Some Macs recently received a macOS system update which disabled the simulator runtimes used by Xcode 15, including the simulators for iOS, tvOS, watchOS, and visionOS. If your Mac received this update, you will receive the following error message and will be unable to use the simulator: The com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime is not available. Domain: com.apple.CoreSimulator.SimError Code: 401 Failure Reason: runtime profile not found using "System" match policy Recovery Suggestion: Download the com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime from the Xcode To resume using the simulator, please reboot your Mac. After rebooting, check Xcode Preferences → Platforms to ensure that the simulator runtime you would like to use is still installed. If it is missing, use the Get button to download it again. The Xcode 15.3 Release Notes are also updated with this information.

Hello: I have Xcode running and I have already downloaded the Vision Pro simulator, but it doesn't open. It even appears open within the Xcode application as an internal window and it works... but it doesn't allow me to open the simulator app. I need help, please. I'll leave a couple of pictures below that explain it better.

I installed xcode 16 and both Predictive Code Completion Model and iOS 18.0 Simulator Failed Download. I can live without the code completion, but I can not get any Simulator to install.

I have updated my firebase with the latest version, but on simulator, apple log in and parsing from firebase server is not working on iOS 18 when working fine on the actual test device. However iOS 17 simulator works perfect as X-Code 15. And previews are not working as well with my current app coding, which was coded in previous X-code 15. Is there any API changes? Any help? Or 18.1 might fix this bug?

Since its update to iOS 18.0, I have not been able to use the Simulator in Xcode at all. It is stuck loading for a very long time, and then it crashes. I managed to get it to start once, but it used up all of my system's memory immediately. I have not had any problems with the Simulator before the iOS 18.0 update. Additionally, after the Simulator crashing, the StoryBoard usually stops working as well, until I restart Xcode. (I use an M1 MacBook Air with 8GB of RAM)

When tapping on "password" in the accessory view above the keyboard, no password manger is opened. The keyboard just closes and re-opens. I have made sure a password exists and is available to be used. I have replicated this within my own app, but also from within the Settings app on the simulator (see attached gif) so I am confident it is not a coding issue on my side. I have replicated it on both iOS 17 and iOS 18 I am using Xcode Version 16.0 (16A242d) I am running macOS Sonoma Version 14.7 (23H124) I am fairly confident I have not experienced this when working on another clients app. I was using Xcode 15 for that so not sure if this is something introduced with Xcode 16.

Hi team, I'm trying to test facid enroll the faceid via simulator [i have injected the command in driver.executeScript option and i have notice in logs enrollment has changed. coreauthd: (DaemonUtils) [com.apple.LocalAuthentication:Server,Biometry] BK notification received: com.apple.BiometricKit.enrollmentChanged in further logs noticed Biometricsupport.framework is missing in xcode file locations logs for your reference " lstat of /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/BiometricSupport.framework/Info.plist failed: No such file or directory)" any thoughts on missing library? I have tried Faceid and Authorize apple pay in UI also i dont see any action triggered. later i have identified not sure is that because of the Biometric framework missing in the xcode folder.

I’m using Xcode 16 on an M1 Pro and experiencing overheating issues. It seems like Apple rushed the release without addressing glitches that cause the laptop to overheat, which can directly affect battery life, decreasing its performance and, in turn, lowering the value of the Mac. I really dislike this from Apple. We pay a lot for their products, and issues like these devalue them.

I just upgraded to Version 16.0 (16A242d) and unfortunately the App that used to run perfectly fine on Xcode 15 is now broken. It crashes right after showing the Launch Screen on the Simulator. Here's the formatted error message in the Console: dyld[80159]: Library not loaded: @rpath/AppName-iOS.debug.dylib Referenced from: <App ID> /path/to/AppName-iOS.app/AppName-iOS Reason: tried: '/path/to/DerivedData/AppName-iOS.debug.dylib' (no such file), '/path/to/CoreSimulator/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/introspection/AppName-iOS.debug.dylib' (no such file), '/path/to/AppName-iOS.app/AppName-iOS.debug.dylib' (code signature not valid for use in process: Trying to load an unsigned library), '/path/to/DerivedData/PackageFrameworks/AppName-iOS.debug.dylib' (no such file), '/path/to/AppName-iOS.app/Frameworks/AppName-iOS.debug.dylib' (no such file), '/path/to/CoreSimulator/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/AppName-iOS.debug.dylib' (no such file) For some reason the Library is unsigned and I've checked all the settings with no luck.

Hi there! Was there a change in Xcode regarding incremental builds / updating an active Simulator with a new build? We use xcodebuild to manage our internal build framework and out of the sudden, incremental builds are not launched anymore and the Simulator is stuck waiting for the new build to be launched. This was not happening for the last 10+ years. If there is an xcodebuild flag and/or guide of this new behavior, it would help a lot. Thanks everyone!

We have some third-party SDKs do not support arm64 simulator, so we excluded arm64 for Any iOS Simulator SDK in Excluded Architectures. But in this case, ASWebAuthenticationSession will display abnormally. We submitted FB14853757 during the beta period, but have not received any response. This issue still exists in the official version. I hope it can be resolved. Thank you!

Hello, I'm getting an unknown, never-before-seen error at application launch, when running my iOS SpriteKit game on the iOS 18 arm64 simulator from Xcode 16.0 (16A242d) — AudioConverterOOP.cpp:847 Failed to prepare AudioConverterService: -302 This is occurs on all iOS 18 simulator devices, between application(_:didFinishLaunchingWithOptions:) and the first applicationDidBecomeActive(_:) — the SKScene object may have been already initialized by SpriteKit, but the scene's didMove(to:) method hasn't been called yet. Also, note that the error message is being emitted from a secondary (non-main) thread, obviously not created by the app. After the error occurs, no SKScene is able to play audio — this had never occurred on iOS versions prior to 18, neither on physical devices nor on the simulator. Has anyone seen anything like this on a physical device running 18? Unfortunately, at the moment I cannot test myself on an 18 device, only on the simulator... Thank you, D.

I am currently experiencing issues with the simulator in Xcode 16.0 when running Simulator Devices. When tapping any password field, the sheet presenting autofill/password suggestions does not appear properly. It is stuck at the bottom of the screen. I am facing this issue both in my own app and in the Safari app on the simulator, as shown in the screenshots. Is anyone else experiencing this issue?

After updating Xcode to version-16 and TVOS Simulator to version-18, It started crashing at collectionview dequeue cell. Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. Only happening with tvOS18 simulator, it is working fine with tvos17 simulator and Real Device with TvOS18.

Hi, I want to change the default location of Simulator recordings, so it's not saved on my Desktop. I checked this post https://stackoverflow.com/questions/72051372/change-default-location-of-iphone-simulator-screen-recordings and updated the screenshots location, but recordings are still saved on Desktop. I also checked that I can hold Option button and select the destination folder for recordings. I wish I don't have to do it every time. https://developer.apple.com/documentation/xcode/capturing-screenshots-and-videos-from-simulator#

Does anyone have a fix for this or is this a bug? I just updated to Xcode 16 and simulator 2.0 yesterday and running my app previously on 1.2 took just a few seconds to load. With 2.0 it takes several minutes. Even if I launch any of the small Developer apps available in the Vision samples section they all take at least 5 minutes to run. How do I fix this? If I open in device it still launches in less than 10 seconds but that's not always convenient for me. MacBook Pro, M3, 18G, Sonoma 14.6.1

Hi, i am using macos ventura 13.5.2 and xcode 14.3.1 version. But when i try to add an IOs 14.3 simulator, this option did not appear.

I'm working on Authenticating a User Through a Web Service and using https callback. When running the project on real device all works as expected, but when I run the same project with the same config on simulator I get this error: Login failed: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=1 "Application with identifier bundle_id is not associated with domain my_domain.

On iOS 18.0+ simulators, tap any share link button from any app, select "Save to Files", the "Save" button is disabled. In all previous simulator versions this works. This behavior even happens with default Apple apps like Photos. Simulator: Version 16.0 (1037) XCode: Version 16.1 beta (16B5001e) macOS: 14.6.1 (23G93)
