Unable to launch tests in Xcode 26
I am trying to upgrade my app to use Xcode 26 and I cannot get my tests to launch. I am trying to launch tests to the simulator, and I always get this error after 300 second timeout: "encountered an error (The test runner hung before establishing connection.)" There are no other errors getting logged. I can run to the same simulator just fine, and in Xcode 16 the tests launch with no issues. The tests also run fine on an actual iPhone. Thanks in advance.

Xcode always shows error "Error Downloading Crash Log Information" when trying to download crash logs
For a couple of months now I haven't been able to see new crash reports for my App Store apps in Xcode. I see the list of crash reports in the Organizer, but selecting any of the new ones always shows the same error message: Error Downloading Crash Log Information: An error occurred preventing Xcode from downloading crash log information. "my.email at domain.com" failed with error: There was a failure decoding response: (HTTP 500, 20364 bytes) The data couldn't be read because it isn't in the correct format.. Pushing the Reload button makes the view load for a bit, but then the same error appears again. Since I want to keep fixing crashes in my apps as fast as possible, is Apple aware of the issue and working on a fix? I don't know if this is a Xcode or App Store Connect issue. I would have expected this issue to be fixed with the newest Xcode version 26.5, but it's still happening. I opened FB22589345 on April 23, but got no response so far.

macOS 26.0 Tahoe + Xcode 26.0.1 Simulator causes system-wide audio distortion
After upgrading to macOS 26.0 Tahoe and Xcode 26.0.1, I’ve noticed an issue with audio playback whenever the iOS Simulator is running. Device: MacBook Pro 13" (2020, Intel, 16GB RAM, 500GB SSD) Issue: Any sound played on the Mac (system sounds, music, videos) begins to break/distort once the Simulator is active. App Sounds: If the app running inside the Simulator plays audio, that audio also breaks/distorts. Previous Version: This issue did not occur on macOS Sequoia 15 or with Xcode 16. Everything was working fine before the upgrade.

Why is Xcode so slow and bad?
I just want to rant why is Xcode such a bad ide and I wish Apple can do a better job on Xcode. Here's why: The preview is so slow. Most of the times it's just faster for me to test on a real device. It is so slow, and many times I need to force quite after it's being unresponsive for sometimes. When I'm working on larger projects, the loading time becomes extremely slow especially when there's other clients that might be reading the same files like a Git client or simply iCloud. The breakpoint is so slow. I don't know why, is it an iOS thing? But when I'm on ASP.Net the breakpoints are super fast. For Xcode it takes a long time to pause and show data. It's so big I don't know why it is so hard for Apple to make their ide better. The community has been unsatisfied with Xcode for a long time. There's many tricks on the internet that you can find to help you resolve some issues with your project that's actually related to Xcode. Instead of using these tricks, Apple should just fix these issues. Learn from Intellij!

Xcode 26.3 not rendering Unicode/Emoji in Simulator or Canvas
I'm based in Australia, and am having the following issue. After leaving this message I received another response from someone else who is also havign the same issue, I've pasted that too. I'm quite surprised to not see it mentioned, could be local to language settings or something. Here is the issue: Folk, I am having an issue where Xcode 26.3 with the new iOS26.2+26.3.1 Simulator update installed doesn’t render Unicode characters in the Canvas or in Simulator. They do render when running direct to a device. I’ve reset devices inside Simulator, cleared Derived Data, cleaned Build Folders etc but to no avail! Is anyone else seeing this, I can’t find a mention anywhere!! Thank you in advance. Yep. Same here. Can't see emojis on the emoji picker keyboard.

Request: Option to Position Coding Assistant on the Right Side in Xcode
Dear Xcode Team, Please consider adding an option to position the Coding Assistant on the right side of the editor. Currently, when the assistant panel is open, it makes it difficult to access the Project Navigator at the same time. Having the ability to move the Coding Assistant to the right side would allow developers to keep the Project Navigator visible while interacting with the assistant, improving workflow and efficiency. Thank you

iOS15 on Xcode26 / Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier
Below is an English version of your post, ready to copy-and-paste into the Apple Developer Forums: I’m seeing a crash in Xcode 26 beta 3 whenever the StoreKit symbol SKStoreProductParameterAdNetworkSourceIdentifier is present while running on an iOS 15 simulator. Steps to reproduce Install Xcode 26 beta 3. Create any iOS app and run it on an iOS 15 simulator (device model doesn’t matter). Add the following code anywhere and run: override func viewDidLoad() { super.viewDidLoad() if #available(iOS 16.1, *) { print("SKStoreProductParameterAdNetworkSourceIdentifier: \(SKStoreProductParameterAdNetworkSourceIdentifier)") } } The project builds successfully, but before the #available(iOS 16.1, *) check is reached, the app crashes with: Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier When I build the same project with Xcode 16.4 and launch it on an iOS 15 simulator, it runs without crashing. Investigation so far Because SKStoreProductParameterAdNetworkSourceIdentifier is just an NSString, I could substitute the string literal "SKStoreProductParameterAdNetworkSourceIdentifier" as a temporary workaround, but that doesn’t feel like a proper fix. The symbol is still declared in both SDKs: /Applications/Xcode-16.4.0.app/.../StoreKit.framework/Headers/SKAdNetwork.h:48: SK_EXTERN NSString * const SKStoreProductParameterAdNetworkSourceIdentifier API_AVAILABLE(ios(16.1)) API_UNAVAILABLE(macos, watchos, visionos); /Applications/Xcode-26.0.0-Beta.3.app/.../StoreKit.framework/Headers/SKAdNetwork.h:48: SK_EXTERN NSString * const SKStoreProductParameterAdNetworkSourceIdentifier API_AVAILABLE(ios(16.1)) API_UNAVAILABLE(macos, watchos, visionos); So the symbol hasn’t been removed in the beta SDK. Given that the code is wrapped in #available(iOS 16.1, *), I don’t believe the sample itself is at fault. Questions Could this be a bug in Xcode 26’s availability checking or linker? Has anyone else encountered the same issue or found a more robust workaround? Any insights would be greatly appreciated.

Xcode 26.3 Codex Account just spinning
I have the new Xcode 26.3 running on an Intel MBP macOS 26.2 I have clicked to download Codex in the Xcode settings, then under the Intelligence section I select Codex but where it says "ChatGPT Account" there is a spinner that never ends. I suspect it is meant to show a Sign In button. I don't see any documentation to suggest this shouldn't work on Intel, so what gives? My "ChatGPT in Xcode" section is successfully signed in, and i've tried signing that out.

Linker trying to link Metal toolchain for every object file on Catalyst
When building our project for Mac Catalyst with Xcode 26.2, we get this warning almost a hundred times, once for every object file: directory not found for option '-L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' Somehow, every Link <FileName>.o build step got the following parameter, regardless if the target contained Metal files or not: -L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst The toolchain is mounted at this point, but the directory usr/lib/swift/maccatalyst doesn't exist. When building the project for iOS, the option doesn't exist and the warning is not shown. We already check the build settings, but we couldn't find a reason why the linker is trying to link against the toolchain here. Even for targets that do contain Metal files, we get the following linker warning: search path '/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' not found Is this a known issue? Is there a way to get rid of these warnings?

Xcode 16 issues with mac virtualisation
I have created a virtualised Mac machine where I am running the latest Xcode version 16.4 with macOS Sequoia as the base image. While running XCTest tests, I am observing a clear difference in behaviour between virtualised and non-virtualised setups. Below is the command I am using to run the tests: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -xctestrun /Users/ltuser/290103613/xcui.xctestrun -destination "platform=iOS Simulator,id=79A5F8CC-4A2E-4C91-895D-AE97E25CB824,arch=arm64,OS=18.0" test-without-building "-only-testing:ClassName/MethodName/testName" -derivedDataPath /Users/ltuser/290103613/Archive -verbose IDELogLevel=debug IDETestLogLevel=debug ONLY_ACTIVE_ARCH=YES Observed Issue On virtualised hosts: Every XCTest is executed twice This happens for both passed and failed tests The behaviour is consistent across all virtualised machines On non-virtualised (bare-metal) Macs: Tests execute only once, as expected Debugging Steps Taken Multiple destination suspicion Initially, I noticed the following warning: --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } This raised suspicion that tests might be running twice due to multiple matching destinations. Destination narrowed down I then explicitly restricted the destination to a single simulator UDID, after which: The warning disappeared However, the issue still persists Tests continue to run twice on virtualised hosts Version Comparison Xcode 16.4 + macOS Sequoia (virtualised) → Tests run twice Xcode 15.x (same setup otherwise) → Tests run once Questions Has anyone else faced this issue with Xcode 16.x on virtualised macOS? Is this a known issue with Xcode 16 + Virtualisation? Is there any recommended workaround or configuration change to avoid duplicate test execution? I am currently blocked on this issue and would appreciate confirmation on whether this is an Xcode or virtualisation-related problem. Thank you.

iOS15 on Xcode26 / Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier
Below is an English version of your post, ready to copy-and-paste into the Apple Developer Forums: I’m seeing a crash in Xcode 26 beta 3 whenever the StoreKit symbol SKStoreProductParameterAdNetworkSourceIdentifier is present while running on an iOS 15 simulator. Steps to reproduce Install Xcode 26 beta 3. Create any iOS app and run it on an iOS 15 simulator (device model doesn’t matter). Add the following code anywhere and run: override func viewDidLoad() { super.viewDidLoad() if #available(iOS 16.1, *) { print("SKStoreProductParameterAdNetworkSourceIdentifier: \(SKStoreProductParameterAdNetworkSourceIdentifier)") } } The project builds successfully, but before the #available(iOS 16.1, *) check is reached, the app crashes with: Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier When I build the same project with Xcode 16.4 and launch it on an iOS 15 simulator, it runs without crashing.

Linker trying to link Metal toolchain for every object file on Catalyst
When building our project for Mac Catalyst with Xcode 26.2, we get this warning almost a hundred times, once for every object file: directory not found for option '-L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst' Somehow, every Link <FileName>.o build step got the following parameter, regardless if the target contained Metal files or not: -L/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.48.0.UZtKea/Metal.xctoolchain/usr/lib/swift/maccatalyst The toolchain is mounted at this point, but the directory usr/lib/swift/maccatalyst doesn't exist. When building the project for iOS, the option doesn't exist and the warning is not shown. We already check the build settings, but we couldn't find a reason why the linker is trying to link against the toolchain here.

Below is the command I am using to run the tests: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -xctestrun /Users/ltuser/290103613/xcui.xctestrun -destination "platform=iOS Simulator,id=79A5F8CC-4A2E-4C91-895D-AE97E25CB824,arch=arm64,OS=18.0" test-without-building "-only-testing:ClassName/MethodName/testName" -derivedDataPath /Users/ltuser/290103613/Archive -verbose IDELogLevel=debug IDETestLogLevel=debug ONLY_ACTIVE_ARCH=YES Observed Issue On virtualised hosts: Every XCTest is executed twice This happens for both passed and failed tests The behaviour is consistent across all virtualised machines On non-virtualised (bare-metal) Macs: Tests execute only once, as expected Debugging Steps Taken Multiple destination suspicion Initially, I noticed the following warning: --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } This raised suspicion that tests might be running twice due to multiple matching destinations. Destination narrowed down I then explicitly restricted the destination to a single simulator UDID, after which: The warning disappeared However, the issue still persists Tests continue to run twice on virtualised hosts Version Comparison Xcode 16.4 + macOS Sequoia (virtualised) → Tests run twice Xcode 15.x (same setup otherwise) → Tests run once Questions Has anyone else faced this issue with Xcode 16.x on virtualised macOS? Is this a known issue with Xcode 16 + Virtualisation? Is there any recommended workaround or configuration change to avoid duplicate test execution? I am currently blocked on this issue and would appreciate confirmation on whether this is an Xcode or virtualisation-related problem. Thank you.

Xcode 26 Beta 4 Build Failures
We are trying to track down some build failures that started happening only in our Jenkins CI environment. error: Failed to decode version info for '/Applications/Xcode.app/Contents/Developer/usr/bin/actool': The data couldn’t be read because it is missing. (stdout: '<?xml version="1.0" encoding="UTF-8"?> [2025-07-30T19:21:18.479Z] <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> [2025-07-30T19:21:18.479Z] <plist version="1.0"> [2025-07-30T19:21:18.479Z] <dict> [2025-07-30T19:21:18.479Z] <key>com.apple.ibtool.version</key> [2025-07-30T19:21:18.479Z] <dict> [2025-07-30T19:21:18.479Z] <key>bundle-version</key> [2025-07-30T19:21:18.479Z] <string>24112</string> [2025-07-30T19:21:18.479Z] <key>short-bundle-version</key> [2025-07-30T19:21:18.479Z] <string>26.0</string> [2025-07-30T19:21:18.479Z] </dict> [2025-07-30T19:21:18.479Z] </dict> [2025-07-30T19:21:18.479Z] </plist> [2025-07-30T19:21:18.479Z] ', stderr: '' Key facts we've noted: Locally I cannot reproduce the problem We did not see this problem with previous Xcode 26 betas If I remote into the machine and run build commands from the command line I cannot reproduce the problem The very first build succeeds, every build after that on this machine fails from jenkins actool --version is spitting out the version information for ibtool, but only in the context of running from a jenkins agent. If I run this locally or if I remote into the CI machine and run this from the terminal I cannot reproduce this behavior. Command line tools appear to be installed, xcode-select --install fails if I try to do it from the command line. We've tried to recreate the build agents for this jenkins environment exactly as they were for all previous betas and xcode versions, and still get this behavior.

Use CFBundleVersion instead of CI_BUILD_NUMBER
Is there a way to use CFBundleVersion instead of CI_BUILD_NUMBER from XCode Cloud's workflow on Web ? We would like to have control over the major and minor version numbers of the build from the workflow.

XCode crashing in VIM Mode while deleting the complete line with double tap of "d"
I have been using Xcode Version 26.1.1 on macOS Tahoe Version 26.1. In VIM mode, whenever I quickly tap d twice, to delete the complete line, most of the time Xcode crashes. Is anyone else facing this issue? Should I move to any older version of Xcode or any other solve for this?

Xcode cloud time out issue
We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.
