App Sandbox and the loading of libraries written at runtime
We're interested in adopting App Sandbox in an app distributed outside of the Mac App Store. However, we're hitting a bit of a roadblock and it doesn't seem like either of the techniques described in that post can be used in a reasonable way. For background, this is a third-party launcher for a cross-platform Java game that, among other things, makes it easier for users to mod the game. Users generally download mods as .jar files and place them in a certain directory. In some cases, these mods contain native dynamic libraries (e.g. a .dylib) as part of their code. In general, the .dylib is extracted from the contents of the .jar to some temporary location, loaded, and then deleted once the game closes (the exact details, like the actual temporary location, depends on the mod). App Sandbox greatly interests us in this case because it can limit the damage that a compromised mod could do, and in my testing the functionality of most mods still works with it enabled. However, sandboxed apps quarantine every file t

Encounter "zsh: trace trap" after updating trust settings for Apple certificates
Hi guys, New to publishing apps on Apple Store. I encounter some notarization error before and resolved it in this post. By solving the previous issue, I updated the Trust setting from Always Trust to Use System Defaults for Apple certificates. The codesign and notarization no longer give me any problem. But now, I encountered another issue. When I ran the .app on my local Macbook, it now gives me zsh: trace trap error. Dive a little further and check the crash report, I found the some details as following. Process: my_app [30652] Path: /Users/USER/my_app_path Identifier: my_app Version: 0.0.0 (???)

Reply to FRONTBOARD crash App killed while running in the background.
I don't see details in the crash report (such as a Termination Description) that could guide me to address the issue. So I would appreciate it if you can give me some insight on what could be causing this. The key detail here is: Termination Reason: FRONTBOARD 0xbaadca11 Which means: 0xbaadca11 (3131951633) — pronounced bad call The operating system terminated the app for failing to report a CallKit call in response to a PushKit notification. I assume that since the app was awakened by a VoIP push, those background notifications won't count towards the iOS restriction of not getting too many background pushes: Correct. There isn't any restriction or limitation on the number of VoIP pushes that can be sent to an app and, indeed, the main reason the CallKit reporting requirements were introduced is that VoIP pushes were being widely abused and we didn't want to artificially limit push volume. However... Those pushes are delivered within 30 seconds after the call starts. ...I think using PushKit for thi

FRONTBOARD crash App killed while running in the background.
PLATFORM AND VERSION iOS Development environment: Xcode 16.2, macOS 15.5 Run-time configuration: iOS 18 DESCRIPTION OF PROBLEM Our app (a VoIP and messaging app) has been experiencing a crash when running in the background for long periods of time (a couple of days) while receiving calls, and message notifications. If the app is not receiving notifications, we don't get any crashes while it runs in the background. It is worth mentioning that we have several pushes that are background pushes and they could happen depending on the outcome of an incoming call. We have the two pushes: incoming call bye: let the app know that the calling end hanged up the call. incoming call answered: lets the app know that another device (with the same shared number) answered the call (web app, Android). Those pushes are delivered within 30 seconds after the call starts. I assume that since the app was awakened by a VoIP push, those background notification won't count towards the iOS restriction of not getting t

Reply to Endpoint Security Framework deadline
When testing with the Endpoint Security Framework for the AUTH_OPEN event, I found that the deadline was 15 seconds, but the actual process termination occurred at 5 or 6 seconds. Is this intended? That depends on what you mean by intended... In terms of why you're seeing that difference, the basic issue here is a disconnect between what the deadline actually means and the information available to your ES client. At a very high level, the deadline describes how long the system will stall that particular syscall. You can visualize that processing sequence as something like this: The in kernel receives the syscall and does its processing The in kernel ES system sets the deadline and calls out to user space. Time passes Your ES client receives the event and does its processing. Your ES client sends its response. Time passes. The in kernel ES system receives your response and completes the syscall. The disconnect here is that what the deadline describes is the time between 2 and 7, but the ONLY part of that proce

Reply to SMAppService daemon not running
It sounds like your launchd job is failing to start. There are two common reasons for that: launchd tries to start it and it crashes. launchd is unable to start it. A good place to… ahem… start is to look for a crash report. In the first case, and many times in the second case as well, a failure will generate a crash report. If that doesn’t show up anything, add a ‘first light’ log point to your job [1]. Then try to communicate with the named XPC endpoint. That’ll divide the problem in half: If you see a log entry, you know that your job started and you can debug your code. If not, you know that your code never got running and you can debug your configuration. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com [1] I explain this ‘first light’ concept in Debugging a Network Extension Provider.

Reply to pas_panic_on_out_of_memory_error crash on tvOS 15.4 and 15.4.1
@DTS Engineer I think that I got general understanding of the issue that occurs. In our application we still depend on TVML Kit (which is marked as deprecated already). On many screens we use the stackTemplate with collectionList that contains big numer of shelfs (10-20) with lockups that allow to horizontally scroll the rows. Based on investigation of what is going on with memory I see that TVML engine does its best to speedup the process of rendering the lockup elements to provide the best experience while doing the quick scroll through the all shelfs. To handle it, the TVML uses some kind of rasterisation mechanism for TVML elements and display them as a single image in TVStackedImageView. It leads to issues in case of using the first generation of apple TV as rastered elements are kept in memory as long as the template keeps alive. There is a big difference in memory consumptions in case of using 4k display and 1080p. It seems to be related to fact that created images for 4K displays are bigger and in res

Can developers use spatial image in third App's Spatial widget
Spatial widget is a new feature of visionos 26. I notice The system’s Photo app can add a Spatial Image in the widget. I wonder if third apps can use spatial image or any 3D content in it's widget? I try to use RealityView in widget and it run with a crash. So does spatial Image in widget only supported by the system Photo app, and not available to developers now?
