@perlasivakrishna Thanks for sharing this issue with us. So on which iOS SDK version that you saw this crash? I also saw you have included other third-party dependency from your crash report, so could you partition them to see if the crash is still there?

iOS 14.2 I have created a sample project here with the issue. please check it. Thanks.

Hi @perlasivakrishna, thanks for sharing the project. We found the reason for this crash in our FlurryMessaging SDK callback swizzler (NSError was accidentally parsed to @selector(application:didRegisterForRemoteNotificationsWithDeviceToken:) rather than @selector(application:didFailToRegisterForRemoteNotificationsWithError:)). However this wasn't causing any issue in ObjC, and the crash was only reproducible using swift. The fix we put will be released in next GA release in late March. Meanwhile you can either skip the original implementation in AppDelegate.swift for application:didFailToRegisterForRemoteNotificationsWithError: or using ObjC implementation. Let me know if you have any questions.

@perlasivakrishna Please upgrade to v11.2.1 to integrate the fix of this crash
