Hello, I have multiple iOS applications using Xcode projects built with Flutter. Originally I created this applications with my Apple ID, however, since then I lost access to my Apple ID's email. I updated my Apple ID email to a new email and now I cannot even build an app locally for the iOS Simulator. I'm on macOS 15 / iOS 18 simulator. Here is the output from xcodebuild: DVTDeveloperAccountManager: Failed to load credentials for [OLD_EMAIL]: Error Domain=DVTDeveloperAccountCredentialsError Code=0 "Invalid credentials in keychain for [OLD_EMAIL], missing Xcode-Token" UserInfo={NSLocalizedDescription=Invalid credentials in keychain for [OLD_EMAIL], missing Xcode-Token} Where OLD_EMAIL is the old Apple ID email. When I go into my Keychain Access app, I remove all references to my old email, but they regenerate when trying to build the app. I've tried doing manually signing on the xcode project config, but that gives the same error as well. This is only on old projects. When I run a new project, I do not have any errors building or uploading to App Store Connect. Any help would be greatly appreciated. Thank you

I am using the latest version of Xcode 16, and I have created a GPX file in my project. However, I am unable to see or select the file to simulate the GPS location. I have attempted to uninstall and reinstall Xcode completely, but the issue persists. Has anyone encountered a similar problem? How can I resolve this? Thank you.

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?

We have a Xcode project consisting of: A mix of Swift and Objective-C code app code ~ 1600 source files. Roughly around 35 {XC}Frameworks. Some of them are binary and some of them are getting built as a dependency to our app, etc. Binary libraries. Most of the frameworks built together with app code are Objective-C or Swift-based, which have their own amount of sources files and framework dependencies. The binary frameworks mostly contain cross-platform C++ code. Our (the poor developers) frustration is that almost all time when we do a insignificant change (or even just tap Cmd-R without any changes) in Swift-file or Objective-C file (.m) and then build again then big sh*t show starts again... For example: Frameworks may get rebuilt even though they are not touched. Tons of app-level files get built again even though no interface changes, etc. was made. Module verifier keeps verifying modules not touched at all, which takes really long time. Xcode 16 didn't seems to improve the situation - on the contrary. Example of an untouched framework that for unknown reason goes trough this every time we build: I know it is hard to come with ideas to solve this for an unknown larger project. But do other people with similar-size projects also experience this or is re-building not an issue for you? Cheers!

Hi, I'm setting up Xcode and after updating MacOS to 15.2 and Xcode to 16.2, I cannot download the Predictive Code Completion Model. I've done some research and I haven't found any solution, specially since most people suggest that it randomly fixed itself, which for me hasn't been the case. I've tried restarting my Mac, uninstalling and reinstalling Xcode multiple times, I've also reinstalled MacOS from Recovery and haven't found any success (I'm also not running Xcode inside a VM, as I've seen this can cause some problems in this case). This is the error that I receive when I attempt to download the model: And here are the details: The operation couldn’t be completed. (IDELanguageModelKit.IDEModelDownloadAdapter.(unknown context at $11eba9a90).DownloadError error 3.)

XCode version: Version 16.0 (16A242d) macOS: 14.6.1 (23G93) Hi, I'm getting this error while uploading my app using XCode 16. I just updated XCode from 15 to 16. On XCode 15 it worked fine when I uploaded apps, no error no warnings, but on XCode 16 there are list of warnings for OneSignal framwork. Here is one of the error, and the others are all the same (OneSignal has multiple packages). Upload Symbols Failed The archive did not include a dSYM for the OneSignalUser.framework with the UUIDs [***]. Ensure that the archive's dSYM folder includes a DWARF file for OneSignalUser.framework with the expected UUIDs. My Podfile looks like this: target 'my_target' do # other packages pod 'OneSignal/OneSignal', '>= 5.0.0', '< 6.0' pod 'OneSignal/OneSignalInAppMessages', '>= 5.0.0', '< 6.0' end target 'OneSignalNotificationServiceExtension' do pod 'OneSignal/OneSignal', '>= 5.0.0', '< 6.0' pod 'OneSignal/OneSignalInAppMessages', '>= 5.0.0', '< 6.0' end OneSignal uses vendored frameworks, and I don't believe they provided the symbol files. Will this affect my app in any way? How can I resolve this issue?

I'm getting following message when launching #Playgrounds canvas with Xcode 26 beta 4. Here are things I've tried: Reinstall Xcode Reinstall components Removed derived data Run Disk Utility to fix permissions Tried to change Default Actor Isolation, Approachable Concurrency Changed around settings on Schemes: Run: Options and Diagnostics Created brand new project with default settings. Filed FB19003005 in Feedback Assistant. I'm surprised to see that I didn't see any posts on this during my search. So this could be isolated matter just to me.

Hi. Just update my MacBook Pro M1 with sequoia and Xcode and I got huge problem with preview on simply swiftui pages.

Hi Excited to try out the new Xcode Swift code completion ML tools demo'd yesterday at the SOTU. I am running macOS 14.5, using a VM Via Virtualization Framework ( UTM.app) to run macOS 15 Beta 1. Ive installed XCode 16 Beta 1 in my Host OS (macOS 14.5) and was able to successfully install, boot, and set up macOS 15 as a VM client. Ive installed Xcode 16 in my VM Client, and upon launch, was asked to download the Predictive Text model. I see this error: The operation couldn’t be completed.

Is there any way to stop previews from live updating? It's constantly running and that's nice when I'm developing, but I'd like it to pause updating when I'm not using the Xcode. It heats up my m1 air and drains unnecessary power reducing the battery levels significantly.

It would be nice for Apple to integrate chatgpt, Open AI, and create their own artificial intelligence. Siri is not equipped to answer questions that AI can. With increasing AI prevalence and usability, Apple is behind. Message to Apple: PLEASE UTILIZE AI TO MAKE APPLE THE BEST PLATFORM.

Since a few days, I'm trying to fetch our private SPM repo hosted on Azure via Xcode but without success. Actually they now accept only ssh key RSA-SHA2-256 or RSA-SHA2-512. So I created a new SSH key, but it seems the problem persists when I try to fetch spm repo or git clone via xcode: "You’re using ssh-rsa that is about to be deprecated and your request has been blocked intentionally. Any SSH session using SSH-RSA is subject to brown out (failure during random time periods). Please use rsa-sha2-256 or rsa-sha2-512 instead. For more details see aka.ms/ado-ssh-rsa-deprecation. remote: ERROR_SSH_UNSUPPORTED_CIPHER (7) (-20)" Even so I'm choosing the good new ssh key, it seems Xcode is sending wrong information about the new generated ssh key. Anyone is experiencing the same here?

Upgraded Xcode from 15.2 to 16.

SwiftUI preview hangs on "Preparing iPhone Simulator for Previews". Also simulator hangs when trying to build and run. This occurred after I installed iOS 17 simulator. I tried reverting back to an iOS 16 version of the simulator, but haven't figured out how to do that. Build and run to an iPhone device works fine. Any ideas would be appreciated. Thanks.

Attempting to launch a widget in Debug mode on Sonoma from Xcode 15 is failing with the following message: attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.) Looking in console I see this message: macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (MacGalleryWidget) (pid: 1851): (MacGalleryWidget) is hardened, (MacGalleryWidget) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger What Xcode settings should I be looking at to rectify this? I suspect I may have something that's out of whack.

I added a new liquid glass icon built with Icon Composer to my app. It works and looks great on iOS 26 but Xcode complains that required icon files for older versions are missing. I still have the old AppIcon in my Asset Catalog but it seems like it's not being used. How do I configure Xcode to use the old icons for iOS 18 and the new icon for iOS 26?

Hi, The launchscreen section in Xcode 16 RC keeps disappearing no matter what. Is anyone else seeing this issue? I submitted a bug report over a week ago about this problem. Dan Uff

This is really a disgusting function and I can't turn it off. Because the check box is grey, no way to turn it off. Even I connect my device via cables. Debug becomes slow. Although I connect my device via cable. And I'm developing a VPN application, it's rediculous that once I connect VPN from my device, Xcode will disconnect from my device. I can't stand this function any m ore. Does anyone know how to turn it off?

It's maddening. I just opened a file and now it's gone because I had the audacity to open another file. I've learned that I can double click the tab of the first file to make it a permanent tab... but, of course, I'll need to do that every time I ever open any file ever, and if I close that file and come back to it later I'm going to be constantly having to double click tabs just to make Xcode stop replacing my tabs for me. It's nuts. It's driving me insane. Please. Is there any way to just DISABLE the temporary tabs behavior? I don't find it helpful in any way and I find it to be destructive to my development workflows.
