Xcode 16.2 runs well, but encountered the problem in Xcode 16.3.

Hello, we are struggling for hours with the following issue: I have an individual developer account and since yesterday I'm member of developer team with an own organization account. I have access to an app in the team account as an "App-Manager", also the option "Access to Certificates, Identifiers & Profiles" is activated and I can see that it is activated for my account in AppstoreConnect. In "Apple Developer" I can also see the team and can switch to. But then I do not see the "Certificates, Identifiers & Profiles" menu entry. Also the team is not showing up in XCode. What am I missing? Thanks and regards Philipp

When I try to run a simple executable from Cmake, I get this error. dyld[5005]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[5005]: Library not loaded: /usr/lib/libSystem.B.dylib Referenced from: <7EB1C677-BB05-338C-8B29-CC2803CB8C21> /Users/pop/Desktop/Lang Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache), '/usr/local/lib/libSystem.B.dylib' (no such file) I have tried looking for my file sudo find / -name libSystem.B.dylib but not luck. I am using an M1 chip and Ventura 13.1. Please ask for more details if you need them, as I really have no idea what to do about my problem.

Hello everyone! When I run UI Tests on Xcode Cloud, I often encounter unexpected failures. Checking the screen recording, I found that the iOS Simulator could go into a black screen with a white Apple logo and a progress bar for a period after the test starts. This behavior of the Simulator causes my app's UI Tests to fail randomly, which greatly affects the practical use of UI Tests. I suspect this phenomenon is unrelated to my app and test cases, so I'm asking if anyone else has encountered a similar issue. 🤔

I recently switched to Mac OS 12 and XCode 13. I did some work on my application and rebuilt it. Now there is no Help Book. I didn't change the property lists and everything looks right. When I open the Help Book the application either opens a window with a message that the content is currently unavailable or it opens a Help Book window with no content. When this second thing happens the log window shows "entering AHRegistered help Book" but it doesn't appear. Does anyone have any suggestions?

My MBP M1 Pro gets really hot. iOS 26.1 Simulator in Xcode 26.1 makes ReportCrash process run at 60-160% of CPU shows Activity Monitor. MacOS 26.1. I've reported this via Feedback Assistant: FB20918609. Is there a way to quit this process permanently? When I Force Quit this it opens again immediately. Only way to stop it is to quit Simulator. But then again, I need to use the Simulator.

I am unable to download the iOS 26.1 Simulator Runtime through Xcode 26.1 on macOS 26.1 (Build 25B78). Issue Details: When attempting to download via Xcode Settings → Platforms, the download fails with error code 41 (DVTDownloadableErrorDomain) and error code 60 (MADownloadCannotConnectToHost) The error message states: "Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({RequestedBuild = 23B80;})" I receive HTTP 403 Forbidden when accessing mesu.apple.com/assets/ Steps Attempted: Downloaded via Xcode Settings → Component → iOS 26.1 Simulator Tried command line: xcodebuild -downloadPlatform iOS Searched https://developer.apple.com/download/all/ - iOS 26.1 Simulator Runtime not listed Tested with different networks (home WiFi, VPN, mobile hotspot) Disabled proxy settings Flushed DNS cache All attempts result in the same error. Important Notes: Xcode 26.1 shows iOS Simulator SDK 26.1 (Build 23B77) is available However, Xcode attempts to download Build 23B80, which appears unavailable I experienced a similar issue previously with Xcode 16.4 requesting iOS 18.4 Simulator Runtime, which was also unavailable for download Impact: Without the iOS 26.1 Simulator Runtime, I cannot develop or test iOS applications. macOS 26.1 requires Xcode 26.1, which in turn requires iOS 26.1 runtime, leaving me unable to perform any iOS development work. Questions: Is iOS 26.1 Simulator Runtime (Build 23B80) officially released? Is there a direct download link available? Should Xcode 26.1 be requesting Build 23B77 instead of 23B80? Is there any account restriction preventing me from downloading newer simulator runtimes? System Information: macOS: 26.1 (Build 25B78) Xcode: 26.1 (Build 17B55) Error description: Download failed.

I just submitted a feedback for this (FB9662125) but in the spirit of “share and enjoy”… The cool new Generate Info.plist File feature in Xcode 13 crashes if you try to put an NSLocationTemporaryUsageDescriptionDictionary in your Info.plist file. Here’s a simple repro scenario: Create a minimal iOS app (no Core Data, no tests) Go to target settings → Info tab → Custom iOS Target Properties Click the (+) button on any row to begin inserting a new row Select Privacy - Location Temporary Usage Description Dictionary Click somewhere else or press Return to commit the selection Xcode crashes immediately More generally, it seems that Xcode crashes any time it tries to regenerate your Info.plist file if it contains an NSLocationTemporaryUsageDescriptionDictionary, even if (for example) you manually pasted that dictionary into the file earlier. In that case, merely tapping the (+) button in step 3 above is enough to crash it.

I have an iPhone 14 running iOS 16.1 and my series 5 watch running watchOS 9.1. I was able to turn on Developer Mode on the phone by going to Settings--> Privacy & Security --> Developer Mode. On the watch however (I'm doing this directly on the watch and not on the watch app on the phone) once I'm in Privacy & Security, there is no option to select Developer Mode. How do I get my watch in Developer Mode in order to get a successful build in xCode?

I have had this notice for a while: Registration is being processed for these devices. They may become available for development and ad hoc distribution in 24 to 72 hours. Changes to device availability will appear in the Status column. The status for my new iPhone has been stuck in this "Processing" state. See image:

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)

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

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?

Out of nowhere I got some red banner on top of my iPhone 13 mini / iOS 17.5. I cannot pin point the root cause of this. What I can say is that it only happens to Simulators of a certain type, e.g. iPhone 12 and 13 mini, but not iPhone 14 for example. I have installed Xcode 26.1.0 and 26.1.1, out of which 26.1.0 is selected: $ xcode-select -p /Applications/Xcode-26.1.0.app/Contents/Developer And following runtimes: $ xcrun simctl runtime list == Disk Images == -- iOS -- iOS 17.5 (21F79) - CF933623-A258-44F8-B248-C0F25C0C343B (Ready) iOS 26.1 (23B80) - D11C3CDC-EE3D-44CC-8B92-9B7D00B54B0B (Ready) Total Disk Images: 2 (14.6G) Installing the newer 26.1 23B86 runtime doesn't help either.

It is gone from where I used to find it on Apple’s web site. Is it deprecated or no longer available?

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

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.

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
