Swift Chat AI Starter

Swift Chat AI Starter is an open source iPhone application that streams responses from the Anthropic Claude API using the Swift Chat assistant interface style.

Swift Chat AI Starter is a template application that allows users to build an iPhone chat interface. The app utilizes the Swift Chat library to display user questions at the top of the screen while streaming Claude responses in Markdown format below. It handles chat threads by appending replies and updating text as tokens arrive. Users provide their own Anthropic API key via the app interface to authenticate requests. The application supports image attachments for analysis by Claude. Developers can modify the codebase to route API requests through a backend server instead of direct client-side calls before shipping to others.
