identical errors during enrollment. To date, I have not found a single resolved thread with a working solution. This indicates: This is a documented, recurring issue affecting Indian developers specifically Apple appears to have backend infrastructure issues specific to India Support has not provided a resolution path despite multiple reports The Real Problem: Apple's Developer Program enrollment system appears to have specific bugs or limitations that prevent developers in India from successfully enrolling, yet: Support responsiveness is severely lacking There is no documented workaround or known resolution The support team seems unaware of or unprepared to handle this region-specific issue My Request: Acknowledgement from Apple that this is a known issue affecting India-based developers A concrete resolution path (whether manual backend enablement, account review, or system fix) Expected timeline for resolution: Improved support responsiveness - Developers deserve answers, not silence Additional Context: I am ready to provide screen recordings of the exact error I have all the necessary documentation (identity verification, address proof, etc.) I am willing to complete any additional verification steps I simply need clear communication and a path forward I have been developing for iOS and want to contribute to the Apple ecosystem. However, this enrollment barrier is preventing me from doing so. Apple's support infrastructure for India needs improvement, and this issue needs attention. If any Apple team member is monitoring this forum, please escalate this issue. Indian developers deserve better support and communication.

On iOS 18.0+ simulators, tap any share link button from any app, select "Save to Files", the "Save" button is disabled. In all previous simulator versions this works. This behavior even happens with default Apple apps like Photos. Simulator: Version 16.0 (1037) XCode: Version 16.1 beta (16B5001e) macOS: 14.6.1 (23G93)

Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Hi everyone, I recently updated to Xcode 26.0 and noticed that the “Extract Subview” refactoring option seems to be missing. Now, in Xcode 26, the only options I see under Editor -> Refactor -> are: Extract to Selection File Extract to Method Extract to Variable Extract All Occurrences But there’s no Extract Subview as there was before. Was Extract Subview intentionally removed in Xcode 26? Or is it hidden behind a new menu location or renamed?

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work. Is this a known bug? Is there a workaround to get it do auto-complete again?

When running a SwiftUI Multiplatform app in Xcode Cloud I'm getting the following error: CIWatcher encountered an error in CIWatcherTests failed with: Failed to install or launch the test runner. (Underlying Error: Could not launch “CIWatcherTests”. Runningboard has returned error 5. Please check the system logs for the underlying cause of the error. (Underlying Error: The operation couldn’t be completed. Launch failed. (Underlying Error: Launchd job spawn failed))) This runs fine on iOS and all those tests pass. The SwiftUI app on Mac is a menu bar app so I'm not sure if this could be the issue as it's not launching for some reason on the Xcode Cloud system? Maybe I need to add some run option to make this work? When run locally both iOS and macOS pass all the tests successfully

Hi there, I successfully created an AppIntent for our app, and when I had it in the same target as our main app it showed up fine in the shortcuts app. Then I realized that many of the new System Control widgets introduced in iOS 18 (e.g. lockscreen, control center) live in the widget extension target, but they also need to reference that same AppIntent. So to fix this, I thought I'd migrate out the code into it's own SPM package that both the WidgetExtension and the Main App processes can reference. However, after doing that and rebuilding, the intent no longer shows up in the Shortcuts app. Furthermore, my AppShortcutsProvider class now has this error when trying to define the list of appShortcuts: App Intent <name> should be in the same target as AppShortcutsProvider Is this intended, and if so, how do we reference the same AppIntent across multiple targets?

Hello, We are experiencing a persistent issue where macOS builds in Xcode Cloud consistently hang at the Archive stage. The build itself completes successfully, but no artifacts appear, and it seems the build gets stuck during artifact upload. These builds remain in this state for several days (currently 3 days and counting) not failing, but never finishing. We opened a support ticket (102756662562), but we have not received any response yet. We rely on Xcode Cloud for our entire CI/CD pipeline, and at the moment our workflow is completely blocked because of this issue. Has anyone encountered something similar or found a workaround? Thank you.

Upgraded to Tahoe 26.4 and Xcode 26.4 and realized Xcode is missing the documentation for Foundation. Occasionally, if other (not yet missing) documentation references a Foundation entity, such as a type, clicking on it may open in a web browser pointing to the externally hosted Apple documentation. Anyone else experiencing this or have a workaround (perhaps the documentation files are on disk but were somehow lost / disconnected from the Xcode doc browser)? I checked the release notes for 26.4 and for 26.3 but did not find a mention of anything like that. Filed an issue with Apple, please do too if you are affected so hopefully it will see some love and lead to restoring the documentation. Edited: found some possibly related files in my ~/Library and the newer version v302 (26.4 related, I think, is considerably smaller): du -sh ~/Library/Developer/Xcode/DocumentationCache/* | awk -F/ '{print $NF "\t" $1}' v296 1.0G v302 507M

I want to use a ci_script to change the CI_BUILD_NUMBER to a new value. But in XCODE CLOUD there seems to be no programmatic way to change it?

I'm facing an issue with Swift Playgrounds and files created in Xcode 16. It seems that Swift Playgrounds does not support Swift 6, but even when I create files specifically with Swift 5, Swift Playgrounds still reports that the files are unsupported. This creates a significant problem because macOS Sequoia does not allow me to revert to Xcode 15, which might have offered better compatibility. As it stands, I can't find a solution to work seamlessly between Xcode and Swift Playgrounds. Has anyone else encountered this issue? Are there any workarounds or updates planned to address this compatibility gap? Any advice would be greatly appreciated!

Hello everyone, I’m looking for some guidance to see if anyone has experienced a similar issue with the Apple Developer Program membership. About one week ago, I completed the payment for the membership. I received an email with the subject: We’re processing your order Wxxxxxxxxxx That email included the order details and cost, and shortly after that, I also received the CFDI invoice for the payment, so the charge appears to have been completed successfully. However, up to now: I have not received any membership confirmation email The membership does not appear under Subscriptions in my Apple ID It is not active in the Apple Developer app On the Apple Developer website, I still see the usual message as if the membership was not purchased: “Purchase your membership to continue your enrollment. Buy today” I understand Apple mentions that the purchase may take up to 48 hours to process, but it has now been more than a week with no changes. Has anyone else encountered this situation? Is it normal to receive the invoice but not have the membership activated? Would you recommend contacting Apple Developer Support at this point? Thanks in advance for any help or shared experiences.
