Using Xcode 26.1.1 on macOS 26.1 Tahoe, I noticed the ability to add a new value seems hidden or disabled. I'm unable to scrolling horizontally to view the rest of the values in each row and notice an overlap between the target properties and document types section.

Description: I’m noticing that the code coverage metrics in Xcode 26 are not accurate compared to earlier versions. In Xcode 15, the same set of unit tests shows around 38% coverage, but in Xcode 26, even though all the tests are running successfully (for example, the SegmentedUI test cases), the code coverage is displayed as 0%. Has anyone else observed this behavior in Xcode 26? Is there any known issue, workaround, or configuration change required to get the correct coverage report? Environment: Xcode 26 iOS 18 SDK Unit tests running under XCTest Any insights or suggestions would be appreciated.

I am trying to move over from AppCode/Intellij to Xcode. I am however having a hard time with the version control tools. I know that you can choose side-by-side when you activate "code review" and select single files. However, if you go into changes and view the list of files that have changed, i can only get inline-view to work. This is really frustrating to me, is there any way to get side-by-side also when you select a file from the changes list? Cheers

I am fixing bugs / extending a macOS app written by somebody else in Swift. I’ve made changes to it and debugging it, so breakpoints/rebuilding/debug print/change/rerun it isn’t a problem. But it is a multi-threaded, async app, and when I pause the running app, it will not display source code location in each thread where it is. I only get assembly. [and, yes, "Always Show Assembly" in OFF] It is inherent to async apps and threading that they spend most of their time waiting for the user to do something. Hence if you stop an app, you’ll almost always be in system code somewhere. But I think wanting to see the origin of completions that are pending is a legitimate question for somebody debugging (and trying to understand how the app works). Am I not aware some feature in Xcode / LLDB to reveal this?

Y'all, can we please get some way of increasing the font size in the Intelligence side pane? That tiny 10pt font (I'm guessing? Could be 8? I dunno) is KILLING my eyes. I don't want to increase the font size of EVERYTHING on my mac, just to increase the size of this one window that I need to read very closely.

I’m building a React Native 0.72.10 iOS app and hitting build errors. Environment: macOS: Apple M4, Sequoia 15.7.2 Xcode: 26.1.1 React Native: 0.72.10 Errors: Could not delete /Users/.../ios/build because it was not created by the build system Unable to write file '/Users/.../ios/build/Pods.build/Debug-iphonesimulator/...': Operation not permitted (Multiple Pods / React Native framework headers affected) What I’ve tried: bash rm -rf ios/build rm -rf ~/Library/Developer/Xcode/DerivedData xattr -w com.apple.xcode.CreatedByBuildSystem true ios/build pod deintegrate && pod install sudo chown -R $(whoami) ios/build Observations: ios/build is recreated automatically. Some files have com.apple.xcode.CreatedByBuildSystem: true. 3.Xcode have Full disk access authorisation. Why does Xcode fail to delete / write to ios/build even though it’s recreated automatically by the build system? Is this caused by Xcode itself, macOS permissions? Any recommended fix or workaround for these “Operation not permitted” errors?

Hello I'm wrapping my head around on how to properly set up xcode project to produce a static library ending up in file locations /usr/local/lib/libXXX.a and /usr/local/include/XXX/xxx.h so it can be used Unix style in other projects. If I put under Deployment Deployment Location: YES Installation Build Products Location: / Installation Directory: /usr/local/lib Skip Install: NO I get errors like warning: Stale file '/usr/local/usr/local/include/xxx.h' is located outside of the allowed root paths. and things like error: Cycle inside a single target; building could produce unreliable results. Installation Build Products Location: /usr/local/lib Installation Directory: / I get warning: Stale file '/usr/local/include/xxx.h' is located outside of the allowed root paths. but the library file is not put into /usr/local/lib (note /usr/local/lib and /usr/local/include are owned by my user and writeable) I could write an old style Makefile and have xcode call the makefile but there must be an easier way to do this. This is for a cross platform development so having it packaged into a Framework would not solve it neither.

Hi folks, I'm using Xcode 26.1.1 (17B100), but I don't see the ChatGPT plugin option when following the setup instructions below. Any ideas why this might be missing? https://developer.apple.com/documentation/xcode/setting-up-coding-intelligence

When using a Swift Build Plugin, the generated code definitions are available through autocomplete, but it is currently not possible to view them directly in Xcode using Option+click. An example of such a plugin is swift-openapi-generator. According to information from "Meet Swift Package plugins" from WWDC22 the generated code is stored with other build artifacts. It would be immensely helpful if there was support for viewing these intermediate files in read-only mode using Option+click. Currently, I have to resort to opening these files through Finder, or opening the project in VS Code where viewing the generated files using Cmd+click works without a problem. Am I missing something? If not, it seems like a big oversight that this is not supported to the same extent in Apple's own tools.

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?

I've made my updated icon and I try to import it to Xcode but it keeps crashing even if I clean the project/delete derived data or try to add through the Naivgation Controls. I've tried with the Xcode 26.2 beta too but it has the same issue.

LLVM Linker Crash on ARM64 with bfloat16 Symbols (Xcode 17.0.0) We're encountering a critical linker crash in Xcode 17.0.0 (clang-1700.4.4.1) on macOS 15.1.0 (Darwin 25.1.0) with Apple Silicon M3 Max when linking a pybind11 C++ extension against the MLX framework (v0.30.1). The linker consistently crashes with LLVM ERROR: No way to correctly truncate anything but float to bfloat during the linking phase, even though our code uses only integer types (int64, uint32) for BPE tokenization and never directly references bfloat16 types. Error Details: [100%] Linking CXX shared module _metal_trainer.cpython-312-darwin.so LLVM ERROR: No way to correctly truncate anything but float to bfloat clang++: error: unable to execute command: Abort trap: 6 clang++: error: linker command failed due to signal (use -v to see invocation) Reproduction: Install MLX framework: pip install mlx (any version with bfloat16 support) Create a minimal pybind11 extension that links against MLX: Compiler: AppleClang 17.0.0.17000404 Target: arm64-apple-darwin25.1.0 Flags: -std=c++17 -O2 -march=native Link against: libmlx.dylib (contains bfloat16 symbols) Run: cmake .. && make Linker crashes during final linking phase Root Cause: The LLVM ARM64 backend in Xcode 17.0.0 has a code generation bug when processing bfloat16 truncation operations during link-time. The crash occurs when the linker processes bfloat16 symbols from libmlx.dylib, regardless of whether the application code uses them. The error originates from LLVM's type legalization pass attempting to truncate bfloat16 values, but the ARM64 backend lacks a valid code path for this operation. Workarounds Attempted (all failed): Disabling LTO: INTERPROCEDURAL_OPTIMIZATION FALSE Linker flags: -Wl,-no_compact_unwind, -fno-lto Runtime symbol resolution: -undefined dynamic_lookup Compiler optimizations: Changed from -O3 to -O2 Impact: This blocks any C++ extension development that links against libraries containing bfloat16 symbols on Xcode 17.0.0. The issue does not occur on Xcode 16.x. Linker Crash Dump Location: /var/folders/gn/7_g6wy1j66b8z3lkywyrbsx00000gn/T/linker-crash-* Expected Behavior: Linker should successfully link the extension, or at minimum, gracefully handle bfloat16 symbols without crashing. Temporary Solution: Downgrade to Xcode 16.x or use Python-only implementations until this is fixed in a future Xcode release.

Is there a way to check or be notified for new Xcode beta versions? The only way I know is to manually keep checking the available betas web page to see if anything new is available (while also manually comparing it to the installed version). Or am I missing something?

Hello , after last update in Xcode, now the Apple Intelligence (Chat GPT) appears only what it was “changed” but don’t apply on code! Any solution?

I'm developing in Objective C with Xcode on a Mac exclusively to run on Mac and all of a sudden when I try to run I get the message: "a build only device cannot be used to run this target". If I go to the destination folder, the newly built app is there and runs from Finder, I just can't get it to run from within Xcode, which is inconvenient for testing. What setting am I missing or has changed? Up to now I could build and run with no problem.

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?

Hello, While setting up Xcode Cloud using Bitbucket, I encountered an issue with Source Control and providing access to the repository. The problem most likely stems from the fact that Bitbucket has updated its policy, and the use of app passwords is no longer available (at least for new ones). However, in Xcode → Settings → Source Control, the login flow still requires an app password, which makes it impossible to authenticate using the new API tokens. Attempting to authenticate via SSH also does not resolve the issue. After connecting to GitHub, I also tried to connect through the web version, but I'm getting the same message: "Bitbucket Cloud installation was incomplete." I received this same message when I first tried to connect through Xcode. This problem does not occur when connecting to GitHub. I would appreciate receiving feedback from the Apple team on this issue. System Info: Xcode: 16.2 (latest from App Store) macOS: Sequoia 15.1

Hey! I am writing type formatting scripts in Python for lldb, as described in https://lldb.llvm.org/use/variable.html#python-scripting. I'm trying to pass an environment variable to lldb from Xcode to determine the path to the scripts in the project root, so the project is not bound to some predetermined path. I am having trouble doing this in Xcode. What I have tried: lldbinit file Create a .lldbinit file in $(SRCROOT) with the following content: platform shell echo $SRCROOT. Set the path to the .lldbinit file in Edit Scheme... > Info > LLDB Init File ($(SRCROOT)/.lldbinit). Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables. entry-point breakpoint Add a breakpoint to the entry-point of the application. Set the Automatically continue after evaluating actions option. Add the action platform shell $(SRCROOT) or platform shell $SRCROOT. Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables. What I expect to happen: The first line of the debug console is a path pointing to $(SRCROOT) What actually happens: No path is output Is this functionality available in Xcode Version 26.0.1 (17A400)? Thanks in advance, Barnabas

I have a small, simple iOS project that doesn't use a lot of memory or libraries or anything. If I open my iOS project in XCode and run it on the iPhone 17 simulator, my memory consumption (as seen in Activity Monitor) goes into the yellow zone. Granted, I have some other apps open (Safari, Mail, Messages, the usual stuff that people run) but nothing especially demanding. Without XCode and the Simulator running, my memory consumption is only around 25% on the Activity Monitor graph. Is this expected behavior with Tahoe and iOS 26? I was able to work on my project without running out of RAM on this same computer for the past 4 years no problem. Now it seems I have a problem.

in my xcode project, i created a new package by going through File > New > Package, just like they said in https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages I have a package, but the problem is, whenever I made any changes in the package's source code, it never showed in the main project. I can import the package just fine, but the package does not show anything. no added apis, functions, nothing. Im using Xcode 26.0.1
