In this replay, members of the Watson Developer Cloud Swift SDK development team walk you through the process of building Swift apps that use Watson and also introduce you to some application demos that use the SDK. They demonstrate Cognitive Concierge, a restaurant recommendations app written entirely in Swift, which is built using the Kitura web framework and uses the Swift SDK to integrate the Watson Conversation, Speech to Text, and Text to Speech services to enable a conversation with Watson. The Alchemy Language API is used to analyze positive and negative sentiments in reviews, which helps the user decide which restaurant they should go to.
