I am running my code in
Version 10.2.1 (10E1001). I believe I’ve copied it all down correctly, but nothing is showing up when the playground runs. I’ve restarted xcode and it still doesn’t work.
Moreover, when I run the code that comes with the book, it also doesn’t work. Not sure how to dig into this, or if it is a known problem?
Thank you for any pointers.
