Super excited to read this book! If you’re like me and are already completely lost in chapter 1 at: The **Sources** section of the playground contains **Files.swift** , which holds functions for saving and reading the sample data. Expand the **Sources** section, if it’s not already expanded, and open **Files.swift**. and can’t find the Files.swift, in Xcode, click on View → Navigators → Show Navigator (or CMD-0 that’s zero). ---

Hi. I hope you enjoy the book. Thanks for this clarification. I’ll see if I can add a note to the book. ---

Congrats on the new book. Here is a minor detail that might help others. I didn’t see the play button, but it was my own fault. The text clearly says to " Save **Files.swift** and return to the playground page." I didn’t return to the playground page, so I didn’t see the play button. User error. ---

I could not get pbpaste to work. It is possible that the single line in SampleData.json is too big at over 130000 characters. On my iMac, “getconf ARG\_MAX” returns 1048576. What worked for me in Terminal was: > cd ~/Downloads > cat SampleData.json | json\_pp \> SampleData.pretty.json > cp SampleData.json SampleData.original.json > cp SampleData.pretty.json SampleData.json Xcode 13.3.1, macOS 12.3.1, iMac 2017. Default shell in terminal: bash (because I have many years with it). ---

That’s strange. I’ve tested this on `zsh` and `bash` and they both work. My `getconf ARG_MAX` also returns 1048576 so it can’t be that. But your workaround will do the job, so thanks for posting it for anyone else who has the same problem. ---

After your response, I tracked this down and embarrassingly it is dumb user. I had done the Command-A to select the whole, original JSON file, but neglected the Command-C to put it in the clipboard. pbpaste does work for me if used correctly. Thanks for looking and sorry for wasting your time.
