After updating my system to macOS Tahoe 26.1 and Xcode 26.1, all breakpoints in my project fail to work. When I run the application in Debug mode, any enabled breakpoint (blue) immediately becomes disabled (grayed out) the moment the app launches. The application runs, but the debugger never stops. This issue occurs in any location, including in the application's init() method, which should always be hit. This behavior suggests that the LLDB debugger is failing to attach to the process at launch or is being instructed not to enable breakpoints. System Configuration: Mac Model: MacBook Pro 14" (2021), Apple M1 Pro macOS Version: Tahoe 26.1 Xcode Version: 26.1 Project Type: SwiftUI App for macOS Troubleshooting Steps Performed (All Unsuccessful): We have performed an extensive series of troubleshooting steps to resolve the issue, none of which have worked. These steps include: Basic Project Cleaning: Cleaned the build folder (Product > Clean Build Folder). Deleted the entire DerivedData directory. Deleted the project's xcuserdata folder. Xcode & System Procedures: Restarted Xcode multiple times. Rebooted the Mac multiple times. Reinstalled Xcode Command Line Tools using xcode-select --install. Reset the Xcode path using sudo xcode-select --reset and sudo xcode-select -s /Applications/Xcode.app/Contents/Developer. Forced an update of the system's shared cache with xcrun simctl runtime dyld_shared_cache update --all. Project Build Settings Verification (for Debug configuration): Build Configuration: Verified that the "Run" scheme is set to Debug. Optimization Level: Confirmed it is set to No Optimization [-O0]. Debug Information Format: Confirmed it is set to DWARF with dSYM File. Strip Swift Symbols: Confirmed it is set to No. (This was a new setting noticed after the Xcode update). Enable Hardened Runtime: Attempted setting this to both Yes and No. The issue persists in both cases. Validate Workspace: Confirmed it is set to Yes. Code Signing: Verified that "Automatically manage signing" is enabled with a valid team. Manually deleted and re-created the "Apple Development" certificates via Xcode's Accounts settings. Direct LLDB Testing: Created a ~/.lldbinit file. Using breakpoint list, confirmed that LLDB starts with "No breakpoints currently set," indicating that Xcode is likely not passing the breakpoints to the debugger. Using settings set target.process.stop-on-entry true, confirmed that the app still does not stop on entry, suggesting the debugger is failing to attach to the process at all. Conclusion: Given that all standard and advanced troubleshooting steps have failed, and the issue started immediately after updating both macOS and Xcode to a non-public release (Tahoe 26.1 / Xcode 26.1), this appears to be a regression or a bug in the new development environment. The failure of stop-on-entry strongly suggests a fundamental issue with the debugger attachment process on this specific OS and Xcode combination.

Hi everyone, (you can answer in french) I’m french-rookie in xcode, and I have a problem: I’m trying to choice my custom font to add it in my Main.storyboard button, but it not works. I have my « Font provided by application » line in my Info.plist, with the name of my font in [0] (See images below) When I’m on storyboard button, I chose « custom » in font selector, then display font list but my custom font doesn’t appear. I already tried to install the font in my mac, but still stucked, nothing change 😭 Could you help me please? Thanks a lot (I specify that I scrupulously followed the way of doing explained on the Apple official page: Adding a Custom Font to Your App )

I am writing to report multiple issues encountered after updating to Xcode 26 Beta, which have significantly impacted my project's compilation and functionality. My project can run normally in Xcode16.3 version, Below are the specific problems, along with the steps I took to address them and the subsequent errors that arose: Symbol Not Found Error for _NSUserActivityTypeBrowsingWeb After updating to Xcode 26 Beta, my project failed to build with the error: "Symbol not found: _NSUserActivityTypeBrowsingWeb." To resolve this, I removed the MobileCoreServices framework from the Build Settings, as it appeared to be related. However, this led to a new error, indicating that this change introduced further complications. Clang++ Error: No Such File or Directory 'OpenGLES' Following the resolution of the first issue, I encountered a new error: "iOS clang++: error: no such file or directory: 'OpenGLES'." To address this, I added the OpenGLES.framework to the Build Phases. While this resolved the clang++ error, it triggered additional errors, suggesting that the underlying issue persists or new dependencies are conflicting. Recurring XIB File Compilation Errors My project uses XIB files, and every time I attempt to compile and run, Xcode reports errors related to different XIB files. Notably, when I open the reported XIB file, no errors are displayed within the Interface Builder. After saving or inspecting the file, the compilation error temporarily disappears, only for another XIB file to trigger the same issue in the next build. This creates a repetitive cycle. I have confirmed this is not a caching issue, as I clean the build cache (Product > Clean Build Folder) before each run. If I skip cleaning the cache, the OpenGLES-related error (Issue 2) reappears, indicating potential interactions between these problems. These issues have made development with Xcode 26 Beta extremely challenging, as each attempted fix seems to introduce new errors, and the XIB issue creates a persistent loop. My setup includes: Xcode Version: 26.0 beta 2 (17A5241o) macOS Version:15.4.1 (24E263)

Ever since I updated to Xcode 16.2, no device running iOS 18 shows up in Xcode. I can see the devices in Finder and Apple Configurator, but not in Xcode. When I run xcrun devicectl list devices, I also do not see the devices, so I assume the issue is in CoreDevice somewhere. I've tried many things I've seen suggested in similar threads (toggling developer mode, reinstalling Xcode, using a different physical cable, etc) and so far nothing has helped. This same behavior is also happening for my entire development team, which has been as difficult as you might imagine. Any info on how to resolve this would be much appreciated.

I'm trying to compile my iPad app with Xcode 16.2 and I'm consistently getting this error message: couldn't find compile unit for the macro table with offset = 0x0 This is happening at the GenerateDSymFile step. I've tried changing the debug format from Dwarf with Dsym to Dwarf and then back again, as I've read there was a problem with generating the dsyms. But the problem persists. I've tried searching for this error and found nothing online, so apparently I'm the only one! How strange. Are there any settings or flags I can change to try to get more information about what's going wrong?

ChatGPT in Xcode 26.1 is super slow for me, anyone else? The response returns quickly but the preview window takes a few seconds per line. What it used to do in a few seconds on 26.0 now takes tens of minutes. Anyone else running into this and have suggestions? I'm using the minimal setting on a fast internet connection.

Right now, I am trying the tutorial for SwiftUI from the Apple Developer Program inside of Xcode, but I encountered a problem. Inside of the selectable canvas mode in Xcode, I wanted to command-control-click the element (in this case, a text) to bring up the editing popover and select "Show SwiftUI Inspector." For some reason, on the popover menu, the only option was "Embed." I only wanted the menu point Show SwiftUI Inspector, and I also tried the shortcut Ctrl+Option, but nothing worked. Now is there another method to get to this menu? Or can you help me with that? Noah

To reproduce this bug create a new Xcode Project for IOS choose UIKit. In the app delegate add the following lines. As you can see in the above image . Line 19 with the initialization of PHPickerViewController has no compilation failure. Now lets add import WidgetKit As soon as widgetKit is imported a compiler error is thrown which is PHPickerViewController is not in scope. This worked with Xcode 16.4 It was possible to have a swift file with both WidgetKit implementations and PhotosUI implementations. This behavior has changed in Xcode 26/26.0.1 . Does anybody know why this happens , could not find any clues within the different versions of documentations. P.S Found a work around which raises further questions Adding import SwiftUI fixes this problem , I am genuinely curious on how this is happening on a compiler level.

Hi everyone, Since updating to Xcode 26, I’ve been running into an issue with the new ChatGPT integration inside Xcode. Even though I have an active ChatGPT Plus subscription (GPT-4 or GPT-5) and I’m signed in to my OpenAI account, Xcode doesn’t seem to recognize my paid plan. After reaching the free usage limit, I get the following message: “Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account or upgrade to ChatGPT Plus.” The issue is that I am already logged in with my ChatGPT Plus account, and everything works fine on the ChatGPT web app — but inside Xcode, it keeps treating me as a free user. Here’s what I’ve tried so far: • Signing out and back into ChatGPT from within Xcode • Restarting Xcode and macOS • Verifying that I’m logged in to ChatGPT in Safari • Updating both macOS and Xcode to the latest versions None of these steps have resolved the issue. It seems like Xcode isn’t syncing properly with OpenAI authentication, and therefore it applies the free-tier limits even for paid accounts. Has anyone else encountered this problem? Is there any way to force Xcode to reauthenticate with OpenAI or link it properly to a ChatGPT Plus account? System setup: • Mac mini (Apple M2, 16 GB RAM) • macOS Tahoe 26.0.1 • Xcode Version 26.0.1 (17A400) Here’s the error message I’m seeing:

Does Xcode 26 still support creating pull requests and/or viewing comments from GitHub pull requests associated with the current branch? This used to be possible, but I cannot get it to work with the current version of Xcode (26.0.1). The "Create Pull Request" menu item takes me to github.com directly, instead of presenting a nice UI menu; hence I'm wondering.

When I attempt to preview my code, I encounter an error message stating, “Cannot preview in this file: Failed to launch (App Name).” This issue is specific to this particular app. I attempted creating a new project, and that works fine. This is what it says in the diagnostics: | [Remote] JITError | | ================================== | | | [Remote] LLVMError | | | | LLVMError: LLVMError(description: "The file was not recognized as a valid object file")

Hello everyone, I'm encountering a frustrating issue with Xcode 26 and the iOS Simulator selection, and I'd appreciate any insight from the community. Problem Overview I have updated my Xcode to version 26.0. I have successfully installed the iOS 26 SDK and the iOS 26 Simulator runtime via Xcode's component settings. However, when I open an older, existing project, the device selection dropdown menu does not list the iOS 26 simulator. I can only select older versions, such as my locally installed iOS 18.6 simulator. Key Finding (Diagnosis) New Project Test: When I create a brand new Xcode project, the iOS 26 simulator is correctly available and runs as expected. Conclusion: This strongly suggests the issue lies with a specific configuration setting in the existing (old) project, rather than the Xcode installation itself. Troubleshooting Steps Taken I suspect a project-level configuration is somehow blocking the display of the new simulator. I've already checked: General -> Deployment Target: This is set to an older version, but theoretically shouldn't hide the simulator list. Build Settings -> Base SDK: This is set to the latest iOS SDK. Has anyone else experienced this behavior when upgrading projects to support iOS 26? What specific configuration files (e.g., .xcodeproj settings, Podfile configurations, or specific Build Settings) should I check to ensure my old project properly recognizes and displays the newly installed iOS 26 simulator? Any pointers or solutions would be greatly appreciated! Thank you.

I'm unable to debug on iPhone 12 running iOS 17 beta 3 via network. I'm running Xcode 15 beta 6 Device shows in devices and simulators and I can debug when connected with cable. However the "Connect Via Network" option is frayed out, oddly however the checkbox is ticked I'm developing a app using RoomPlan so network connectivity is a must for debugging Anyone else encountered this and know how to get around this problem Other devices running iOS 16 connect via network just fine

Hello, I'm seeing many errors like this in the Xcode debug console when I build and run my app: ERROR: Unrecognized attribute string flag '?' in attribute string "T@"NSString",?,R,C" for property debugDescription The app project makes heavy use of Logger(), and I suspect it is related to that logging in some way, but I haven't been able to narrow down the issue to specific log calls. I have Category, Subsystem and Timestamp enabled in the Xcode console, but none of those are displayed for this output. What causes this? Or how can I better narrow down the source?

Xcode 16.3 repeatedly logs a same message very frequently, as fast as a single thread can. I use Instruments and Console and find out the log is: Needs flush! by -[DNTBrotliDecoder decodeBytes:length:] in DNTDocumentationSupport. The call is on a single non-main thread. I've tried to clear caches and it seems doesn't change. Yet I don't know exact point when the logging starts since launch. Fortunately, this thread is dispatched at E cores, bringing approximately 2 watts of power load to my Mac. Environments: macOS 15.4 (24E248) Xcode 16.3 (16E140) M4 chip

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

If I use the method callAsyncJavaScript() my app will compile, but it won't run on older simulators. Specifically, in a brand new Storyboard project, I added this to `viewDidLoad(): let webView = WKWebView() webView.callAsyncJavaScript("1", in: nil, in: .page) { result in print("\(result)") } This runs fine with Xcode 16.3 targeting the iOS 18.4 simulator. It doesn't work if I target the iOS 18.3.1 simulator or the iOS 17.5 simulator. It does work on an iPhone 15 Pro running iOS 18.4 and it works on an iPhone 12 Pro running iOS 17.7.1. It goes without saying that this used to work on Xcode 16.2 and earlier, since my real project has been using that API for 3 or 4 years now.
