My current solution is, to remove the "Edit" button from the UiTabBarController programmatically, but this removes the functionality itself.
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
//======================================================================================
// as iOS 26.0 and 26.1 is crashing when moving the entries in the TabBarController Edit
//
// Has to be checked as soon it is working again, this code should be removed
//
if (@available(iOS 26.0, *)) {
UINavigationBar *morenavbar = navigationController.navigationBar;
UINavigationItem *morenavitem = morenavbar.topItem;
/* We remoce Edit button in More screen. */
if (morenavitem.rightBarButtonItem.action == @selector(beginCustomizingTabBar:)) {
morenavitem.rightBarButtonItem = nil;
}
}
//======================================================================================
