Upon opening RW tutorial playground files, I see you guys add a description area into the playground. This description area contains text and image, and not interfere with the code. I want to ask how to insert that area ?
Please see picture attached for example. In this picture, description part I mentioned is from “Challeng 2” down to first line of code “var tree: BinaryNode…”.
Glad you found that, now with XCode 11, it will also create documentation from the functions signature. We’ll leave that for a series of tutorials to come on all the new shiny stuff released at WWDC.
