KGN app for iPhone and iPad

This is an example program for my book "Artificial Intelligence Using Swift" (https://leanpub.com/SwiftAI). Knowledge Graph Explorer is written in Swift. It works by accepting natural language processing natural language queries and question answering using two deep learning models, identifying proper nouns like people, places, organizations, etc. This app then attempts to resolve these entity references to linked data on the DbPedia SPARQL endpoint, verifies with the user that it has found the correct entity references, and then attempts to find as much information and relationships between these entities as it can.
