Hello, I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator. Steps to Reproduce: Create a new iOS project in Xcode 16 using the default iOS app template with the testing option checked. Run any test or UI test case by clicking the "Play" icon in the Test navigator. Xcode gets stuck at the "Testing" state indefinitely. Environment: macOS 15 beta 8 Xcode 16 beta 6 iOS 18 beta 7 simulator

I am using the latest version of Xcode 16, and I have created a GPX file in my project. However, I am unable to see or select the file to simulate the GPS location. I have attempted to uninstall and reinstall Xcode completely, but the issue persists. Has anyone encountered a similar problem? How can I resolve this? Thank you.

I have an orphaned asset folder taking up 9.13GB located at: /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/c0d3fd05106683ba0b3680d4d1afec65f098d700.asset It contains SimulatorRuntimeAsset version 18.5 (Build 22F77). Active Version: My current Xcode setup is using version 26.2 (Build 23C54). I checked the plist files in the directory and found what seems to be the cause of the issue: The "Never Collected" Flag: The Info.plist inside the orphaned asset folder explicitly sets the garbage collection behavior to "NeverCollected": <key>__AssetDefaultGarbageCollectionBehavior</key> <string>NeverCollected</string> The Catalog Mismatch: The master catalog file (com_apple_MobileAsset_iOSSimulatorRuntime.xml) in the parent directory only lists the new version (26.2). Because the old version (18.5) is missing from this XML, Xcode and mobileassetd seem to have lost track of it entirely. What I Have Tried (All Failed) Xcode Components: The version 18.5 does not appear in Settings -> Components, so I cannot delete it via the GUI. Simctl: xcrun simctl list runtimes does not list this version. Running xcrun simctl runtime delete 22F77 fails with: "No runtime disk images or bundles found matching '22F77'." Manual Deletion: sudo rm -rf [path] fails with "Operation not permitted", presumably because /System/Library/AssetsV2 is SIP-protected. Third-party Tools: Apps like DevCleaner do not detect this runtime (likely because they only scan ~/Library or /Library, not /System/Library). Has anyone found a way to force the system (perhaps via mobileassetd or a specific xcrun flag) to re-evaluate this folder and respect a deletion request? I am trying to avoid booting into Recovery Mode just to delete a cache file. Any insights on how AssetsV2 handles these "orphaned" files would be appreciated.

Hi, Ever since I updated to macOS Tahoe and started using Xcode 26 daily, I've run into an issue where it gets stuck very frequently when launching and running my app in the simulator. It happens with the main app target as well as when running unit tests. If I restart Xcode and the simulator app, it works fine again for a while, but after some use, it goes back to the same situation. In Activity Monitor, Xcode ends up at 1000% CPU utilization for a minute or more, basically rendering the simulator and the debugger stuck. If I untick the "Debug Executable" option in the scheme editor, it works fine as well. Anyone else run into the same situation, or are there any tips I can follow to fix this issue? It makes it really tedious to make changes and then be stalled for a minute or more to see the app run. I've restarted the Mac, erased the booted simulator as well. I'm on a MacBook Pro M4 Pro. Everything used to run fine before macOS Tahoe / Xcode 26 on my main device. In fact, I used to run macOS Tahoe / Xcode 26 beta versions on a separate partition without any problems.

With Xcode 14, the device selection on the bottom of the storyboard canvas has changed, and the iPhone 12 and 13 mini screens are no longer there, as well as there only being one model of iPad. Is there a way to add more devices to this section? I have simulators installed for these devices, and this is the way I've been checking compatibility so far, but this is not sustainable. I appreciate any help that you can give me.

Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts. Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated" Even after the simulator is launched I still het random "*** quit unexpectedly" alerts. Very annoying because the alerts deactivates the active window This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1 A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue Any idea how I can prevent this from happening? Update Every mentioned service crash happens in libswiftCore.dylib at 0x1929f3938 assertionFailure(:_:file:line:flags:) + 248

Since the latest Xcode has become available users in our environment are seeing this error any time they try to launch a simulator (Primarily iOS devices, but others provided the same error) We have tested on 16.4 and 26.0.1 with various suggested fixes including uninstalling and reinstalling all of Xcode. Nothing has helped.

xcode 15.2, mac m2 mini, 14.2.1 sonoma 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!

When test support code relies on production code, a diamond can occur. If this occurs across packages, it can lead to duplicated symbols and incorrect behavior at runtime despite no warnings at build time. This only occurs in Xcode and top-level application testing. This doesn't occur when the code being tested is in a separate package. I'm trying to understand how to correctly manage shared test support code which needs to access production code, or if this is the correct way and it is an Xcode bug. For a minimized example project, see https://github.com/rnapier/SupportCode. The setup includes three packages: Dependencies, which manages all the dependencies for the app and tests; Core which contains core logic and test support; and Feature, which relies on Core an contains feature-related logic and test support. Building this system causes Core.framework to show up three times in DerivedData: ./App.app/PlugIns/AppTests.xctest/Frameworks/Core_59974D35D_PackageProduct.framework ./App.app/Frameworks/Core_59974D35D_PackageProduct.framework ./PackageFrameworks/Core_59974D35D_PackageProduct.framework When unit tests are run, there is a collision on the symbol for Keychain: objc[48914]: Class _TtC8Keychain8Keychain is implemented in both /Users/ornapier/Library/Developer/Xcode/DerivedData/App-grdjljgevqofhqgflgtrqvhvbtej/Build/Products/Debug-iphonesimulator/PackageFrameworks/Core_59974D35D_PackageProduct.framework/Core_59974D35D_PackageProduct (0x100a98118) and /Users/ornapier/Library/Developer/CoreSimulator/Devices/216C441E-4AE5-45EC-8E52-FA42D8562365/data/Containers/Bundle/Application/7197F2F2-EB26-42FF-B7DB-67116159897D/App.app/PlugIns/AppTests.xctest/AppTests (0x1011002c0). One of the two will be used. Which one is undefined. This is not a benign warning. There are two distinct copies of _TtC8Keychain8Keychain and test cases will access one and the app will access a different one. This leads to mismatches when accessing static instances such as .shared. I believe this dependency graph should work, and it does work as long as the top-level testing system is a Swift module. But if it is the application, it builds successfully, but behaves incorrectly in subtle ways.

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?

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

The Files app in the iOS 18 beta simulator appears to be read-only. I am unable to: create folders copy files into it by dragging them from macOS safe files from safari I have been unsuccessful at finding a way to popular any file or folder in the Files app which is preventing me from testing some scenarios in my app where I import files using the files sheet. The earliest I tried was beta 3 and it still persists in beta 7. The iOS 17 simulator works fine in comparison. My mac is a 2019 macbook pro running Sonoma 14.5. To reproduce: New folder Launch Files app in iOS simulator Tap into "On my phone" From the top menu tap "New Folder" (nothing happens) Download a file Launch safari Find a file like a PDF to download Tap on the down arrow in the toolbar Files opens up with the filename in the textfield at the bottom The "Save" button is grayed out. Copy from macOS Open the Files app in iOS and browse to a local folder drag a file from the macbook onto the simulator the sheet appears with the filename in the text field The "Save" button is grayed out

Hello Team, I try to delete photo from Photos for that i used this method, [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ [PHAssetChangeRequest deleteAssets:@[assetToDelete]]; completionHandler:^(BOOL success, NSError *error) { }]; This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after. If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue. So what exact issue is there? Is it related to iOS or a method? Thanks, Ankur

Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed.

On devices and simulators with iOS 26.1, the animation does not work correctly (the initial and final screens are distorted). I use open class func transition(with view: UIView, duration: TimeInterval, options: UIView.AnimationOptions = [], animations: (() -> Void)?, completion: ((Bool) -> Void)? = nil) with options: .transitionFlipFromRight

Hello, I am currently working on personal project based on Matter. I need to create a Basic Video Player as specified in Matter's standard embedding the Media Playback Cluster. I went through the reading of how Apple now supports Matter as a standard : linkText My understanding of the following schematic, is alongside : HomeKit Accessory Protocol (HAP) Framework API Related HAP accessories underneath the homeKit framework. Developpers also find under the Homekit framework : CHIP (Connected Home IP) Framework API Related Matter accessories this time Both types of accessories/devices can be commissioned in the HomeKit ecosystem seemlessly. Each framework has it's documentation : HAP : https://developer.apple.com/documentation/homekit/hmhomemanager CHIP : https://developer.apple.com/documentation/matter I want through the process of installing XCode and the HomeKit Accessory Simulator. In the list of HomeKit Accessories I did not see any Media related devices : The list of currently supported devices is limited as I read here and will be enriched with time : https://support.apple.com/en-us/102135#:~:text=The%20Home%20app%20currently%20supports,%2C%20temperature%2C%20and%20humidity). In the meantime, as I read the matter documentation, I read several references made to the Media Playback : https://developer.apple.com/documentation/matter/mtrclustermediaplayback https://developer.apple.com/documentation/matter/mtrbaseclustermediaplayback https://developer.apple.com/documentation/matter/clusters#Interacting-with-the-Media-Playback-cluster My questions are : Are Matter Basic Video Players, (Media Playback) supported in HomeKit ? Why aren't they listed in HomeKit Accessory Simulator ? How can I add a Basic Video Player in HomeKit and display it's Media Playback controls once I have added the device to HomeKit ? Thank you for your Answer. Regards David

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.

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.

I'm getting following message when launching #Playgrounds canvas with Xcode 26 beta 4. Here are things I've tried: Reinstall Xcode Reinstall components Removed derived data Run Disk Utility to fix permissions Tried to change Default Actor Isolation, Approachable Concurrency Changed around settings on Schemes: Run: Options and Diagnostics Created brand new project with default settings. Filed FB19003005 in Feedback Assistant. I'm surprised to see that I didn't see any posts on this during my search. So this could be isolated matter just to me.
