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
