I have to thank Nate Cook for first for his quick response and solid answer.
Just for case I share his answer from another post, which title is misleading.
See Nate’s answer here: https://stackoverflow.com/a/26723557/2360439
Playgrounds are sandboxed, so you won’t be able to just grab files from anywhere in your user folder. Here’s how to add that file to your
playground to make it accessible:
- Find your “.playground” file in the Finder Right click and choose “Show Package Contents”
- You should see “timeline.xctimeline”, “contents.xcplayground”, and “section-1.swift”
- Make a new folder called “Resources” if it doesn’t exists yet.
- Copy your files into Resources folder
Seems that there is no way to access files with Swift Playground outside of Playground sandbox. If you know how to access files outside of sandbox, you are welcome to share your solution!!
