I am using Xcode Playgrounds to make tutorials about Swift. I was wondering, can I put multiple playground files into one Xcode workbook? I want one workbook with multiple playground tutorials in it.
You can right click on your top level file and select the "New Playground Page" button, which will give you a separate page.
The below image shows the new page created after you click that button. "Untitled Page" is the initial page, and "Untitled Page 2" is the new page.
