Sandbox: bash(5261) deny(1) Issue in Xcode
I'm a complete newbie to building an App, this project is a GUI that interacts with an LLM AI service, it's mostly html, javascript, python. I have something that works in a web browser, and mostly works in Android Studio, but in Xcode there are numerous issues. It's my understanding this is something to do with permissions. I have asked an AI which suggested various things that haven't worked, such as reinstalling Cocoapods, and disabling SIP. Are you smarter than an AI, or at least better informed? If so, suggestions or advice would be appreciated. Sandbox: bash(5261) deny(1) file-read-data ........./ios/App/Pods/Target Support Files/Pods-App/Pods-App-frameworks.sh

Iphone 14 & 15 pro model camera focusing error / UNITY APP
Hi, I would like to ask your advice with our IOS app, which has a problem with the Iphone 14 pro & Iphone 15 pro model camera focusing on close objects. The game is made with Unity and the idea is that kids can scan random QR - and barcodes to catch monsters. With Iphone the no pro models focus and read the barcodes well, but new models with three back camera systems our app does not focus on close, that makes the barcode reading hard. Somehow it seems that the Iphone pro model is not changing the camera lens to close focusing one in a third party app like it does when you use the camera itself. Do you have any advice on how to solve the focusing problem? I appreciate your help!

I tried to add a overlay window onto app in full screen mode but failed
As the topic mentioned, I want to add a overlay window onto Apps that are in full screen mode, trying to create some blur effect on the screen. But Apple seems to treat full screen mode Apps differently as a "space." So currently I can only apply the blur effect like this. (This is my Desktop page) But When it doesn't affect the full screen mode Apps. (For example: My Xcode) And I know some of the App down this kind of stuff. Like this This is my current code. Hope someone can tell me how to solve it.

React-Native iOS app is crashing immediately upon launch when creating development build
I have created an app for iOS using React Native. I've gotten the app to a point where it works on the iPhone simulator via the Expo App. It even works when creating a build of the app to distribute using TestFlight. Now, I want to add Google Ads into the app. However, I've learned that Google Ads won't work via an Expo build. Instead one has to create a development build to test the ads in the app and see how they look. I've also finally been able to compile a successful development build using eas (expo application services). When I install the app on the simulator and try to open it however, the app crashes almost immediately and I don't know why. I have tried deciphering the symbolicated crash report, but I have not been able to figure out what could be causing the error. It looks like it has something to do with the user interface. Below is the thread where the app crashes: Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x11324a14a __pthread_kill + 10 1 libsystem_pthread.dylib 0x1132abebd pthread_kill + 262 2 libsystem_c.dylib 0x7ff80016dd1c abort + 133 3 libc++abi.dylib 0x7ff8002c6d12 abort_message + 241 4 libc++abi.dylib 0x7ff8002b951a demangling_terminate_handler() + 266 5 libobjc.A.dylib 0x7ff800061fba _objc_terminate() + 96 6 libc++abi.dylib 0x7ff8002c616b std::__terminate(void (*)()) + 6 7 libc++abi.dylib 0x7ff8002c6126 std::terminate() + 54 8 libdispatch.dylib 0x7ff8001796ec _dispatch_client_callout + 28 9 libdispatch.dylib 0x7ff80017d1e2 _dispatch_block_invoke_direct + 508 10 FrontBoardServices 0x7ff807a8b3a7 __FBSSERIALQUEUE_IS_CALLING_OUT_TO_A_BLOCK__ + 30 11 FrontBoardServices 0x7ff807a8b281 -[FBSMainRunLoopSerialQueue _targetQueue_performNextIfPossible] + 188 12 FrontBoardServices 0x7ff807a8b3cf -[FBSMainRunLoopSerialQueue _performNextFromRunLoopSource] + 19 13 CoreFoundation 0x7ff800429ff3 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 17 14 CoreFoundation 0x7ff800429f35 __CFRunLoopDoSource0 + 157 15 CoreFoundation 0x7ff800429732 __CFRunLoopDoSources0 + 215 16 CoreFoundation 0x7ff800423e67 __CFRunLoopRun + 919 17 CoreFoundation 0x7ff8004236ed CFRunLoopRunSpecific + 557 18 GraphicsServices 0x7ff8103ba08f GSEventRunModal + 137 19 UIKitCore 0x7ff805cdf6ee -[UIApplication _run] + 972 20 UIKitCore 0x7ff805ce416e UIApplicationMain + 123 21 LeftOff 0x10f870380 main + 96 22 dyld_sim 0x112d3a3e0 start_sim + 10 23 dyld 0x113d57366 start + 1942 I have been trying to solve this for some days now and could really use some help. I have tried changing versions of dependencies in my app too, with a focus on those that manage the UI. For example, I have changed packages such as react-native-ranimated, react-navigation/stack, react-native-gesture-handler, and react-native-screens to name a few. Nothing has worked so far. Please help.

App crash on iOS 16.7.8 installed by mdm
Hello, I have a problem with an iOS app that is deployed via the MDM system Intune. The app closes immediately after starting. The APP works without distribution via the MDM. Devices with iOS 17 also work. I am attaching a crash report. (txt is ips) Unfortunately I have no idea how to solve the problem because it only occurs via the MDM and therefore I cannot debug it. The problem occurs in production environment. Please help me with the solution. Insight Mobile-2024-06-24-144828.txt Best regards Moritz

iOS 17.5.1 only: STWebpageController loadView crash due to NSInternalInconsistencyException
Hi there, We recently released our app and got one production crash that can not be reproduced by our developers. It happens only on iOS 17.5.1 and the crash seems to be related to STWebpageController init at app start. The crash number is increasing fast but we have no idea about why it happens.

How to attach to Privileged Helper as root?
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?

Unreal 5.3 build failed, copied project from windows pc
I am having problems building an Unreal project in Xcode. The problem starts when the compiler starts to build a custom made plugin, that works perfectly fine on windows.

Bug Accessing Multiline SwiftUI TextFields in UITests
Hello, I am wondering if anyone else has seen this bug: Create a multiline TextField like so: TextField("a string", text: $myDataStore.placeholder, axis: .vertical) .accessibilityIdentifier("placeholder") .multilineTextAlignment(.leading) .lineLimit(...3) .textFieldStyle(CustomTextFieldStyle(text: $myDataStore.placeholder, hasErrors: myDataStore.placeholder.isEmpty)) Then create a UITest that accesses it. let multilineTextField = app.textViews["placeholder"] // note that multiline textFields can only be accessed as textVIEWS, not textFIELDS. They simply do not appear under po.textFields let exists = multilineTextField.waitForExistence(timeout: 3) XCTAssertTrue(exists, "The field did not appear in time.") multilineTextField.tap() // everything is fine up to here //BUG: multiline textfields will not tap into keyboard on larger device types like the iPhone 15, but they will on SEs. multilineTextField.typeText("A Test") // fails on anything other than an SE, "Neither element nor any descendant has keyboard focus" What is happening here?

Screen Time Crash. IOS 18 Dev Beta 1
I have experienced a consistent bug with screen time in IOS 18 DB1. It just doesn’t work, but the limits still function. I cannot access screen time settings (it just crashes) nor can I disable screen time from within a blocked app itself. Have not found any workaround. I have logged a feedback report, FB13932765 (Unable to open screen time settings, it just crashes) I Hope this can be looked at and resolved by the next update. Thanks, Felix
