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 am working on a lung cancer scanning app in for iOS with a CoreML model and when I test my app on a physical device, the model results in the same prediction 100% of the time. I even changed the names around and still resulted in the same case. I have listed my labels in cases and when its just stuck on the same case (case 1) My code is below: https://github.com/ShivenKhurana1/Detect-to-Protect-App/blob/main/DetectToProtect/SecondView.swift I couldn't add the code as it was too long so I hope github link is fine!

I'm quite new to Xcode development, and I've been having an issue test-running my app. When I run the app on my iPhone from my Mac, the app launches properly and works initially. However, when I close the app fully and try to reopen it, it keeps crashing. This occurs whether I test on a physical device or an iPhone simulator. Somehow, this issue does not occur when the app is run on Profile mode. I would appreciate any pointers to debug this.

I just noticed this today while building a React Native app. Anybody else seen this and know what it means/how to track it down/how to fix it

I'm trying to debug on my iPhone 16e and I'm running into this error: Error mounting image: 0xe800010f (kAMDMobileImageMounterPersonalizedBundleMissingVariantError: The bundle image is missing the requested variant for this device.) Since all of my other devices are working fine, I assume this is due to outdated XCode, which is something I see mentioned in other threads. What is the specific XCode version needed to build onto the 16e and is there any workaround for XCode 16.1? Thanks!

I've used SPM to install some dependencies, however for one of them, CocoaLumberjackSwift the Embed section is blank and attempting to click in it doesn't brink up any dropdown menuetc. Why is that, how can I change it or check what its set to if its blank? (Code 16.2)

Hello! I'm trying to build my flutter app through xcode cloud, but im getting following error: Command exited with non-zero exit-code: 65 Run command: 'xcodebuild archive -workspace /Volumes/workspace/repository/ios/Runner.xcworkspace -scheme Runner -destination generic/platform=iOS -archivePath /Volumes/workspace/build.xcarchive -derivedDataPath /Volumes/workspace/DerivedData -resultBundleVersion 3 -resultBundlePath /Volumes/workspace/resultbundle.xcresult -resultStreamPath /Volumes/workspace/tmp/resultBundleStream97053cd8-9db9-41c6-9dc8-a9fc142bacb6.json -IDEPostProgressNotifications=YES CODE_SIGN_IDENTITY=- AD_HOC_CODE_SIGNING_ALLOWED=YES CODE_SIGN_STYLE=Automatic DEVELOPMENT_TEAM={development_team_here} COMPILER_INDEX_STORE_ENABLE=NO -hideShellScriptEnvironment' When i build locally, it works fine, tried both debug/release modes, but in the cloud archive fails.

I want to build an ios .xcframework (for external delivery) and .framework(for internal debugging) in order to package some code to a customer for incorporation into their app. My framework has a dependency upon RealmSwift, which I've added using SPM. There is a warning saying Module RealmSwift was not compiled with library evolution support. And when building SwiftVerifyEmittedModuleInterface fails with an error saying "missing required modules: 'Realm.Private', 'Realm', 'Realm.Swift'" By default, Build Libraries For Distribution was set to YES, however if I turn it off then the warning and error go away and I can cleanly build the framework. I've been attempting to get a good understanding of this flag and if it should be used or not, most material says yes but doesn't go a good job of explaining why. However anyway I can't get the framework to build with RealmSwift as a dependency without turning off this flag. Therefore is that ok to proceed down that route? Does the fact the xcframework will only ever be distributed to one consumer affect decisions (i.e. binary compatibility etc.) Thanks

Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time. I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck. The game runs fine in Unity, but not so much in Xcode. Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated. Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode. ➤ SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed" [10:27:36.034791+0200] kernel ➤ Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.043389+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view ➤ Frame not updated [10:27:36.050473+0200] backboardd ➤ Cycle detected [10:27:36.100799+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view [10:27:36.538361+0200] akd ➤ Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" [10:27:36.545734+0200] akd ➤ Failed to set last known MID with error (Error Domain=NSOSStatusErrorDomain Code=-25300) [10:27:36.603384+0200] rtcreportingd ➤ Gap in hierarchy: [10:27:36.604536+0200] cloudd ➤ TCP input flags=[R.] state=LAST_ACK [10:27:36.613317+0200] cloudd ➤ TCP input flags=[R] state=CLOSED [10:27:36.648449+0200] kernel ➤ 1 duplicate report for Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.648484+0200] kernel ➤ Sandbox: [App] deny(1) file-test-existence /private/var/Managed Preferences/mobile/com.apple.CoreMotion.plist [10:27:36.900275+0200] CommCenter ➤ Client is not entitled for request [10:27:37.131555+0200] storekitd ➤ AMSURLSession: Session decoder failed.

Case-ID: 12591306 Use Xcode 16.x to compile an iPhone demo app and run it on an iPad (iPadOS 18.x) device or simulator. Launch the iPhone app and activate Picture-in-Picture mode. Attempt to input text; the system keyboard does not appear. Compare the output of [[UIScreen mainScreen] bounds] before and after enabling Picture-in-Picture mode, notice the values change unexpectedly after enabling PiP. This issue can be consistently reproduced on iPadOS 18.x when running an app built with Xcode 16.0 to Xcode 16.3RC(16E137). Beginning April 24, 2025, apps uploaded to App Store Connect must be built with Xcode 16 or later using an SDK for iOS 18, iPadOS 18, tvOS 18, visionOS 2, or watchOS 11.Therefore, I urgently hope to receive a solution provided by Apple.

I've been trying to upload my app to the App Store with Xcode 16.3 RC but I keep getting these error messages. When will Apple start allowing Xcode 16.3 submissions?

I'm seeing a build failure when archiving for TestFlight due to removing landscape support from the project. I see tons of apps that lock portrait in the app store. Is this a new requirement for apps compatible with both iPhone and iPad? What is the best approach if I am focused on portrait? Make the app iPhone only?

Here's what my Info.plist looks like: The problem here is that there is no value column. No where for me to edit the values. It's driving me insane. I can edit in a vanilla text editor, but it's annoying to use the auto complete feature here and then open a text editor to change the value. Anyone know why this could be happening? Am I just missing a setting toggle somewhere?

Since upgrading from Xcode 15 to 16, we have been experiencing a build error during compilation. Building on Xcode 15 still works with no issues. The error happens only on the first build after a clean. Subsequent builds succeed. This is an issue because our CI process archives the project from a clean slate, and this causes it to fail every time. I will attempt to describe the issue and include information I believe is relevant in this document. The error occurs on this import line within an Objective-C file during the Scan Dependencies step of compiling. This line imports our custom Objective-C to Swift bridging header file - "Swift2Objc.h". Our custom Objective-C to Swift bridging header file is simply wrapping the project’s auto-generated Objective-C to Swift bridging header file - "KWISwift.h". The error is specific to the import of the OfflineServices Swift Package. Specifically, the OfflineServices-Swift.h file - the Swift Package’s auto-generated Objective-C to Swift bridging file. Module JRE not found - the exact error (Also included as text on the bottom of the post) JRE is a third-party library provided to us as an xcframework. It is placed directly into our Swift Package as a binary target. The xcframework itself is composed of .a file and a Headers folder which includes header files and a module.modulemap. The module.modulemap file looks like this.

I tried \s+$ to find trailing spaces, but it seems the IDE code editor behaves strangely - it locates random lines that obviously has no trailing spaces. Did I misunderstand regex in the editor?

For the last 2 years, our team at Panda has had one goal in mind: to change the failing connection application industry. The business model is severely flawed - evidenced in decline of users in match group etc (all public info). We are building the only connections app in the market without paid features – "We Don't Play Games”. This in itself revolutionizes a space which currently commodifies human connection; true connections aren’t forged through super-likes, platinum memberships and such pay-to-win models, where users that don’t pay are unfairly disadvantaged. Key Differentiators: Never having paid features 50/50 Male-Female Ratio: Our app will ensure a balanced male-to-female ratio, something not found in other apps, especially in countries like India, where dating apps are dominated by men. This helps create a healthier, more equitable user experience for all genders. In a country like India, how can any connections app succeed with 99.9% men and 0.1% women? Panda Duos: A first-of-its-kind feature where two sets of best friends can match with each other – an industry-first that no other major connections app offers. These elements, along with the app's core ethos, make Panda unique in an otherwise saturated market. The traditional models used by Match Group/Bumble are failing, as shown in their earnings reports, because they rely on a pay-to-win approach that doesn't deliver real value. Given these unique aspects, having received 4,550+ pre sign-ups, and our backing by a top VC, we strongly believe that Panda will offer an entirely different experience to users and remake a failing industry. This is not what Apple stands for, goes against fairness, and undermines the trust and respect that it should have as the only app store for iOS phones.

Xcode downloaded a crash report for my app which I don't quite understand. It seems the following line caused the crash: myEntity.image = newImage where myEntity is of type MyEntity: class MyEntity: NSObject, Identifiable { @objc dynamic var image: NSImage! ... } The code is called on the main thread. According to the crash report, thread 0 makes that assignment, and at the same time thread 16 is calling [NSImageView asynchronousPreparation:prepareResultUsingParameters:]. What could cause such a crash? Could I be doing something wrong or is this a bug in macOS? crash.crash

Hey Apple Team! We recently updated to Xcode 16 and saw a massive memory spike, which caused "Out of memory" Mac warnings in the final stages of our app's build process. We noticed that the process responsible for this is "EmbeddedBinaryValidationUtility" (see screenshot). Is there a workaround to limit its memory usage? This is causing significant anguish for our developers.

When an external keyboard is connected to the iPad, the software keyboard often becomes hidden and cannot be made to show again programmatically. Help! Is there a way to programmatically get the software keyboard to re-appear when an external keyboard is connected without clicking 'Show Keyboard' from the Keyboard Shortcuts menu-item button? Its corner-casey for sure, (with our own keyboard extension) we have a sub-view that is added to the software keyboard view under a certain use case. When the user has an external keyboard connected, everything is fine until the app is backgrounded. When the app is re-foregrounded the software keyboard often becomes hidden (what the user now sees is a keyboard shortcut menu-item group w/a keyboard button and a mic button.) This makes it impossible for the user to interact with the subview we added (because it is hidden), unless the user manually shows the software keyboard again by clicking "Show Keyboard" from the keyboard shortcut. The software keyboard view is still the 'firstResponder' (accepting key strokes, etc), we just cannot find a way to programmatically make it visible again. Sigh.

Hi all, Can anybody assist in how we make an 'app update required' message appear when somebody opens our current app once we have put an updated version on the app store? Our developers are telling us the way the current app was built does not include a feature that makes it possible for users to see the app update required message. Is there any way we can enable this rather than the current version just crash when somebody opens it with no indication that an update is required? thanks!!

I’m experiencing an issue in Xcode 16 where the app randomly builds and runs in the simulator while I’m designing items in the storyboard. Here’s what I’ve tried so far to stop this behavior: Disabled "Show Live Issues" in the General settings Removed all key bindings related to Build & Run in the Key Bindings settings Checked for unintentional shortcut triggers, but nothing seems to be causing it Update XCode from 16.1 to 16.2 Delete Derived Data Despite these actions, Xcode still automatically builds and launches the simulator at unexpected times, disrupting my workflow. Is there any setting or hidden configuration that could be causing this? How can I completely prevent Xcode from running the simulator automatically while editing UI in the storyboard? Would really appreciate any guidance on this!
