I just created a new Xcode project, and only selected portrait orientation, but when I rotate my iPhone, it shows the landscape view as well. Any idea why?

Device Orientation Bug
I do not see anything on your screen that shows rotation. It looks like a uniform color screen. What am I missing ?
I did repeat the test on an app, with Xcode 13 and iOS 15 (simulator), it works correctly.
I think it's a bug that GUI operations don't work. Currently it can be changed in Custom iOS Target Properties on the Info tab.
