Hi Sorry for late response: I’d like to clarify the relationships here. It seems that you’re building an SDK, and one your SDKs clients is reporting this error. Is that right? Correct We use NSUrlSession Yes we have tried on simulator (wifi connection) but not on real one Vision Pro as we dont have one. We have asked our customer about the network

The SDK talks to a server if the client has a proxy they can redirect by supplying a different url to the SDK. lets us check it

Hi Sorry, I wanted to see if by using proxy we will see the same behavior. So I manage to reproduce it on simulator, without proxy (BUT there is no crash as customer claims) I just see logs of the following: Task <D8BF79FA-F57A-47D8-B491-5A008B69318A>.<2> request https://URL is NOT allowed to set HSTS for main doc (null) Ignoring alt-svc clear Task <D8BF79FA-F57A-47D8-B491-5A008B69318A>.<2> response ended Task <D8BF79FA-F57A-47D8-B491-5A008B69318A>.<2> finished successfully but the request was successful? so should we ignore that log?

I am not sure I fully understand ALL our requests are with HTTPS. So why would HSTS be relevant at all. We see that log ONLY on visionOS. (sorry if misunderstood something )

Any suggestion of how I can map it to a type, I have tried to play with sanitizer tools like zombies etc to see if I get the exact type/object of what causing the error but its still show a memory address. any suggestion of what we can try on our end. (In general I know the place where it happens but I cant tell what exactly cause the issue). I tried to recreate apple dump method (on view controller) and building a minimal tree of all the elements of course there are some internal iOS elements. After creating the tree its get released. The crash doesnt directly happens in my code but rather when view controller get dismissed by user. Any suggestion of how it can be debugged further?

not sure how that suppose to help even if create a link map that will be only for the SDK. the SDK is getting the input from the hosting app in that case its some swiftui object. How a link map of the SDK should help me in that case. I manage to catch the crash on Xcode while debugging why Xcode cant just translate that memory to an object? I mean I can understand why it cant do for the hosting app (the code already compiled and no debug info etc) BUT one of the frames has a deallocated swiftui object why we cant inspect that one? ()

ok so I can see that the binary for devices is maybe encrypted LC_ENCRYPTION_INFO_64 but in that case the error is not descriptive at all EXEC 14 Binary with wrong platform. and cryptid 0 so maybe it means its probably not encrypted

Same here I do see the print to the console but BP doesnt stop

Same here Xcode 15.2 iOS 17.4 Performing a file system operation failed: Failed to open Library/WebKit/WebsiteData/IndexedDB/v0 for reading, openat(2) returned POSIX error code 62 (parentParam = 142) Domain: com.apple.dt.remoteservices.error Code: 11001 Failed to open Library/WebKit/WebsiteData/IndexedDB/v0 for reading, openat(2) returned POSIX error code 62 (parentParam = 142)

Havin the same issue

ok my bad I think I can just ask for the following: [[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSMicrophoneUsageDescription"];

@DTS Engineer Just to clarify: This code is part of our SDK and the SDK is running in hosting app. We already have tried all possible Instruments and didn't see any clue to the problem, please suggest if you have any specific configuration u want us to try The crash happens only for that customer We have submitted a TSI (in addition to current TSI) a year a go and nothing really came out of it Currently we need a solution. I know that's kinda a crash that hard to see (that's why we applied for your help). We attached several crashes with different exception type to provide better picture. With that to say, is there some proper way to recover from those kind of crashes. like try/catch for signals?

@DTS Engineer Any additional info u can provide

Hi, Thanks for your help. Yes Yes Currently one client reported about the issue (I tend to believe there might be more clients with the same issue) wanted to point out that I managed to reproduce the following crash on the client app: Thread 182: EXC_RESOURCE (RESOURCE_TYPE_MEMORY: high watermark memory limit exceeded) (limit=1450 MB) . That happens when the data is to big , it should not happen and we will fix it BUT no guarantee it will solve their issue

@DTS Engineer So initially we tried in our sample apps but that it didnt yield any result. So I took client compiled app, compiled the SDK with Sanitizers and injected it to the client app. (I have linked the ASAN libs to prevent crashes when the app cant find those libs SDK refers to) . I tried mainly the Address Sanitizer tool (it seems like the most appropriate)
