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.

i need a pdf file to stage my app for screen shots for the market. icloud wont sync, cant drag files to the home screen or any screen, it just does not work.
i am at the end of my rope here, i just need some screen shots, my app is approved and ready
am i wrong>? is there a way to do this or is it just broken now in the name of (lazy) security?
edit--the more i read the more i angry and frustrated i get. this is broken and will not be fixed. i need to just workaround via email. so happy my second 100 dollar developer subscription bill is coming up!
Issue Report — Xcode 26.0 beta (17A5241e)
In Xcode 26.0 beta, double-clicking a file in the project navigator does not open it in a new tab as it normally should. Instead, it opens the file in the current editor window. Interestingly, Option-clicking a file still opens it in a new tab as expected.
I’ve confirmed that my Navigation preferences are properly set (see the attached screenshot), so this seems like a possible regression or bug in the current beta version.
Hi
I've downloaded the latest version of Xcode 14.2 but when I run the app in Simulator I can only test it on iOS16.2 Is there a way to run it in 16.3?
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.
Hi,
I'm testing out Xcode 16 beta and I have a couple of questions:
Is Swift Assist only available on Sequoia? I see that predictive code completion is per https://www.apple.com/newsroom/2024/06/apple-empowers-developers-and-fuels-innovation-with-new-tools-and-resources/, but I tried the beta on Sonoma and I'm not seeing it
Regarding Swift Assist - I understand that code is only used to process requests and never stored on servers, and Apple will not use it to train machine learning models. However, my company's security team may still decide that using Swift Assist is too much of a risk. How can we disable it across multiple developer machines?
Thank you!
Hey guys, I updated to macOS Tahoe and after that I tried installing Xcode 26, but I always get an error message saying it can’t complete the installation, both through the App Store and via direct download from Apple’s website. Is anyone else having this same issue?

Hi
One of the new Family Control API's requires the new "Family Controls App & Website Usage" capability but it appears to be missing in the latest Xcode beta (26.4 B2).
MacOS and iOS all running 26.4 Beta 3.
Does anyone know if we have to wait for Xcode 26.4 Beta 3 and it's associated SDK's for this one to become available?
I am not able to use the Debug Memory Graph tool as well as Leaks instrument inside Xcode to debug my project.
I'm running my project on physical iOS device on running 18.3 version and I tested the project on two different MacBooks running Xcode 16.3 and 16.1. On both the same problem persists. I have also reinstalled the project on the device and tried restarting all devices and cleared DerivedData. Nothing helped.

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times:
'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release
This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData.
My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).
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?
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.
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.

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.
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
Hi,
I’m seeing an unexpected change in how XCTFail behaves in UI tests after updating Xcode.
I use the following helper method:
`func waitForExistance(file: StaticString, line: UInt) -> Self {
if !(element.exists || element.waitForExistence(timeout: Configuration.current.predicateTimeout)) {
XCTFail("couldn't find element: \(element) after \(Configuration.current.predicateTimeout) seconds",
file: file,
line: line)
return self
} else {
return self
}
}`
In Xcode 16.4, this worked as expected:
– when an element wasn’t found, XCTFail was triggered, but the test continued running, allowing my retry logic to execute.
After updating to Xcode 26.1 / 26.2 - the test now immediately aborts after XCTFail, without executing the next retry.
The logs show:
`t = 113.22s Tear Down
t = 113.22s Terminate com.viessmann.care:81789
*** Assertion failure in -[UITests.Tests _caughtUnhandledDeveloperExceptionPermittingControlFlowInterruptions:caughtInterruptionException:whileExecutingBlock:], XCTestCase+IssueHandling.m:273
Test Case '-[UITests.Tests test_case]' failed (114.323 seconds).
Flushing outgoing messages to the IDE with timeout 600.00s
Received confirmation that IDE processed remaining outgoing messages`
It looks like XCTFail in Xcode 26 is now treated as an unhandled developer exception, which stops the test execution immediately, even when it’s called inside a helper method. This was not the case in earlier versions.
My questions:
Is this a regression in XCTest?
Or an intentional change in how XCTFail behaves in newer Xcode versions?
Should failures now be reported differently (e.g., using record(.init(type: .assertionFailure, …))) if I want to continue the test instead of aborting it?
I would like to restore the previous behavior where the failure is logged without terminating the entire test, so my retry mechanism can still run.
Has anyone else run into this after upgrading?
Thanks in advance!
If you’d like, I can also add recommended workarounds that actually work with Xcode 16.4 (e.g., replacing XCTFail with a non-terminating issue record).
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.
I just wanted to say thank you to the team that added coding assistance (Chat-GPT) to Xcode. I'm just learning SwiftUI and I love how it made suggestions to improve my app and shows me what it does and explains why it does what it does.

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.
