Hello everyone! My app is getting a crash in the tableView(_:trailingSwipeActionsConfigurationForRowAt:) function. Apparently, the app is crashing when trying to get the indexPath.section value. I am attaching the crash log. This is not reproducible for me. I have the hunch that this might be related to some accessibility feature, but I have not been able to corroborate it yet. I am not sure how to solve this issue or how to move forward since I still don't know what is causing the app. Any advice or guidance is really appreciated. Thank you!

I have added crash log, code is working perfectly fine when I compiled with XCode 11.6 & iOS 13 and iOS 14 also. But When I am compiling with XCode 12 and run on iOS 14 device. it will start crashing. Crash log - https://developer.apple.com/forums/content/attachment/e42cb9be-15b7-4fe7-b608-6008f7353aa1

My team is working on the arm64/universal conversion of a large application with lots of third-party dependencies, but while that work is in progress we are trying to support customers running the app under Rosetta on M1 macs. To that end it will be helpful if we can actually debug the x86&#92;&#95;64 build running under Rosetta on M1, but we see lots of instability when we try this. The app will not even launch if the thread sanitizer setting is turned off. Sometimes the app still fails to launch and/or the debugger fails to attach. It will sometimes show the error message "LLDB provided no error string". No breakpoints are hit during attempted debugging. Note the app is a plugin host, and we sometimes see a main queue crash on ImageLoader::recursiveInitialization when we attempt to debug. Is debugging a non-trivial x86&#92;&#95;64 app under Rosetta on an M1 machine supported by Xcode? Are there any special configuration steps to get it to work? (We can debug a trivial Hello World x86&#92;&#95;64 app fine this way so it seems to be related to more complex app architecture). Also FWIW we tried launching Xcode itself under Rosetta on the M1 machine as well to see if that would resolve any debugging conflicts, but it didn't correct these issues. Thanks for any guidance!

Short story: My SwiftUI app (let's say the name is *MyApplic*) is working on hundred of Apple devices (iPhone and iPad) like a charm. But at least 3 persons are concerned by a mysterious crash when they made the same action (navigate to an other view). Obviously, I can't reproduce this crash on devices I have... And of course, different devices and iOS versions. For example an iPhone X with iOS14.4, I have one and no problem on mine... Here is the stack trace for error: *EXCBADACCESS KERNINVALIDADDRESS* Crash stack - https://developer.apple.com/forums/content/attachment/c3e590ff-9895-48a1-b6a6-a40c659eb398 So, trying my best te fix it, I met a person who have to crash, and try to analyze it. Reproduce it with *NSZombiEnabled* gives me this information: [SwiftUI.AccessibilityNode retain]: message sent to deallocated instance 0x282146760 As it is on a physical device, I can't do many more with instruments, etc... But with *lldb* command line, I tried to know the malloc stack of the implied object. With the following command, (lldb) malloc_info --stack-history --max-frames=256 0x282146760 I have: Malloc history - https://developer.apple.com/forums/content/attachment/f88a0708-c03d-4d8b-8843-5cf69fcadd39 Please, could you give me some directions or indications? Is it a SwiftUI issue? Why do it happens on these devices in particular?

How do I enable core dumps, persistently, in Big Sur. I am more versed in *nix/linux than macOS. I've had a few apps core dump, and see in the 'Console' that they are not permitted to create core files. I've tried 'ulimit -c unlimited' but this hasn't been perspective - perhaps in part as I'm unsure how to get this persistent for all apps (even outside a login shell) on Big Sur. Is there a simple guide to allowing core dumps ie into /cores as I was able to get that working in previous releases...

Hi, im making a daemon swift app for macos that uses the content filter network extension.

As you can see on the log it says "libnetworkextension" so i thought i might have something to do with the network extension but the leak ocurrs even when the NE is not running. I tried looking at the memory graph but when i go to click on the memory address that has the leak all i see is an icon of "OS_dispatch_group". I know this might be not enough information to help me debug this so if you need anything else just let me know.

My app us running in debug mode and I want to display rating popup after user finishes payment and then proceeds further. However If user chooses apple pay then prompt is showing up every time. but if he selects credit/debit card then it doesn't. We are using Braintree service for payments. There is a common screen after payment on which SKStoreReviewController.requestReview api is called. This issue sounds strange but still unresolved.

The problem keeps on manifesting randomly. Every kind of Automation/ actions I set up keeps on failing at random intervals, could be 3 times a day like 1 per month. The problem is evident in Homekit settings that depends heavily on automations and actions to work, like when a Stateless Programmable Switch is used to control smart lights. I've already tried different methods ( logout/login from icloud, reinstall everithing ecc) but the problem keeps on manifesting randomly. When the automation/ action doesn't fire I can check on Home app that the message is processed by homekit but the domestic hub seems not able to run the connected action/automation, and i can control manually every device in the automation to verify that is connected. after 5 to 10 minutes everything starts acting normal again. The problem is present not only with an ATV running the latest firmware but also using an iPad. Is this a well know bug or there's some workaround?

Dear Apple Developers community, Our app is being rejected by the App Store upon review based on detecting crashes upon launch. However, following exhaustive tests on all available simulators and some physical devices (including an iPhone 12 Pro running iOS 14.4.2) we were unable to reproduce the crashes reported. We also tried testing a binary via TestFlight without any issues at all. We also symbolicated our crash reports following Apple's documentation without being able to find any issues that cause the crash upon launch. I am attaching the three reports that Apple Store review shared with us for reference along with the symbolicated outputs for "ParkZen" and "FirebaseFirestore". Our app uses the FireStore database. Any feedback would be greatly appreciated. 1) https://iosapps-ssl.itunes.apple.com/itunes-assets/Purple125/v4/80/06/1e/80061eee-c4c2-2194-c8e1-4cb693546c6a/attachment.crashlog-3B112192-8D8A-44DA-8EB1-0563386C41BB.txt?accessKey=1618848035_6910206807337667898_h6kPaYJOV56xwRkNjjTkztP%2BRq4CQCroN9LS%2BuJKwoV8TAkWCV3X%2Fd9XapTSBt9j%2FEetbrTifhYvaNHpCxXgLFEUQ6Sz68LW1KyUrp7nWwG2TjsZiYj2OAGpVVkYlLzu%2Fz7LVVaPp06PYIdfGEHYFUfe6PuFRUCB8xAnrm%2B0Poq7gYWFy0%2F7%2BkrqMxlbt8TklgbJimfs0F7%2F6ny1oc0yIbhsRNxV0BKp9wH0p85YgsQ%3D 2) https://iosapps-ssl.itunes.apple.com/itunes-assets/Purple125/v4/4f/a5/36/4fa5366a-2ab3-a0f0-9553-4a9b8cc32ab1/attachment.crashlog-E5709224-7BCB-45FC-92F7-E6E1DC7A2BC8.txt?accessKey=1618848035_5419641398235611613_S5R436uDbgLHsLasiTbmzF456qVlLyS6lyoDcbbx%2BSxV0xyzVzA67bNK7A7yftxwisf4gz3%2BjMBHwsyF3ZAeoyStfQA%2BAMENq%2B8%2B2dDa361WfIM%2BbL4toHk5RoyEzlNvaZTC8G65VMy%2BklOlbeTwLUD9HtoTYXnhyjKm4E8CV8hc2MwkwapKANmAlO9RrnEitUWt1qp620c439IN5NpSZmVdEBxYQlSp%2FJqZb33thoM%3D 3) https://iosapps-ssl.itunes.apple.com/itunes-assets/Purple125/v4/47/67/c4/4767c4bc-8820-6264-f8ce-d6464aa6cdeb/attachment.crashlog-2FAC820F-7BBD-428C-8901-BCA3663599BD.txt?accessKey=1618848035_1479893548423628230_JF9xULY4IoBRblEDOeKQZk5borlYARJjnKDlClMbXekl7BWr7Y00E6HKjwz00K3lautGkwCjdVc7khcrNcovUlbaKSI8lSZs3JAxlAvmTgdjzQVAcfYPvc0YQ%2B%2FgDIGUnPZtLiDJRC31XnZ59Yx%2B6Cidvz5%2B590ebu7DdXZ%2BMyevS%2BclcTc2C8Wl48Hq%2F9Bq7DmfcmcIJLJmI%2B1KTe6gq%2FLm%2BQhJoWxDOEpVDV33IsE%3D Symbolicated Debugging: closure #1 in ViewController.viewDidLoad() (in ParkZen) (ViewController.swift:87) closure #1 in ViewController.viewDidLoad() (in ParkZen) (ViewController.swift:87) closure #1 in DatabaseInterface.retrieveData_dynamic(completionHandler:) (in ParkZen) (DatabaseInterface.swift:0) thunk for @escaping @callee_guaranteed (@guaranteed FIRQuerySnapshot?, @guaranteed Error?) - () (in ParkZen) (compiler-generated:0) main (in ParkZen) (ViewController.swift:18) 2) 3)

All the crashes happened when the application is in the background with multiple notifications received even without clicking on the notifications.
