I have tried the methods in the document and the ones you provided. But the return button still cannot be displayed. The method we use now is to listen to the full-screen notification for return. How do I display the back button?

hi Apple So this display is normal, Then I want to use the back button, but it is not available now, right? Will there be a demo for multiview at the same time in the future?

Your method is good. I used a method where I subclassed UIHostingController and overrode its lifecycle methods to resolve the issue.
