bumping this, still an issue with Interface builder segmented controls in beta 4, I would prefer not to rewrite all my views to programmatically add a segmented control :)

this looks to be fixed in beta 5! dont have xcode beta 5 yet to confirm that apps built against beta 5 look good, but apps built against beta 4 running on a device on beta 5 work as expected

i should mention this is with a UITableView line separator

still an issue in ios 26.1 b2

still an issue in ios 26.1 b2

Still an issue in beta 3

this looks to be fixed in B4 !, thanks UIKit Devs!

here is the simple sample code yielding constraint errors : UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithImage:[UIImage systemImageNamed:@"heart"] style:UIBarButtonItemStylePlain target:self action:@selector(heartTapped:)]; self.navigationItem.rightBarButtonItem = button2; nothing crazy.
