SwiftInk

SwiftInk is, as the name suggests, a Swift port of the runtime engine for the ink scripting language by inkle.

For now, it should be assumed to be unstable!

Documentation

Until a first version is complete, the code for SwiftInk will follow the C# engine very closely. This means that the official Running Your Ink documentation from inkle should be easily translatable into SwiftInk's API.

Differences from C# version

To fit Swift language conventions, SwiftInk uses pascalCase for method names and enumeration cases instead of CamelCase as C# does.

Here's a basic "engine" for playing Ink scripts:

let story = try Story(jsonString)
while true {
    print(try story.continueMaximally())
    if !story.currentChoices.isEmpty {
        for (i, choice) in s.currentChoices.enumerated() {
            print("\(i): \(choice.text!)")
        }
        
        var playerChoice: Int? = nil
        while playerChoice == nil {
            playerChoice = Int(readLine() ?? "0")
        }
                    
        try s.ChooseChoiceIndex(playerChoice!)
    }
    else {
        print("Story complete!")
        break
    }
}
