Why this release matters

This release marks SwiftFM’s evolution from simple one-shot responses to
supporting real-time generation. Developers can now build more interactive
apps with Foundation Models on-device.

SwiftFM v0.1.1

SwiftFM is a lightweight façade over Apple’s new FoundationModels framework, designed to make working with on-device language models simple and beginner-friendly.

Features

• Plain text generation – pass a prompt, get back a string
• Guided typed generation – decode directly into your own Decodable & Generable structs
• Beginner-friendly API – minimal surface and sensible defaults
• Availability helpers – check if the model is ready on the device
• On-device, no servers required

Requirements

• iOS 26+ / iPadOS 26+ / macOS 26+
• Apple Intelligence enabled on the device or Mac
• Not supported on watchOS or tvOS

Notes

This is the first public release. The API is intentionally minimal, focusing on core use cases:

• generateText(for:)
• generateJSON(for:as:)
• isModelAvailable and modelAvailabilityReason

Expect additional features such as streaming and advanced generation options in future versions.
