Altool cannot authenticate with a managed Apple account
I am trying to list the providers on a managed Apple account using altool but I am getting an error. I am using the following command: xcrun altool --list-providers -u <apple-id> -p <app-specific-password> The error message indicates that a general error has occurred but does not specify what the root cause may be. 2026-01-05 11:13:29.272 ERROR: [altool.600001E6C1C0] Auth context delegate failed to get headers. Error Domain=ITunesConnectFoundationErrorDomain Code=1611 "Unable to generate an Apple Connect token at this time due to a general error" UserInfo={NSLocalizedDescription=Unable to generate an Apple Connect token at this time due to a general error} Failed to get providers. 2026-01-05 11:13:29.273 ERROR: [altool.600001E6C1C0] Unable to generate an Apple Connect token at this time due to a general error (1611) This command worked before the Apple ID was converted to a managed account. I have tried other managed accounts, as well as creating new app specific passwords but all fail with the same error. How can I accomplish this task with a managed Apple account?

Xcode 26 can no longer launch, and crashes immediately
Each time I try to launch Xcode 26, it immediately crashes in SourceEditorDataSource.ideChat_gracefullyApplyChangesToReflect. I'm now no longer able to use Xcode. A partial crash log attached. So far I've tried deleting derived data, rebooting, deleting ~/Library/Caches/com.apple.dt.Xcode. What should I do? Thank you in advance for any help. crash-report.txt

App icon not displaying correctly in AppStore
I'm having a strange issue with my iOS app icon rendering in the App Store - it seems to be low-res and clipping part of the image. I updated the icon in Icon Composer to apply the liquid glass overlay for the new build. It looks fine on the device and the asset itself isn't corrupted. I think it might be a resolution issue since the small icon thumbnails in App Store Connect have the same problem, but they look fine when I click through to the larger preview. Has anyone else run into this and figured out a fix?

iOS Simulators Fail Download
I've been going through different fixes for a few weeks and nothing seems to work.

Difficult to use XCode with Apple Watch
Trying to develop a little Watch app in Swift, and it's been kind of a miserable experience. I constantly get transport errors trying to connect to my watch. I've tried the trick of putting the Mac and the watch on my iPhone hotspot instead of just on the same WiFi network, but I am not sure that actually helps. I can run maybe once or twice, and then the transport error happens and it's very hard to get XCode to recognize the watch again. Also, when it DOES connect, it seems that XCode almost always loses the debugging connection (I just continue, and it IS actually running on the Watch at that point, but no debugger).

Can DEVELOPER_DIR or xcode-select support Command Line Tools at custom paths?
I'm trying to manage multiple Command Line Tools versions side-by-side (e.g., 16.2 and 26.2). I renamed the CLT directory to /Library/Developer/CommandLineTools-26.2.0 and set: xcode-select -s /Library/Developer/CommandLineTools-26.2.0 or DEVELOPER_DIR=/Library/Developer/CommandLineTools-26.2.0 Both result in: c++: error: unable to find Xcode installation from active developer path "/Library/Developer/CommandLineTools-26.2.0" It appears CLT only works at the fixed path /Library/Developer/CommandLineTools, unlike Xcode which can be at any location. Is this by design? Is there a supported way to use multiple CLT versions in parallel, similar to how multiple Xcode versions can coexist?

Xcode 26.1 Simulator download fails with DVTDownloadableErrorDomain code 41 and code 49 on macOS 26.1
I'm trying to download an iOS Simulator runtime in Xcode 26.2 or 26.1 on macOS 26.1, but the download keeps failing with the following error: Download failed. Domain: DVTDownloadableErrorDomain Code: 41 Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({ RequestedBuild = 23C54;}) Domain: DVTDownloadsUtilitiesErrorDomain. Code: -1. 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;} macOS &amp; Xcode Info: macOS Version: 26.1 (Build 25B78) Xcode Version: 26.2 (24553) (Build 17C52) What I've tried so far: Formatted my Mac and reinstalled Xcode multiple times. Completely deleted Xcode and its related files several times (/Applications/Xcode.app, caches, preferences). Tried different internet connections from multiple locations. Checked Apple servers and verified network. Attempted downloading other simulator runtimes (fail). but download fails immediately with DVTDownloadableErrorDomain Code 41 and bad URL error. Question: How can I fix the simulator download issue in Xcode 26.2 on macOS 26.1? Is there a known workaround for the bad URL / catalog download error?

xCode 26.2 Debug exetubale ON crashes on ios 26.2 devices
Hi, I am running build on ios 26.2 device, connected with cable (not wifi) and it crashes because files are not loaded or something. But when i turn off Debug Exetuble, it works just fine. Also, tried to run on ios 18.2 device, with Debug executable On - everything is ok, and breakpoints work. My guess, App crashes on reading and loading Assets and others app files like certificates. XCode run logs shows: **"Too many file errors". ** sample.txt xcode_run_logs.txt Also, exectued image list on lldb console, could not attach here, if needed i can add it with some url here.

Nasty problems in Xcode 26.2: Apple Intelligence crash & Source Code Control Failure
I know this post isn't going to give a lot of details, but what I experienced tonight was so completely weird that I wanted to get it posted here in case others run into it: FIRST: All was well until I made a trivial change to a large Objective-C++ module. I suddenly got the idea to look at that line in the code review pane, to see if that area of code had ever had recent modifications. But, the entire module showed up as modified -- one giant change bar, with nothing on the right side of the code review pane, no matter what commit I selected. Then I noticed that the two lines of code which had all of 4 characters edited were no longer showing any change bars. Yet, the file showed up as "modified". Still, the exact line changes were not showing in the source code navigator, even though other files showed their changes. Note I'm connected to our remote repo on github. I did some command line git checks of the local repo, and the changes were there (as yet unstaged). So -- I figured, I'm gonna ask the Apple Coding Assistant what's up. And it gave some fantastic advice, especially on how to confirm the changes really were in the repo ready to stage and commit and push. Which I did. But despite following a couple hours of wonderful suggestions, I could never get the change bars back -- for this one specific file! (yes, the file was in the repo, and in the project -- everything seemed OK with the file itself -- nothing had changed in the project, which compiled and ran perfectly with my changes). SECOND -- suddenly, the AI assistant seemed to crash Xcode. When I went to re-run Xcode, it just crashed exactly the same. The crash log indicated "Xcode is crashing inside the IDEIntelligenceChat plugin while it’s trying to “apply changes” to a Source Editor buffer". Ultimately, I needed to restart Xcode holding down the SHIFT key. I could open other projects, but not the one I had been working on. So I turned OFF apple Intelligence (thanks, ChatGPT). That allowed me to launch. It sounds like some sort of corrupt Apple Intelligence chat logs and/or caches, which ChatGPT has given me extensive suggestions for deleting. I don't have the energy to attack that tonight -- I did an additional Time Machine backup and hope to take a closer look tomorrow. Ideally -- I'd rather NOT lose all my on-going coding assistant chats for this project -- I had some ongoing suggestions I was working on. But more concerning is the weirdness with changebars affecting this one 7,000 line .mm file. It doesn't seem like there's anything that should affect those change bars for ONE FILE that is in the repo and where changes can be seen from a git diff command line operation. If it's a bug -- I can live with it. But it's worrisome. Other than that, Xcode 26.2 has been running great! Unlike 26.1, which insisted on re-compiling all 600 files in my project every time I ran/debugged, 26.2 just does the 2-6 modified files -- a perfect incremental compile. I've saved HOURS of wasted unnecessary compilation since 26.2 was released.

Debugger breakpoints not hitting since updating to macOS 26.1
Hi, I have started facing an issue with Xcode since updating to macOS 26.1. The debugger is not stopping at breakpoints in Objective-C code, however breakpoints in Swift file are working fine. I am using Xcode 16.4. For breakpoints in Objective-C files I have started to get this message since the OS update - 'Xcode won't pause at this breakpoint because it has not been resolved.' I have already tried cleaning derived data and build folder. I do not want to upgrade to Xcode 26. Could someone help with the fix? Thanks

Building with Xcode on macOS Tahoe does not launch in iOS 12
When trying to launch an app built with Xcode in iOS12, differences occur depending on the macOS version on which Xcode is installed. When building with Xcode 26.2 (or Xcode 16.4) installed on macOS Sequoia, installing it on iOS 12 and tapping the app icon launches the app. When building with Xcode 26.2 (or Xcode 16.4) installed on macOS Tahoe, installing it on iOS 12 and tapping the app icon does not launch the app. The following log was displayed upon launch: Dec 15 11:46:35 xxx assertiond[58] <Notice>: Submitting new job for "com.xxx.sample" on behalf of <BKProcess: 0x10151a710; SpringBoard; com.apple.springboard; pid: 48; agency: SystemShell; visibility: foreground; task: running> Dec 15 11:46:35 xxx assertiond[58] <Notice>: Submitted job with label: UIKitApplication:com.xxx.sample[0x2dfd][58] Dec 15 11:46:35 xxx assertiond[58] <Notice>: Unable to get pid for 'UIKitApplication:com.xxx.sample[0x2dfd][58]': No such process (3) The same issue occurs with both .app and .ipa. I would like to know the technical reason behind this, if anyone knows, please let me know.

Xcode Intelligence AI feature seems to fail on slow networks
Intelligence AI powered feature fails on complex project with network error when “Reasoning” is set higher then “Low”. The visual feedback shows sending some context and answer being generated, but eventually stops with network error. Retries with “Reasoning” set higher than “Low”. won’t help, but retries or same queries with “Low” or "Minimal" reasoning always succeed. It is obvious that connectivity is not lost but looks like some kind of timeout expires and cancels the response, even not the request. Visual feedback shows the context being successfully uploaded and even shows the indicator of the answer being generated.

No output appears on tvOS simulator when creating a new game project Xcode 26.2
When I create a new tvOS game and run the default project the simulator window appears but nothing is shown. When I create a MultiPlatform Game project and run the demo project for AppleTV the simulator work correctly. I do not get any errors just a blank screen. Also clicking on the Home icon in the simulator or the actual AppleTV does nothing. Drew

Xcode Playgrounds crashes upon microphone access
Sorry if this is a dumb question. I’m still a beginner. I created an Xcode Playground app with Microphone and Speech Recognition capabilities enabled, along with a backup Info.plist. However, when running the app on Mac Catalyst, a real device, or the iOS and iPadOS simulators, it crashes right after the Speech Recognition permission popup and again after the Microphone permission popup. For extra context, the app initially worked fine in the Swift Playgrounds app, but that environment uses an outdated SDK, so it no longer supports some of the features I’ve implemented. I’m also struggling to find clear, beginner-friendly documentation that explains how AVAudioEngine works, which is making it hard to understand what’s going wrong and how to debug it.

Swift Playground Assets missing??
I’m seeing what looks like a change or possible bug in Xcode when creating a new Swift Playground. When I create a Swift Playground using Xcode (File → New → Playground), the project is generated without an Assets folder. I’ve reproduced this multiple times with fresh Playgrounds to rule out user error and the folder is consistently missing. Previously, new Playgrounds included an Assets catalog by default, which makes this behavior surprising.

Finding method definition
Hi, I have a recurrent problem with an Xcode workspace that I cannot figure out how to solve: When I command-click a symbol (or press ctrl-cmd-J) to find its definition, and when that definition is in a header file belonging to a custom static library, Xcode opens a header located in the derivedData folder rather than in the project's source codes. The exact location of this file is not in the main 'Build' folder but rather in a folder that seems dedicated to indexing: derivedData/myProject/Index.noIndex/Build/Products/Debug/Include/theHeader.h Consequently the file opened by Xcode is uneditable, I have to close it and reopen the source using another method. Even when the correct header is already opened, and I try again, Xcode reopens the wrong file so that it's opened twice with different paths. In the config file of the main application project, I reference the sources of these static libraries like this: HEADER_SEARCH_PATHS = ${SRCROOT}/myLibrary1/Sources ${SRCROOT}/myLibrary2/Sources ${SRCROOT}/myLibrary3/Sources However, removing this doesn't fix the issue and I don't see any other related-settings. Any idea to fix this annoying issue would be greatly appreciated, thanks!
