[Bug]: NSInvalidUnarchiveOperationException *** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (OSIndirectNotification) for key (NS.objects) because no class named "OSIndirectNotification" was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target). If the class was renamed, use setClassName:forClass: to add a class translation mapping to NSKeyedUnarchiver
