Can I get notified when my watchOS app is terminated by the system (e.g. watchdog)?
Hi all, I’m developing a watchOS app and have seen cases where the app is terminated by the system — for example, due to CPU usage limits being exceeded (watchdog termination). Here’s a portion of one of the crash reports: Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: CAROUSEL 2343432205 <RBSTerminateContext| domain:10 code:0x8BADF00D explanation:[app<app_name>:898] Failed to terminate gracefully after 5.0s ProcessVisibility: Foreground ProcessState: Running WatchdogEvent: process-exit WatchdogVisibility: Foreground WatchdogCPUStatistics: ( "Elapsed total CPU time (seconds): 11.280 (user 9.800, system 1.480), 100% CPU", "Elapsed application CPU time (seconds): 5.162, 46% CPU" ) reportType:CrashLog maxTerminationResistance:Interactive> My questions: 1.) Is there any way to get notified (via Crashlytics, Xcode Organizer, or any other reporting mechanism) when this type of system-level termination happens — similar to how we’re notified of crashes? 2.)Is there any way for a watchOS app to receive runtime warnings from the system when it’s about to exceed CPU or memory limits — similar to UIApplication.didReceiveMemoryWarningNotification on iOS? Thanks in advance!

Portal of Apple for tracking health(crashes/hangs)
We are looking for a platform or portal provided by Apple that allows us to track crashes, hangs, or other runtime issues faced by users while using our iOS/macOS application. This is similar to how we currently use Windows Error Reporting (WER) for our Windows application. Important note: Our application is not distributed via the Apple App Store — it is delivered through enterprise distribution or ad-hoc provisioning.

Not seeing any recent crash reports although there should be some
For my app Find Any File, of which both releases and TestFlight betas were released many times, the TestFlight page tells me that several users have submitted crash reports. And I'm sure the same is true for the MAS releases: (Yes, this shows quite recent ones, but I've seen similar supposed crash report submits in this list before.) However, the actual "Crashes" listing on the appstoreconnect sites hasn't show any new crash reports for many months now: (This is the entirety of crash reports I can get listed, even when removing all filters.) Something appears to be stuck, on Apple's end. The same issue is with Xcode's Organanizer window, for "Crashes": It also used to list only the same very old reports and nothing since May 2024. And just now, when I retried this in Xcode, I'm shown a weird error message I never saw before: Error Downloading Crashes List An error occurred… Access Restricted with adam id: 1207815783 And yes, I'm logged in just fine, under Prefs / Accounts. How am I going to get this investigated? I had already sent an email about this to the Review team, who didn't react to it at all. DTS is only for Code level support, which this isn't. Any help?

Immediate crash of Apple Watch simulator when typing a key
I get a crash in Apple Watch simulator (Series 9 45mm 18.0) as soon as the app launch if I type anything on external keyboard (just hitting command key for instance to capture a screenshot). Same crash on series 7 (45mm, OS 18.1) But app works normally when I use mouse to interact with the app on simulator. App does not crash on real device (Watch 4 OS 10.4.1). Nor does it crash on Series 6 simulator (44 mm OS 17.4). Here are the log I could collect (apparently, they contain sensitive language !!! so I attach as a file.: Attached logs

NSUbiquitousContainers
I'm using Xcode 16.3 and I want to add the key "NSUbiquitousContainers" but I cannot do it in the Entitlements file, it should be in info.plist file! I have done it before but in previous versions of Xcode when the info.plist was in the project navigator. However, now I cannot find the file and I did not find any way to create it! Please guide me in detail how to proceed (I'm not new to Swift or SwiftUI but not familiar to project settings)?

iOS Sdk Version vs iOS Version
When you update XCode it updates the sdk version, but do changes in the sdk take effect for apps running in a lower iOS version or only the corresponding iOS version or higher? For instance, https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18_1-release-notes Do changes listed in the notes only happen for apps that are running on iOS 18.1 devices or on any device with the app compiled against the 18.1 sdk version? Am I the only person who finds the docs totally unclear on this?

Building an app with both GUI and Command Line versions
I use CMake for my builds not the XCode GUI. I want to be able to build a single .app that contains both the GUI version and the command line version. I have seen products that ship both as part of the same .app (e.g. CMake) so this is clearly entirely possible, the 64k question is HOW? Right now I am building them as separate apps - lets call them DSS and DSSCL (*). The code base for each is in its own directory - each with its own CMakelists.txt file. My initial thoughts are to change the build for DSSCL so it doesn't create a bundle and then simply copy the DSSCL command and related .qm files into DSS.app/.../MacOS. However that's likely enough totally wrong, so how should I handle this please. As much detail as possible please, I am very new to macOS development -please don't assume knowledge of stuff that's second nature to you Many thanks David (*) Strictly they are DeepSkyStacker and DeepSkyStackerCL

Simulate Background Fetch Not Working on Real Device, Works on Simulator
Hello Apple Support, I’m facing an issue with Background Fetch in my React Native project. When I click on Simulate Background Fetch in Xcode, everything works as expected on the iOS Simulator—background tasks run smoothly, and data is fetched without issues. However, on a real device, the app goes to the background but doesn’t execute any of the scheduled background tasks, and it also remains in the background without terminating. Here’s some additional context: React Native Project: I’m using React Native to develop this app, and the background tasks involve: Getting User Location: Fetching the user’s location in the background. API Calls: Calling an API to fetch necessary information based on the user’s location. Scheduling Notifications and Alarms: Scheduling notifications and alarms based on the API response data. Simulator vs. Real Device: In the iOS Simulator, all these background tasks trigger and function correctly when I simulate Background Fetch. On the real device, however, none of these tasks are triggered when I try to simulate Background Fetch. The app only moves to the background without performing any tasks or getting terminated. Device and Configuration Details: iOS Version: 17 Device Model: Iphone xs, Iphone 11, iphone 7 Background Modes: Background Fetch is enabled in Capabilities, and I’ve set the fetch interval to the minimum for testing. I’ve verified that all configurations are correctly set, and I’ve tried restarting the device and Xcode, but the issue persists. Is there something specific about Background Fetch that could prevent it from functioning as expected on physical devices? Any guidance on troubleshooting or additional steps would be highly appreciated. Thank you!

Lost X Code Project for a Live Application
Hello, I currently have a live application in the iOS App Store that needs an update to start functioning again, but I've lost the source code in a hard drive failure. Is there a way to reverse engineer the currently deployed package that is live (and also a way to download it from App Store Connect)⁉️ The development change itself is just a very small change for an API route in the code itself. I could even direct an engineer at Apple to make the change in 5 minutes! Let me know if this is possible. Thanks❗️

I received hardly any response to my DTS ticket - What to do?
About three weeks ago I submitted a DTS ticket (13097367) to receive code level support with a potential SwiftUI bug. At first I did not receive any response at all (beside the automatic confirmation that the ticket has been created). Only after posting the question here, I got a reply from a DTS engineer. However, the proposed solution did not really solve the problem but only circumvents it (UI freezes when ScrollView reaches below SafeArea. Solution: Do not use ScrollView below SafeArea...) I pointed out, that this does not really help me. Since then I did not receive any further response. Is this normal? Is there something wrong with my ticket? Maybe it was closed by accident or something? Thank you very much!

Missing Sources in Apple OSS Distributions
I noticed that there are numerous missing source repositories. For instance: https://github.com/apple-oss-distributions/IOHIDFamily/blob/07b14847cb5b4e0f826a3970961624969e443a6e/IOHIDFamily.xcodeproj/project.pbxproj#L4274 Many files referenced in the xcodeproj are listed but do not actually exist in the repositories.

Create Ios app using Xojo
I have created and Ios app using xojo, and run using the Xcode simulator. I want to test it on my phone and don't seed to put it on the app store as it is for personal use. I've seen pages that indicate a free apple developer option is available for a limited time but can't for the live of me get my app to actually run on my phone. I've tried both apple configurator and xcode to add my app with no luck

Associating file extension with my application
My application uses a text file with an extension of .dssfilelist. On Linux I would register the Mime type and associate it with the application in the .desktop file. <?xml version="1.0" encoding="UTF-8"?> <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"> <mime-type type="text/dssfilelist"> <comment>DeepSkyStacker file-list file</comment> <glob pattern="*.dssfilelist" /> </mime-type> </mime-info> I believe that I need to add stuff to the Info.plist for my application, but I also understand that CFBundleTypeExtensions is deprecated. So please could you show me what I now need to add to the Info.plist file so that these files will be registered as "text/dssfilelist" type and associated with my application and to associate a .icns file with it?
