Overview

Hi, I have two iOS apps in the same app group. Now App 1 wants to execute a method in App 2 via IPC: App 1 -> call method test() via IPC on App 2 -> App 2 returns the result to App 1. Is this possible? Regards,

OS Version: macOS 13.6.3 (22G436) Code Type: ARM64 We recently observed that the system extension process CPU based on networkextension (data-filter firewall) has been 99% busy for a period of time. We try to deauthorize data-filter so that the firewall stops working and the NEFilterDataProvider object is released. However, the system extension process CPU usage is always 99% busy. Then I used Instruments-CPU Counters to observe that a thread (thread id: 0x2abf9b) has been busy, but no useful backtrace information was captured. Through the sample command, I caught the backtrace and found that the busy process (thread id: 2801563 == 0x2abf9b) is in this state. 35 Thread_1336407 DispatchQueue_442: NEFilterExtensionProviderContext queue (serial) + 35 start_wqthread (in libsystem_pthread.dylib) + 8 [0x1a1afad94] + 35 _pthread_wqthread (in libsystem_pthread.dylib) + 288 [0x1a1afc074] + 35 _dispatch_workloop_worker_thread (in libdispatch.dylib) + 648 [0x1a1963244] + 35 _dispatch_lane_invoke (in libdispatch.dylib) + 384 [0x1a19585f8] + 35 _dispatch_lane_serial_drain (in libdispatch.dylib) + 372 [0x1a1957960] + 35 _dispatch_source_invoke (in libdispatch.dylib) + 1176 [0x1a1966ce0] + 35 _dispatch_source_cancel_callout (in libdispatch.dylib) + 204 [0x1a1967890] + 35 _dispatch_continuation_pop (in libdispatch.dylib) + 504 [0x1a1953884] + 35 _dispatch_client_callout (in libdispatch.dylib) + 20 [0x1a1950400] + 35 _dispatch_call_block_and_release (in libdispatch.dylib) + 32 [0x1a194e874] + 35 __75-[NEFilterDataExtensionProviderContext setupSocketSourceWithControlSocket:]_block_invoke (in NetworkExtension) + 112 [0x1b1e0dd74] + 35 close (in libsystem_kernel.dylib) + 8 [0x1a1ac0ac0] note: the picture screenshot and the text description backtrace are from different machines, but the problem is the same. This seems to be a newly introduced bug in the network extension? This problem did not occur for a long time between 10.15 and 10.12.

when using Xcode15, we found that using Xcode 15 to access keychain may fail. Although using Xcode earlier than 15 may have same question, but the probability is higher on Xcode15. Anyone has the same question and how to fix it?

Hello, I'm experiencing a sad BUG. I am deaf, blind, in a wheelchair. I program in XCode via Braille display. I compile any APP in XCode, including the APP test "Hello world!" and I transfer this APP to my iPhone via USB cable or Wi-Fi. So, when I try to enter the APP, VoiceOver suddenly deactivates itself and no longer activates. I always have to turn off my iPhone and turn it on again. He only reacts with someone he sees as helping. I'm not programming in XCode, because I can't test APPS on my iPhone anymore. Help me. Software in Mac: XCode 15.4 beta Software MacOS: latest version; Software in iPhone:iOS 17.5 Hardware: iPhone 14 Pro Max The BUG happens always.

What are the identifiers for these iPad models in 2024?

I start a project for iPad/iPhone and I set SwiftUI - RealityKit and I can’t get the build to compile. I do nothing but create a project and hit run. So I am wondering if it’s even possible to run RealityKit on just an iPad anymore. I then tried to use Reality composer to import a basic cylinder shape to my project and that wouldn’t run either. So I am wondering how to get a 3D model into my iPad app so that the user can interact with it. Thanks for any help

Hello, For a short time before and just after we announce our app we would like to make it available by direct link only. We don't want it to be searchable on the app store. Can anyone tell me if this is possible and if so, what the best way to do this is? Thanks

My application runs smoothly in our local environment. however, we consistently encounter errors upon launch in TestFlight. Despite our efforts to update our libraries and address these issues, the problem still persists. For more detailed insight, I have attached the crash log here.

[visionOS Question] I’m using the hierarchy of an entity loaded from a RealityKit Pro project to drive the content of a NavigationSplitView. I’d like to render any of the child entities in a RealityKitView in the detail pane when a user selects the child entity name from the list in the NavigationSplitView. I haven’t been able to render the entity in the detail view yet. I have tried updating the position/scaling to no avail. I also tried adding an AnchorEntity and set the child entity parent to it. I’m starting to suspect that the way to do it is to create a scene for each individual child entity in the RealityKit Pro project. I’d prefer to avoid this approach as I want a data-driven approach. Is there a way to implement my idea in RealityKit in code?

the file does not show a black fill but the app shows a black circle. since it's to long https://gist.github.com/YutaTheTraveler/0b8c11faf997f2118d19bbd009d490ba.js

Hello everyone, few months ago I submitted my new app for review, but got automated message back: We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time. thought it won't take long (I was wrong) , I waited for a whole month and nothing, then I started researching and some other devs suggested to cancel that submition and resubmit , and I did just that , same thing happened this time , almost 3 weeks that i've been waiting , if any one from apple sees this please help me :(

We're looking at mitigation options for the TunnelVisioning attack that exploits DHCP option 121 to set routes. It looks like Per-App VPN doesn't have the problem, but in standard mode we aren't able to touch potentially malicious host routes, so while we can mitigate it we can't eliminate the security problem completely. Is there any way to tell iOS and macOS to ignore DHCP option 121? Or even better, does Apple have a fix in the works?

This bundle is invalid. The value for key CFBundleVersion [1.0.1] in the Info.plist file must contain a higher version than that of the previously uploaded version [5]. Please find more information about CFBundleVersion at https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleversion (ID: 978303b8-eb71-4d71-9169-b0b0860fd8ec) The issue is an error while uploading macOS version 1.0.1 to the App store. If I want to solve it simply and quickly now, do I have to skip 1.0.1 and upload version 5.0.1 right away? I made an inquiry to Apple, but they only asked me to ask the forum or provide technical support. I would appreciate it if you could reply even if it's not accurate. I don't know if the problem is mine or Apple's problem, so I can't solve it for a long time.

Hi. I am new to ios development and I am using swift to try to develop a sample app to connect a Canon camera to an iphone via a usb cable and I want to use the ImageCaptureCore framework to do this (that is I want to use the USB PTP). Although I see the documentation on the Apple site, I am still unsure where to begin. Is there any tutorials, etc. about where I can get started with this? I was able to find a couple of code snipets and piece together something with ICDeviceBrowser but when I load the program onto my iphone and connect the camera via usb, I am not able to detect any camera. So ideally I am looking for some sort of tutorial that goes through how to do this or if not, what do I have to do to at least be able to detect the camera from the iphone?

I've added a recurring leaderboard in App Store Connect which I can get the localized title from, submit scores to, and load players from, but I'm getting an error whenever I try loading the image for it with the instance method for GKLeaderboard, loadImage(). The description from the error is: The requested operation could not be completed due to an error communicating with the server. Both the completion block and async versions of this method yield the same result. I made sure the image is a PNG in 1024x1024, 72 DPI, and in the RGB colorspace. No errors appear after I upload the image. Are there any hidden requirements that might be causing this error? Perhaps there is a waiting period before the server can provide the image?

Currently in an app I am working on, we are adding collision shapes/components to objects by using the ShapeResource.generateConvex method to generate the shape from the mesh of our ModelEntity. Unfortunately, this does not result in a totally accurate collision shape. The following example is how the collision component looks currently. Is there anyway to generate a collision shape that fits the exact bounds of the ModelEntity?

Hi, we are a Carrier company (Utility provider) and working on a feature to display real-time Wifi Signal strength of customer devices (connected to Router Gateway) to help customers identify low and high signal areas, and possibly install extenders to improve signal strength at weak points. This feature requires NEHotspotHelper entitlement approval to access signalStrength property. We went through this Apple documentation too and we're open to other recommendations from Apple https://developer.apple.com/forums/thread/721067 . Since we currently don't have direct point of contact with Apple to discuss this requirement, hence wanted to check it here. Kindly advise. Thanks !
