Navigation bar Navigation Navigation elements, as a result of which the upper area of ​​the buttons on the pushed view controller cannot be unavailable

I have a strong feeling that this may be a bug with Xcode, which Apple is just fixing. I have a view controller built into the navigation controller as the root controller. The view controller has a button that is vertically aligned with the top guide. The view controller button works fine, and the entire area to be displayed works.

enter image description here

However, if I push the same or a similar view controller onto the navigation stack, it will not be fully displayable. The top of the button (about 10 pixels or so) can no longer be displayed. If I try to click in the upper left corner of the button, the "Back" button on the navigation panel will be pressed instead, although I do not explicitly touch the borders of the navigation panel. I suppose this is an apple bug, but I was wondering if anyone knew about the fix. Here is a link to the github project if anyone needs it.
