This works for me, in iOS 16 beta 3. NSArray *array = [[[UIApplication sharedApplication] connectedScenes] allObjects]; UIWindowScene *scene = (UIWindowScene *)array[0]; [self setNeedsUpdateOfSupportedInterfaceOrientations]; [self.navigationController setNeedsUpdateOfSupportedInterfaceOrientations]; UIWindowSceneGeometryPreferencesIOS *geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] initWithInterfaceOrientations:UIInterfaceOrientationMaskPortrait]; [scene requestGeometryUpdateWithPreferences:geometryPreferences errorHandler:^(NSError * _Nonnull error) { }];
