I have a question concerning Xcode version 26. Ever since I installed this version on my Mac, I have been experiencing issues with the StoreKit configuration file. The Simulated StoreKit Failures check boxes and selections are all grayed out. Once in a while, I see a pop-up stating "The document 'TaConfig.storekit' could not be autosaved. The file has been changed by another application. The pop-up Save as... points to where my config file is located, but the config file is grayed out. I thought maybe the directory where the file is located is write protected, but I have been able to save other files to the same directory. The Edit Scheme... -> Run -> Options has the StoreKit Configuration set for my file TaConfig.storekit. It feels like there is an option somewhere that I'm missing.

I was encountering visual artifacts in my Unity game only on iOS devices and wanted to use the Metal Debugger to diagnose it. However, it seems to only capture static noise which is not helpful as shown below For reference, this is a frame of the visual artifact and also the location where I asked Metal to capture the frame Am I missing any settings in Unity/Xcode?

When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?

Hi, I recently updated my Mac to macOS Sequoia 15.7.2, and then updated my Xcode packages right afterward. However, when I try to open Xcode, I receive the message: “You can’t open the application because it is being updated.” I contacted Apple Developer Support (software) by phone and went through their troubleshooting steps, but the issue persists. They confirmed that everything appears fine on their end. In System Settings, both macOS and Xcode show as fully up to date. However, when I manually check in the App Store, it says Xcode needs to be updated. When I press Update, I get the following error: “Xcode could not be installed. Please try again later.” I’m fairly new to Xcode, but it seems there may be an incomplete update or verification loop preventing the installation from finishing properly. Could you please advise on how to resolve this so I can open Xcode again?

Hello, I'm having issues trying to Install the iOS 26.0 + iOS 26.0.1 Simulator on Xcode 26.0.1. I'm getting this error Download failed as the server said it was a bad request. (Asset download for com.apple.MobileAsset.iOSSimulatorRuntime 39434c057e7b18d2f1447aeb47e9bb6b6dbff077) I have attached the full logs. Thanks xcode-error.txt

prior to upgrading from an M1 to M5 I could run the Mac on iPad via Xcode After upgrading to a M5 I keep getting dyld[88241]: Library not loaded: @rpath/APP.debug.dylib Referenced from: <207ED9FB-3483-3063-B9BC-81EC3BCB34AF> /private/var/folders/54/cwf8kbhx48j71vk_z3zm0t_m0000gn/X/471D0939-4FD4-59C7-8DB5-641DB2A36911/d/Wrapper/App.app/App Reason: tried: '/Users/xxx/Library/Developer/Xcode/DerivedData/project-esgmvpqlktgtvldltqmcjtupefnh/Build/Products/Debug-iphoneos/App.debug.dylib' (no such file), '/usr/lib/system/introspection/App.debug.dylib' (no such file, not in dyld cache), ... bunch more path searching..

We are seeing repeated occurrences of the following log line in test runs triggered via .xctestrun files on iOS 26: IDERunDestination: Supported platforms for the buildables in the current scheme is empty. This line is printed n number of times after a test fails, significantly increasing test execution duration (2–3 minutes extra in some cases). The issue does not occur when tests are built and run together from Xcode directly — it’s specific to .xctestrun-based executions using xcodebuild test-without-building. Steps to Reproduce: Use Xcode 26 to build a sample XCTest target (we used a simple UI test project). Locate the generated .xctestrun file under DerivedData/.../Build/Products/.... Run tests using: xcodebuild -xctestrun /path/to/sample.xctestrun \ -destination "id=<device_id>" \ test-without-building Observe the logs during test failure. Observed Behavior: The log line IDERunDestination: Supported platforms for the buildables in the current scheme is empty appears multiple times. The test cleanup and teardown phase takes significantly longer (2–3 minutes). Expected Behavior: The log should appear once or not at all. Test cleanup time should remain consistent. Additional Information: Affects only iOS 26 devices and .xctestrun-based runs. Not reproducible on iOS < 26. Xcode 26 and 26.x beta versions tried. Reproducible both locally and on CI systems using real devices. Same .xctestrun file, when used on older OS versions, does not cause delay.

The MXCrashDiagnostic and MXHangDiagnostic reports are not being returned via MXMetricManager on the next app launch in iOS 17.2, 17.3, 17.4, and 17.5. This issue prevents collection of crash and hang diagnostics through the MetricKit framework, which worked as expected on earlier and later (18, 26) iOS versions. Steps to Reproduce:- Integrate MetricKit in an iOS app using: MXMetricManager.shared.add(self) and implement: func didReceive(_ payloads: [MXDiagnosticPayload]) Install and run the app on a device running iOS 17.2 or later. Cause a crash or hang scenario (e.g., dereference a null pointer or block the main thread). Relaunch the app after the system terminates it. Observe the callback for diagnostic payloads. Expected Behavior MXMetricManager.shared.didReceive(_:) should be invoked on the next launch, returning diagnostic payloads that include MXCrashDiagnostic or MXHangDiagnostic objects. Actual Behavior: No diagnostics are returned on subsequent launches. didReceive(_:) is not triggered, or the diagnostic payloads array is empty. This behavior is reproducible across multiple devices and iOS versions (17.2–17.5). iOS Versions: 17.2, 17.3, 17.4, 17.5 Devices Tested: iPhone 14, iPhone 15 Pro Xcode Version: 15.2 / 15.3 Framework: MetricKit Diagnostic Type: Crash and Hang

I still use my own Info.plist, and I run a script as the last step of my builds to modify the final built Info.plist to have information about the build, like date, machine, git build count, etc. Works fine on latest Xcode 26.0.1 for archive builds, but on DEBUG builds to an attached device Xcode overwrites my processed plist with a copy of the original unmodified build, unless I first do a Clean Build Folder. Any ideas on how to fix this? Annoying, but not critical

Opened a FB already (FB20928652) but wanted to check here if anybody has seen similar or has better workarounds. xcresulttool merge appears to crash immediately after launch in Xcode 26.1 (and in 26.2b1). It does so regardless of any inputs passed in; the crash appears to be during argument parsing before any other logic is run, so it's not contingent on inputs. Working example from 26.0.1 (passing in arbitrary strings for a minimum-reproducible-case, so we expect to see an error message) : % /Applications/Xcode-26.0.1.app/Contents/Developer/usr/bin/xcresulttool merge --output-path a b c Error: File or directory doesn't exist at path: b. Usage: xcresulttool <subcommand> See 'xcresulttool --help' for more information. The same example crashes in 26.1: /Applications/Xcode-26.1.0.app/Contents/Developer/usr/bin/xcresulttool merge --output-path a b c zsh: trace trap /Applications/Xcode-26.1.0.app/Contents/Developer/usr/bin/xcresulttool merge Again, this does crash in real use cases as well, the arbitrary strings are just for quick reproduction. The stack trace appears to be during argument parsing (which from a quick look, did indeed change between 26.0.1 and 26.1). On 26.1+, garbage data seemingly gets passed to AbsolutePath.init. * thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1 * frame #0: 0x00000001002c6748 xcresulttool-26.1`normalize(absolute:) frame #1: 0x00000001002c6438 xcresulttool-26.1`AbsolutePath.init(_:) + 28 frame #2: 0x000000010005a2c0 xcresulttool-26.1`Merge.run() + 372 frame #3: 0x000000010005b180 xcresulttool-26.1`protocol witness for ParsableCommand.run() in conformance Merge + 12 frame #4: 0x000000010011d3e4 xcresulttool-26.1`dispatch thunk of ReadableStream.close() + 16 frame #5: 0x000000010000148c xcresulttool-26.1`main + 156 frame #6: 0x00000001804d5d54 dyld`start + 7184 The only workaround we've found is to keep using 26.0.1's copy of xcresulttool, though that's obviously not ideal.

I'm working in a constrained environment where sending source is not an option if any part of it is stored in outside systems. However, I also have some projects which don't have these constraints which led me to these questions. Thanks! Can I disable intelligence per project or workspace? Is any project data sent if intelligence is enabled but I'm not typing any requests in the coding assistant? Is source/metadata persisted in any way when using the ChatGPT mode without an account?

Hello, I'm encountering a persistent issue when building my project with Xcode 26 and iOS 26. The console shows errors related to font file references that don't actually exist in my project. GSFont: file doesn't exist - "file:///private/var/containers/Bundle/Application/...../HiraginoKakuGothic.ttc" After investigation, I found that the issue originates from XIB files incorrectly referencing HiraginoKakuGothic.ttc: <customFonts key="customFonts"> <array key="HiraginoKakuGothic.ttc"> <string>HiraginoSans-W3</string> </array> </customFonts> The problem appears to be triggered when setting UILabel fonts to "ヒラギノ角ゴシック W3 16.0" in Interface Builder, which causes the XIB to reference HiraginoKakuGothic.ttc. Interestingly, when I create a new project and use the same fonts ("ヒラギノ角ゴシック W3 16.0"), it does NOT automatically reference HiraginoKakuGothic.ttc. Here's what I've tried: ①Changed both UILabels' fonts to system font ②Verified in XIB Source Code that the .ttc references were gone ③Cleaned Build Folder ④Cleared DerivedData ⑤Restarted Xcode ⑥Set the labels back to "ヒラギノ角ゴシック W3 16.0" ⑦Checked XIB Source Code again - the non-existent .ttc references reappeared Even if I manually remove the customFonts references from the source code, they get regenerated as soon as I make any font changes in Interface Builder. I've also noticed that Xcode 16.1 has the same underlying issue, though it doesn't produce the console errors that Xcode 26 does. This seems to be a long-standing XIB issue, possibly related to reference caching. While new projects aren't affected, existing projects continue to maintain these incorrect references. My questions: How can I permanently resolve this issue in my existing project? What's the potential impact of these incorrect font references? Is there a way to clean up these cached references without affecting the rest of the project? Any insights or workarounds would be greatly appreciated. Thank you.

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.

ChatGPT in Xcode 26.1 is super slow for me. What used to complete in a batter f seconds is now taking tens of minutes. Context: M2 Pro MBP, Xcode 26.1, macOS 26.1. CPU stays under 50% while ChatGPT returns. Using the minimal setting. Tried restarting, have verified I have nothing running Electron, no other apps are running. ChatGPT returns fast for the displayed content but the preview window where it renders code per line takes a few seconds per line.

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. M2 Pro MBP, macOS 26.1.

Since upgrading my iPhone 13 Pro Max to iOS 26, apps have become nearly impossible to debug. The recent update to iOS 26.1 has made this even worse. Going from app start to a fully rendered & responding screen takes <1 second on a Debug build when no debugger is attached, but with the debugger attached I get these times (measured manually with a stopwatch): First render: <1 second without debugger 5 seconds on USB debugger 30 seconds on wireless debugger Data loaded from webserver and UI responding: <1 second without debugger 19 seconds on USB debugger 5 minutes on wireless debugger! Doing an online speed test reports 55 Mbps for the phone and 60 Mbps on the MacBook, so I doubt it's my WiFi. Having a debugger attached used to make minimal difference on iOS 18, but the performance has tanked completely since the last major release. What happened?
