An official Apple plugin has turned up in Claude Code's official plugin directory. One command installs it — /plugin install xcode@claude-plugins-official — and it needs a current Xcode on a Mac.

Once installed, Claude Code can build, run and test a scheme, render SwiftUI previews, drive simulators and real iPhones, read build logs and search Apple's developer documentation. That lets the agent see what an app looks like and fix it without the developer tabbing back to Xcode.

Apple has put out no press note. The marketplace entry, which lists Apple Inc. as its author, was merged into Anthropic's claude-plugins-official repository on November 6, and the entry does not ship a separate download: it runs xcrun on the Mac and uses whatever plugin the installed Xcode ships.
