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.

Hi so i have a given project where I am trying to use components within the PhotosUI Framework with Xcode26 and Xcode26.0.1 Just for reference here is an attached screenshot This sample code compiled successfully with xcode16.4 and was in production. There is no change in the pbxproj file , all the build settings have remained the same. Attaching it for reference. project.pbxproj.txt While showing declarations of PHPickerViewControllerDelegate i get two options which is the same as in Xcode16.4 while browsing online found this reddit thread which is very similar https://www.reddit.com/r/Xcode/comments/1nkku20/my_project_wont_compile_after_xcode_26_update_due/ Pls help :)

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.

How to download the runtime simulators for the most recent Xcode 26 beta? The current download command I’m using doesn’t seem to work, and I’m encountering the following issues: The runtime simulator download command (xcodebuild) requires the version number to be specified explicitly. I’ve tried multiple variations of version names/numbers but haven’t been able to identify the correct naming convention used by Apple for the Xcode 26 beta simulator runtimes. $ xcodebuild -downloadPlatform IOS -exportPath ~/Downloads -buildVersion 26 Finding content...iOS 26 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 Finding content...iOS 26.0 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 beta Finding content...iOS 26.0 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0 beta" Finding content...iOS 26.0 beta is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0_beta" Finding content...iOS 26.0_beta is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0_beta Finding content...iOS 26.0_beta is not available for download.

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.

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.

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

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?

Environment: Xcode 26.3 RC macOS 26.3 (25D125) (Apple Silicon / arm64) Setup: Xcode > Settings > Intelligence > Claude Agent: Signed In (account status shows "Signed In") Model: Default Steps to reproduce: Open a new chat in Xcode's Coding Assistant Select "Claude Agent" from the agent dropdown (instead of "Claude Sonnet 4.5") Send any message (e.g. "HI") Expected result: Claude Agent responds normally. Actual result: The message is sent but immediately returns the error: "Your request couldn't be completed." 🚩I have an active Claude Code subscription with remaining usage. Running claude in Terminal works perfectly, confirming the subscription and quota are valid.

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.

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've connected my Claude account into Coding Intelligence and working properly (opening a web browsing and connecting my account), but when I press Claude Agent it sayes that I have to login againt. When I press the Account login with Claude.ai account, a web browser is opened, but it never finished the flow and I have an infinite spinner. Apple M2 Pro with macOS 26.2 (25C56)

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).

It has been two years since I wrote my a SwiftUI app, and I wanted to start again in Xcode 26. I can no longer see the attributes inspector when I select an element in the canvas. This was an Xcode feature that was very helpful as I am still a novice. Has this feature been deprecated in Xcode 26? And if not, please help explain how I can find and use it.

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.

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.

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.

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.
