Quaynor's Swift binding is distributed through Swift Package Manager for iOS and macOS. Swift Package Manager, usually shortened to SwiftPM, is Apple's package manager for Swift and Xcode projects. The package downloads the published QuaynorFFI.xcframework from GitHub Releases, so consumers do not need a local Rust toolchain.

Install

Add the package in Xcode with:

• URL: https://github.com/iBz-04/quaynor.git
• Dependency rule: Up to Next Major Version
• Version: 0.1.2

Or declare it in Package.swift:

dependencies: [
    .package(url: "https://github.com/iBz-04/quaynor.git", from: "0.1.2")
]

Use it

The package exposes:

• Model
• Chat
• TokenStream
• Encoder
• CrossEncoder
• SamplerPresets
• Prompt
• Tool
• CachedModel
• ChatStats

That means Swift supports model loading and downloads, chat, streaming, embeddings, reranking, tokenization, chat stats, cache inspection, cache deletion, and tool calling through the wrapper API.

Example:

import Quaynor

let model = try await Model.load(
    modelPath: "hf://bartowski/Qwen_Qwen3-0.6B-GGUF/Qwen_Qwen3-0.6B-Q4_K_M.gguf"
)
let chat = Chat(model: model)
let answer = try await chat.ask("Is a zebra black or white?").completed()
print(answer)

Download progress, cache inspection, and cache deletion are available directly on Model:

let localPath = try await Model.downloadModel(
    modelPath: "hf://bartowski/Qwen_Qwen3-0.6B-GGUF/Qwen_Qwen3-0.6B-Q4_K_M.gguf"
) { downloaded, total in
    print("\(downloaded) / \(total)")
}

let cachedModels = try Model.getCachedModels()
for model in cachedModels {
    print("\(model.path) (\(model.size) bytes)")
}

let deletedBytes = try Model.deleteCachedModel(modelPath: cachedModels[0].path)
print("Deleted \(deletedBytes) bytes")
print(localPath)

deleteCachedModel only accepts paths inside Quaynor's model cache. It returns the number of bytes removed and throws if the path is outside the cache or the model is still loaded.
