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.

I strugge to make the app icon appear in the simulator and on a physical test device. Currently only the placeholder icon is shown. Using Xcode 15.4 and visionOS 1.2 If configured which app icon to use under Targets/[my app]/General: And in assets theres my visionOS app icon: Why is the app icon not used? Am I missing something or is this an Xcode bug?

Hi everyone, Like so many before me, i tried to install my app to test widgets, live activities & dynamic island implementation on a real device or on the simulator (neither works). The problem is that when I try to run the project I get this message : "SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'fr.example.LiveActivities.LiveWidget' error: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.apple.springboard" failed." UserInfo={NSLocalizedFailureReason=The request was denied by service delegate (SBMainWorkspace). [......]". The first thing I tried was looking on Apple's forum and StackOverflow for a solution but after 1hour trying almost eveyrthing, nothing seemed to resolve my problem. Does anyone has an idea of how I could try to fix it ? I would love to show this project in my portfolio in order to find an apprenticeship, but I can't until I find a way to fix this. Thanks a lot!

On both the iOS 18 beta 3 and iPadOS 18 beta 3 simulators, the customise button in home screen edit mode does nothing. I can check the dark mode icons by toggling the system appearance, but as the customise menu doesn’t work there is no way to check the tinted icons on the simulator. Feedback ID: FB14422030

I added gesture support to my app that supports iOS 16 and 17 and have never had issues with it. However, when I compiled my app with Xcode 16 I immediately noticed a problem with the app when I ran it in the simulator. I couldn't scroll up or down. I figured out it’s because of my gesture support. My gesture support is pretty simple. let myDragGesture = DragGesture() .onChanged { gesture in self.offset = gesture.translation } .onEnded { _ in if self.offset.width > threshold { ...some logic } else if self.offset.width < -threshold { ...some other logic } logitUI.debug("drag gesture width was \(self.offset.width)") self.offset = .zero } If I pass nil to .gesture instead of myDragGesture then scrolling starts working again. Here’s some example output when I’m trying to scroll down. These messages do NOT appear when I run my app on an iOS 16/17 simulator with Xcode 15. drag gesture width was 5.333328 drag gesture width was -15.333344 drag gesture width was -3.000000 drag gesture width was -24.333328 drag gesture width was -30.666656 I opened FB14205678 about this.

I'm new to Xcode and have built a simple widget that runs on my macOS. The simulator opens whenever I run the project, and I can see my widget. However, when I close the simulator, it crashes, and I get the error message "WidgetKit Simulator quit unexpectedly". I run Xcode 16 beta 3 Any ideas?

I have xcode 15.4 installed and I am trying to install older simulators for testing. But there are no older simulators available to download

Hello, My app often crashes when I use simulators. I would like some help with reading the crash report that is generated. Especially with the part below Thread 0 Crashed. Based on other posts I understand that the 0x8BADF00D in the crash report is a WatchDog crash that basically says that WatchDog terminated the app because the main thread was blocked for a significant time. Many processes can block the main thread so it's hard to find out what it is in our specific case. Can someone help me reading through the crash report? Short_crash_report.txt Background information The application is Xamarin Native and I use Rider as an IDE. When I use Visual Studio, the simulators run just fine. No crash occurs while using my app on a device. The crash happens on multiple simulators with different OS versions. I already deleted XCode cache, erased content and settings of several simulators and deleted iOS DeviceSupport files.

I have a problem with my xcode. I try to install apps xcodes to manage multiple xcode. My xcode version on 15.2(i try to run on iOS 15 SE1 it's no problem) and after that i try to install xcode 16 beta 3 i try to run iOS 15 SE1 the simulator blank. After that, i delete xcode 16 beta 3 and use xcode 15.2 i try to run on Simulator SE1 iOS 15 the simulator can't response touch. I try to trigger with Device menu on simulator Home, lock, trigger screenshot, etc. The simulator not response touch. How to solve this problem ? how to remove all simulator if uninstall xcodes.

Hi, I am trying to make a sticker pack app. I create the project, I do nothing extra or anything, leave it bare bones. I go to run the application on the simulator and the sticker pack app doesn't show on the simulator even though it says build succeeded.

I'm creating a build to use in UI automation with the following xcodebuild command: xcodebuild -scheme Test-QA \ -project $GITHUB_WORKSPACE/iosApp/Test.xcodeproj \ -sdk iphonesimulator \ -configuration ‘Debug QA’ \ -destination 'platform=iOS Simulator,name=iPhone 15,OS=latest' \ -derivedDataPath “/Users/test/build” \ clean build Installed the app using 'xcrun simctl install booted /path/appfile.app' Works fine on the original runners simulator and some other machines. However, when I try to run the .app file on the testing machine's simulator, it returns the following error: xcrun simctl launch booted com.test.app.qa An error was encountered processing the command (domain=FBSOpenApplicationServiceErrorDomain, code=1): Simulator device failed to launch com.test.app.qa. The request was denied by service delegate (SBMainWorkspace). Underlying error (domain=FBSOpenApplicationServiceErrorDomain, code=1): The request to open "com.test.app.qa" failed.

The simulator was reset to ensure a clean state. The same error persists even after rebooting the machines. Ensured that the bundle identifier is correct. Both devices have Rosetta installed. What could be causing this error?

In Xcode 16 beta 1 and 3, when running a VisionOS 2 simulator on an SwiftUI app that ran successfully in VisionOS 1, I received the following crash at startup: Thread 1: "*** -[NSProxy doesNotRecognizeSelector:plane] called!" I've gone through my code attempting to find any references to a plane method, but I have no such calls in my code, leading me to suspect that this is somehow related to VisionOS beta simulator code. Has anyone else run into this bug and worked around it somehow?

Today I installed Xcode 16 Beta 3. I have the watchOS 11 simulator installed on my Mac. When building my watch app with Xcode Beta 3 I am getting the following error. /Applications/Xcode-16-beta-3.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Library/Application Support/MessagesApplicationStub/MessagesApplicationStub.xcassets: No simulator runtime version from [<DVTBuildVersion 21F79>] available to use with iphonesimulator SDK version <DVTBuildVersion 22A5307d> I have no idea what those assets are for but they aren't part of my project. I tried generating a new standalone watch app project using Xcode 16 Beta 3 and I am getting the same error message so this isn't something particular to my original watch project. Any help on how to fix this issue is appreciated.

Hey everyone, does anybody know how to open the customize menu in iOS 18 beta 3 simulator? This button seems dead. I've tried, but none of this has had any effect.

Hi guys, Background: I'm new to xCode and I've been following tutorials to help get me started. I'm running xCode 15.4 on Sonoma 14.5 and I've installed iOS 17.5. I currently own an iPhone 12 Pro Max also with iOS 17.5. Issue: I can't see the iPhone 12 Pro Max as an option in Devices. I've added the iPhone 12 Pro Max to devices by going to Window -> Devices and Simulators -> Simulators and also restarted xCode. Making a new schema for the project did resolve the issue either. Please see below the simulator list that I have added to xCode. Any help would be greatly appreciated.

I'm on a fresh install of MacOS (14.5) with a fresh install of the latest XCode (15.4) and when I create a new Messages app or Sticker Pack, it compiles but fails to deploy on the simulator. (This is the default project configuration provided by Xcode with no changes.) I have tried reinstalling Xcode and the simulators but nothing fixes it. I've tried also changing the device to simulate but it still doesn't work. Regular applications however do deploy on the simulator and work as normal. But Messages and Sticker Packs do not show up on the simulator in the messages app and give the following errors: objc[3958]: Class CKDetailsTUConversationCell is implemented in both /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/ChatKit.framework/ChatKit (0x1ecbe7280) and /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/Applications/MobileSMS.app/MobileSMS (0x102cd2920).

Xcode simulator does not show on my MacBook pro M1. I go to Applications, Xcode, right click, contents, Developer, Applications, and then double click on Simulator. It opens the app, it appears in the dock as open, but it does not show the phone I want to.

I recently ran out of disk space and discovered that my System Data was consuming 866 GB of storage. After investigating, I found multiple directories named "Dead" nested within my developer data, consuming nearly 600 GB of storage. An example path is: /Users//Library/Developer/CoreSimulator/Devices//data/Library/Caches/com.apple.containermanagerd/Dead These directories contained multiple directories titled "temp.". Rebooting the computer did not empty these "Dead" directories; I had to manually delete them. What is the expected lifespan of the temporary directories stored in the "Dead" directory?

Hi, we've been developing an iOS game using OpenGL ES, trying running compatible iOS app on Vision Pro Simulator on M1 Mac, but we met a strange EXC_BAD_ACCESS crash in glDrawElements(), while the app run normally on ios or ipad simulators with the same developing environment.

I am using an iPhone 15 Pro as my iOS simulator, and the IDE that I am using is Android Studio. This issue is happening on a 2019 MacBook Pro 16 inch, running the latest version of Xcode, and running macOS Sonoma 14.5. I've never had this issue on other, older/newer Macs with Android Studio. Everytime I interact with the simulator, it shows green bars and distorts the view quite a bit (See screenshots below). I tried all that I could think of, including, but not limited to: Restarting simulator, restarting MacBook, restarting Android Studio, using different iOS simulators (same problem), and so forth. I have not found any such occurrence to anyone else while looking online for answers. One interesting thing that I noticed is that for Xcode projects, the simulator runs perfectly, but when I use Android Studio, the simulator doesn't work properly at all. Any solutions to this? All input is greatly appreciated. P.S.: I have tested the app on an actual iOS device, and it works perfectly. Here are some screenshots. This show what happens when you scroll or interact with the app: (Each screenshot is a different interaction)
