## What it does

This plugin connects Claude Code to Apple’s SourceKit-LSP for live analysis of `.swift` files. Claude can inspect diagnostics, jump to declarations, locate symbol references, and retrieve type information.

SourceKit-LSP ships with Xcode. Run `xcode-select --install`, then confirm it is available with `sourcekit-lsp --help`. Swift analysis will not start without SourceKit-LSP installed.

The integration uses the LSP protocol and reacts to file changes. It performs read-only code analysis, with no credentials, network access, or file writes.

## Install

### Claude Code (native platform)

In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install swift-lsp@claude-community
```

## When to use it
- inspect diagnostics in `.swift` files
- jump from a symbol to its declaration
- locate every reference to a function or type
- read type information without building the project

## Example prompts
- Check the current `.swift` file and report its diagnostics.
- Show where this type is declared and jump to its definition.
- Find every reference to this function and explain the related types.

# swift-lsp

Real-time Swift code intelligence for Claude via Apple's SourceKit-LSP.

## What it does

Gives Claude instant diagnostics, go-to-definition, find-references, and type information for `.swift` files — no build step required.

## Setup

1. **Install SourceKit-LSP** (ships with Xcode):
   ```bash
   xcode-select --install
   ```
   Or install the [Swift toolchain](https://swift.org/install) on Linux.

2. **Verify** it works:
   ```bash
   sourcekit-lsp --help
   ```

3. **Install the plugin**:
   ```
   claude plugin install swift-lsp@msapps-plugins
   ```
