Am I allowed to use this code online in my WWDC Playground submission?

Link to code: luca-jon.medium.com/create-an-inset-grouped-list-in-swiftui-for-macos-20c0bcfaaa7

I used the code from this post. Am I allowed to use it in my project? Do I have to select YES for the, "Did you use open source software?" question, if I use it.

I also see that this code is hosted on GitHub, so it open source?

Thanks!

Hey, firstly thanks for using my code :)

I think Apple meant real open source frameworks or projects. Things that are standalone software. This is more like a code example. So I would say it does not count as open source software. I also used some code from StackOverflow and do not think that I have to check that.

Hey, thank you so much!
Would this go for any similar tutorial or reference code snippets used? Where would credit need to be given?
