        This issue doesn't happen in iOS 11 or iOS 12. I don't believe it happened in earlier iOS 13 betas. Although it looks like a crash, the app keeps working and getting data. However every time it gets data from the backend the error occurs. Any ideas?

          I have the same issue on a real device.

           

          Also I didn't use any network at all. What I used was only RealmSwift framework.

              I also initially observed it on a physical device. I used the simulators to confirm that it happened only in iOS 13 beta 4, and not on iOS 12 and iOS 11. For me it appears to happen as soon as the app connects to our server.

               

              Hopefully this is just diagnostics and not an indication of a real issue.

                    I'm working on a little project that started showing this error after I started using Realm. It was fine before that.

                    (Using Xcode Beta 4 and SwiftUI)

                        If you go to the Breakpoints menu in the left pane, add a Runtime Issue Breakpoint for System Frameworks and you'll stop when the actual error is happening (and be able to identify the problem library).   Am seeing the same issue in my case from FirebaseInstanceID in

                         

                        - (void)checkinWithExistingCheckin:(FIRInstanceIDCheckinPreferences *)existingCheckin

                                                completion:(FIRInstanceIDDeviceCheckinCompletion)completion

                         

                        and specifically with NSURLSessionDataTask

                         

                         

                        NSURLSessionDataTask *task = [self.session dataTaskWithRequest:request completionHandler:handler];

                         

                         

                        I suspect this is an Apple beta bug so going to report to them but will check out the Firebase side of things too.    Hope that helps.
