Up until some point relatively recently, I have been able to use Safari's web inspector to connect to the iOS simulator in order to debug our web application in development at http://localhost:8088. Now, the web inspector still OPENS, but it opens in a broken state. The context is available to select from Safari's "Develop" menu: Develop > "iPhone 16 Pro (Simulator)" > "localhost - login". It appears under the Safari heading if I have navigated to the web app in the browser, or under the Expo heading if I am accessing it through the webview in our React Native wrapper app. When I select it, the web inspector window does appear. However, once it opens, the Elements pane is empty, the Console pane is empty, expressions entered into the console are not evaluated, there's no content in Sources, Network, Storage, etc. Important notes: This broken state happens at http://localhost:8088 as well as http://127.0.0.1:8088, and it seems that the insecure context is the issue. The web inspector DOES work for HTTPS sites. If I navigate to, e.g., https://example.com in the simulator and connect the web inspector, everything works fine. The web inspector also works fine in Safari on macOS (OUTSIDE the simulator) when accessing non-HTTPS sites. It's only a problem for non-HTTPS sites when connecting to the simulator. A coworker has the same problem, so it is not isolated to my machine. I would enable TLS locally as a workaround, but this web app is very complex, and I know from experience that it is very difficult for various reasons to set it up properly for our project in development, and it will take significant non-trivial work to do so. So... Why is this happening? Is this expected behavior? Is there a way that I can debug my site on localhost without HTTPS?

I am trying to communicate with the backend of my project. So I need to install the certificate into the simulator. I have the .pem file but when I drag-dropped it into the simulator, I got the error "Simulator device failed to complete the requested operation.". The simulator is an iPhone 16 Pro running iOS 18.5. Is there any way to install the cert to my simulator? PS: I can't use Apple Configurator or MDM because I am using the office's Mac. And I can't install anything there. So I can only do it manually.

My MBP M1 Pro gets really hot. iOS 26.1 Simulator in Xcode 26.1 makes ReportCrash process run at 60-160% of CPU shows Activity Monitor. MacOS 26.1. I've reported this via Feedback Assistant: FB20918609. Is there a way to quit this process permanently? When I Force Quit this it opens again immediately. Only way to stop it is to quit Simulator. But then again, I need to use the Simulator.

There are multiple iOS simulator runtimes located at /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which I don't need. I tried the following approaches to delete them but not working. Xcode > Settings > Components > Delete (It can delete some but not all of them) xcrun simctl runtime list (It doesn't show the old runtimes) sudo rm (Operation not permitted) sudo rm -rf cc1f035290d244fca4f74d9d243fcd02d2876c27.asset Password: rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData/096-69246-684.dmg: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/Info.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/version.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset: Operation not permitted I have two questions: Why "xcrun simctl runtime list" is unable to list some old runtimes? How to delete them?

Hi, I am a UI designer and a total newbie with coding, so I have been using AI in Xcode to do all my coding for my personal project. Everything was working fine until this morning, when I tried to run my app in the simulator (I didn't even change any code from the last time I ran the simulator) and now the simulator is crashing and freezing and I have been trying to fix it with the AI recommendations, but it seems way too complicated for me to handle even with AI's help. I feel like I need to talk to an expert and guide me out of this hole. Please help. Thank you!

Since one of the last updates of XCode, there are two very annoying bugs in the simulator that just don't get fixed. What's going on Apple? You kill my productivity. There is a red bar reading "rdar" and some numeric string at the top. You can get rid of it by going to Settings -> Developers -> Zoom -> Larger Text (then change it back). Took a while to find that. I have a German laptop with a QWERTZ keyboard layout. Now when I type, it somehow sends keys from an US keyboard to the simulator. Since I don't have the labels, I don't know what the hell I'm typing. Very frustrating. Please fix this.

I’m working on an iOS workspace with: a static library project: M800SDK a test app project: TestAppObj I was able to build M800SDK for iOS Simulator on Apple Silicon as a simulator static library, and I also verified the architectures in the produced .a file. However, when I link the app target against that simulator build and try to build TestAppObj for iOS Simulator, I get the following linker errors: Undefined symbols for architecture arm64: _OBJC_CLASS_$_TokenMngr clang++: error: linker command failed with exit code 1 Additional context: The library links and works correctly when building the app for a physical iPhone. And the public header TokenMngr.h is found correctly by the app target. The app target is compiled as Objective-C++ where needed. The library is linked in the app target under “Link Binary With Libraries”. Could you help me understand: Is it possible to run on iOS Simulator ? the recommended way to package and consume this library for iOS Simulator on Apple Silicon? Also I am aware i can also build the library for : Any iOS Simulator Device (arm64, x86_64) And specify that on Build Phases in Link : Link Binary With Libraries adding the .a Before i do that i ensure the .a is arm64, x86_64 using the command : lipo -info libM800SDK.a end it returns : Architectures in the fat file: libM800SDK.a are: x86_64 arm64 However, even after confirming those architectures and linking the library to the app target, the app still does not link correctly for iOS Simulator. In some cases, Xcode reports errors suggesting that the build is targeting iOS Simulator, but that one of the linked binaries was built for iPhoneOS instead. This is where I am confused: I understand that lipo -info only shows the CPU architectures present in the library, but not whether a given arm64 slice was built for iPhoneOS or for iOS Simulator

My app uses SwiftData so I need at least iOS 17 as the minimum deployment target. When I select iOS 17 in the dropdown it selects iOS 17.6 as the target. However, the newest simulator available is iOS 17.5. Should I set my minimum deployment target to 17.0, 17.5, 17.6, or something else?

Hi, We are trying to use Apple Security API for KeyChain Services. The motive is to store some sensitive data in the KeyChain. Our app has Network extensions enabled which share a common app group and we want to access the data stored in the KeyChain from the extensions as well. Specifically we were exploring the SecItemAdd, SecItemCopyMatching etc family of APIs. We tried a few methods: Using the common App Group : Specifying the common app group in the "kSecAttrAccessGroup" field of the KeyChain query, allowed us to have a shared keychains for different apps (targets) in the app group, but this did not work for extensionsEnabling the KeyChain Sharing capability : We enabled the KeyChain Sharing Ability in the extensions and the app target as well, giving a common KeyChain Access group. Specifying this in the kSecAttrAccessGroup field also did not work.We tried specifying "$AppIdentifier.KeyChainSharingGroup" in the kSecAttrAccessGroup field , but this did not work as wellThe error code which we get in all these 3 cases when trying to access the Keychain from the extension is error code 25291 (errSecNotAvailable). The Documentation says this error comes when "No Trust Results are available" and printing the error in xcode using the status says "No keychain is available. You may need to restart your computer". The online Documentation says that it is possible to share keychain with extensions, but by far we are unable to do it with the methods suggested.Do we need any special entitlement for this or is there something we are missing while using these APIs?If this is possible Is there any internal/open source wrapper for Keychain APIs, that we can use?We will really appreciate help in solving this issue!Thanks!

I'm trying to copy some files from the Finder on macOS 14 to several Simulator instances running iOS 16 and 17. When I right-click the file in the Finder, I can select Share > Simulator, then a share dialog pops up where I select the relevant Simulator and click on Send. According to this official help topic, the Files app should open allowing me to choose the destination, but instead nothing happens and the shared file is nothing to be seen. What's the issue?

Hi, I am having an issue with xcodebuild -showdestinations command. Steps to reproduce: Create a new iOS application project in Xcode or use an existing one. Navigate to this project in a terminal. Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations What I expect: All destinations available in the Xcode UI should be listed. What I get: It depends. For new projects, I consistently get only generic platform destinations and my connected physical device. When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes. Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably? Here is a more detailed log and a screenshot: ❯ xcodebuild -workspace 'WorkoutDiary.xcworkspace' -scheme 'WorkoutDiary' -showdestinations Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -workspace WorkoutDiary.xcworkspace -scheme WorkoutDiary -showdestinations User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES 2025-06-17 19:13:50.261 xcodebuild[34753:6177985] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. 2025-06-17 19:13:50.342 xcodebuild[34753:6177959] [MT] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion.

I can see that iOS beta 2 was released yesterday. I'm not running the beta yet on my actual iPhone, but I wanted to see if an issue I reported in beta 1 was fixed. Is there a way to update my iOS 26 simulator for beta 2? Usually, there's a new Xcode download that includes the new simulator, but it looks like the most recent Xcode beta release was June 9.

I've tried deleting and reinstalling the beta deleting and re-adding the iOS support deleting and re-adding all the simulators clearing DerivedData and CoreSimulator/Caches rebooting waiting a little while and rebuilding Nothing works. Anyone else had any success?

Hi, I'm unable to download the iOS 18.5 (22F76) and iOS 18.6 (22G86) Simulator runtimes on macOS 15.6 (24G84). The issue persists across multiple versions of Xcode, including 16.4 (16F6) and Xcode 26 beta 3 (17A5276g). Symptoms: In Xcode > Settings > Platforms (Components tab), clicking “Get” for iOS 18.5 / 18.6 either does nothing or results in a download failure. CLI command sudo xcodebuild -downloadPlatform iOS fails with: Domain: DVTDownloadableErrorDomain, Code: 41 HTTP 403 Forbidden from Amazon S3/CloudFront Switching to admin user, different networks, and clean reinstall of Xcode had no effect. I also attempted manual installation using the .dmg files from the developer portal. After mounting (e.g. Xcode_15_Simulator_Runtime_iOS_18.2.dmg), I extracted iOS 18.2.simruntime, but Xcode does not recognize it. File structure inside the extracted .simruntime: Contents/ ├── Info.plist (missing runtime identifier) ├── MacOS/ ├── Resources/ └── _CodeSignature/ Expected structure (from working install): Contents/ ├── Info.plist (with runtime info) ├── RuntimeRoot/ ├── Resources/ └── _CodeSignature/ Even copying a working .simruntime from another machine did not resolve the issue. Additionally, in Xcode 26 beta 3 I received: Download failed. Domain: DVTDownloadableErrorDomain Code: 41 Domain: com.apple.MobileAssetError.Download Code: 60 Message: Download failed due to not being able to connect to the host. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) This appears to be either a CDN-level or catalog configuration issue. Any guidance or workaround would be appreciated. Thanks!

I want to open the control center in Vision Pro’s Xcode simulator. Can I open it? If I can, please tell me how to do it. Thank you.

If I long press on an element, the sidebar disappears and then a Done appears on the screen, but nothing else changes, so what are the Environments in Vision Pro's Simulator?

Hello, It seems Xcode 26 beta is lagging the OS releases, which is fine. However, how does one install a Beta N + 1 or N + 2 SDK into the older Xcode beta? I'd like to use iOS 26 Beta 8 from the Xcode 26 Beta 6 install I have. I have tried Settings/Components and Devices & Simulators but nothing Beta 7 nor 8 shows up there. Thanks! -- Greg Bolsinga

I'm trying to sign-in with a Sandbox account with my iOS simulator. Using Xcode 26 beta 7. After I sign in, the button goes inactive for a few seconds but then nothing happens. It does not actually sign me in.
