One of our customers provided us with stack log crash . The crash is coming from within the SDK. It seems that the crash start to happen on iOS 15. (We were unable to reproduce it on the simulator and haven't tried it on device yet) We would like to have more insights about the crash and its reason as according to the reference refernce there is no Termination Reason or Code.

Attaching several crash traces: 2024-02-29_22-48-33.6864_-0600-3f948243e21b4c68d77a38d9cf1cecfdfe2c1565.crash 2024-03-04_15-00-02.9335_-0600-75000cd5acd63ba1434f2ffb3648b97259dddb88.crash 2024-03-05_08-55-47.2097_-0500-f682b25663107ad46f091d65f402f2be31f3f3c6.crash 2024-03-11_08-09-00.4057_-0400-e37d1a635d51afbb67ac38b42dd79c1718a408e8.crash 2024-03-15_16-20-22.6446_-0600-d4ebccf455e8305038ca564a39a5661a1dce6231.crash The final code: - (NSObject*)objectAtIndex:(NSUInteger)index { if (index < self.count) { return [self.embeddedArray objectAtIndex:index]; } else { [PNDErrorReporting reportError:PNDErrorReasonTypeSafeCollectionCrashPrevented message:@"Error msg"]; return nil; } } We subclass NSMutableArray to prevent potential crashes. but we encounter a new crash in our sdk for one of the clients. Also we noticed the stack trace skipped one of the frames (stack calls) in the crash report, in which cases the stack trace wont be identical to the actual code (beside inline)?

One of our client has contacted us with the following error : Task .&amp;lt;3&amp;gt; request https:URL is NOT allowed to set HSTS for main doc (null) Th request is sent from our SDK. According to the client it happens only on Vision Pro. All our requests to the server on the SDK side are https. The serve has the following header: X-Content-Type-Options X-Frame-Options Strict-Transport-Security Can somebody share some insight?

if we define a property in the following way: @property (atomic) NSString *latestObject; Can we assume that the read write to that value is thread safe? i.e the value will be correct. Or it is better to write our own setter/getter with Locks?

It seems that that all the crashes are coming from the same place BUT the error is slightly different. Attaching the code that responsible for the crash: static NSString * const kDelimiter = @"#$@"; + (PNDArray *)getObjectsFromData:(NSData *)data { NSString *dataStr = [[NSString alloc] initWithData:data encoding:encoding]; dataStr = [dataStr stringByReplacingOccurrencesOfString:@"\\u0000" withString:@""]; NSArray *components = [dataStr componentsSeparatedByString:kDelimiter]; NSMutableArray *result = [NSMutableArray array]; for (NSString *jsonStr in components) { if (jsonStr != nil && jsonStr.length != 0 && ![jsonStr hasPrefix:kBatchUUID]) { [result addObject:jsonStr]; } } return [PNDArray arrayWithArray:result]; } 2024-04-16_17-15-34.1922_-0600-dfa2faecf702f23e3f6558bea986de4f62851761.crash 2024-04-24_04-56-53.4664_-0500-6b125d3d03b7e497b6be339c2abb52f29658824b.crash 2024-04-25_11-13-53.1326_-0700-bfe370be3eae8d65f465eac714905dd3d13aa665.crash 2024-05-03_11-47-36.6085_-0500-2793587e7ed1c02b0e4334bbc3aa0bd7f7a0cf3d.crash 2024-05-05_10-49-40.5969_-0700-4d86636b0877fceb8c0cdb9586ee16dfb0a9c934.crash
