Summary

SwiftAI A modern, type-safe Swift library for building AI-powered apps. SwiftAI provides a unified API that works seamlessly across different AI models - from Apple's on-device models to cloud-based services like OpenAI. ✨ Features 🤖 Model Agnostic : Unified API across Apple's on-device models, OpenAI, Anthropic, and custom backends : Unified API across Apple's on-device models, OpenAI, Anthropic, and custom backends 🎯 Structured Output : Strongly-typed structured outputs with compile-time validation : Strongly-typed structured outputs with compile-time validation 🔧 Agent Tool Loop : First-class support for tool use : First-class support for tool use 💬 Conversations : Stateful chat sessions with automatic context management : Stateful chat sessions with automatic context management 🏗️ Extensible : Plugin architecture for custom models and tools : Plugin architecture for custom models and tools ⚡ Swift-Native: Built with async/await and modern Swift concurrency 🚀 Quick Start import SwiftAI let llm = SystemLLM ( ) let response = try await llm . reply ( to : " What is the capital of France?
