AI Chat Screen for SwiftUI — Streaming LLM Chat UI
Description > A drop-in, production-grade streaming chat screen for SwiftUI. Configure it > with one `ChatConfig` struct and point it at any LLM endpoint — OpenAI-style, > Anthropic-style, or any custom SSE server. Streaming tokens, typing indicator, > empty and error/retry states, and full theming are already built. The included > demo runs on a mock service, so it builds and streams with no API key. What's included: - Complete SwiftUI chat screen: message list, input bar, streaming, typing indicator - One-struct `ChatConfig` — no provider hardcoded (OpenAI / Anthropic / custom) - `ChatService` protocol + live `StreamingChatService` + `MockChatService` - `ChatTheme` theming (light / dark / midnight presets) — restyle without forking - Empty, streaming, and error + retry states handled - Typed errors, no force-unwraps, one passing unit test - Runnable Example app (builds and runs with no API key) - README + offline HTML documentation, MIT-style commercial LICENSE - iOS 16+, Swift Package Manager, zero third-party dependencies
