if anyone is interested, this was fixed in Beta 4, thanks UIKit Engineers!

bumping this in case anyone has seen this (still an issue in b2)

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.

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

Still an issue in beta 3

still an issue in ios 26.1 b2

still an issue in ios 26.1 b2

i should mention this is with a UITableView line separator

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

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 :)

i would submit a feedback! seems like it would be a bug to me, and i do see them same thing.

ive run into this same issue i think its an actual issue with the segment control in interface builder, ive submitted a feedback but you should as well! If you create the segmented control programmatically it functions fine.

submitted feedback with attached code snippet and system error popup: 15155625

same thing has been happening to me on the simulator, but device is fine

if you click the little +, you can edit your deployment target, by hand, both debug and release, granted looks like they removed the dropdown, but it can still be edited. Also if you goto target - build settings-> deployment you can see your value there and there is a dropdown for ios versions (but only whole version numbers) i suppose if you want to do something like 17.3 or something you'll need to type it in.
