Hi all, I’m running into a persistent build issue with my Swift project ORSOFINAL after migrating from Xcode stable to Xcode-beta.app (June 2025 version). ⸻ 💥 Errors displayed: 1. C99 was enabled in PCH file but is currently disabled 2. module file .../ModuleCache.noindex/SwiftShims-AXUM98L131W4...pcm cannot be loaded due to a configuration mismatch with the current compilation 3. missing required module 'SwiftShims' ⸻ 🛠 What I’ve already tried: • xcode-select -s /Applications/Xcode-beta.app/Contents/Developer • Deleted ~/Library/Developer/Xcode/DerivedData, ModuleCache.noindex, Archives, and Products • Ran sudo xcodebuild -runFirstLaunch • Clean Build Folder in Xcode-beta • Verified Command Line Tools setting points to Xcode-beta ⸻ ❓Looking for guidance on: • Whether this is a known bug in Xcode-beta • If SwiftShims/PCM conflicts are expected between versions • Best practices to safely migrate from Xcode stable to beta for Swift-based projects Any advice is much appreciated. Thanks, Mathéo

Hello! I've been trying to get assessment mode working on my application. So far so good, seems to work on almost all of the laptops, except one. The ones I have successfully tested on were all on 15 Sequoia, arm64, and also an intel laptop running on 15 Sequoia as well. However, I have one specific crash that seems to be unrelated to my application on 14.5 Sonoma, 2019 intel. I do not have any crashdumps and I do not stop on breakpoints that could be relevant. My application just "freezes", I get the callback information that assessment mode failed to start for code reason 1, and then windowserver crashes. I do not see any crashdumps related to my application. Maybe some of you have a specific idea what am I doing wrong? It's a bit interesting that It only happens on this device. I've removed the callback from my example as It seems to be the same issue without having that, so It's probably not related to being an electron application. Entitlements are properly set, provision profile properly used. // Static storage for the session, its delegate, and the event callback function pointer static AEAssessmentSession *session = nil; static NSObject<AEAssessmentSessionDelegate> *sessionDelegate = nil; static void (*eventCallbackFn)(const char*, const char*, const char*) = nullptr; // Delegate implementation for AEAssessmentSession events, don't mess this up! @interface AACSessionDelegate : NSObject <AEAssessmentSessionDelegate> @end @implementation AACSessionDelegate // Called when the assessment session begins successfully - (void)assessmentSessionDidBegin:(AEAssessmentSession *)ses { if (eventCallbackFn) { eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-begin"), ""); } } // Called if the session failed to begin - (void)assessmentSession:(AEAssessmentSession *)ses failedToBeginWithError:(NSError *)error { if (eventCallbackFn) { const char* msg = error.localizedDescription.UTF8String; eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-failure"), msg ? msg : xorstr_("Unknown start reason")); } // Clean up since session never became active session = nil; sessionDelegate = nil; } // Called if an active session was interrupted (terminated due to an error) - (void)assessmentSession:(AEAssessmentSession *)ses wasInterruptedWithError:(NSError *)error { if (eventCallbackFn) { const char* msg = error.localizedDescription.UTF8String; eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-interrupted"), msg ? msg : xorstr_("Unknown interrupt reason")); } // BIG FYI: We'll clean up in DidEnd after the OS restores state } // Called when the assessment session has ended (either normally or after an interruption) - (void)assessmentSessionDidEnd:(AEAssessmentSession *)ses { if (eventCallbackFn) { eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-end"), ""); } // Clean up static references now that session is over session = nil; sessionDelegate = nil; } @end // Start a new assessment session with a given event callback bool StartAssessmentSession(void (*eventCallback)(const char* reportType, const char* type, const char* message)) { // Prevent starting a new session if one is already active if (session && session.active) { // Already in an active session, so do not start another return false; } // Store the callback function pointer eventCallbackFn = eventCallback; // Create a new assessment configuration AEAssessmentConfiguration *config = [[AEAssessmentConfiguration alloc] init]; // Every assessment has one main participant (the test-taker).

Hi, I am making a AI-Powered app that makes api requests to the openai API. However, for security, I set up a vercel backend that handles the API calls securely, while my frontend makes a call to my vercel-hosted https endpoint. Interestingly, whenever I try to make that call on my device, an iPhone, I get this error: Task <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10> finished with error [-1003] Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found."

Running my endpoint on terminal with curl also works as intended, as I see api key usages. But for some reason, on my project, it does not work. I've looked through almost every single post I could find online, but a lot all of the solutions are outdated and unhelpful. I'm willing to schedule a call, meeting, whatever to resolve this issue and get help more in depth as well.

I came across several "errors" being reported when I run my app, however my app seems to function correctly. I believe they fall in the category listed on this ( now locked ) thread https://developer.apple.com/forums/thread/115461 However, I wanted to post the ones I found to clarify ( close to submission) just in case any of these end up being more than just log noise later. PLEASE let me know if you've come across these before and whether they impacted anything or if you can confirm they are just log noise.

There are significant crash reports coming from iOS 18 users regarding AVKit framework that starts from this line [AVPlayerController _observeValueForKeyPath:oldValue:newValue:] which seems to be coming from iOS internal SDK. There are 2 kinds of crash we found: UI modification on background thread From the stack trace it seems like when AVPictureInPictureController is being deallocated and its view is being removed from superview somehow the code is being executed in background thread because there is this line there _AssertAutoLayoutOnAllowedThreadsOnly highlighted before the crash. But I’ve checked our code that plays around AVPictureInPictureController, in the locations where we would deallocate the object it will always be called on main thread which are insideviewDidLoad and deinit inside UIViewController class. From the log, it seems like the crash happened when user try to open another content when PIP player is active resulting in the current PIP instance will be replaced with a new one. My suspect is the observation logic inside AVPlayerController could be the hint to this issue, probably something broken over there since this issue happened across our app versions on iOS 18 users only. Unfortunately, I was unable to reproduce this issue yet but one of my colleagues reproduced it once but haven’t been able to do it again since. The reports keep raising each day up to 1.3k events in the last 30 days now. Over release object This one has lower reports than the first one but I decided to include it since it might have relevant information regarding the first crash since the starting stack trace is similar. The crash timing seems to be similar to the first one, where we deallocate existing AVPictureInPictureController and later replace it with a new one and also found only in iOS 18 users which also refers to [AVPlayerController _observeValueForKeyPath:oldValue:newValue:]. I also was unable to reproduce this issue so far. Oh, and both of the issues happened on both iPhone and iPad. We’d appreciate any advice on what we can do to avoid this in the future and probably any hint on why it could happened. I have reported this issue with bug number: FB15620734 I also attached one sample crash report for each of the crashes here. non ui thread access.crash over release.crash

Submitted feedback FB17075016 Xcode 16.3 release macOS 15.4 iOS 18.4 / iPadOS 18.4 release builds Memory graph fails to build when targeting physical devices running release builds referenced above. Memory graph will build against a simulator device.

My app works perfectly the first time it is used but when returning to the start after playing the game and playing another it does some random things. I figure it is because the app still retains the previous game in it’s memory allocation? My question is, what is the best way programmatically to have an app start fresh and not have to quit it and open it again?

Hi, I am currently working on a MacOS App, where I need the undistortion function of opencv. But after I tried to add opencv to my project, I get following error: unexpected service error: The Xcode build system has crashed. Build again to continue. Cleaning the build folder also doesn't help. Does anyone have an idea what could be the issue? Ryan

I'm trying to build an MDLMesh then add normals let mdlMesh = MDLMesh.newBox(withDimensions: SIMD3<Float>(1, 1, 1), segments: SIMD3<UInt32>(2, 2, 2), geometryType: MDLGeometryType.triangles, inwardNormals:false, allocator: allocator) mdlMesh.addNormals(withAttributeNamed: MDLVertexAttributeNormal, creaseThreshold: 0) When I render the mesh, some normals are (0,0,0). I don't know if the problem is in the mesh, or in the conversion to MTKMesh. Is there a way to examine an MDLMesh with the geometry viewer? When I look at the variable values for my mdlMesh I get this: Not too useful. I don't know how to track down the normals. What's the best way to find out where the normals getting broken?

I am using a Mac computer running macOS 15.5 with Xcode version 16.3 (16E140) and an iPhone XS Max on iOS 18.5. When debugging my app on the real device using Xcode, the app gets stuck on the launch screen and fails to proceed to the main interface. There is no output in the Xcode console, and the top of the window continuously shows "attaching to [app name] on [iPhone name]". Here are the details: The same issue occurred when the phone was running iOS 18.4.1. When I tested on another real device running iOS 17, the app launched and ran normally. I’ve tried clearing the cache, but it didn’t help. I deleted the ~/Library/Developer/Xcode/iOS DeviceSupport folder, let it re-download the necessary files, and ran the app again, but the issue persists. I’m currently out of ideas and would appreciate any assistance.

We have an old iOS app and an old camera that connects using Wi-Fi either using an access point or Ad Hoc network, e.g., iPhone/iPad connects to the camera's Wi-Fi directly... How it works (old legacy app/system, which cannot be redesigned): Camera is configured to Ad Hoc Wi-Fi network (insecure TCP). iPhone connects to this insecure Wi-Fi. Camera uses Bonjour service to broadcast its IP address. App reads in IP address and begin to send messages to the camera using NSMutableURLRequest, etc. All this works fine for iOS 17. But in iOS 18 step 4 stopped working. App simply doesn't get any responses! We believe we have configured ATS properly (App Store version): In panic we have also tried this in Test Flight version: The latter actually seemed to make a difference when running the app on macOS Apple Silicon. But on iOS it didn't seem to make any difference. Occasionally, I was lucky to get connection on on iPhone 16 Pro with iOS 18. But for the 'many' iPads I have tried I couldn't. I also tried to install CFNetwork profile and look at the logs but I believe I just got timeout on the requests. Questions: Why it iOS 18 different? Bonjour works fine, but NSSURLRequests doesn't Do we configure ATS correctly for this scenario? What should I look for in the Console log when CFNetwork profile is installed? Should I file a TSI? Thanks! :)

Context I created a short script to CPU profile a program from the command line. I am able to record via the Instruments app, but when I try from the command line I get the following error shown below. This example is just profiling the grep command.

I have recently submitted a new app version to the Appstore with Xcode 15.0. Unfortunately, I have started to see the below crash in the Xcode organiser &gt; Crashes section occurring for more number of times. UIKitCore: +[UIAlertController _alertControllerContainedInViewController:] + 160 The exception trace is not leading to main() function but not pointing to any of the code line. I had used UIAlertController in the past versions to show the alerts but there is no code written in the current version code related to UIAlertController. Only from the latest version, this kind of crash started to surface. In the latest release, We have added a third party SDK and while implementing the SDK, we had added the Location and Bluetooth Permissions in Info.plist file. But as we don't want to use/track the Location and Bluetooth details from the app, the SDK team has disabled the Location and Bluetooth settings to not reflect in the tracked data. Is this behaviour creating any conflict with the UIAlertController and logging the crash? Because by default the OS tries to show the alert when the permissions exist in the plist file, but the alert will not come as the service is disabled on the SDK server settings. Is this creating any conflict and logging the crash. Please extend your help.

I noticed that when using .searchable inside a NavigationStack thats inside a TabView, the searchbar briefly overlays the content before disappearing. After that, it is hidden and appears as expected when swiping down. This only happens when the .searchable is inside the NavigationStack, there is at least one navigationTitle and the NavigationStack is inside a TabView. Tested on simulator and real device. I would appreciate any help. Thanks! struct FirstScreen: View { var body: some View { TabView { Tab("Tab", systemImage: "heart") { NavigationStack { NavigationLink { SecondScreen() } label: { Text("Go to second screen") } .navigationTitle("First Screen") } } } } } struct SecondScreen: View { @State private var text: String = "" var body: some View { List { Text("Some view that extends all the way to the top") } .searchable(text: $text) .navigationTitle("Second Screen") } }

We have a Privileged Helper tool that we install with SMJobBless. I would like to debug it. I've added WaitForDebugger in our helper tool launchd plist and it does wait. But I can't attach to it via Debug->Attach to Process in Xcode with error: Code: 3 Failure Reason: tried to attach to process as user 'myusername' and process is running as user 'root' I set Debug process as: root in scheme settings. But I'm not sure if it does anything since I'm not running this particular scheme at the moment of attach. I tried unsuccessfully to set "Wait for the executable to be launched" but I had to create a new scheme for it since helper is built as part of the main app so maybe I did something wrong. Am I doing something wrong or is it not possible to attach to root process?

I've got a problem with my app where I'm testing it on my own phone. I'm using audio kit to generate tones as part of the app. Everything seems to work fine. Sounds start, Stop, etc. They play when the app is closed and when the phone is locked, so background is working. However, I'm seeing an issue where, even when STOP is pressed and the application exited, if I get a notification such as a text message, the base tone for the app starts to play. If I then open the app, check the Start/Stop button - it says start so that. hasnt' been activated. If I click Start, then a 2nd tone starts. This one stops with the Stop button. However the original tone that was set off by an incoming message carries on playing. Until I go to the Open Apps View on the phone and slide the application upwards. For the life of me, I can't figure out whats happening here.

We've noticed a pretty common crash that's occurring in our app that appears to only be affecting iOS 18 users. The code in question is below: func getThing() async throws -&gt; ThingData { guard shouldRefresh, let data = self.thingData else { let remoteThingData = try await store.getThingData() self.thingData = remoteThingData return remoteThingData // Crash happens here } return data } The crash happens on a background thread and the actual crash is: Crashed: com.apple.root.user-initiated-qos.cooperative EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000004a67149c0 We haven't been able to reproduce the error ourselves but in the past 90 days all of the crashes (several thousand) have been only on iOS 18. We also found this thread that appears similar from 2 years ago but unsure if it's related because in our case the guard can only be calculated at runtime so there shouldn't be any optimizations happening.

Hello there! So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash. So I know the "it works on my computer" sounds bad but....works on my computer and my test system. Dont know what to do since I dont know how to replicate the error. This is the rely they sent me: Issue Description The app exhibited one or more bugs that would negatively impact users. Bug description: at time of review the app’s interface went blank at launch. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.4.1 Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.

My IAP and Subscriptions were rejected during review. I went to see what the problem was and it was due to my localization descriptions. So I removed Enlgish (Canada) no problem, created a new one, save. Then there was only one left which is English (US) but when I try to remove this last one, I get an error saying 'There was an error with deleting the localization. Please try again later.' when I try to delete it. This is happening for all my subscription and iap items, as well as the subscription group localization. Seems that when there are multiple rejected localization items in a table, you aren't able to delete the last rejected row regardless of language. Anyone else experience this? Any way to get around it? I would prefer not deleting my entire subscription group and iaps.

No matter what I do, I keep getting the error Thread 1: EXC_BREAKPOINT (code=1, subcode=0x2648fc364) for the line: transactions = try modelContext.fetch(descriptor) in the code below.
