Hi, I am writing apps in C++ and Objective-C.
I created an instance of ASWebAuthenticationSession and set the presentationContextProvider. Then when I started the session, the app crashed with EXC_BAD_ACCESS (KERN_INVALID_ADDRESS).
When I checked the crash log, I found an exception in [SFSafariViewController _setEdgeSwipeDismissalEnabled:]. But since this method is defined within the iOS framework(Xcode13.2.1), I don't know which field is causing the crash.
I've done some testing, but I don't get much information :
-I have enabled "Zombie Object" and "Address Sanitizer",however I was unable to get any additional information.
-I tried to create a new project and used ASWebAuthenticationSession with the same arguments, but I could not reproduce the problem.
Can someone please help or any other advice on finding the reasons for this error?
