# ReSwifter

ReSwifter is a both a Snippet Manager app and an XCode Editor Extension. It is lightweight, but feature-rich. In addition to typical features found in a Snippet Manager, ReSwifter also offers several local-AI-assisted tasks on your code snippets.

**Note:** This project has no build automation workflows because the GitHub Actions macOS Runner machines' installed SDKs are too old to compile against the FoundationModels framework. See issue: https://github.com/jsbakker/ReSwifter/issues/7

## Features and Behaviour

- New snippets from clipboard are briefly summarized and named automatically

- One-click copy to clipboard, or use keyboard shortcuts

- Live code editing of snippets with syntax highlighting

- Syntax highlighting supports 58 programming languages, which can be overridden

- Adaptive syntax highlighting for Dark and Light modes set by the system

- Folder management, favourites, and search filter assist in finding your snippets

- Folders named after programming languages automatically applies the language's highlighting to new snippets in that folder

- AI-assisted tasks: Explain, Document, Review, Cleanup, Refactor, Convert to Swift*

- AI features use Apple's built-in FoundationModels, which works completely offline (privacy)

- Rich, structured text responses from AI-assisted features (not editable)

- Copy to clipboard button will copy only code blocks from AI responses; use manual selection to copy non-code

\**Note: Accuracy, consistency or reliability of AI-assisted tasks are to be considered with discretion. The language, length, complexity and nature of a snippet, and the AI task can all be combined factors in the quality of the result. Always double-check AI output before accepting it.*

### XCode Extension

- Selected text in XCode can be sent directly to ReSwifter via the Editor menu, and any snippet can be sent back to replace it

- Invoking ReSwifter from XCode with no selection will send the entire contents of the currently opened file, which can be replaced by an augmented version

## Requirements

Apple M1 or later hardware runing macOS Tahoe 26 or later is required. For the AI-assisted capabilities to work, you will need Apple Intelligence enabled (and downloaded) in your System Settings. You may have to restart ReSwifter after the model is downloaded.
