Hi, there's this point at which a beginner needs to beg for help. Unable to open mach-O at path: /Library/Caches/com.apple.xbs/Binaries/RenderBox/install/Root/System/Library/PrivateFrameworks/RenderBox.framework/default.metallib Error:2 I get this everytime I select a month and year on a custom date picker, I believe because I try to force the ".generateChartData()" for the chart to update. I guess the problem might be that the ".onAppear" and ".onChange" are conflicting with each other? } .onChange(of: showDatePicker) { viewModel.startDate = selectedDate viewModel.generateChartData() } } .onAppear { viewModel.generateChartData() }

Hi, everyone I have an app already in production that uses SwiftUI's lifecycle (paired with an AppDelegate). Due to some specific behaviour of the app, we decided to migrate the app to use UIKit's lifecycle, adding the corresponding SceneDelegate to the app, as well as modifying the Info.plist file accordingly to accommodate to these new changes. Although everything seems to work when installing the app from zero, when installing it on top of another version, the screen goes black and the user cannot interact with the app at all unless they reinstall it completely. As I've read online, iOS is reusing the window configuration from the previous execution of the app. I know this because the AppDelegate's application(application:connectingSceneSession:options) is not being called when coming from a previous version of the app. I would love to know what can I do to make this work because, as you may understand, we cannot ask our user base to reinstall the application. Thank you very much.

Hello everyone, I’m experiencing a crash in my iOS application that’s occurring predominantly on devices running iOS 16.6.0. The crash seems to happen on the main thread during a UI operation, specifically within the UIKitCore framework.

Hello, I am experiencing crash on TopShelf and I checked all the crashlogs, but I don't know how to interpret it. I see only addresses in the trace logs, so it's really hard to understand what's going on. Is there a way how to symbolicate frames 5 - 17? Does anybody have an idea, what can be wrong?

Hi, I’m encountering an issue while using xctrace & instruments to profile an application on macOS. Specifically, when trying to record a trace using the CPU Profiler template, I get the following errors: Failed to start the recording: configureHardwareCounters: Failed set kpc configuration: Operation not permitted. Unexpected failure: Couriers have returned unexpectedly. macOS Version: 15.3.1 Chip: Apple M4 Pro Xcode Version: Xcode 16.2

I have a few crash report from TestFlight with this context and nothing else. No symbols of my application. Crash report is attached. crashlog.crash It crashes at 16H25 (local time paris) and a few minutes after (8) I see the same user doing task in background (they download data with a particular URL in BGtasks) with a Delay that is consistant with a background wait of 5 or 7 minutes. I have no more information on this crash and by the way Xcode refuses to load it and shows an error. ( I did a report via Xcode for this).

I have an issue when i use external tester with a public link and emails. Test fly is well installed but when i have to open the app, it just charge as seen in the screen.

Background I have a SwiftUI app that uses OSLog and the new Logger framework. In my SwiftUI views, I would like to use something like Self._logChanges() to help debug issues. After some trial and error, I can see the messages appear in the System console log for the app I am debugging using the com.apple.SwiftUI subsystem. Problem I'd like to see those same messages directly in Xcode's console window so I can filter them as needed. How do I do that? Thanks! -Patrick

When the following structure: NavigationStack { ScrollView { NavigationLink(...) } } is presented inside a sheet in SwiftUI, the scroll drag gesture and the link tap gesture collide. If the user happens to begin a scroll gesture on a link, the link will open the moment the finger is lifted, no matter how far it is from its initial touchdown. The issue has already been found (this stack overflow post from 2019), but no solution was provided. I've already filed a report (FB17034020). In the meantime, is there any way to override the touch gesture detection in any manner? This issue is quite inconvenient from a user perspective.

Pasting either plain or styled text into any TextEditor results in a memory leak. import SwiftUI struct EditorView: View { @State private var inputText: String = "" var body: some View { VStack{ TextEditor(text: $inputText) .frame(minHeight: 150) } } }

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.

I’m so lost on this. I’ve tried Google, ChatGPT, DeepSeek, the documentation. I’ve spent about 7 hours on this specific bug. Not sure what to do next. Does anyone have an idea?

I was just having a look at some crash reports downloaded by Xcode, and I noticed the same wrong pattern I already mentioned here: the crash reports indicate that method A calls method B, which is impossible. In the first crash report below, method MainViewController.showSettings seems to be called by ConfirmMoveViewController.openSourceInFinder, which is impossible. ConfirmMoveViewController.openSourceInFinder is a context menu action in a modal window, and MainViewController.showSettings is in a completely different window and the two methods have no relation whatsoever. In the second crash report below, MainViewController.setSortMode is triggered by the press of a button (and nothing else) but seems to be called by OtherViewController.copy that can be triggered by a context menu (or keyboard shortcut). The two methods have no relation whatsoever. The rest of the stack trace confirm that it's indeed the button that was pressed. This seems to me like a quite serious bug in how macOS creates crash reports. 1.crash 2.crash

We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app. Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive. We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts. Actions Performed During App Launch: Firebase configuration API requests, including: Fetching account details Registering the FCM token with the server Asynchronous background requests to fetch POI details Creating a local database and storing POI data in local storage We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated. Steps to Reproduce: Install and launch the app on an affected device. Observe that the app gets stuck on the launch screen. After some time, the app terminates unexpectedly. Issue is inconsistent and occurs only for certain users. Presence of other ELD apps running in the background appears to influence the issue.

I have found a system bug with UINavigationController, UIGestureRecognizerDelegate mainly the swipe back control. I have reproduced this in many apps, while some that use custom swipe back i can not reproduce, however any app using default uikit/swift transitions i can reproduce the flicker/previous screen flashing The Bug: a slight tap or series of quick taps anywhere on the screen (with the slightest (1-2pt -x)confuse the system into thinking its a swipe back gesture, however instead of pushing back to previous screen the UI flickers and flashes the previous screen. for a split second, very easy to reproduce. on screens with lots of options of boxes to tap it happens quite often. I have removed all custom "swipe back from anywhere" logic, all custom gesture logic, and can still reproduce by tapping the edge of the screen with only UINavigationController, UIGestureRecognizerDelegate in my navigation controller. Please let me know the best way to get in contact with someone at apple to either build an extension to prevent this flicker or if a developer has a fix but this is rarely talked about. (velocity limits etc do not work, and just make the gesture feel awful) all the developers i have reached out too have looked into this and have said "its an ios bug, only fix is build a custom swipe back from anywhere, or wait for apple to fix it).... as a small indie app, building my own seems daunting Recap: quick or taps with small x movement flash previous screen instead of pushing back or simply recognizing it as a tap and not flashing previous screen. this happens with no custom code default uikit/swift. Link me your app i can probably reproduce it, I have reproduced it in X(was hard), Retro(easy), and many more. The goal is to have a smooth native swipe/drag back from anywhere gesture while preventing flicking on fast taps or short taps with minor x movement. i have tried everything from setting limits to -x, velocity limits etc. nothing fixes this. happy hacking! PS i hope someone at apple calls me and i can explain this and we can fix it for every app in an update.

Hi, I’m experiencing an issue where my React Native (Expo) app crashes immediately in TestFlight after launching, but it works fine in Expo Go and the iOS Simulator. This is my first time building an IOS app, so I'm not sure where I'm going wrong. Are there known issues with JS bundle loading, native module compatibility, or API entitlements that could be causing this? What tools or logs should I use to track the exact source of failure? Any guidance would be greatly appreciated! Thank you. Steps Taken: The app runs fine in Expo Go (npx expo start --no-dev --minify) and in the iOS Simulator (npx expo run:ios --clean). I also did (npx expo-doctor) and it passed all 15 checks. After building with EAS (eas build --platform ios --profile production), the TestFlight build crashes on launch. I checked Xcode logs (Devices & Simulators > View Device Logs) and found this error: `Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: SIGNAL 6 Abort trap: 6 Terminating Process: LoungeNavigator [4666] Triggered by Thread: 6 Thread 6 name: Thread 6 Crashed: Thread 6 crashed with ARM Thread State (64-bit): x0: 0x0000000000000000 x1: 0x0000000000000000 x2: 0x0000000000000000 x3: 0x0000000000000000 My app.json file: "expo": { "name": "appname", "slug": "app", "owner": "baint", "version": "0.5.2", "orientation": "portrait", "icon": "./assets/images/IOS-App-Icon.png", "scheme": "myapp", "userInterfaceStyle": "automatic", "newArchEnabled": true, "ios": { "supportsTablet": true, "bundleIdentifier": "bundleIdentifier", "icon": "./assets/images/IOS-App-Icon.png", "buildNumber": "7", "infoPlist": { "NSLocationAlwaysAndWhenInUseUsageDescription": "This app requires access to your location at all times.", "NSLocationAlwaysUsageDescription": "This app needs your location even when the app is in the background.", "NSLocationWhenInUseUsageDescription": "We need your location.", "ITSAppUsesNonExemptEncryption": false } }, "android": { "adaptiveIcon": { "foregroundImage": "./assets/images/IOS-App-Icon.png", "backgroundColor": "#ffffff" }, "package": "identifier" }, "web": { "bundler": "metro", "output": "static", "favicon": "./assets/images/favicon.png" }, "plugins": [ "expo-router", [ "expo-splash-screen", { "image": "./assets/images/IOS-App-Icon.png", "imageWidth": 200, "resizeMode": "contain", "backgroundColor": "#ffffff" } ], "expo-asset", [ "@rnmapbox/maps", { "RNMapboxMapsImpl": "mapbox", "ios": { "RNMapboxMapsDownloadToken": "token", "RNMapboxMapsAccessToken": "token", "NSLocationAlwaysAndWhenInUseUsageDescription": "This app requires access to your location at all times.", "NSLocationAlwaysUsageDescription": "This app needs your location even when the app is in the background.", "NSLocationWhenInUseUsageDescription": "We need your location." } } ], [ "expo-build-properties", { "ios": { "useFrameworks": "static", "useModularHeaders": true } } ] ], "experiments": { "typedRoutes": true }, "extra": { "router": { "origin": false }, "eas": { "projectId": "projectid" } } } } My eas.json file: "cli": { "version": ">= 14.7.1", "appVersionSource": "remote" }, "build": { "development": { "developmentClient": true, "distribution": "internal" }, "preview": { "distribution": "internal" }, "internal": { "distribution": "store", "ios": { "credentialsSource": "remote" }, "autoIncrement": true, "env": { "EXPO_PUBLIC_NODE_ENV": "production" } }, "production": { "autoIncrement": true, "distribution": "store", "env": { "EXPO_PUBLIC_NODE_ENV": "production" } } }, "submit": { "production": { "ios": { "ascAppId": "ascAppId", "appleId": "appleId", "ascApiKeyPath": "ascApiKeyPath" } } } }

When apple pay on the web does a onshippingcontactselected it appears to truncate the zip code. If I enter: 11111 or 11111-1111 I always get 11111. Is there any way to get the plus 4?

I am working on an XCode project and I have some Swift functions within a helper functions file. This file has some functions declared that create 3 global variables. These global variables are then used in various views throughout the app. In the functions, there are print statements for when it catches an error. However, when I run the app and I get an error that stems from this file, there are no print statements. How can I have this print statements show up in the debug console?

When I toggle a panel like navigationsidebar, I get a message in the console. I guess it's not a big issue, but is there a way to fix this message? because it appears in every project.
