I'm not sure if it's something wrong with my XCode install (Version 27.1, macOS 27.2) or what, because such a serious issue should be mentioned already...
Basically, building my objC app with the latest XCode makes the NSSegmentedControl style ineffective. Likewise, changing the style in the attribute of the control in interface builder has no visible effect on the preview either.
Changing the style in code or in IB has no effect. The control appears stuck with a style that implements a blue background for the selected segment (some default style I guess).
I tried with a minimalistic app that includes only one window and the control. The issue is still present.
Any suggestion? Am I the only one experiencing this?
