This is a Swift playground implementation of the yarrow stalk oracle using the arc4random_uniform random number generator.

It was originally written in Swift 3 and has been updated to Swift 4.

It is assumed you are on a macOS device capable of installing and running Xcode 9 and above.

Create a folder named Shared Playground Data in ~/Documents.

Launch hexagram_structs.playground in Xcode 9.

//: # Consultation
let 問題: String = ""
// Enter your question within the quotation marks, ending it with a "?".

1. Scroll to the bottom of the playground. You will find the lines shown above.
2. Enter your query between the quotes in the statement let 問題: String = "".
3. To activate the oracle, end your query with a "?".
4. The result will be printed in the console and saved to ~/Documents/Shared Playground Data/ as a markdown file as shown below.
