SwiftEliza is a Swift + iOS implementation of Weizenbaum's ELIZA chatbot, which is a simulation of a Rogerian psychotherapist.
Based on my Go implementation and QuestionBot from Apple's App Development with Swift book.
To run, just open the SwiftEliza.xcodeproj in XCode.
The functionality of ELIZA is contained in the Eliza.swift file, and the rest are boilerplate for the iOS app.
Written in Swift 3 for iOS 10 and above.
