A modern, type-safe Swift library for building AI-powered applications on iOS and macOS. SwiftAI provides a unified API that abstracts away complexities of integrating with various AI models, from Apple's on-device capabilities to cloud-based services like OpenAI, enabling developers to build robust LLM features efficiently.

How It Works

SwiftAI employs a model-agnostic design, offering a single interface to interact with diverse AI backends including Apple's on-device models, OpenAI, MLX, and custom solutions. Its core innovation lies in strongly-typed, structured output generation with compile-time validation, ensuring data integrity. The library leverages modern Swift concurrency (async/await) for asynchronous operations, supports real-time streaming responses, and provides first-class features for agent tool use and stateful chat conversations.

Quick Start & Requirements

• Installation: Swift Package Manager. Add https://github.com/mi12labs/SwiftAI to your project.
• Prerequisites: Standard Swift development environment. For the MLX backend, additional dependencies (SwiftAIMLX, MLXLLM) are required.
• Links: SwiftAI GitHub

Highlighted Details

• Model Agnostic API: Seamlessly switch between on-device (SystemLLM, MLX) and cloud (OpenAI) models without code changes.
• Type-Safe Structured Output: Define Swift structs that the AI can generate directly, with compile-time validation.
• Streaming API: Supports real-time, progressive generation of text and structured data.
• Agent Tool Loop: First-class integration for AI to call external tools and functions.
• Conversations: Stateful chat sessions with automatic context management.
• MLX Backend (Experimental): Integrates local LLMs via Apple's MLX framework.

Maintenance & Community

The project is developed for the Swift community with a link to contributing guidelines. Specific details on active maintainers, community channels (like Discord/Slack), or a public roadmap are not detailed in the README.

Licensing & Compatibility

Released under the MIT License, permitting broad use, modification, and distribution, including for commercial purposes.

Limitations & Caveats

SwiftAI is currently in Alpha status, indicating potential for rough edges and breaking changes. Structured output generation is not yet supported when using the experimental MLX backend.
