 The `SAPCAI` Swift Package is a module to connect to a bot on the end-to-end chatbot platform [SAP Conversational AI](https://www.sap.com/products/conversational-ai.html) (CAI). It provides a pluggable SwiftUI `AssistantView` to initiate a conversation and render the various [message types](https://help.sap.com/viewer/a4522a393d2b4643812b7caadfe90c18/latest/en-US/ad3681adae824f8a96cbcf8b889a4ffc.html) of a bot.
 
 This Swift Package is an open-source addition to the [SAP BTP SDK for iOS](https://developers.sap.com/topics/sap-btp-sdk-for-ios.html).
