Hello, I am new to ARkit.
I have tried to program to display a cube using ARkit and Realitykit in various articles using Xcode, but none of them worked. How can I display a 3Dcube in AR ？？？？？
What I tried, roughly speaking, was to open the xcode iOS, AR progect file and run the program that is included by default.
If you can answer in Japanese, please do so.
