Hello respected sir/ma'am,
My name is Manas and I am a 11th grader and this is my first time creating a playgroundbook. I created an app using Swift Playgrounds 3.3 on macOS Catalina and now when i open the playground book, it shows the layout and i can run my code. But when checking the previous WWDC submissions and example playgroundbooks we find a book view and the code is not visible and we can see it as readonly. How to do we create such a playground!
