Is the Swift REPL suitable for running entire applications?

No, the REPL is designed for testing isolated Swift snippets, verifying logic, and exploring API behaviors rather than executing a full app project.

Do I need Xcode installed to use this skill?

Yes, this skill requires Xcode 26.3 or later and the Xcode MCP server (mcpbridge) to be configured and active on your system.

Does this skill work with the Codex CLI?

No, this specific skill is exclusively designed for use with the Xcode MCP server and is not compatible with the Codex CLI.

Can I view SwiftUI previews directly in the Claude chat?

Yes, the RenderPreview function allows Claude to generate and display preview images of your SwiftUI views for immediate visual feedback.

How do I set up the required Xcode MCP server?

You can add the necessary server by running the command 'claude mcp add xcode -- xcrun mcpbridge' in your terminal.

Mobile Development

Accelerates iOS development by enabling SwiftUI preview rendering, Swift code execution, and Apple documentation searches directly within the Claude interface.

This skill integrates Claude with the Xcode environment via the MCP server to provide a high-efficiency iOS development workflow. It allows developers to visualize SwiftUI layouts without leaving the terminal, test Swift logic instantly through an interactive REPL, and access official Apple documentation to verify API usage or framework behavior. By bridging the gap between AI-driven code generation and the local Xcode toolchain, it streamlines UI debugging, algorithmic prototyping, and technical research, provided the Xcode MCP server is active.

Key Features

01Direct integration with Xcode via the MCP bridge

02Interactive Swift REPL for instant code snippet execution and logic testing

03Integrated Apple documentation search for rapid API discovery

04Real-time SwiftUI preview rendering for visual UI verification

05Automated visual validation of layout and component changes
