I have this app which uses 2 UISplitViewControllers on 1 screen (landscape mode). All is working fine on iOS 12, but on iOS 13 the screen is wrong on 9,7 iPads, perfect on the bigger iPads.I have made some sample code to explain. All code, no storyboard stuff. All in AppDelegate.m :- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { UIViewController *right = [[UIViewController alloc] init]; right.view.backgroundColor = [UIColor blueColor]; UIViewController *middle = [[UIViewController alloc] init]; middle.view.backgroundColor = [UIColor greenColor]; UIViewController *left = [[UIViewController alloc] init]; left.view.backgroundColor = [UIColor yellowColor]; UISplitViewController* rightSplitViewController = [[UISplitViewController alloc] init]; rightSplitViewController.viewControllers = [NSArray arrayWithObjects:middle, right, nil]; UISplitViewController* splitViewController = [[UISplitViewController alloc] init]; splitViewController.viewControllers = [NSArray arrayWithObjects:left, rightSplitViewController, nil]; self.window.rootViewController = splitViewController; return YES;}I create 3 UIViewControllers, give them a different background color. I create 2 UISplitControllers and fill it with the UIViewControllers. Normally you should have your screen with 3 columns, in 3 colors, but on the 9,7 inch iPads you only get 2 columns.This is how it looks on the iPad Pro 11 inch and 12,9 inch : http://www.waiterone.net/11-inch.pngThis is how it looks on the iPad Pro 9,7 inch and the iPad Air : http://www.waiterone.net/9.7-inch.pngWhat is going on? Bug in iOS 13? How can I solve this?
