swift-lsp · msapps-mobile — Claude Code plugin: Swift analysis, setup
Adds SourceKit-LSP support to Claude Code for Swift diagnostics, symbol navigation, reference search, and type details without a build.
/plugin marketplace add anthropics/claude-plugins-community
/plugin install swift-lsp@claude-communityWhat swift-lsp 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.
What it helps with
- inspect diagnostics in
.swiftfiles - jump from a symbol to its declaration
- locate every reference to a function or type
- read type information without building the project
Example prompts for the agent
- Check the current
.swiftfile 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.
