MCP Tools for Swift Development

Model Context Protocol servers for enhanced Swift/Xcode workflows.

Available MCP Servers

1. XcodeBuildMCP

Purpose: Xcode project automation and build validation

Documentation: xcode-build-mcp.md

Key features:

• Discover Xcode projects and workspaces

• Build for macOS, iOS Simulator, iOS Device

• List schemes and show build settings

• Clean builds and derived data

• Create new projects from templates

• Autonomous build validation (AI can build, read errors, fix, rebuild)

Installation:

{ "mcpServers": { "XcodeBuildMCP": { "command": "npx", "args": ["-y", "xcodebuildmcp@latest"] } } }

Use when:

• After making code changes (MANDATORY validation)

• Debugging build issues

• Creating new Xcode projects

• Cleaning stale builds

2. Apple Docs MCP

Purpose: Official Apple documentation with offline WWDC access

Documentation: apple-docs-mcp.md

Key features:

• Search all Apple frameworks (SwiftUI, UIKit, Foundation, etc.)

• Get detailed symbol information (classes, methods, properties)

• WWDC sessions 2014-2025 with full transcripts (offline)

• Access Apple sample code

• Framework exploration and discovery

• API availability and deprecation checking

Installation:

{ "mcpServers": { "apple-docs": { "command": "npx", "args": ["-y", "@kimsungwhee/apple-docs-mcp"] } } }

Use when:

• Researching Apple APIs (PRIORITY over Context7)

• Finding WWDC best practices

• Checking API availability

• Getting official code examples

Workflow Integration

Research-First (MANDATORY)

Priority order:

1. ⭐ Apple Docs MCP (official Apple docs + WWDC)
2. Context7 (third-party libraries)
3. Exa web search (community tutorials)

Build Validation (MANDATORY)

After EVERY code change:

1. XcodeBuildMCP: Build project
2. If errors → Read error messages
3. Fix issues
4. Rebuild to validate
5. Only commit if zero errors

Complete Development Workflow (2026)

1. Feature request received ↓
2. Apple Docs MCP: Search API/WWDC ↓
3. Read existing codebase (DRY principle) ↓
4. Implement following Apple patterns ↓
5. XcodeBuildMCP: Build to validate ⭐ ↓
6. If build errors:
   • Read error messages
   • Fix issues
   • Rebuild ↓
7. Run tests (if available) ↓
8. Commit changes

Benefits

XcodeBuildMCP

Apple Docs MCP

✅ Official Apple documentation (most accurate) ✅ WWDC sessions offline (2014-2025) ✅ Zero network latency ✅ Complete API coverage ✅ Deprecation and availability info
